    On the basis of certain fundamental data on the maturation processes of the central auditory pathways in early childhood the importance of early intervention with hearing aids is discussed and emphasized. Pathological hearing, that is acoustical deprivation in early childhood will influence the maturation process. Very often speech development is delayed if diagnosis and therapy or rehabilitation are not early enough. Anamnesis, early diagnosis and clinical differential diagnosis are required before a hearing aid can be fitted. Selection criteria and adjustment parameters are discussed, showing that the hearing aid fitting procedure must be embedded in a complex matrix of requirements related to the development of speech as well as to the cognitive, emotional and social development of the child. As a rule, finding and preparing the "best" hearing aids (binaural fitting is obligatory) for a child is a long and often difficult process, which can only be performed by specialists who are pedo-audiologists. After the binaural fitting of hearing aids an intensive hearing and speech education in close cooperation between parents, pedo-audiologist and teacher must support the whole development of the child.

    Full Text Available Background and Aim: Hearing impairment can have an impact on adolescents’ quality of life and can lead to their isolation and depression. The main purpose of this research was to study the effectiveness of a mental rehabilitation program based on positive thinking skills training on increasing happiness in a group of hearing impaired girls and boys.Methods: In this experimental study, pre- and post-test plan with a control group was used. All of the hearing impaired students (girls and boys in all high schools of southern parts of Tehran, Iran, in year 2012-13 were our statistical research community. 48 hearing impaired girls and boys were selected by multistage sampling including stratified, purposive, and random sampling. They were randomly divided into two groups of experimental and control. Each group consists of 12 boys and 12 girls. Positive thinking skills were trained to experimental groups during eight 45-minutes sessions, twice a week. We used the Oxford happiness questionnaire to assess the level of happiness.Results: Using analysis of covariance showed that positive thinking skills training had meaningful and positive effect on increasing happiness of hearing impaired boys and girls in the experimental groups (p<0.01. Also, the mean happiness scores of boys and girls were meaningfully different (p<0.01.Conclusion: Positive thinking skills training increases the happiness scores of hearing impaired adolescents. So, the approach taken in this study can be considered as an appropriate method for psychological-education interventions, counseling and treatment in hearing impaired adolescent.

    Full Text Available ABSTRACT Purpose: to analyze auditory and oral communication behaviors in a group of children and adolescents, users of cochlear implants and to establish a relationship with factors that interfere with aural rehabilitation. Methods: participants were 13 children or adolescents with profound bilateral sensorineural hearing loss. Standardized procedures were applied to check: the auditory and oral communication behaviors of participants and their relationships with the child's age at diagnosis period; the interval between diagnosis and intervention, adaptation onset of the cochlear implant; the hearing age and aural rehabilitation period. Results: statistically significant data were found to correlate the interval between diagnosis and intervention with the scores in the evaluation procedures of oral communication. Conclusion: there was a significant impact on the development of oral communication when the period elapsed between the diagnosis and intervention was analyzed, in such way that the faster the intervention time, the better the results. It was also evident that the earlier the beginning of the use of cochlear implants, the greater the hearing age, and the longer the rehabilitation period, the better the scores in the procedures that evaluated auditory and verbal development.

  8. Hearing and Cognitive Impairment and the Role of the International Classification of Functioning, Disability and Health as a Rehabilitation Framework

    2016-01-01

    The International Classification of Functioning, Disability and Health (ICF) has been applied widely in the literature to describe and differentiate the broad implications of hearing impairment (HI) and cognitive impairment (CI) on communication. As CI and HI are largely age-related conditions, the likelihood of comorbidity of these conditions is high. In the context of an aging population, the prevalence of comorbidity is likely to rise, yet much of the clinical assessment and intervention in HI and CI occur separately. The benefit of addressing the dual impact of these conditions is of increasing clinical importance for all clinicians working with older adults and for audiologists and speech pathologists in particular. In this article, the ICF model will be applied to explore the everyday implications of HI and CI. Furthermore, the clinical implications of the ICF model are explored with particular respect to communication assessment and intervention options. The potential benefit of combining activity- and participation-focused interventions currently offered for HI and CI independently is examined. PMID:27489399

    Programmes for early childhood childhood hearing impairment identification allows to quickly start the appropriate hearing aid fitting and rehabilitation process; nevertheless, a large number of patients do not join the treatment program. The goal of this article is to present the results of a strategic review of the strengths, weaknesses, opportunities and threats connected with the audiologic/prosthetic/language follow-up process of children with bilateral permanent hearing impairment. Involving small children, the follow-up includes the involvement of specialised professionals of a multidisciplinary team and a complex and prolonged multi-faced management. Within the framework of the Italian Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for Early Identification, Intervention and Care of Hearing Impaired Children", the purpose of this analysis was to propose recommendations that can harmonise criteria for outcome evaluation and provide guidance on the most appropriate assessment methods to be used in the follow-up course of children with permanent hearing impairment. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale.

    Full Text Available Individuals with hearing impairment are confronted with a lot of problems due to the condition of their disability. This has a negative impact on their social and psychological well-being with multiplying effect on their interpersonal relationship. Therefore, this study investigated the psycho-social influence of hearing impairment on interpersonal behavior of youths with hearing loss.MethodologyThe study adopted a survey research design. A sample consisting of 211 participants with hearing loss were purposively selected from the Federal College of Education (Special Oyo, Nigeria. A questionnaire, part of Psycho-social Competence Scale (PCS, was used for data collection with reliability coefficient of 0.72.ResultsThe findings revealed that hearing impairement affects social interaction of youths with hearing impairment, hearing loss affects emotional well-being of youths with hearing impairment and youths with hearing impairment feel inferior in company of persons without hearing impairment. Based on this, it was recommended that a friendly home environment should be made and youths with hearing impairment should be advised to accept their loss and take it as a challenge that can be used to achieve a better end and the society should have right attitude and beliefs toward youths with hearing impairment.

    Hearing-impaired children's chances of integrating into hearing society largely depend on their parents, who need to learn vast amounts of science knowledge in the field of hearing. This study characterized the role played by science knowledge in the lives of nonscientists faced with science-related decisions by examining the interactions between general science knowledge, contextual science knowledge in the field of hearing, and parents' advocacy knowledge and attitudes. Based on six semi-structured interviews and 115 questionnaires completed by parents of hearing-impaired children, contextual science knowledge emerged as the only predictor for having slightly better advocacy attitudes and knowledge (5.5% explained variance). Although general science knowledge was the best predictor of contextual knowledge (14% of explained variance), it was not a direct predictor of advocacy knowledge and attitudes. Science knowledge plays some role in the lives of hearing-impaired families, even if they do not list it as a resource for successful rehabilitation.

    Technological expansions have been observed in recent years for portable devices with hi-fi audio playback capability such as MP4 players, multimedia phones and hand-held game consoles. Usually these devices are used with headphones; therefore the noise levels of different headphones are of particular relevance. Despite of its several benefits, noise levels can be quite high and may cause hearing impairment. In this research, different headphones were selected to check noise levels at varying volumes. It was found in majority of cases that noise levels ranged from 75dB to 85 dB; surpassing the NEQ's and OSHA standard values. (author)

    Full Text Available Hearing impairment has far reaching consequences for affected individuals, in terms of quality of life indicators. In a developing South African context the hearing impaired population is faced with limited aural rehabilitation services. This study evaluated self-reported outcomes of aural rehabilitation in a group of adults in the public healthcare sector with a standardized outcomes measurement tool (IOI-HA. Sixty-one respondents participated (44% males; 56% females, with a mean age of 69.7 years. Results revealed that the majority of respondents experienced favourable outcomes in all domains of the inventory comprising of: daily use of hearing aids, benefits provided by hearing aids, residual activity limitation, satisfaction with hearing aids, residual participation restriction, impact of hearing difficulties on others, and changes in quality of life. Statistically significant relationships were obtained between the daily use of hearing aids, the degree of hearing loss, and the type of hearing aids fitted, as well as the benefits received from hearing aids in difficult listening environments (p < 0.05. Despite challenges of developing contexts, the mean scores distribution compared positively to similar reports from developed countries. Outcomes of improved quality of life emphasize the importance of providing affordable hearing aids and services to all hearing impaired individuals in South Africa.

    The causes of Permanent Childhood Hearing Impairment (PCHI) are often quoted as being hereditary in 50%, acquired in 25%, and unknown in 25% of cases. Interest in the causes of PCHI has grown recently due to increasing diagnostic possibilities. We investigated the evidence for the reported distribution of these causes. Population-based study and a systematic review. Inclusion criteria for population-based study: children born between 2003 and 2005, resident in The Netherlands at birth, known at an Audiology Center with PCHI at the age of 3-5 years. The causes of PCHI were determined prospectively by detection of congenital cytomegalovirus on dried blood spots and/or genetic diagnostic investigations in addition to reviewing data from medical records. A systematic review was carried out using three terms (hearing loss, infant, and etiology) and limited to articles published between January 1997 and July 2009. Main outcome measures were: the (weighted) proportions of the various causes of PCHI following diagnostic investigations. In the study-population (n = 185) a hereditary cause was found in 38.9%, acquired cause in 29.7%, miscellaneous cause in 7.1%, and the cause remained unknown in 24.3%. The systematic review of the literature (n = 9 articles) resulted in a weighted mean of 30.4% hereditary, 19.2% acquired, and 48.3% unknown causes of PCHI. The systematic review and the results of the population-based study provided little support for the generally accepted distribution of causes of PCHI.

    Full Text Available Background: Reading is known as one of the most important learning tools. Research results consistently have shown that even a mild hearing impairment could affect the reading skills. Due to the reported differences in reading comprehension skills between hearing impaired students and their normal hearing peers, this research was conducted to compare the differences between the two groups. The other aim was to find any changes in the reading ability of hearing impaired group during elementary school. Methods: This study is a cross-sectional (descriptive–analytic one in which reading comprehension ability of 91 students with severe and profound hearing impairment (33 girls and 58 boys from 2nd up to 5th grade of exceptional schools were compared with 50 2nd grade normal hearing students in Ahvaz, Iran. The first section of Diagnostic Reading Test (Shirazi – Nilipour, 2004 was used in this study. Then the mean reading scores of hearing impaired students in each grade was compared with control group using SPSS 13 with Mann Whitney test. Results: There was a significant difference between average scores of hearing impaired students (boys and girls in 2nd to 5th grade with normal hearing students of 2nd grade (P<0.001. Reading comprehension scores of students with hearing impairment in higher grades had improved slightly, but it was still lower than that of the normal hearing students in the 2nd grade. Conclusion: It appears that reading comprehension skill of students with significant hearing impairment near the end of elementary school years becomes weaker than normal hearing students in the second grade. Therefore, it is essential to find and resolve the underlying reasons of this condition by all professionals who work in the field of education and rehabilitation of these students.

    Full Text Available Background and Aim: Grammatical skills development of hearing-impaired children depends on using appropriate educational rehabilitation programs. This study aims to investigate the effectiveness of linguistic plays on the grammatical skills in hearing-impaired children with hearing aids.Methods: Ten hearing-impaired children with hearing aids, aged between 5 and 7, were randomly assigned to two groups (5 children in each group. Each treatment group received 12 sessions on linguistic plays. The grammatical skills of these children were evaluated via the TOLD-P: 3 (Persian version; in addition, their level of intelligence was assessed by the Raven test.Results: The difference between the scores of both control and treatment groups revealed a statistically significant difference in grammatical skills (t=7.61, p=0.001 and three subskills of the children who participated in the linguistic plays. These subskills include syntactic understanding (t=3.16, p=0.013, sentence imitation (t=1.71, p=0.006, and morphological completion (t=6.55, p=0.001. In other words, the findings suggest that linguistic plays have a significant impact on the improvement of the aforementioned skills in hearing-impaired children.Conclusion: Results suggest that it would be beneficial to include linguistic plays as part of routine rehabilitation programs as a means of improving the grammatical difficulties of children. After partaking in linguistic plays, children significantly improved their ability to comprehend the meaning of sentences and also to recognize, understand, and use common Persian morphological forms.

    Full Text Available Background and Aim: Reading is the most important human need for learning. In normal-hearing people working memory is a predictor of reading comprehension. In this study the relationship between working memory and reading comprehension skills was studied in hearing-impaired children, and then compared with the normal-hearing group.Methods: This was a descriptive-analytic study. The working memory and reading comprehension skills of 18 (8 male, 10 female sever hearing-impaired children in year five of exceptional schools were compared by means of a reading test with 18 hearing children as control group. The subjects in the control group were of the same gender and educational level of the sample group.Results: The children with hearing loss performed similarly to the normal-hearing children in tasks related to auditory-verbal memory of sounds (reverse, visual-verbal memory of letters, and visual-verbal memory of pictures. However, they showed lower levels of performance in reading comprehension (p<0.001. Moreover, no significant relationship was observed between working memory and reading comprehension skills.Conclusion: Findings indicated that children with hearing loss have a significant impairment in the reading comprehension skill. Impairment in language knowledge and vocabulary may be the main cause of poor reading comprehension in these children. In hearing-impaired children working memory is not a strong predictor of reading comprehension.

    Questionnaires evaluating hearing impairment are available in English but there is a need for French standardised questionnaires for researchers as well as for audiologists and other clinicians. The objective of this study is to describe the translation and validation of four questionnaires that assess different aspects of hearing impairment and handicap among elders with hearing loss, by comparing the main score and psychometric evaluation of original and French-Canadian (FC) versions of the World Health Organization Disability Assessment Scale II (WHO-DAS II), the Screening Test for Hearing Problems (STHP), the Abbreviated Profile of Hearing Aid Benefit (APHAB) and the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids (MARS-HA). Vallerand method: translation and back-translation by two translators, revision by a committee of experts and pre-tested with five bilingual older participants. Participants (n = 29) were 65 years of age or older including 21 with hearing aids. The psychometric properties (internal consistency, temporal stability after four weeks) indicate good reliability for most of the translated questionnaires and their subscales, especially the WHO-DAS II. The translations in FC of two hearing loss and two hearing aid questionnaires were validated. It is recommended to pursue the demonstration for temporal stability for the STHP.

    To systematically assess the data on the prevalence and causes of hearing impairment in Africa. Systematic review on the prevalence and causes of hearing loss in Africa. We undertook a literature search of seven electronic databases (EMBASE, PubMed, Medline, Global Health, Web of Knowledge, Academic Search Complete and Africa Wide Information) and manually searched bibliographies of included articles. The search was restricted to population-based studies on hearing impairment in Africa. Data were extracted using a standard protocol. We identified 232 articles and included 28 articles in the final analysis. The most common cut-offs used for hearing impairment were 25 and 30 dB HL, but this ranged between 15 and 40 dB HL. For a cut-off of 25 dB, the median was 7.7% for the children- or school-based studies and 17% for population-based studies. For a cut-off of 30 dB HL, the median was 6.6% for the children or school-based studies and 31% for population-based studies. In schools for the deaf, the most common cause of hearing impairment was cryptogenic deafness (50%) followed by infectious causes (43%). In mainstream schools and general population, the most common cause of hearing impairment was middle ear disease (36%), followed by undetermined causes (35%) and cerumen impaction (24%). There are very few population-based studies available to estimate the prevalence of hearing impairment in Africa. Those studies that are available use different cut-offs, making comparison difficult. However, the evidence suggests that the prevalence of hearing impairment is high and that much of it is avoidable or treatable. © 2015 John Wiley & Sons Ltd.

  15. Incidence of risk factors for hearing impairment in premature babies

    Full Text Available According to the World Health Organization, the incidence of hearing impairment in newborn population is 1-3 per 1000 (WHO, 2012. Apart from that, many authors have found that the incidence of hearing impairment is twenty times higher, 2-4%, in neonatal intensive care unit (NICU. Thus, a congenital hearing loss is the most frequent sensory or motor deficit that could be diagnosed immediately upon birth. The objective of this study was to determine the incidence of risk factors for hearing impairment in the population of preterm babies. We were especially interested in the impact of gestational age at birth on the incidence of risk factors for hearing loss. A cohort of 150 preterm babies was enrolled in the study. They were hospitalized in the Institute for Neonatology in Belgrade during 2014 and 2015 and the data were obtained from their medical files. The results of this study indicate high incidence of risk factors for hearing impairment in this population of babies. Gestational age at birth had a strong, statistically significant, correlation with risk factor incidence in lower gestational age and vice versa. High incidence of risk factors and their interaction could account for twenty times higher occurrence of congenital and early acquired hearing loss in population of preterm babies compared to term neonates. These results imply the need for systematic audiological surveillance of prematurely born babies at least until 12 months of corrected age.

    2015-01-01

    To examine the association of cognitive function, age, and hearing loss with clinically assessed hearing aid benefit in older hearing-impaired persons. Hearing aid benefit was assessed using objective measures regarding speech recognition in quiet and noisy environments as well as a subjective measure reflecting everyday situations captured using a standardized questionnaire. A broad range of general cognitive functions such as attention, memory, and intelligence were determined using different neuropsychological tests. Linear regression analyses were conducted with the outcome of the neuropsychological tests as well as age and hearing loss as independent variables and the benefit measures as dependent variables. Thirty experienced older hearing aid users with typical age-related hearing impairment participated. Most of the benefit measures revealed that the participants obtained significant improvement with their hearing aids. Regression models showed a significant relationship between a fluid intelligence measure and objective hearing aid benefit. When individual hearing thresholds were considered as an additional independent variable, hearing loss was the only significant contributor to the benefit models. Lower cognitive capacity - as determined by the fluid intelligence measure - was significantly associated with greater hearing loss. Subjective benefit could not be predicted by any of the variables considered. The present study does not give evidence that hearing aid benefit is critically associated with cognitive function in experienced hearing aid users. However, it was found that lower fluid intelligence scores were related to higher hearing thresholds. Since greater hearing loss was associated with a greater objective benefit, these results strongly support the advice of using hearing aids regardless of age and cognitive function to counter hearing loss and the adverse effects of age-related hearing impairment. Still, individual cognitive capacity might

    The current paper estimates the prevalence of hearing problems in a rural population, analyzes the prevalence of hearing problems across age groups, and compares the prevalence of hearing problems in this population with results obtained in other populations. Data were obtained from a random sample of the residents of a rural county, stratified by farm, rural non-farm, and town residence. Hearing test results were obtained from participants between the ages of 8 and 92 years (N = 1972; 47% male). Pure-tone thresholds were classified as normal or impaired using a number of metrics, including speech intelligibility index values. Selected comparisons of crude rates were made with previous population-based studies of hearing loss prevalence. Nearly all (99%) of the participants in this study had significant hearing impairment. Atypical hearing impairment is most prevalent at 6 kHz. In males, this excess impairment shifts to lower frequencies with age but monotonically decreases in females. Notched configurations were most common among those between 30 and 59 years old. In females, the prevalence of hearing impairments sufficient to interfere with speech understanding begins to rapidly increase in the 6th decade (4th decade in males). Comparisons with prior population-based studies in the United States and Great Britain identified few significant differences. Significant hearing impairment is common in rural populations. The high prevalence in this population is similar to that found in other population-based studies. Future studies are needed to examine (1) the risk factors for hearing impairment, (2) the natural course of hearing problems across the life span, and (3) the effect of programs for the prevention of hearing impairment and rehabilitation for persons with existing hearing impairments.

    Hearing impairment may affect the body posture maintenance. The aim of the study was to evaluate the effect of modified Pilates exercise program on the body posture maintenance in hearing impaired people. Eighty students (aged 13-24) were enrolled and randomly allocated into two groups: test group (n = 41) which attended an original program based on modified Pilates exercises and control group (n = 39) which attended standard physical education classes. Stabilographic tests were conducted at baseline and after 6-week training program. Both groups showed improved control of body balance in a standing position manifested in reductions of the length of path, surface area, and speed of deflection. Modified Pilates program was significantly more effective in improving body balance control in relaxed posture and with feet together than standard physical education classes. The greater efficiency of the modified Pilates program was expressed in a significant improvement in balance control parameters, i.e., path length, surface area, and speed of deflection. The modified Pilates program was more effective in improving body balance control in the hearing impaired people than standard physical education classes. Modification of physical activity recommendations for hearing impaired students may be considered; however, further research is required. Implications for Rehabilitation Hearing impairment impacts the mental, social and, physical spheres of life as well as deteriorates equivalent reactions and the way body posture is maintained. In hearing impaired people, control of body balance and muscle coordination is often disturbed, thus more attention should be paid to exercises associated with balance which may improve the ability to learn and develop motor skills. Modified Pilates program was significantly more effective in improving body balance control than standard physical education classes in hearing impaired people.

  1. Communication between hearing impaired and normal hearing students: a facilitative proposal of learning in higher education

    2014-09-01

    Full Text Available Introduction: There has been an increase in the number of hearing impaired people with access to higher education. Most of them are young people from a different culture who present difficulties in communication, inter-relationship, and learning in a culture of normal hearing people, because they use a different language, the Brazilian Sign Language - LIBRAS. Objective: The present study aimed to identify the forms of communication used between hearing impaired and normal hearing students, verifying how they can interfere with the learning process of the first. Methods: A qualitative study that used the space of a private university in the city of Fortaleza, Ceará state, Brazil, from February to April 2009. We carried out semi-structured interviews with three hearing impaired students, three teachers, three interpreters, and three normal hearing students. The content of the speeches was categorized and organized by the method of thematic analysis. Results: We verified that the forms of communication used ranged from mime and gestures to writing and drawing, but the most accepted by the hearing impaired students was LIBRAS. As a method of communication, it supports the learning of hearing impaired students, and with the mediation of interpreters, it gives them conditions to settle in their zones of development, according to the precepts of Vygotsky. Conclusion: Thus, we recognize the importance of LIBRAS as predominant language, essential to the full academic achievement of hearing impaired students; however, their efforts and dedication, as well as the interest of institutions and teachers on the deaf culture, are also important for preparing future professionals.

    The aims of this study were to investigate the effects of either hearing, vision or dual sensory impairment on depressive symptoms and to identify subgroups that are vulnerable and significantly affected. Data from the 2006-2014 Korean Longitudinal Study of Aging (KLoSA) were used and a total of 5832 individuals were included in this study. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D10) scale. Sensory impairment was assessed according to the levels of self-reported hearing or vision, which were categorised as either good (excellent, very good or good) or poor (fair or poor). The changes in hearing or vision from records of previous survey were investigated. Changes from good to poor, which indicates new onset, were defined as hearing impairment or vision impairment. Interactions of changes in hearing and vision were considered in the analysis. Dual sensory impairment was indicated when hearing impairment and vision impairment both developed at the same time. Demographic, socioeconomic and health-related factors were considered as potential confounders and were adjusted for in the generalised estimating equation model. Individuals with hearing impairment demonstrated significantly more severe depressive symptoms [β = 0.434, standard errors (s.e.) = 0.097, p impairment also showed significantly elevated depressive symptoms (β = 0.253, s.e. = 0.058, p impairment showed significantly more severe depressive symptoms (β = 0.768, s.e. = 0.197, p impairment on depressive symptoms was significant in both sexes and across age groups, except for vision impairment in male participants. Hearing, vision and dual sensory impairment are significantly associated with depressive symptoms. Our results suggest that treatment or rehabilitation of either hearing or vision impairment would help prevent depression.

  4. What factors influence help-seeking for hearing impairment and hearing aid adoption in older adults?

    Meyer, Carly; Hickson, Louise

    2012-02-01

    The purpose of this review paper was to identify factors that influence older adults' decisions to seek help for hearing impairment and to adopt hearing aids. A literature search of abstracts within peer-reviewed journal articles published in English between 1990 and 2010 was conducted in online bibliographic databases using the keywords: hearing; impair* or loss; seek* or candidate* or applicant* or acquir*; and hearing aid* or help or advice. Twenty-two articles that were directly relevant to this topic were included in this review. The evidence suggests that individuals are more likely to seek help for hearing impairment and/or adopt hearing aids if they: (1) have a moderate to severe hearing impairment and self-reported hearing-related activity limitations or participation restrictions; (2) are older; (3) perceive their hearing as poor; (4) consider there to be more benefits than barriers to amplification; and (5) perceive their significant other/s as supportive of hearing rehabilitation. A barrier to help-seeking for hearing impairment and hearing aid adoption appears to be general practitioners' management of age-related hearing impairment.

    Full Text Available Background and Aim: Stress is the source of many problems in human-kind lives and threatens people's life constantly. Having hearing-impaired child, not only causes stress in parents, but also affects their marital satisfaction. The purpose of this study was comparing the stress and marital satisfaction status between the normal and hearing-impaired children's parents.Methods: This was a causal-comparative study. Eighty parents of normal children and 80 parents of hearing-impaired children were chosen from rehabilitation centers and kindergartens in city of Tabriz, Iran by available and clustering sampling method. All parents were asked to complete the Friedrich's source of stress and Enrich marital satisfaction questionnaires.Results: Parents of hearing-impaired children endure more stress than the normal hearing ones (p<0.001. The marital satisfaction of hearing-impaired children's parents was lower than the parents of normal hearing children, too (p<0.001.Conclusion: Having a hearing-impaired child causes stress and threatens the levels of marital satisfaction. This requires much more attention and a distinct planning for parents of handicap children to reduce their stress.

    Hearing impairment is a recognized cause of emotional and psychological disturbances worldwide, however little is known about this condition in Nigeria. The aim of this study is to compare the prevalence of psychopathology between hearing impaired adolescents and healthy adolescents. Students attending two special schools for the hearing impaired were assessed for psychopathology with the help of a trained signer and their teacher, using the International Classification of Diseases Diagnostic Criteria (ICD 10). Fifty two hearing impaired students and 52 age and sex matched controls from the same school were also interviewed using the same instrument. The mean age of the hearing impaired students was 16 (sd=3.8), while for the controls the mean age was 16 (sd=2.5). Psychopathology was present in 10 (19%) of the hearing impaired adolescents compared to 2 (4%) among the control group, this difference was statistically significant (χ(2)=4.62 p=0.03). The most common diagnosis was generalized anxiety disorder 4 (8%), followed by depression 2 (4%). Years spent in school (t=4.81, p=0.001), primary guardian (χ(2)=18.3, p=0.001) and mean income of guardian (t=7.10, p=0.001) were all significantly different between the two groups. Psychopathology is relatively common in this population. Proper assessment and treatment should be made available for this population group. A limitation to this study is communication difficulty which made only a third party assessment possible; this may affect the generalizability of the findings. Copyright © 2015 Elsevier B.V.

    2014-12-01

    The Vibrant Soundbridge is the world's most often implanted active middle ear implant or hearing aid. During the last few years, the device indications have expanded from sensorineural hearing loss to conductive and mixed hearing loss. Titanium couplers have led to improved contact of the floating mass transducer with the middle ear structures. The resulting hearing gain is satisfying for most patients, but so far, there is no clear audiologic advantage over conventional hearing aids. Currently, the indications are mainly related to intolerance of conventional hearing aids (eg, chronic otitis externa), severe mixed hearing loss with a destructed middle ear and certain medical diagnosis (eg, congenital atresia).

    Desjardins, Jamie L; Doherty, Karen A

    2014-01-01

    The purpose of the present study was to evaluate the effect of a noise-reduction (NR) algorithm on the listening effort hearing-impaired participants expend on a speech in noise task. Twelve hearing-impaired listeners fitted with behind-the-ear hearing aids with a fast-acting modulation-based NR algorithm participated in this study. A dual-task paradigm was used to measure listening effort with and without the NR enabled in the hearing aid. The primary task was a sentence-in-noise task presented at fixed overall speech performance levels of 76% (moderate listening condition) and 50% (difficult listening condition) correct performance, and the secondary task was a visual-tracking test. Participants also completed measures of working memory (Reading Span test), and processing speed (Digit Symbol Substitution Test) ability. Participants' speech recognition in noise scores did not significantly change with the NR algorithm activated in the hearing aid in either listening condition. The NR algorithm significantly decreased listening effort, but only in the more difficult listening condition. Last, there was a tendency for participants with faster processing speeds to expend less listening effort with the NR algorithm when listening to speech in background noise in the difficult listening condition. The NR algorithm reduced the listening effort adults with hearing loss must expend to understand speech in noise.

    2015-07-01

    Full Text Available Understanding underlying pathological mechanisms is prerequisite for a sensible design of protective therapies against hearing loss. The triad of age-related, noise-generated, and drug-induced hearing loss ¬¬displays intriguing similarities in some cellular responses of cochlear sensory cells such as a potential involvement of reactive oxygen species and apoptotic and necrotic cell death. On the other hand, detailed studies have revealed that molecular pathways are considerably complex and, importantly, it has become clear that pharmacological protection successful against one form of hearing loss will not necessarily protect against another. This review will summarize pathological and pathophysiological features of age-related hearing impairment (ARHI in human and animal models and address selected aspects of the commonality (or lack thereof of cellular responses in ARHI to drugs and noise.

    Ira Hirsh's contributions to clinical science and research are diverse and significant. In fact, approximately one-third of the 100+ publications that Ira lists in his curriculum vitae (CV) are clinical in nature, dealing with various aspects of audiology, deafness, hearing aids, aural rehabilitation, and speech and language pathology. The majority of these citations, fully one-quarter of his publication list, addresses problems specific to the clinical measurement of hearing and hearing impairment. Undoubtedly, the most influential of these published works appears in his CV under the citation ``The Measurement of Hearing.'' The forward for this publication, his only textbook, was penned in June, 1952 (now precisely half a century past at the time of this session). The aims of this presentation are to (1) provide perspective on the fundamental importance of his virtually timeless text in shaping the fledgling discipline of audiology, and (2) celebrate Ira's many contributions to the profession and practice of audiology.

    In elementary school classes, noise during student led activities is often taken as evidence of successful interaction and learning. In this complex social environment of elementary school classrooms, acquisition of complex language and social skills-the focus of activities in early education-is expected to take place in hearing-hostile environments. Communication and language processing in these contexts requires interactive strategies, discourse forms, and syntactic structures different from the educationally desired forms used in acoustically advantageous environments. Recordings were made of the interaction of groups of students in grades 1-3, 5, and 7 during collaborative group work in their regular classrooms. Each student wore microphones at the ear level and head-mounted video cameras. Each group as a whole was also audio- and videotaped and noise level readings were recorded. Analysis of the acoustical and phonological properties of language heard by each student has demonstrated that the language variety used in these noisy and reverberant settings is similar to that of individuals with hearing impairments. This paper reports similarities between the syntactic structures and pragmatic strategies used by hearing impaired children and normally hearing children in noisy contexts.

    Gigiane Gindri

    Full Text Available ABSTRACT Language impairments in patients with acquired brain injury can have a negative impact on social life as well as on other cognitive domains. Discourse impairments are among the most commonly reported communication deficits among patients with acquired brain damage. Despite advances in the development of diagnostic tools for detecting such impairments, few studies have investigated interventions to rehabilitate patients presenting with these conditions. Objective: The aim of this study was to present a systematic review of the methods used in the rehabilitation of discourse following acquired brain injury. Methods: The PubMed database was searched for articles using the following keywords: "rehabilitation", "neurological injury", "communication" and "discursive abilities". Results: A total of 162 abstracts were found, but only seven of these met criteria for inclusion in the review. Four studies involved samples of individuals with aphasia whereas three studies recruited samples of individuals with traumatic brain injury. Conclusion: All but one article found that patient performance improved following participation in a discourse rehabilitation program.

    Full Text Available The aim of this study was to explore the structure and the correlates of students attitudes towards persons with hearing impairments. The sample consisted of 103 first year students of The Faculty of Special Education and Rehabilitation (F-93; M-10, divisions Prevention and treatment of conduct disorders and Speech therapy. These attitudes were assessed by The revised version of Multidimensional Attitudes Scale Toward Persons With Disabilities, Empathy by Empathy Quotient, dimensions of personality by The Big Five Inventory, the attachment by Experiences in Close Relationships Scale, the motivation for studying the Faculty of Special Education and Rehabilitation by the scale assembled for this research. It was found that in the domain of basic dimensions of personality only tendency to collaborate with others negatively correlates with absence of pro-social thoughts (-0.204, scale of anxiety in close relationships, in attachment domain, positively correlates with inhibiting thoughts and feelings (0.220, while the empathy quotient negatively correlates with the absence of pro-social thoughts (-0.226. The motivation for studying Faculty of Special Education and Rehabilitation was not associated with components of the attitude towards people with hearing impairment. Future researches should try to identify predictors of negative emotional and behavioral which lead to ignoring and rejecting of persons with disability.

    2009-01-01

    Binaural pitch is a tonal sensation produced by introducing a frequency-dependent interaural phase shift in binaurally presented white noise. As no spectral cues are present in the physical stimulus, binaural pitch perception is assumed to rely on accurate temporal fine structure coding and intact...... binaural integration mechanisms. This study investigated to what extent basic auditory measures of binaural processing as well as cognitive abilities are correlated with the ability of hearing-impaired listeners to perceive binaural pitch. Subjects from three groups (1: normal-hearing; 2: cochlear...... hearingloss; 3: retro-cochlear impairment) were asked to identify the pitch contour of series of five notes of equal duration, ranging from 523 to 784 Hz, played either with Huggins’ binaural pitch stimuli (BP) or perceptually similar, but monaurally detectable, pitches (MP). All subjects from groups 1 and 2...

    Full Text Available This study describes the communicative performance of a severely hearing-impaired adolescent.The experimenter taught the subject how to play Russian Backgammon. The subject conversed with, and afterwards taught his mother, speech therapist, and a peer how to play the game. Each dyad played the game once. Videotape recordings were made of each dyadic situation. The channels of communication, both verbal and nonverbal, used by each speaker, were determined. A relational communication coding scheme, involving the analysis of requests and subsequent responses, was applied to the data. Results indicate that the hearing-impaired adolescent, though not always able to hold a dominant position in a dyadic situation, was capable of expressing the same types of control as normal adults. Moreover, the types of control expressed varied as a function of each contextual setting. Whenever the subject did hold a dominant position, the combined verbal plus nonverbal channel was his predominant mode of  communication. These findings  suggest that a sociolinguistic approach provides important information regarding a hearing-impaired adolescent's communicative performance.

    Spatial hearing refers to the ability to understand speech and identify sounds in various environments. We assessed the validity of the Korean version of the Spatial Hearing Questionnaire (K-SHQ). We performed forward translation of the original English SHQ to Korean and backward translation from the Korean to English. Forty-eight patients who were able to read and understand Korean and received a score of 24 or higher on the Mini-Mental Status Examination were included in the study. Patients underwent pure tone audiometry (PTA) using a standard protocol and completed the K-SHQ. Internal consistency was evaluated using Cronbach's alpha, and factor analysis was performed to prove reliability. Construct validity was tested by comparing K-SHQ scores from patients with normal hearing to those with hearing impairment. Scores were compared between subjects with unilateral or bilateral hearing loss and between symmetrical and asymmetrical hearing impairment. Cronbach's alpha showed good internal consistency (0.982). Two factors were identified by factor analysis: There was a significant difference in K-SHQ scores for patients with normal hearing compared to those with hearing impairment. Patients with asymmetric hearing impairment had higher K-SHQ scores than those with symmetric hearing impairment. This is related to a lower threshold of PTA in the better ear of subjects. The hearing ability of the better ear is correlated with K-SHQ score. The K-SHQ is a reliable and valid tool with which to assess spatial hearing in patients who speak and read Korean. K-SHQ score reflects the severity and symmetry of hearing impairment. © Copyright: Yonsei University College of Medicine 2017

    To undertake a systematic review of available evidence on the effect of hearing impairment and hearing aid amplification on listening effort. Two research questions were addressed: Q1) does hearing impairment affect listening effort? and Q2) can hearing aid amplification affect listening effort during speech comprehension? English language articles were identified through systematic searches in PubMed, EMBASE, Cinahl, the Cochrane Library, and PsycINFO from inception to August 2014. References of eligible studies were checked. The Population, Intervention, Control, Outcomes, and Study design strategy was used to create inclusion criteria for relevance. It was not feasible to apply a meta-analysis of the results from comparable studies. For the articles identified as relevant, a quality rating, based on the 2011 Grading of Recommendations Assessment, Development, and Evaluation Working Group guidelines, was carried out to judge the reliability and confidence of the estimated effects. The primary search produced 7017 unique hits using the keywords: hearing aids OR hearing impairment AND listening effort OR perceptual effort OR ease of listening. Of these, 41 articles fulfilled the Population, Intervention, Control, Outcomes, and Study design selection criteria of: experimental work on hearing impairment OR hearing aid technologies AND listening effort OR fatigue during speech perception. The methods applied in those articles were categorized into subjective, behavioral, and physiological assessment of listening effort. For each study, the statistical analysis addressing research question Q1 and/or Q2 was extracted. In seven articles more than one measure of listening effort was provided. Evidence relating to Q1 was provided by 21 articles that reported 41 relevant findings. Evidence relating to Q2 was provided by 27 articles that reported 56 relevant findings. The quality of evidence on both research questions (Q1 and Q2) was very low, according to the Grading of

    The latest international guidelines highlight the importance of involving the family in the diagnostic and rehabilitation process of children affected by permanent hearing impairment. This emphasises how meaningful this approach is for the development of the deaf child. So far, there is very little evidence about this approach in Italy, and there are still some barriers to its practical management. The aim of this paper is to report the results of a strategic analysis, which identifies the strengths, weaknesses, opportunities and threats of the family empowerment process during early auditory diagnosis and rehabilitation. The audiology programme should have the goal to offer information and support to families in order to achieve a conscious decision about the use and type of auditory prosthesis and rehabilitation choice within three months after audiologic diagnosis. Within the framework of the Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for Early Identification, Intervention and Care of Hearing Impaired Children", a group of professionals identified three main recommendations that can be useful to foster the natural communicative development of the child by strengthening the therapeutic alliance and empowerment of the family. The recommendations obtained with this analysis can help to develop new Italian guidelines with the aim to foster natural communicative development of the child by strengthening the therapeutic alliance and empowerment of the family. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale.

    Audiologic rehabilitation of individuals with profound unilateral sensorineural hearing loss (USNHL) has traditionally been limited to the use of air-conduction contralateral routing of sound (CROS) hearing aids. Treatment for these individuals has expanded with new applications of the bone-anchored hearing aid (BAHA), transcranial hearing aid (t-CROS), and the cochlear implant. In this article, the authors review the literature that addresses these various treatment options. Contemporary review Historical information is available that describes the limited efficacy of air-conduction CROS hearing aids in lifting hearing handicap associated with USNHL. Current investigations on providing cross hearing are generally focused on use of the BAHA. Little is known at present whether new developments in hearing aid technology can improve on conventional air-conduction CROS or t-CROS approaches. Interestingly, the cochlear implant seems to be a viable option for individuals with USNHL and tinnitus who also have intact auditory nerve pathways. There is indication in the literature that BAHA provides greater relief of hearing handicap associated with USNHL than CROS hearing aids; however, both have been found to provide limited patient satisfaction and seemingly fall short of restoring true sound localization. Adequate trials have not been performed comparing BAHA with the best CROS hearing aid technology. Transcranial hearing aids and cochlear implants are experimental methods to treat USNHL and hold promise, although there remains a lack of studies available to fully support this.

    The purpose of this study was to investigate the effect of symmetrical, asymmetrical and unilateral hearing impairment on music quality perception. Six validated music pieces in the categories of classical music, folk music and pop music were used to assess music quality in terms of its 'pleasantness', 'naturalness', 'fullness', 'roughness' and 'sharpness'. 58 participants with sensorineural hearing loss [20 with unilateral hearing loss (UHL), 20 with bilateral symmetrical hearing loss (BSHL) and 18 with bilateral asymmetrical hearing loss (BAHL)] and 29 normal hearing (NH) subjects participated in the present study. Hearing impaired (HI) participants had greater difficulty in overall music quality perception than NH participants. Participants with BSHL rated music pleasantness and naturalness to be higher than participants with BAHL. Moreover, the hearing thresholds of the better ears from BSHL and BAHL participants as well as the hearing thresholds of the worse ears from BSHL participants were negatively correlated to the pleasantness and naturalness perception. HI participants rated the familiar music pieces higher than unfamiliar music pieces in the three music categories. Music quality perception in participants with hearing impairment appeared to be affected by symmetry of hearing loss, degree of hearing loss and music familiarity when they were assessed using the music quality rating test (MQRT). This indicates that binaural symmetrical hearing is important to achieve a high level of music quality perception in HI listeners. This emphasizes the importance of provision of bilateral hearing assistive devices for people with asymmetrical hearing impairment.

    The study reported here explored a partial explanation for the fourth-grade "bottleneck" in literacy advancement by hearing-impaired students. Speech samples from 21 deaf subjects were rated for degree of evident phrasal quality. Likewise, reading comprehension scores for each student were obtained under four reading conditions: reading in whole sentences, in phrases, in fragmented word groups, and in single words. Degree of rated speech phrasality was found to relate significantly and positively to correct recall answers to questions based upon silent reading of passages typed in meaningful word groups (but not when the passages were typed in whole sentences, fragmented word groups, or in single words). The results were taken to suggest that--whereas staccato-speaking deaf students may lack a sense of the phrase altogether--phrasal-speaking deaf youngsters fail to independently apply their phrase sense in the normal reading situation. Thus, both types of deaf youngsters have difficulty affecting the transition to phrase reading that is common for hearing students at or about the fourth-grade level. Finally, I argue that this phrase sense can be instilled in hearing-impaired students and that they can be trained to use it in reading.

    This study aimed at analyzing the association between the lexical development of children with hearing impairment and their psychosocial and socioeconomic characteristics and medical history. An analytic transversal study was conducted in an Auditive Health Attention Service. One hundred and ten children from 6 to 10 years old using hearing aids and presenting hearing loss that ranged from light to deep levels were evaluated. All children were subjected to oral, written language and auditory perception tests. Parents answered a structured questionnaire to collect data from their medical history and socioeconomic status, and questionnaires about the features of the family environment and psychosocial characteristics. Multivariate analysis was performed by logistic regression, being the initial model composed by variables with panalysis. In the final model, we adopted a significance level of 5%. The final model of the multivariate analysis showed an association between the performance on the vocabulary test and the results of phonemic discrimination test (OR=0.81; 95%CI 0.73-0.89). The results show the importance of stimulating the auditory processing, particularly the phonemic discrimination skill, throughout the rehabilitation process of children with hearing impairment. This stimulation can enhance lexical development and minimize the metalanguage and learning difficulties often observed in these children.

    Diagnosis of child permanent hearing impairment (PHI) can be made with extreme timeliness compared to the past thanks to improvements in PHI identification through newborn hearing screening programmes. It now becomes essential to provide an effective amplification as quickly as possible in order to restore auditory function and favour speech and language development. The early fitting of hearing aids and possible later cochlear implantation indeed prompts the development of central auditory pathways, connections with secondary sensory brain areas, as well as with motor and articulatory cortex. The aim of this paper is to report the results of a strategic analysis that involves identification of strengths, weaknesses, opportunities and threats regarding the process of achieving early amplification in all cases of significant childhood PHI. The analysis is focused on the Italian situation and is part of the Italian Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for Early Identification, Intervention and Care of Hearing Impaired Children". © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale.

    Sensory impairment affects an increasing number of elderly adults, with a negative psychological impact. Our objective was to examine the associations of visual and hearing impairment with subjective well-being (SWB), an important psychological concept defined by life satisfaction [LS], positive affect [PA], negative affect [NA], and affect balance [AB] among long-lived individuals (LLIs) over 95 years of age. Data on 442 LLIs from the Rugao longevity cohort, a population-based study in Rugao, China, were analyzed. Graded classifications of visual and hearing impairment (none, mild, moderate, and severe) were constructed from self-reported items. Bivariate correlation and multiple regression analysis were performed to test the associations. Approximately 66.1% and 87.3% of the subjects reported varying degrees of visual and hearing impairment. Following the degree of vision impairment, LS, PA, and AB decreased linearly, whereas NA increased linearly (all p for trendimpairment with LS, NA, and AB, while diminished, still existed. Visual impairment, but not hearing impairment, was independently associated with low SWB among LLIs, and functional ability may play a mediating role in the observed relationship. The findings indicate that rehabilitation targeted for those with reduced vision and functioning in long-lived populations may be important for promoting well-being and quality of life.

    Early diagnosis of hearing impairment is of crucial importance in a child’s life. For this reason, a pediatrician should perform a hearing exam, along with other necessary specialised tests, immediately after he/she had identified risks of hearing impairment in the newborn‘s anamnesis or had ben warned by the parents about a possible problem. Both the diagnosis of congenital or acquired hearing impairment after birth, and the installment of hearing aids, should take place by the end of the first year in a child’s life at the latest.

    Full Text Available Background: Hearing impairment has a devastating, detrimental and an invariably adverse impact on the development of the newborns and the psychological well-being of their families. It also adversely affects development of the central auditory nervous system, and can affect speech perception that interferes with growth in social, emotional, behavioural and cognitive spheres, academic achievement, vocational options, employment opportunities and economic selfsufficiency. Objectives: To find out incidence of hearing impairment in high risk neonates in Neonatal Intensive Care Unit (NICU, prevalence of hearing impairment with and without high risk factors in newborns and to correlate the risk factors with hearing impairment. Material and Methods: A cohort study was carried out at a tertiary care hospital of Surat, Gujarat, India consisting of 190 normal newborns and 163 newborns with high risk factors. These newborns underwent a systematized Transient Otoacoustic Emissions Examination (TOAE and Brain Stem Evoked Audiometry (BERA examination according to designed protocol and were followed up with repeated ear examinations. Data were recorded and analyzed statistically. Results: The incidence of hearing impairment in NICU, newborns were 3.6% and the prevalence of hearing impairment was 13%. Hearing impairment was statistically significant in newborns with high risk factors such as low birth weight, preterms 5 days when compared to normal newborns. Conclusion: Presence of risk factors in newborns predisposes them to hearing impairment more as compared to normal newborns and the more the number of risk factors they are exposed to, the more will be the chances of hearing impairment.

    To compare the effect of rehabilitation of prelingual deaf children who used a cochlear implant (CI) in one ear and a hearing aids in the opposite ear while the hearing level of the opposite ears are different. Hearing ability, language ability and learning ability was included in the content. The aim of this research is to investigate better style of rehabilitation, and to offer the best help to the prelingual deaf children. Accord ing to the hearing level of the ear opposite to the one wearing a cochlear implant and whether the opposite ear wear a hearing aid or not, 30 prelingual deaf children were divided into three groups, including cochlear implant with opposite severe hearing loss and hearing aid ear (CI+SHA), cochlear implant with opposite profound hearing loss and hearing aid ear (CI+PHA), cochlear implant only (CI). The effect of rehabilitation was assessed in six different times (3,6,9,12,15 and 18 months after the cochlear implants and hearing aids began to work). The longer time the rehabilitation spends, the better the hearing ability,language ability and the learning ability were. The hearing ability of CI+SHA was better than those of CI+PHA (Pdeaf children should take much more time on rehabilitation. The effect of rehabilitation for prelingual deaf children who used cochlear implant in one ear and hearing aid in the other depend on the residual hearing level of the other ear. If a prelingual deaf children still has any residual hearing level in the ear opposite to the cochlear implant ear, it is better for him/her to wear a hearing aid in the ear.

    There is converging evidence for altered audiovisual integration abilities in hearing-impaired individuals and those with profound hearing loss who are provided with cochlear implants, compared to normal-hearing adults. Still, little is known on the effects of hearing aid use on audiovisual integration in mild hearing loss, although this constitutes one of the most prevalent conditions in the elderly and, yet, often remains untreated in its early stages. This study investigated differences in the strength of audiovisual integration between elderly hearing aid users and those with the same degree of mild hearing loss who were not using hearing aids, the non-users, by measuring their susceptibility to the sound-induced flash illusion. We also explored the corresponding window of integration by varying the stimulus onset asynchronies. To examine general group differences that are not attributable to specific hearing aid settings but rather reflect overall changes associated with habitual hearing aid use, the group of hearing aid users was tested unaided while individually controlling for audibility. We found greater audiovisual integration together with a wider window of integration in hearing aid users compared to their age-matched untreated peers. Signal detection analyses indicate that a change in perceptual sensitivity as well as in bias may underlie the observed effects. Our results and comparisons with other studies in normal-hearing older adults suggest that both mild hearing impairment and hearing aid use seem to affect audiovisual integration, possibly in the sense that hearing aid use may reverse the effects of hearing loss on audiovisual integration. We suggest that these findings may be particularly important for auditory rehabilitation and call for a longitudinal study.

    There is no doubt that gestures are communicative and can be integrated online with speech. Little is known, however, about the nature of this process, for example, its automaticity and how our own communicative abilities and also our environment influence the integration of gesture and speech. In two Event Related Potential (ERP) experiments, the effects of gestures during speech comprehension were explored. In both experiments, participants performed a shallow task thereby avoiding explicit gesture-speech integration. In the first experiment, participants with normal hearing viewed videos in which a gesturing actress uttered sentences which were either embedded in multi-speaker babble noise or not. The sentences contained a homonym which was disambiguated by the information in a gesture, which was presented asynchronous to speech (1000 msec earlier). Downstream, the sentence contained a target word that was either related to the dominant or subordinate meaning of the homonym and was used to indicate the success of the disambiguation. Both the homonym and the target word position showed clear ERP evidence of gesture-speech integration and disambiguation only under babble noise. Thus, during noise, gestures were taken into account as an important communicative cue. In Experiment 2, the same asynchronous stimuli were presented to a group of hearing-impaired students and age-matched controls. Only the hearing-impaired individuals showed significant speech-gesture integration and successful disambiguation at the target word. The age-matched controls did not show any effect. Thus, individuals who chronically experience suboptimal communicative situations in daily life automatically take gestures into account. The data from both experiments indicate that gestures are beneficial in countering difficult communication conditions independent of whether the difficulties are due to external (babble noise) or internal (hearing impairment) factors.

    Following current prognosis, demographic development raises expectations of an aging of the working population. Therefore, keeping employees healthy and strengthening their ability to work, becomes more and more important. When employees become older, dealing with age-related impairments of sensory functions, such as hearing impairment, is a central issue. Recent evidence suggests that negative effects that are associated with reduced hearing can have a strong impact at work. Especially under exhausting working situations such as working overtime hours, age and hearing impairment might influence employees' well-being. Until now, neither the problem of aged workers and long working hours, nor the problem of hearing impairment and prolonged working time has been addressed explicitly. Therefore, a laboratory study was examined to answer the research question: Do age and hearing impairment have an impact on psychophysiological and subjective effects of long working hours. In total, 51 white-collar workers, aged between 24 and 63 years, participated in the laboratory study. The results show no significant effects for age and hearing impairment on the intensity of subjective consequences (perceived recovery and fatigue, subjective emotional well-being and physical symptoms) of long working hours. However, the psychophysiological response (the saliva cortisol level) to long working hours differs significantly between hearing impaired and normal hearing employees. Interestingly, the results suggest that from a psychophysiological point of view long working hours were more demanding for normal hearing employees.

    The number of deaf children has dramatically increased in the past few decades. These children present to the pediatric dentist a unique set of challenges mostly pertaining to the establishment of communication with them. There have been very few attempts in the past to break down these challenges and formulate a strategy on how to manage them effectively. This is a case report of a child who was successfully managed using two different modes of communication. Finally, the advantages and disadvantages are mentioned, and a common strategy incorporating the positives of both the methods has been devised. Renahan N, Varma RB, Kumaran P, Xavier AM.

    The Newborn Hearing Screening Programme (NHSP) was established in Cork University Maternity Hospital (CUMH) in April 2011. Between April 2011 and July 2014, 42 infants were identified with a Permanent Childhood Hearing Impairment (PCHI). Following this diagnosis, infants underwent a paediatric assessment according to recognised guidelines with the intention of identifying the underlying aetiology of the PCHI. The aim of this study was to assess the findings of this aetiological workup via retrospective chart review. PCHI data was obtained from the eSP database. This is a web based information system (eSP) used to track each baby through the screening and referral process A retrospective chart review of these patients was performed. Sixteen (38%) infants were diagnosed with a bilateral sensorineural hearing loss. Two infants had congenital CMV infection. A Connexin 26 gene mutation was detected in one infant. Two infants were diagnosed with Waardenburg syndrome, One with Pendred syndrome and one with Pfeiffer syndrome. Five babies underwent cochlear implantation. Through adherence to the recommended protocol a possible cause of PCHI may be determined. This study has identified areas of future improvement for this service in Ireland.

    For some patients, genetic testing can reveal the etiology of their hearing impairment, and can provide evidence for a medical diagnosis. However, a gap between fundamental genetic research on hereditary deafness and clinical otology emerges because of the steadily increasing number of discovered genes for hereditary hearing impairment (HHI) and the comparably low clinical differentiation of the HHIs. In an attempt to keep up with the scientific progress, this article enumerates the indications of genetic testing for HHI from a clinical point of view and describes the most frequently encountered HHIs in Belgium. Domains of recent scientific interest, molecular biological aspects, and some pitfalls with HHIs are highlighted. The overview comprises bilateral congenital hearing loss, late-onset progressive high frequency hearing loss, progressive bilateral cochleo-vestibular deficit, and progressive low frequency hearing loss. Also, several syndromal forms of HHI are summarized, and the availability of genetic tests mentioned. Finally, the requirements for successful linkage analysis, an important genetic research tool for localizing the potential genes of a trait on a chromosome, are briefly described.

    This study investigated the Cantonese tone production ability of children with hearing impairment studying in mainstream schools. The participants were 87 Cantonese-speaking children with mild-to-profound degrees of hearing loss aged 5.92-13.58 in Hong Kong. Most of the children were fitted with hearing aids (n = 65); 17 of them had profound hearing impairment, one who had severe hearing loss had cochlear implantation, and four who had mild hearing loss were without any hearing device. The Hong Kong Cantonese Articulation Test was administered, and the tones produced were rated by two of the authors and a speech-language pathologist. Group effects of tones, hearing loss level, and also an interaction of the two were found to be significant. The children with profound hearing impairment performed significantly worse than most of the other children. Tone 1 was produced most accurately, whereas tone 6 productions were the poorest. No relationship was found between the number of years of mainstreaming and tone production ability. Tone production error pattern revealed that confusion patterns in tone perception coincided with those in production. Tones having a similar fundamental frequency (F0) at the onset also posed difficulty in tone production for children with hearing impairment.

    Full Text Available Noisy and vibrating bajaj, a public transportation in Jakarta, is a potential risk in inducing hearing and balance problems. Bajaj drivers in the Jakarta area were chosen by consecutive sampling and examined medically in the Neurotological Subdivision of the ENT Department of the Cipto Mangunkusumo Hospital, Jakarta. Hearing and balance impairments were then diagnosed from audiometric and posturographic tests. The study was carried out from March 2000 until October 2001. A number of 350 bajaj drivers participated in this study. There were 97 subjects without hearing and balance impairments, and 96 subjects suffered from hearing and balance impairments. Compared to drivers aged less than 40 years, those aged 41 years or more had a four-fold increased risk of developing hearing and balance impairments [adjusted odds ratio (OR = 3.90; 95% confidence interval (CI = 1.67-9.01. Drivers working 9 hours or more a day had an increased risk 2.3 times of developing hearing and balance impairments compared those working less than 9 hours a day (adjusted OR = 2.32; 95% CI=I.22-4.41. Furthermore, when compared to those who had been working for 1-5 years, those who had been working for 5 years had an increased tendency of developing hearing and balance impairments. Those who had been working 21-30 years had a seven-fold increased risk of developing hearing and balance impairments (adjusted OR = 7.11; 95% CI = 1.88-26.92. To minimize hearing and balance impairments bajaj drivers are recommended to work less than 8 hours a day.

    Childhood hearing impairment is a significant cause of disability in developing countries. Otitis media and meningitis are leading infectious causes of preventable hearing loss in children. It is estimated that the Pacific Islands have among the greatest global burden of childhood hearing impairment due to infectious causes, and yet there is currently very little in the research literature on pediatric hearing disorders in this region. (1) To review existing research literature on pediatric hearing impairment in the Pacific Islands, and (2) to present a public health approach to the development and improvement of childhood hearing services in the Pacific Islands. The primary tool was a comprehensive literature review. MEDLINE and ScienceDirect databases were searched for relevant journal articles. There was no limit on the date of publication. Any article reporting on hearing impairment in the Pacific Region was included. A total of 23 journal articles were found that satisfied the above inclusion criteria. The limited information available in the literature suggests that otitis media and vaccine-preventable infections are a significant cause of avoidable childhood hearing impairment in the Pacific Islands. Pediatric audiology services are limited in this region. Further research is required to develop effective public health programs that should reduce the burden of preventable childhood hearing loss in the Pacific Islands. There is limited information in the research literature on pediatric hearing impairment and audiology services in the Pacific Islands. Epidemiological data based on the WHO Ear and Hearing Disorders Survey Protocol are urgently needed, and the development of audiology services within the existing public and primary health care framework should reduce the burden of preventable hearing loss in the Pacific Islands.

    Riding therapy is a comprehensive and functional form of rehabilitation, in which the rehabilitee, the horse and the riding therapist collaborate in order to achieve individually assigned goals that support rehabilitation. In Finland, riding therapy is therapeutic rehabilitation carried out by riding therapists who have undergone approved training. The therapy is mainly implemented in an individual form, but small group working is also applied, e.g. in the form of pair therapy and therapeutic vaulting. In Europe, this form of rehabilitation has been divided into hippotherapy supporting motor functions and heilpedagogical riding therapy functioning in support of upbringing.

    Although educational main streaming of children with special needs formally began in Iran since 1992 there is little information whether hearing impaired children feel competent in regular schools. To determine the perceived competence and school adjustment of hearing impaired children in mainstream primary school settings, the self-perception profile was administered to 60 mainstreamed hard of hearing children and 60 classmates with normal hearing matched for gender by a single interviewer. The instrument comprised 28 items, 23 of which were similar to those of 'adapted test Image for children with cochlear implants' asking children about their feelings about their own cognitive, physical, socio-emotional and communication competence and school adjustment. The Cronbach alpha coefficient for the instrument was 0.93. Hard of hearing children rated their competence significantly poorer than their hearing classmates for all domains. Mean differences for the five domains ranged from 0.48 (for physical competence) to 0.90 (for school adjustment) on a scale of 1-4. There were no significant differences between girls' and boys' competence, in either the hearing or the hearing impaired groups. Classifying overall scores for perceived competence into four groups ('poor competence', 'low competence', 'moderate competence' and 'high competence'), 23.4% of hearing impaired children but none of the hearing classmates rated themselves as having low or poor competence. On the other hand 85% of hearing children and only 18.3% of hearing impaired children rated themselves as highly competent. We suggest that periodical assessments of mainstreamed children might help to identify those children who are having difficulty adapting to their environment.

    Mutations in EYA4 can cause nonsyndromic autosomal dominant sensorineural hearing impairment (DFNA10) or a syndromic variant with hearing impairment and dilated cardiomyopathy. A mutation in EYA4 was found in a Dutch family, causing DFNA10. This study is focused on characterizing the hearing impairment in this family. Whole exome sequencing was performed in the proband. In addition, peripheral blood samples were collected from 23 family members, and segregation analyses were performed. All participants underwent otorhinolaryngological examinations and pure-tone audiometry, and 12 participants underwent speech audiometry. In addition, an extended set of audiometric measurements was performed in five family members to evaluate the functional status of the cochlea. Vestibular testing was performed in three family members. Two individuals underwent echocardiography to evaluate the nonsyndromic phenotype. The authors present a Dutch family with a truncating mutation in EYA4 causing a mid-frequency hearing impairment. This mutation (c.464del) leads to a frameshift and a premature stop codon (p.Pro155fsX). This mutation is the most N-terminal mutation in EYA4 found to date. In addition, a missense mutation, predicted to be deleterious, was found in EYA4 in two family members. Echocardiography in two family members revealed no signs of dilated cardiomyopathy. Results of caloric and velocity step tests in three family members showed no abnormalities. Hearing impairment was found to be symmetric and progressive, beginning as a mid-frequency hearing impairment in childhood and developing into a high-frequency, moderate hearing impairment later in life. Furthermore, an extended set of audiometric measurements was performed in five family members. The results were comparable to those obtained in patients with other sensory types of hearing impairments, such as patients with Usher syndrome type IIA and presbyacusis, and not to those obtained in patients with (cochlear

    Full Text Available The aim of the following study was to examine the relationship between working memory capacity (WMC, executive functions (EFs and perceived effort (PE after completing a work-related task in quiet and in noise in employees with aided hearing impairment (HI and normal hearing. The study sample consisted of 20 hearing-impaired and 20 normally hearing participants. Measures of hearing ability, WMC and EFs were tested prior to performing a work-related task in quiet and in simulated traffic noise. PE of the work-related task was also measured. Analysis of variance was used to analyze within- and between-group differences in cognitive skills, performance on the work-related task and PE. The presence of noise yielded a significantly higher PE for both groups. However, no significant group differences were observed in WMC, EFs, PE and performance in the work-related task. Interestingly, significant negative correlations were only found between PE in the noise condition and the ability to update information for both groups. In summary, noise generates a significantly higher PE and brings explicit processing capacity into play, irrespective of hearing. This suggest that increased PE involves other factors such as type of task that is to be performed, performance in the cognitive skill required solving the task at hand and whether noise is present. We therefore suggest that special consideration in hearing care should be made to the individual′s prerequisites on these factors in the labor market.

    This study explored the nature of audiological services for adults with hearing impairment in Malaysia, with an emphasis on whether current services address clients' overall functioning as described by the World Health Organisation's International Classification of Functioning, Disability, and Health (ICF) framework. An online survey exploring current practice, skills and confidence of audiologists, and the infrastructure and facilities available in their workplaces, was distributed to audiologists in Malaysia via professional associations and social media. A total of 111 audiologists, 84.7% female and 15.3% male (range = 23-44 years), participated in the study. Although audiologists in Malaysia reported addressing all of the ICF domains, less than 26% of them assessed the patients' speech perception, carried out real-ear measurements, or used outcome measures routinely. The majority of the audiologists reported feeling confident in managing adult patients. However, 83% of the audiologists indicated they wanted to improve their skills related to management of adult patients, particularly in the areas of counselling and auditory training. Inadequate infrastructure, resources and facilities in the workplace may have contributed to the gaps in service provision and influenced the current practice of audiological management for adult patients in Malaysia.

Each hearing loss in childhood influences, depending on the depth, nature and time of its inception, in a negative way on the development of many mental activities, intellectual, behavior, cognitive, causing significant impairment in the child's position the hearing impaired, deaf and especially in the world of the hearing. The aim of this study is to assess the parents' awareness of hearing loss in children with hearing loss as a result of a survey of parents of children from the first classes of primary schools in the Lublin province. Material and Methods Analysis was performed on 31 results of parents of children with hearing impairment made in children aged 6 and 7 years, pupils and primary schools in the Lublin province. Parents were asked the question: 'Do you think your child has hearing problems?' The analysis indicated the assessment of awareness of parents of children with hearing disorders.   Results In the study group, as many as 77% of parents stated that the child does not have problems with hearing, only 3% of parents noted the problem, while 20% of parents did not answer the question. Conclusions Based on the research it can be stated with a high percentage of parents still do not notice hearing loss in their children. Early notice of the problem, the correct procedure and the cooperation with the parent group of specialists are often the way to success. It is crucial to support the child in difficult situations, which often is exposed to contact with all sorts of obstacles. An important issue is the numerous health programs, shaping the attitude of parents and society as a whole.

    The goal was to examine the relationships between management after confirmation, family participation, and speech and language outcomes in the same group of children with permanent childhood hearing impairment. Speech, oral language, and nonverbal abilities, expressed as z scores and adjusted in a regression model, and Family Participation Rating Scale scores were assessed at a mean age of 7.9 years for 120 children with bilateral permanent childhood hearing impairment from a 1992-1997 United Kingdom birth cohort. Ages at institution of management and hearing aid fitting were obtained retrospectively from case notes. Compared with children managed later (> 9 months), those managed early (early did not have significantly higher scores for these outcomes. Family Participation Rating Scale scores showed significant positive correlations with language and speech intelligibility scores only for those with confirmation after 9 months and were highest for those with late confirmed, severe/profound, permanent childhood hearing impairment. Early management of permanent childhood hearing impairment results in improved language. Family participation is also an important factor in cases that are confirmed late, especially for children with severe or profound permanent childhood hearing impairment.

    Full Text Available Objectives: Auditory perception or hearing ability is critical for children in acquisition of language and speech hence hearing loss has different effects on individuals’ linguistic perception, and also on their functions. It seems that deaf people suffer from language and speech impairments such as in perception of complex linguistic constructions. This research was aimed to study the perception of complex syntactic constructions in children with hearing-impairment. Methods: The study design was case-control. According to the inclusion and exclusion criteria, twenty children with severe to profound hearing impairment, aged 8-12 years and twenty normal-hearing children, aged 6-7 years were selected in a simple random sampling from exceptional schools for deaf people and from normal kindergartens and schools for normal cases. The perception of sentences was tested by using a researcher-made task called sentence-picture matching task. At first the content validity was determined and then the reliability was confirmed with Cronbach Alpha Test. Data were analyzed by statistical tests such as Independent Samples T-Test and Mann-Whitney U Test using SPSS. Results: Perception of the group with hearing-impairment was significantly lower than the normal control group. The hearing-impaired children failed to perceive complex syntactic structures. Linguistic function of the group with hearing-impairment on perception of sentences with simple word order was better than on complex sentences. Discussion: If rich linguistic inputs are not available for children during the critical period of the first language acquisition, the syntactic skill, especially in complex syntactic constructions, will not normally develop. In order to establish a foundation for a healthy perfect development of syntax, at the early years of life, children should be exposed to a natural language.

    Hearing impairment and specific language disorder are two entities that seriously affect language acquisition in children and reduce their communication skills. These children require specific treatment and higher levels of care than healthy children. Their language abilities also strongly influence parent-child interactions. The purpose of our study was to evaluate the health-related quality of life (HRQOL) of the parents of hearing-impaired children and the parents of children with speech difficulties (specific language disorder). Our study subjects included 349 parents (182 mothers and 167 fathers) of preschool-aged children with receptive expressive language disorder and 131 parents (71 mothers and 60 fathers) of children with severe hearing impairment. A control group was composed of 146 parents (82 mothers and 64 fathers) of healthy children of the same age. HRQOL was assessed using the SF-36 questionnaire. For all groups of parents, the mothers had poorer scores compared with the fathers, but large differences were apparent depending on the child's impairment. In the control group, the scores of the mothers were significantly lower than the fathers' scores in only two (of eight) health domains. In contrast, the scores were lower in three domains for the mothers of speech-impaired children and in six domains for the mothers of hearing-impaired children, representing the greatest difference between the parents. When compared with the control group, both the mothers and fathers of speech-impaired children scored significantly worse in five health domains. Fathers of hearing-impaired children scored significantly worse than controls in three health domains. The lowest scores, indicating the poorest HRQOL, were observed for mothers of hearing-impaired children, who obtained significantly lower scores than the control mothers in all health domains except the emotional role. The parents of preschool-aged speech-and hearing-impaired children experience poorer HRQOL

    This work aimed to highlight a challenging asymptomatic problem which is early detection of hearing impairment in toddlers with protein energy malnutrition (PEM) as a neuro-cognitive effect of PEM on developing brain in relation to hemoglobin level. 100 toddlers, aged 6-24 months, fifty with moderate/severe PEM and fifty healthy children, were included in study. Both TEOAEs and ABR testing were used to assess auditory function. Study reported an association between malnutrition and hearing impairment, 26% of cases had conductive deafness secondary to otitis media with effusion using tympanometry; 84.6% showed type B and 15.4% type C which may suggest developing or resolving otitis media. Their ABR showed 46% mild and 53% moderate impairment. 32% of PEM cases had sensory neural hearing loss and with type (A) tympanometry. Those were assessed using ABR; 58% had mild, 34% moderate and 8% profound impairment. 10% of PEM cases had mixed hearing loss with 50% type B and 50% type C tympanometry and their ABR showed moderate to profound impairment. TEOAEs latencies at different frequencies correlate negatively with hemoglobin level. Toddlers with moderate/severe PEM had hearing impairments of different types and degrees. Neuro-physiological methods could be early and safe detectors of auditory disorders especially in high-risk toddlers. Anemia increases risk for auditory dysfunction.

    2016-07-01

    The transtheoretical model (TTM) of behaviour change focuses on clients' readiness for adopting new health behaviours. This study explores how clients' readiness for change can be identified through their interactions with audiologists during history-taking in initial appointments; and whether clients' readiness has consequences for the rehabilitation decisions they make within the initial appointment. Conversation analysis (CA) was used to examine video-recorded initial audiology appointments with older adults with hearing impairment. The data corpus involved 62 recorded appointments with 26 audiologists and their older adult clients (aged 55+ years). Companions were present in 17 appointments. Clients' readiness for change could be observed through their interaction with the audiologist. Analysis demonstrated that the way clients described their hearing in the history-taking phase had systematic consequences for how they responded to rehabilitation recommendations (in particular, hearing aids) in the management phase of the appointment. In particular, clients identified as being in a pre-contemplation stage-of-change were more likely to display resistance to a recommendation of hearing aids (80% declined). The transtheoretical model of behaviour change can be useful for helping audiologists individualize management planning to be congruent with individual clients' needs, attitudes, desires, and psychological readiness for action in order to optimize clients' hearing outcomes.

    Full Text Available We present a global overview of image- and video-processing-based methods to help the communication of hearing impaired people. Two directions of communication have to be considered: from a hearing person to a hearing impaired person and vice versa. In this paper, firstly, we describe sign language (SL and the cued speech (CS language which are two different languages used by the deaf community. Secondly, we present existing tools which employ SL and CS video processing and recognition for the automatic communication between deaf people and hearing people. Thirdly, we present the existing tools for reverse communication, from hearing people to deaf people that involve SL and CS video synthesis.

    Full Text Available Whereas the language development of children with sensorineural hearing impairment (SNHI has repeatedly been shown to differ from that of peers with normal hearing (NH, few studies have used an experimental approach to investigate the consequences on everyday communicative interaction. This mini review gives an overview of a range of studies on children with SNHI and NH exploring intra- and inter-individual cognitive and linguistic systems during communication.Over the last decade, our research group has studied the conversational strategies of Swedish speaking children and adolescents with SNHI and NH using referential communication, an experimental analogue to problem-solving in the classroom. We have established verbal and nonverbal control and validation mechanisms, related to working memory capacity (WMC and phonological short term memory (PSTM. We present main findings and future directions relevant for the field of cognitive hearing science and for the clinical and school-based management of children and adolescents with SNHI.

    This is the first cohort in which hearing impairment and external ear anomalies in Noonan Syndrome are described extensively. Retrospective analysis of the otorhinolaryngological and clinical genetic data from 97 Noonan Syndrome (NS) patients. Forty-four NS patients were seen by an otorhinolaryngologist for the analysis of hearing impairment. In our cohort 80 of the 97 patients were genetically tested. In 71 of these mutations were found: in 48 patients a mutation in PTPN11, in 10 patients in SOS1, in 5 patients in SHOC2, in 5 patients in RAF1, in 1 patient in MAP2K2, in 1 patient in KRAS and in 1 patient in A2ML1. External ear anomalies were reported in 75 NS patients (77%). In 69 patients the ears were low-set, 28 patients had posteriorly rotated ears, 14 patients showed protruding ears and 18 had thickened helices. Hearing impairment was detected in 34 NS patients. Nine patients had sensorineural hearing impairment, two a permanent conductive hearing impairment, two other patients had mixed hearing impairment and 20 patients had conductive hearing impairment in the past, caused by otitis media with effusion. Their temporary conductive hearing impairment resolved between the ages of 2 and 18 years. Sensorineural hearing impairment varied between mild high-frequency hearing impairment and profound (uni- and bilateral) hearing impairment and was progressive in three patients. Four NS patients received cochlear implants for their severe sensorineural hearing impairment. The cohort is small for genotype-phenotype correlations, but sensorineural hearing impairment, especially the bilateral severe hearing impairment, was only seen in patients with a PTPN11 mutation. NS is characterized by dysmorphic external ear anomalies and both sensorineural and conductive hearing impairment. Audiological examinations are recommended in all patients with Noonan Syndrome.

    To evaluate the impact of low vision rehabilitation on functional vision of children with visual impairment. The LV Prasad-Functional Vision Questionnaire, designed specifically to measure functional performance of visually impaired children of developing countries, was used to assess the level of difficulty in performing various tasks pre and post visual rehabilitation in children with documented visual impairment. Chi-square test was used to assess the impact of rehabilitation intervention on functional vision performance; a P visual acuity prior to the introduction of low vision devices (LVDs) was 0.90 ± 0.05 for distance and for near it was 0.61 ± 0.05. After the intervention, the acuities improved significantly for distance (0.2 ± 0.27; P visual rehabilitation was especially found in those activities related to their studying lifestyle like copying from the blackboard (P visual rehabilitation, especially with those activities which are related to their academic output. It is important for these children to have an early visual rehabilitation to decrease the impairment associated with these decreased visual output and to enhance their learning abilities.

    2011-06-01

    Full Text Available Background and Aim: Learning language is acquired in early childhood and gradually developed by new words and new structures. Hearing sense is the most important acquisition for learning this skill. Hearing disorders are barriers for natural language learning. The purpose of this study was to investigate the relationship between writing sentences and perception of written sentences in hearing-impaired and normal-hearing students.Methods: A cross-sectional study was conducted among thirty hearing-impaired students with hearing loss of 70-90 dB and thirty normal hearing students. They were selected from 3rd grade primary school students in Hamadan, a large city in Western Iran. The language skills and non language information was assessed by questionnaire, Action Picture Test, and Sentence Perception Test.Results: Results showed that there was a significant relation between writing sentences and perception of written sentences in hearing impaired students (p<0.001, (r=0.8. This significant relation was seen in normal-hearing students as well (p<0.001, (r=0.7.Conclusion: Disability of hearing-impaired students in verbal communication is not only related to articulation and voice disorders but also is related to their disability to explore and use of language rules. They suffer lack of perception of written sentences, and they are not skilled to convey their feelings and thoughts in order to presenting themselves by using language structures.

    To estimate the prevalence and causes of hearing impairment in Fundong Health District, North-West Cameroon. We selected 51 clusters of 80 people (all ages) through probability proportionate to size sampling. Initial hearing screening was undertaken through an otoacoustic emission (OAE) test. Participants aged 4+ years who failed this test in both ears or for whom an OAE reading could not be taken underwent a manual pure-tone audiometry (PTA) screening. Cases of hearing impairment were defined as those with pure-tone average ≥41 dBHL in adults and ≥35 dBHL in children in the better ear, or children under age 4 who failed the OAE test in both ears. Each case with hearing loss was examined by an ear, nose and throat nurse who indicated the main likely cause. We examined 3567 (86.9%) of 4104 eligible people. The overall prevalence of hearing impairment was 3.6% (95% confidence interval [CI]: 2.8-4.6). The prevalence was low in people aged 0-17 (1.1%, 0.7-1.8%) and 18-49 (1.1%, 0.5-2.6%) and then rose sharply in people aged 50+ (14.8%, 11.7-19.1%). Among cases, the majority were classified as moderate (76%), followed by severe (15%) and profound (9%). More than one-third of cases of hearing impairment were classified as unknown (37%) or conductive (37%) causes, while sensorineural causes were less common (26%). Prevalence of hearing impairment in North-West Cameroon is in line with the WHO estimate for sub-Saharan Africa. The majority of cases with known causes are treatable, with impacted wax playing a major role. © 2017 John Wiley & Sons Ltd.

    : Background: Older hospitalized adults with hearing impairment are vulnerable to adverse outcomes. These patients are at risk for being labeled confused, experiencing a loss of control, experiencing heightened fear and anxiety, and misunderstanding the plan of care. This qualitative study sought to assess the hospital experience of older adults with hearing impairment in order to formulate suggestions for improving nursing care. Open-ended interviews were conducted with eight participants, ages 70 to 95 years, who were identified as having a hearing impairment and were admitted as inpatients to a midwestern medical center. Through data analysis, three common themes emerged: health care communication difficulties, passivity and vulnerability, and frustration with family. Nurses will benefit from having a deeper understanding of the hospital experience of this vulnerable population. Efforts to address their needs can be accomplished through the following nursing actions: assess, accommodate, educate, empower, and advocate.

    2012-01-01

    Background Telephone communication is a challenge for many hearing-impaired individuals. One important technical reason for this difficulty is the restricted frequency range (0.3–3.4 kHz) of conventional landline telephones. Internet telephony (voice over Internet protocol [VoIP]) is transmitted with a larger frequency range (0.1–8 kHz) and therefore includes more frequencies relevant to speech perception. According to a recently published, laboratory-based study, the theoretical advantage of ideal VoIP conditions over conventional telephone quality has translated into improved speech perception by hearing-impaired individuals. However, the speech perception benefits of nonideal VoIP network conditions, which may occur in daily life, have not been explored. VoIP use cannot be recommended to hearing-impaired individuals before its potential under more realistic conditions has been examined. Objective To compare realistic VoIP network conditions, under which digital data packets may be lost, with ideal conventional telephone quality with respect to their impact on speech perception by hearing-impaired individuals. Methods We assessed speech perception using standardized test material presented under simulated VoIP conditions with increasing digital data packet loss (from 0% to 20%) and compared with simulated ideal conventional telephone quality. We monaurally tested 10 adult users of cochlear implants, 10 adult users of hearing aids, and 10 normal-hearing adults in the free sound field, both in quiet and with background noise. Results Across all participant groups, mean speech perception scores using VoIP with 0%, 5%, and 10% packet loss were 15.2% (range 0%–53%), 10.6% (4%–46%), and 8.8% (7%–33%) higher, respectively, than with ideal conventional telephone quality. Speech perception did not differ between VoIP with 20% packet loss and conventional telephone quality. The maximum benefits were observed under ideal VoIP conditions without packet loss and

    Full Text Available Background Annual four to five thousand babies are born with hearing loss in the Iran. Hearing impairment is a disability that affects the quality of life of people with this problem. These individuals need to support from family and friends because of their specific conditions that this received support has impact on their quality of life. This study was conducted to assess the status of perceived social support and quality of life of hearing-impaired adolescent. Material and Methods A cross-correlation study was performed with cluster and multi stage random sampling method on 83 students with hearing impairment who met the inclusion criteria of the study in Mashhad. The data collection tools included Pediatric quality of life inventory (adolescent form and perceived social support inventory (from family and friends.The data obtained from the questionnaires were analyzed through SPSS software version 16. Results The results showed that the majority of the most of adolescents with hearing impairment were reported moderate total quality of life (%51.8. But the majority of them reported perceived social support from family was moderate (%61.5 and from friends was week (%45.8. Also there was a significant relationship between category of total quality of life of adolescent viewpoint with perceived social support from family (P=0.056. Conclusion Based on the obtained results, the majority of the most of adolescents with hearing impairment were reported moderate total quality of life. Disability and condition of these persons affects quality of life of them, so need for adequate support from family, friends and society. Nurses play an important role in identifying and introduce these needs and condition and how to deal with them.

    1983-10-01

    Speech intelligibility (PB words) in traffic-like noise was investigated in a laboratory situation simulating three common listening situations, indoors at 1 and 4 m and outdoors at 1 m. The maximum noise levels still permitting 75% intelligibility of PB words in these three listening situations were also defined. A total of 269 persons were examined. Forty-six had normal hearing, 90 a presbycusis-type hearing loss, 95 a noise-induced hearing loss and 38 a conductive hearing loss. In the indoor situation the majority of the groups with impaired hearing retained good speech intelligibility in 40 dB(A) masking noise. Lowering the noise level to less than 40 dB(A) resulted in a minor, usually insignificant, improvement in speech intelligibility. Listeners with normal hearing maintained good speech intelligibility in the outdoor listening situation at noise levels up to 60 dB(A), without lip-reading (i.e., using non-auditory information). For groups with impaired hearing due to age and/or noise, representing 8% of the population in Sweden, the noise level outdoors had to be lowered to less than 50 dB(A), in order to achieve good speech intelligibility at 1 m without lip-reading.

    Following current prognosis, demographic development raises expectations of an aging of the working population. Therefore, keeping employees healthy and strengthening their ability to work, becomes more and more important. When employees become older, dealing with age-related impairments of sensory functions, such as hearing impairment, is a central issue. Recent evidence suggests that negative effects that are associated with reduced hearing can have a strong impact at work. Especially under exhausting working situations such as working overtime hours, age and hearing impairment might influence employees’ well-being. Until now, neither the problem of aged workers and long working hours, nor the problem of hearing impairment and prolonged working time has been addressed explicitly. Therefore, a laboratory study was examined to answer the research question: Do age and hearing impairment have an impact on psychophysiological and subjective effects of long working hours. In total, 51 white-collar workers, aged between 24 and 63 years, participated in the laboratory study. The results show no significant effects for age and hearing impairment on the intensity of subjective consequences (perceived recovery and fatigue, subjective emotional well-being and physical symptoms) of long working hours. However, the psychophysiological response (the saliva cortisol level) to long working hours differs significantly between hearing impaired and normal hearing employees. Interestingly, the results suggest that from a psychophysiological point of view long working hours were more demanding for normal hearing employees. PMID:29379452

    The study was undertaken to procure population-based prevalence data on the various types of Usher syndrome and other retinal dystrophy-hearing impairment associations. The medical files on 646 patients with a panretinal pigmentary dystrophy aged 20-49 years derived from the Danish Retinitis Pigmentosa (RP) register were scrutinised. The data were supplemented by a prior investigation on hearing ability in a part of the study population. After exclusion of patients with possibly extrinsic causes of hearing impairments, 118 patients, including 89 cases of Usher syndrome were allocated to one of five clinically defined groups. We calculated the following prevalence rates: Usher syndrome type I: 1.5/100,000, Usher syndrome type II: 2.2/100,000, and Usher syndrome type III: 0.1/100,000 corresponding to a 2:3 ratio between Usher syndrome type I and II. The overall prevalence rate of Usher syndrome was estimated to 5/100,000 in the Danish population, devoid of genetic isolates. The material comprised 11 cases with retinal dystrophy, hearing impairment, and additional syndromic features. Finally, 18 subjects with various retinal dystrophy-hearing impairment associations without syndromic features were identified, corresponding to a prevalence rate of 0.8/100,000. This group had a significant overrepresentation of X-linked RP, including two persons harboring a mutation in the retinitis pigmentosa GTP-ase regulator (RPGR) gene.

    Nowadays, designers are more concern with the issue of engagement and informal learning at museum and gallery sites. This has made studies to focus more on the use of Mobile Augmented Reality (MAR) at museum and gallery sites. However, most of the MAR applications for museum visitors are largely tailored to normal hearing visitors while the hearing-impaired (HI) visitors are not supported. The hearing impaired (HI) community account for over 5% of the world's populace which is about 360 million people. Thus, this paper explores the design elements of mobile augmented reality for engaging hearing impaired visitors at the museum site. The findings of this paper argues that there are eleven major elements of engagement of MAR needed for the design of an efficient museum MAR app for hearing impaired visitors. These eleven elements include Aesthetics, Curiosity, Usability, Interaction, Motivation, Satisfaction, Self-Efficacy, Perceived Control, Enjoyment, Focused Attention and Interest. This study pointed out that for an efficient and engaged MAR app for the HI community especially HI visitors to museum sites, these eleven elements are critical. This finding will help MAR designers and developers on how to design an efficient and engaged MAR app for the HI community at large and museum HI visitors specifically.

    In the development of software for voice analysis or training, for people with hearing impairments, a database having sounds of properly pronounced words is of paramount importance. This paper shows the advantage that will be obtained from getting an own voice database, rather than using those coming from other countries, even having the same language, in the development of speech training software aimed to people with hearing impairments. This database will be used by software developers at the School of Engineering of Mar del Plata National University.

    In the context of permanent childhood hearing loss, early audiological diagnosis is a prerequisite for activation of an adequate rehabilitation program to prevent or limit the known effects that auditory deprivation determines on language development and cognitive skills in neonates. Audiological diagnosis consists schematically of three phases: identification of subjects at risk, definition of hearing loss and/or children features, verification of appropriateness of diagnosis itself and a rehabilitation programme. Strategies and methods of audiological diagnosis are well defined and include an integration of data coming from objective methods with clinical and behavioural data. Although the substantial effectiveness of procedures and a general consensus on their use and interpretation have been defined, there are several critical issues concerning the achievement of this objective, which will be discussed in this paper. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale.

    Full Text Available Based on demographic prognoses, it must be assumed that a greater number of older workers will be found in the future labor market. How to deal with their possible age-related impairments of sensory functions, like hearing impairment and work performance during extended working time, has not been addressed explicitly until now. The study addresses this interplay. The study was performed on two consecutive days after normal working hours. The 55 participants had to “work” in the study at least three additional hours to simulate a situation of long working hours. The tested measures for (job performance were: general attention, long-term selective attention, concentration, and reaction time. All of the investigated variables were taken at both days of the study (2 × 2 × 2 repeated measurement design. The results show effects for age, the interaction of hearing impairment and time of measurement, and effects of the measurement time. Older participants reacted slower than younger participants did. Furthermore, younger participants reacted more frequently in a correct way. Hearing impairment seems to have a negative impact especially on measures of false reactions, and therefore especially on measurement time 1. The results can be interpreted in a way that hearing-impaired participants are able to compensate their deficits over time.

    Hearing impairment in children across the world constitutes a particularly serious obstacle to their optimal development and education, including language acquisition. Around 0.5-6 in every 1000 neonates and infants have congenital or early childhood onset sensorineural deafness or severe-to-profound hearing impairment, with significant consequences. Therefore, early detection is a vitally important element in providing appropriate support for deaf and hearing-impaired babies that will help them enjoy equal opportunities in society alongside all other children. This analysis estimates the costs and effectiveness of various interventions to screen infants at risk of hearing impairment. The economic analysis used a decision tree approach to determine the cost-effectiveness of newborn hearing screening strategies. Two unique models were built to capture different strategic screening decisions. Firstly, the cost-effectiveness of universal newborn hearing screening (UNHS) was compared to selective screening of newborns with risk factors. Secondly, the cost-effectiveness of providing a one-stage screening process vs. a two-stage screening process was investigated. Two countries, the United Kingdom and India, were used as case studies to illustrate the likely cost outcomes associated with the various strategies to diagnose hearing loss in infants. In the UK, the universal strategy incurs a further cost of approximately £2.3 million but detected an extra 63 cases. An incremental cost per case detected of £36,181 was estimated. The estimated economic burden was substantially higher in India when adopting a universal strategy due to the higher baseline prevalence of hearing loss. The one-stage screening strategy accumulated an additional 13,480 and 13,432 extra cases of false-positives, in the UK and India respectively when compared to a two-stage screening strategy. This represented increased costs by approximately £1.3 million and INR 34.6 million. The cost

    Full Text Available Introduction Hearing impairment contributes greatly to social and psychological deficits of the affected individuals, which can affect their interpersonal relation. The inability to hear and communicate effectively results in adjustment problem that leads to social isolation. Objectives: The objective of this study is to examine the relationship between life building skills and social adjustment of students with hearing impairment. Methods: The study employed descriptive survey research design. The samples consisted of 150 students with hearing impairment purposively selected from two inclusive schools in Lagos state, Nigeria. The samples comprised of 65 boys and 85 girls with age range between 15 and 18 years in the Senior Secondary School. The instruments used for data collection were Life building skills inventory (adapted with reliability of 0.80 and Social adjustment scale (Self developed. The instruments consisted of two sections namely: A&B. Section A of Life building skills contained bio- data of the respondents, while B contained 3 subscales: Self-efficacy inventory adapted from Schwarzer and Jerusalem 1995 with reliability of 0.85, Decision-making inventory adapted from Rowe 1997 with reliability of 0.75, Assertiveness inventory adapted from Aberti and Emmons 1995 with reliability of 0.80. The self-constructed Social Adjustment scale contained 10 items probing questions with reliability of 0.69. Data collected was analysed using Pearson Product Moment Correlation and Multiple Regression. Results: The results revealed relative contributions of some life building skills to social adjustment of students with hearing impairment. There were joint contributions of the independent variables to dependent variable, while decision-making contributed mostly. Conclusion: This study examined relationship between life building skills and social adjustment of students with hearing impairment with a bid to provide adequate counseling services. It was

    Full Text Available Background and Aim: Stress is associated with life satisfaction and also development of some physical diseases. Birth of a disabled child with mental or physical disability (especially deaf or blind children, impose an enormous load of stress on their parents especially the mothers. This study compared stress levels of mothers with hearing impaired children and mothers of normal children or with other disabilities.Methods: In this study, cluster random sampling was performed in Karaj city. 120 mothers in four groups of having a child with mental retardation, low vision, hearing impairment and with normal children were included. Family inventory of life events (FILE of Mc Cubbin et al. was used to determine stress level in four groups of mothers.Results: The results of this research indicated a significant difference (p<0.05 between stress levels of mothers with hearing impaired children and mothers of other disabled and normal children in subscales of intra-family stress, finance and business strains, stress of job transitions, stress of illness and family care and family members "in and out''. There was no difference between compared groups in other subscales.Conclusion: Since deafness is a hidden inability, the child with hearing impairment has a set of social and educational problems causing great stress for parents, especially to mother. In order to decrease mother’s stress, it is suggested to provide more family consultation, adequate social support and to run educational classes for parents to practice stress coping strategies.

    Full Text Available Background and Aim: Research indicates that impaired hearing is one of the most stressful disabilities. The parenting stress involved could lead to family malfunction and improper parenting. Therefore, this study aimed to evaluate the effects of positive parenting programs on the parenting stress of mothers with impaired hearing children.Methods: The statistical population comprised mothers of all 7-12-year-old impaired hearing children in Tehran city. Thereafter, using the random sampling method, 24 individuals were shortlisted as research participants and were randomly assigned to two groups: control and experimental. The experimental group was trained with a positive parenting program based on the Sanders program (1993 over eight sessions. The measurement instrument was the Abidin parenting stress questionnaire.Results: The mean score for grades in the experimental groups’ parent and child domains at the pre- and post-test stages had reduced more than that in the control group. In addition, the results of a multivariate covariance analysis indicated that positive parenting training was effective in the reduction of parenting stress scores, reinforcement, and child mood components in the child domain, and in the feelings of competence, relationships with the spouse, and role limitation components (p<0.05 in the parent domain.Conclusion : Considering the benefits of training parents for the reduction of parenting stress of mothers with impaired hearing children, this method is recommended in all learning centers for the deaf.

    Full Text Available Hearing impaired and normal hearing individuals were compared in two within-participant office noise conditions (high noise: 60 L Aeq and low noise: 30 L Aeq . Performance, subjective fatigue, and physiological stress were tested during working on a simulated open-plan office. We also tested two between-participants restoration conditions following the work period with high noise (nature movie or continued office noise. Participants with a hearing impairment (N = 20 were matched with normal hearing participants (N = 18 and undertook one practice session and two counterbalanced experimental sessions. In each experimental session they worked for two hours with basic memory and attention tasks. We also measured physiological stress indicators (cortisol and catecholamines and self-reports of mood and fatigue. The hearing impaired participants were more affected by high noise than the normal hearing participants, as shown by impaired performance for tasks that involve recall of semantic information. The hearing impaired participants were also more fatigued by high noise exposure than participants with normal hearing, and they tended to have higher stress hormone levels during the high noise compared to the low noise condition. Restoration with a movie increased performance and motivation for the normal hearing participants, while rest with continued noise did not. For the hearing impaired participants, continued noise during rest increased motivation and performance, while the movie did not. In summary, the impact of noise and restorative conditions varied with the hearing characteristics of the participants. The small sample size does however encourage caution when interpreting the results.

    2016-12-01

    Full Text Available The ability to communicate, specifically the gift of hearing, is a necessity often taken for granted. A lack of sense of hearing affects the intellectual and emotional development of the human being who suffers from it. It prevents the fluid exchange of knowledge, thoughts and ideas that allow personal growth and development. This article emerges due to an interest in providing assistive technologies that can be considered to improve communication among hearing impaired and normal hearing listeners in the class-room of a higher education level in the Republic of Panama. Information has been compiled from various primary and secondary sources highlighting the communication problem facing this group of disabled people. Information about the situation of hearing impairment, laws, organizations, the reality with the higher education system, and finally, we will talk about Information and Communication Technologies (TICs that will work as technology support in order to improve communication in the classroom in higher education among normal-hearing and deaf people.

    2018-01-01

    Poor communication between the Registered Nurse and a hearing impaired patient can affect quality of care and health outcomes. Communication skills training programs for healthcare providers are needed to improve patient centered care. A descriptive research study, using a knowledge assessment tool developed and validated by the researcher, was conducted on 339 Registered Nurses to identify knowledge deficits to be addressed in a communication skills training program being designed. The educational tool measured the Registered Nurses' knowledge across four areas - hearing impairment, hearing aids, communication strategies, and regulations regarding access to care for a person with a hearing disability. Knowledge deficits were detected in all four areas. Using this educational assessment tool may enable nurse educators to tailor communication skills training programs to specifically address the gaps identified regarding hearing impairment and how to effectively communicate with the hearing impaired patient. Post training program, nurse educators can use the tool to evaluate effectiveness. Copyright © 2017 Elsevier Ltd. All rights reserved.

    This study aims to review the relationship between written language skills and factors which are thought to affect this skill such as mean hearing loss, duration of auditory deprivation, speech discrimination score, and pre-school education attendance and socioeconomic status of hearing impaired children who attend 4th-7th grades in primary school in inclusive environment. The study included 25 hearing impaired children (14 males, 11 females; mean age 11.4±1.4 years; range 10 to 14 years) (study group) and 20 children (9 males, 11 females; mean age 11.5±1.3 years; range 10 to 14 years) (control group) with normal hearing in the same age group and studying in the same class. Study group was separated into two subgroups as group 1a and group 1b since some of the children with hearing disability used hearing aid while some used cochlear implant. Intragroup comparisons and relational screening were performed for those who use hearing aids and cochlear implants. Intergroup comparisons were performed to evaluate the effect of the parameters on written language skills. Written expression skill level of children with hearing disability was significantly lower than their normal hearing peers (p=0.001). A significant relationship was detected between written language skills and mean hearing loss (p=0.048), duration of auditory deprivation (p=0.021), speech discrimination score (p=0.014), and preschool attendance (p=0.005), when it comes to socioeconomic status we were not able to find any significant relationship (p=0.636). It can be said that hearing loss affects written language skills negatively and hearing impaired individuals develop low-level written language skills compared to their normal hearing peers.

    Wolfram syndrome is a progressive neurodegenerative syndrome characterized by the features "DIDMOAD" (diabetes insipidus, diabetes mellitus, optic atrophy, and deafness). We sought to study the audiometric data of genotyped Wolfram syndrome patients with sensorineural hearing impairment. Pure tone threshold data of 23 Wolfram syndrome patients were used for cross-sectional analysis in subgroups (age less than 16 years or between 19 and 25 years, gender, and origin). All subgroups, with 1 exception, showed a fairly similar type of hearing impairment with, on average, thresholds of about 25 dB (range, 0 to 65 dB) at 0.25 to 1 kHz, gently sloping downward to about 60 dB (range, 25 to 95 dB) at 8 kHz. The subgroup of Dutch women, which was excluded from the calculations of the average hearing thresholds, showed a higher degree of hearing impairment. Only the latter subgroup showed progression; however, contrary to the previous longitudinal analysis, progression was not significant in the present cross-sectional analysis, presumably because of the high degree of cross-subject variability. This unique collection of audiometric data from genotyped Wolfram syndrome patients shows no substantial progression in sensorineural hearing impairment with advancing age, no relation to the types of WFS1 mutations identified, and, with exclusion of the subgroup of Dutch female patients, no significant sex-related differences.

    Full Text Available Background and Aim: Most of the studies indicates that the parents of the hearing impaired children show many mental health problems after the diagnosis of their children's hearing impairment. Counselling with the parents of the hearing impaired children is one of the most important goals of any early intervention program. This paper describes a study to determine the effectiveness of a group counselling programme for parents of hearing impaired children. Materials and Method: It was a semi-experimental study with a single group pretest-post test design. The participants were all the parents of hearing impaired children attending in an early intervention center. First the parents' mental health were assessed.Then the group counselling program was implemented. Program has involved six weekly 1.5 hour sessions. The format of each session included both lecture presentation and group discussion using cognitive behavioral procedure. Subjects were assessed before and immediately after group therapy by means of General Health Questionnaire(GHQ and Symptom Check List 90 (SCL-90 questionnaires. Resuts: The first part of the project had shown that over the half of the parents had considerable psychosocial morbidity. Comparisons showed a significant reduction from pretreatment to posttreatment in depression, anxiety and most of other psychological problems. Conclusion: The study supports the effectiveness of group therapy programs in the treatment of parents of hearing impaired children. Concerning the progress of early detection programs for the children's hearing impairment more studies should be done in the field of counseling with their parents.

    2016-01-01

    This article presents data on the prevalence of hearing impairment among the workers engaged in the main means of transportation(air and railway transport). They show that the relative frequency of occupational loss of hearing in the cockpit members of commercial aviation amounts to one third of all cases of analogous diseases in this country. The main professional groups of transport works suffering from hearing impairment are constituted by the representatives of the so-called elite specialities, such as flying crew personnel, locomotive engineers, and their assistants. This fact constitutes an important aspect (not only of medical but also of socio-economic significance) of the problem under consideration. The high prevalence of professional hearing impairment among the transport workers is attributable to the high noise level in the cabins of locomotives and aircraft cockpits as well as to the inadequate expert and diagnostic work or imperfection of the regulatory documentation.

    Previous studies have highlighted that narrative skill is critical to the development of the literacy skills by children. Children with cochlear implants (CI) and hearing aids (HA) may have problems in narrative development compared to peers with healthy hearing (HH). There is no exact data about the narrative writing ability of Persian-speaking students who are hearing-impaired. This study was undertaken to compare the microstructure and macrostructure scores for narrative writing of Persian-speaking students who are hearing-impaired and peers with HH. This was a cross-sectional descriptive-analytical study. The subjects were recruited from elementary schools in the city of Tehran. A total of 144 elementary school students were participated. The written narratives were elicited using a wordless pictorial storybook story. Three-way ANOVA with post hoc adjusted Bonferroni test was applied to determine the main effects and interactions of grounded variables on the microstructure and macrostructure components of narrative writing. No significant differences were observed in the macrostructure components of narrative writing between hearing-impaired and HH students. Factors analysis showed that the 4th grade HH students had significantly the highest scores, and the 3rd grade HA students had significantly the lowest scores in microstructure components of narrative writing. The findings revealed that hearing-impaired students similarly to their HH peers can transmit the main idea (macrostructure) of narrative writing, but show critical difficulties when using complete grammatical elements (microstructures) to form sentences to convey the idea in the narrative. © 2018 John Wiley & Sons Ltd.

    Objective Options for management of unilateral hearing loss (UHL) in children include conventional hearing aids, bone-conduction hearing devices, contralateral routing of signal (CROS) aids, and frequency-modulating (FM) systems. The objective of this study was to systematically review the current literature to characterize auditory outcomes of hearing rehabilitation options in UHL. Data Sources PubMed, EMBASE, Medline, CINAHL, and Cochrane Library were searched from inception to January 2016. Manual searches of bibliographies were also performed. Review Methods Studies analyzing auditory outcomes of hearing amplification in children with UHL were included. Outcome measures included functional and objective auditory results. Two independent reviewers evaluated each abstract and article. Results Of the 249 articles identified, 12 met inclusion criteria. Seven articles solely focused on outcomes with bone-conduction hearing devices. Outcomes favored improved pure-tone averages, speech recognition thresholds, and sound localization in implanted patients. Five studies focused on FM systems, conventional hearing aids, or CROS hearing aids. Limited data are available but suggest a trend toward improvement in speech perception with hearing aids. FM systems were shown to have the most benefit for speech recognition in noise. Studies evaluating CROS hearing aids demonstrated variable outcomes. Conclusions Data evaluating functional and objective auditory measures following hearing amplification in children with UHL are limited. Most studies do suggest improvement in speech perception, speech recognition in noise, and sound localization with a hearing rehabilitation device.

    -discrimination performance for NH listeners. It is unclear whether a comparable effect of musical training occurs for listeners whose sensory encoding of F0 is degraded. To address this question, F0 discrimination was investigated for three groups of listeners (14 young NH, 9 older NH and 10 HI listeners), each......Hearing-impaired (HI) listeners, as well as elderly listeners, typically have a reduced ability to discriminate the fundamental frequency (F0) of complex tones compared to young normal-hearing (NH) listeners. Several studies have shown that musical training, on the other hand, leads to improved F0...... including musicians and non-musicians, using complex tones that differed in harmonic content. Musical training significantly improved F0 discrimination for all groups of listeners, especially for complex tones containing low-numbered harmonics.

    Since the psychosocial effects of hearing loss are different in the spouse (SP) than in the person with hearing loss (PHL), it seems reasonable that rehabilitation programs designed for PHLs may need to be adapted to benefit SPs. To evaluate the effectiveness of training in communication strategies and psychosocial exercises for SPs of PHLs by determining whether SPs who completed the group class had improved mood, reduced stress, improved marital communication, and greater awareness of their partners' hearing loss-related quality of life (HL-QOL) in comparison with SPs who did not participate in a group class. Additionally, to determine whether PHLs of SPs who participated in a group audiological rehabilitation (AR) class had significantly improved mood, reduced stress, improved marital communication, and better HL-QOL scores in comparison with PHLs whose SPs did not participate in a group class. A randomized controlled study. A total of 72 individuals participated in the study, 36 PHLs and 36 SPs. The PHLs were hearing aid users or cochlear implant users; the SPs had normal or near normal hearing. PHLs in the control group participated in a traditional group AR program while their SPs received no treatment. PHLs in the experimental group also participated in a traditional group AR program while their SPs participated in a treatment program designed for SPs of PHLs. Classes consisted of 90 min sessions meeting once a week for four weeks. All participants completed questionnaires measuring HL-QOL (the SPs filled out third-party reports of HL-QOL), stress, mood (positive affect and negative affect), and communication in the marriage. Scales were completed three times: prior to the AR program, within two weeks after completing the AR program, and 6 mo later. SP awareness of their PHL's HL-QOL was measured by comparing preclass and 6 mo scores with reported critical difference values. Preclass, postclass and 6 mo data were examined with repeated measures ANOVAs. All

    The objective of the present study was to examine the associations between various anthropometric measures and metabolic syndrome and hearing impairment in Asian women. We identified 11,755 women who underwent voluntary routine health checkups at Yeungnam University Hospital between June 2008 and April 2014. Among these patients, 2,485 participants were <40 years old, and 1,072 participants lacked information regarding their laboratory findings or hearing and were therefore excluded. In total 8,198 participants were recruited into our study. The AUROC value for metabolic syndrome was 0.790 for the waist to hip ratio (WHR). The cutoff value was 0.939. The sensitivity and specificity for predicting metabolic syndrome were 72.7% and 71.7%, respectively. The AUROC value for hearing loss was 0.758 for WHR. The cutoff value was 0.932. The sensitivity and specificity for predicting hearing loss were 65.8% and 73.4%, respectively. The WHR had the highest AUC and was the best predictor of metabolic syndrome and hearing loss. Univariate and multivariate linear regression analyses showed that WHR levels were positively associated with four hearing thresholds including averaged hearing threshold and low, middle, and high frequency thresholds. In addition, multivariate logistic analysis revealed that those with a high WHR had a 1.347-fold increased risk of hearing loss compared with the participants with a low WHR. Our results demonstrated that WHR may be a surrogate marker for predicting the risk of hearing loss resulting from metabolic syndrome.

    Objectives In the present study, we aimed to determine the effect of both active and passive smoking on the prevalence of the hearing impairment and the hearing thresholds in different age groups through the analysis of data collected from the Korea National Health and Nutrition Examination Survey (KNHANES). Study Design Cross-sectional epidemiological study. Methods The KNHANES is an ongoing population study that started in 1998. We included a total of 12,935 participants aged ≥19 years in the KNHANES, from 2010 to 2012, in the present study. Pure-tone audiometric (PTA) testing was conducted and the frequencies tested were 0.5, 1, 2, 3, 4, and 6 kHz. Smoking status was categorized into three groups; current smoking group, passive smoking group and non-smoking group. Results In the current smoking group, the prevalence of speech-frequency bilateral hearing impairment was increased in ages of 40−69, and the rate of high frequency bilateral hearing impairment was elevated in ages of 30−79. When we investigated the impact of smoking on hearing thresholds, we found that the current smoking group had significantly increased hearing thresholds compared to the passive smoking group and non-smoking groups, across all ages in both speech-relevant and high frequencies. The passive smoking group did not have an elevated prevalence of either speech-frequency bilateral hearing impairment or high frequency bilateral hearing impairment, except in ages of 40s. However, the passive smoking group had higher hearing thresholds than the non-smoking group in the 30s and 40s age groups. Conclusion Current smoking was associated with hearing impairment in both speech-relevant frequency and high frequency across all ages. However, except in the ages of 40s, passive smoking was not related to hearing impairment in either speech-relevant or high frequencies. PMID:26756932

    Full Text Available Objective: Genetic studies show that consanguineous marriage can increase the probability of incidence of genetic impairments such as hearing impairments. The target of this study is to identify the prevalence of consanguinity among the parents of hearing impaired students in primary schools. Materials and Methods: We selected all of deaf students of Tehran (614 students. Their mothers answered to questionnaires. The questions were about Risk Factors of deafness in mother pregnancy or in neonatal period. Results: from 614 students, 389 parents of them (64% had consanguineous marriage and 223 person (36% didn’t have this factor. 2 person did not answer to this question. In this study we observed that there is 32.3% family history of hearing loss, 29.2%deaf sister and brother, 17% ear infection history. Other risk factors were studied too. Also there is significant correlation between consanguinity and more than one deaf children in the family (p<0.005. Conclusion: According to high incidence of consanguinity (64%that was observed in this study it may be one of most important causes of sensory neural hearing loss in children, so we should give enough information about this problem to the people.

    Full Text Available Cotton ginning workers have a risk of hearing loss due to excessive noise levels at the workplace environment. In this study, estimates of typical sound levels prevailing at the workplace environment and its effects on hearing ability of the exposed workers were made among cotton ginning workers. Data on self-reported health status was collected by a questionnaire survey at 10 cotton ginning industries located at Jalgaon district of Maharashtra state, India. The cotton ginning workers were exposed to continuous noise levels between 89 and 106 dBA. The hearing ability of the subjects was accessed by pure tone audiometry. The results of audiometry show mild, moderate and moderately severe degree of hearing impairment among the cotton ginning workers. The data generated during the study show that hearing loss was significantly associated with period of exposure to the workplace noise (P <0.0001. The prevalence of audiometric hearing impairment defined as a threshold average greater than 25 dB hearing level was 96% for binaural low-frequency average, 97% for binaural mid frequency average and 94% for binaural high-frequency average in the cotton ginning workers. We recommend the compulsory use of personal protective equipment like ear plug by the cotton ginning workers at the workplace environment. A regular maintenance of ginning and pressing machineries will avoid the emission of excessive noise at the workplace environment of cotton gins. A regular periodic medical examination is necessary to measure the impact of workplace noise on the health of cotton ginning workers.

    Full Text Available In recent years, it has been postulated that cigarette smoking can aggravate noise-induced hearing loss. In this study, we aimed to assess the effect of concurrent exposure to cigarette smoke and occupational noise on binaural hearing impairment (BHI. In an analytic study on the workers of a large wagon manufacturing company in 2007, 622 male workers (252 smokers and 370 non-smokers, matched for other variables participated and their BHI was compared. BHI was significantly higher in smokers than in non-smokers (odds ratio= 5.6, P < 0.001, 95% CI =3.4-9.4. Logistic regression confirmed this significant difference as well, and showed a direct relationship between the amount of BHI and pack/years of smoking. Cigarette smoking accompanied by exposure to workplace noise may play a role in causing binaural hearing impairment, so giving up or decreasing the amount of smoking may prevent or at least delay binaural hearing impairment, and eventually reduce its compensation costs.

    Full Text Available In order to explore verbal-nonverbal integration, we investigated the influence of cognitive and linguistic ability on gaze behavior during spoken language conversation between children with mild-to-moderate hearing impairment (HI and normal-hearing (NH peers. Ten HI-NH and ten NH-NH dyads performed a referential communication task requiring description of faces. During task performance, eye movements and speech were tracked. Cox proportional hazards regression was used to model associations between performance on cognitive and linguistic tasks and the probability of gaze to the conversational partner’s face. Analyses compare the listeners in each dyad (HI: n = 10, mean age = 12;6 years, SD = 2;0, mean better ear pure-tone average 33.0 dB HL, SD = 7.8; NH: n = 10, mean age = 13;7 years, SD = 1;11. Group differences in gaze behavior – with HI gazing more to the conversational partner than NH – remained significant despite adjustment for ability on receptive grammar, expressive vocabulary, and complex working memory. Adjustment for phonological short term memory, as measured by nonword repetition, removed group differences, revealing an interaction between group membership and nonword repetition ability. Stratified analysis showed a twofold increase of the probability of gaze-to-partner for HI with low phonological short term memory capacity, and a decreased probability for HI with high capacity, as compared to NH peers. The results revealed differences in gaze behavior attributable to performance on a phonological short term memory task. Participants with hearing impairment and low phonological short term memory capacity showed a doubled probability of gaze to the conversational partner, indicative of a visual bias. The results stress the need to look beyond the hearing impairment in diagnostics and intervention. Acknowledgment of the finding requires clinical assessment of children with hearing impairment to be supported by tasks tapping

    To highlight Noonan syndrome as a clinically recognizable cause of severe to profound sensorineural hearing impairment. New clinical cases and review. Patients evaluated for etiological diagnosis by a medical geneticist in a reference center for hearing impairment. Five patients presenting with confirmed Noonan syndrome and profound sensorineural hearing impairment. Diagnostic and review of the literature. Five patients presented with profound sensorineural hearing impairment and molecularly confirmed Noonan syndrome. Sensorineural hearing impairment has been progressive for three patients. Cardiac echography identified pulmonary stenosis in two patients and was normal for the three other patients. Short stature was found in two patients. Mild intellectual disability was found in one patient. Inconspicuous clinical features as facial dysmorphism, cryptorchidism, or easy bruising were of peculiar interest to reach the diagnosis of Noonan syndrome. Profound sensorineural hearing impairment can be the main feature of Noonan syndrome. Associated features are highly variable; thus, detailed medical history and careful physical examination are mandatory to consider the diagnosis in case of a sensorineural hearing impairment.

  15. Investigation of in-vehicle speech intelligibility metrics for normal hearing and hearing impaired listeners

    Samardzic, Nikolina

    The effectiveness of in-vehicle speech communication can be a good indicator of the perception of the overall vehicle quality and customer satisfaction. Currently available speech intelligibility metrics do not account in their procedures for essential parameters needed for a complete and accurate evaluation of in-vehicle speech intelligibility. These include the directivity and the distance of the talker with respect to the listener, binaural listening, hearing profile of the listener, vocal effort, and multisensory hearing. In the first part of this research the effectiveness of in-vehicle application of these metrics is investigated in a series of studies to reveal their shortcomings, including a wide range of scores resulting from each of the metrics for a given measurement configuration and vehicle operating condition. In addition, the nature of a possible correlation between the scores obtained from each metric is unknown. The metrics and the subjective perception of speech intelligibility using, for example, the same speech material have not been compared in literature. As a result, in the second part of this research, an alternative method for speech intelligibility evaluation is proposed for use in the automotive industry by utilizing a virtual reality driving environment for ultimately setting targets, including the associated statistical variability, for future in-vehicle speech intelligibility evaluation. The Speech Intelligibility Index (SII) was evaluated at the sentence Speech Receptions Threshold (sSRT) for various listening situations and hearing profiles using acoustic perception jury testing and a variety of talker and listener configurations and background noise. In addition, the effect of individual sources and transfer paths of sound in an operating vehicle to the vehicle interior sound, specifically their effect on speech intelligibility was quantified, in the framework of the newly developed speech intelligibility evaluation method.

    High resolution CT scanning of the temporal bone in our clinic has provided a more detailed radiological classification of inner ear anomalies than before. The statistical analysis of inner ear malformations based on the theory of quantification II has produced discriminant equations for the measurable diagnosis of hearing impairment and development of the inner ear. This analysis may make it possible to diagnose total and partial deafness on ipsi- and contralateral sides. (author)

    Since the pragmatic skills of hearing-impaired Persian-speaking children have not yet been investigated particularly through story retelling, this study aimed to evaluate some pragmatic abilities of normal-hearing and hearing-impaired children using a story retelling test. 15 normal-hearing and 15 profound hearing-impaired 7-year-old children were evaluated using the story retelling test with the content validity of 89%, construct validity of 85%, and reliability of 83%. Three macro structure criteria including topic maintenance, event sequencing, explicitness, and four macro structure criteria including referencing, conjunctive cohesion, syntax complexity, and utterance length were assessed. The test was performed with live voice in a quiet room where children were then asked to retell the story. The tasks of the children were recorded on a tape, transcribed, scored and analyzed. In the macro structure criteria, utterances of hearing-impaired students were less consistent, enough information was not given to listeners to have a full understanding of the subject, and the story events were less frequently expressed in a rational order than those of normal-hearing group (P hearing students who obtained high scores, hearing-impaired students failed to gain any scores on the items of this section. These results suggest that Hearing-impaired children were not able to use language as effectively as their hearing peers, and they utilized quite different pragmatic functions.

    The purpose of this paper was to highlight the importance of cultural influence in understanding hearing-help seeking and hearing-aid uptake. Information on audiological services in different countries and 'theories related to cross-culture' is presented, followed by a general discussion. Twenty-seven relevant literature reviews on hearing impairment, cross-cultural studies, and the health psychology model and others as secondary resources. Despite the adverse consequences of hearing impairment and the significant potential benefits of audiological rehabilitation, only a small number of those with hearing impairment seek professional help and take up appropriate rehabilitation. Therefore, hearing help-seeking and hearing-aid uptake has recently become the hot topic for clinicians and researchers. Previous research has identified many contributing factors for hearing help-seeking with self-reported hearing disability being one of the main factors. Although significant differences in help-seeking and hearing-aid adoption rates have been reported across countries in population studies, limited literature on the influence of cross-cultural factors in this area calls for an immediate need for research. This paper highlights the importance of psychological models and cross-cultural research in the area of hearing help-seeking and hearing-aid uptake, and consequently some directions for future research are proposed.

    The objective of the present study was to analyze the structure of concomitant somatic pathology in the subjects experiencing the occupational hearing problems. The study demonstrated the increase in the frequency of concomitant chronic diseases and the prevalence of polynosological conditions with the increasing severity of hearing impairment. It was shown that cardiovascular pathologies tend to enhance the risk of hearing loss in the employees engaged in «noisy» occupations. The cause-and-effect relationships were elucidated as the contribution of the "vascular" factor to the formation of occupational pathology of the organs of hearing. The clinical audilogical features of co-morbid occupational hearing impairment associated with vascular pathology were characterized by the accelerated development and progression of the hearing disorders with the gradual disappearance of the audiological signs characteristic of noise-induced lesions.

    2011-09-01

    Full Text Available The study identifies some self-regulation strategies used by deaf children in order to make their speech more intelligible. To achieve self-control while speaking, the child with severe hearing loss needs not only a high level of intelligence, but also an effective lip-reading capability and a strong intrinsic motivation. This is the reason why there are many cases of children with a high level of intelligence, but with a mediocre lip-reading capability and others with a lower level of intelligence, but with a good lip-reading capability. These differences also depend on the degree of hearing loss. Among the self-regulation strategies used by the children that achieve an intelligible speech are: the cognitive and meta-cognitive strategies, the motivational strategies etc. These results are important while designing the therapeutic activities, and especially the speech intelligibility factor being crucial in the social integration of those children with hearing impairment.

    Full Text Available Abstract Background When evaluating hearing rehabilitation, it is reasonable to use self-report questionnaires as outcome measure. Questionnaires used in audiological research are developed and validated for the paper-and-pencil format. As computer and Internet use is increasing, standardized questionnaires used in the audiological context should be evaluated to determine the viability of the online administration format. The aim of this study was to compare administration of questionnaires online versus paper- and pencil of four standardised questionnaires used in hearing research and clinic. We included the Hearing Handicap Inventory for the Elderly (HHIE, the International Outcome Inventory for Hearing Aids (IOI-HA, Satisfaction with Amplification in Daily Life (SADL, and the Hospital Anxiety and Depression Scale (HADS. Methods A cross-over design was used by randomly letting the participants complete the questionnaires either online or on paper. After 3 weeks the participants filled out the same questionnaires again but in the other format. A total of 65 hearing-aid users were recruited from a hearing clinic to participate on a voluntary basis and of these 53 completed both versions of the questionnaires. Results A significant main effect of format was found on the HHIE (p Conclusions For three of the four included questionnaires the participants’ scores remained consistent across administrations and formats. For the fourth included questionnaire (HHIE a significant difference of format with a small effect size was found. The relevance of the difference in scores between the formats depends on which context the questionnaire is used in. On balance, it is recommended that the administration format remain stable across assessment points.

    Hereditary hearing impairment (HI) caused by recessive GJB2 mutations is a frequent sensory disorder. The results of the molecular-based studies of HI are widely used in various genetic test systems. However, the ethical aspects are less described than the genetic aspects. The concerns expressed by individuals from groups with genetic risks must be included in the counseling of patients and their families. For evaluation of subjective opinions of hearing parents about the presumed causes of HI of their children, we analyze the cohort of parents having children with confirmed hereditary HI caused by biallelic recessive GJB2 mutations (in a homozygous or a compound heterozygous state). This study included 70 deaf children with HI due to mutations in the GJB2 gene and 91 questionnaires about the presumed causes of their deafness filled by their parents. Most of the parents at 78% (CI 68.4-85.4%) attributed their children's HI to "non-hereditary" causes and 22% (CI 14.7-31.6%) to "hereditary" causes (p < 0.05). Therefore, the prior opinions of the parents did not correspond to positive GJB2 genetic testing results. The subjective opinions of parents are probably partly based on family history, since respondents with deaf relatives in their pedigree more likely supposed hereditary causes for HI in their children than the respondents without deaf relatives (p < 0.001).

  8. Dynamic Range Across Music Genres and the Perception of Dynamic Compression in Hearing-Impaired Listeners

    2016-02-01

    Full Text Available Dynamic range compression serves different purposes in the music and hearing-aid industries. In the music industry, it is used to make music louder and more attractive to normal-hearing listeners. In the hearing-aid industry, it is used to map the variable dynamic range of acoustic signals to the reduced dynamic range of hearing-impaired listeners. Hence, hearing-aided listeners will typically receive a dual dose of compression when listening to recorded music. The present study involved an acoustic analysis of dynamic range across a cross section of recorded music as well as a perceptual study comparing the efficacy of different compression schemes. The acoustic analysis revealed that the dynamic range of samples from popular genres, such as rock or rap, was generally smaller than the dynamic range of samples from classical genres, such as opera and orchestra. By comparison, the dynamic range of speech, based on recordings of monologues in quiet, was larger than the dynamic range of all music genres tested. The perceptual study compared the effect of the prescription rule NAL-NL2 with a semicompressive and a linear scheme. Music subjected to linear processing had the highest ratings for dynamics and quality, followed by the semicompressive and the NAL-NL2 setting. These findings advise against NAL-NL2 as a prescription rule for recorded music and recommend linear settings.

By comparison, the dynamic range of speech, based on recordings of monologues in quiet, was larger than the dynamic range of all music genres tested. The perceptual study compared the effect of the prescription rule NAL-NL2 with a semicompressive and a linear scheme. Music subjected to linear processing had the highest ratings for dynamics and quality, followed by the semicompressive and the NAL-NL2 setting. These findings advise against NAL-NL2 as a prescription rule for recorded music and recommend linear settings. © The Author(s) 2016.

    The present study assesses the ability of four listeners with high-frequency, bilateral symmetrical sensorineural hearing loss to localize and detect a broadband click train in the frontal-horizontal plane, in quiet and in the presence of a white noise. The speaker array and stimuli are identical to those described by Lorenzi et al. (in press). The results show that: (1) localization performance is only slightly poorer in hearing-impaired listeners than in normal-hearing listeners when noise is at 0 deg azimuth, (2) localization performance begins to decrease at higher signal-to-noise ratios for hearing-impaired listeners than for normal-hearing listeners when noise is at +/- 90 deg azimuth, and (3) the performance of hearing-impaired listeners is less consistent when noise is at +/- 90 deg azimuth than at 0 deg azimuth. The effects of a high-frequency hearing loss were also studied by measuring the ability of normal-hearing listeners to localize the low-pass filtered version of the clicks. The data reproduce the effects of noise on three out of the four hearing-impaired listeners when noise is at 0 deg azimuth. They reproduce the effects of noise on only two out of the four hearing-impaired listeners when noise is at +/- 90 deg azimuth. The additional effects of a low-frequency hearing loss were investigated by attenuating the low-pass filtered clicks and the noise by 20 dB. The results show that attenuation does not strongly affect localization accuracy for normal-hearing listeners. Measurements of the clicks' detectability indicate that the hearing-impaired listeners who show the poorest localization accuracy also show the poorest ability to detect the clicks. The inaudibility of high frequencies, "distortions," and reduced detectability of the signal are assumed to have caused the poorer-than-normal localization accuracy for hearing-impaired listeners.

    Executive dysfunctions are part of the clinical symptoms of a stroke and can inhibit the process of rehabilitation. Patients with impaired executive functions may manifest aggression, impulsiveness, impaired thinking and planning. The aim of this study was to assess the effect of the ischemic focus location on the effectiveness of physiotherapy in improving the executive functions in patients after stroke. Ninety patients after unilateral ischemic cerebral stroke were studied. We studied 45 patients treated at the Department of Rehabilitation and Physical Medicine of the WAM University Hospital of Lodz for 5 weeks. The rehabilitation program included: kinesitherapy, physiotherapy, speech therapy, psychological consultations and psychotherapy. The control group consisted of patients who were waiting for admission to the Department of Rehabilitation. The patients in both groups were divided into three subgroups with different locations of stroke: front, back and subcortical. Executive functions were measured by the Wisconsin Card Sorting Test (WCST), the trail making test (TMT - A, TMT - B), the verbal fluency test (VFT). Patients rehabilitated in the hospital with the front and subcortical lesion location reported improvement in executive functions in terms of a greater number of the analyzed indicators of the Wisconsin Card Sorting Test (WCST) than those with the back lesion location. Patients rehabilitated at home with the subcortical lesion location did not experience a significant improvement in executive functions in any of the analyzed indicators of the Wisconsin Card Sorting Test (WCST). Most of the indicators, with the exception of the total errors of Wisconsin Card Sorting Test (WCST) and TMT B, have not been modified by the location of stroke. Executive dysfunction occurs not only in patients with an anterior location of the stroke, but also in the posterior and subcortical locations. Patients with a subcortical location of the stroke require more

    Full Text Available CONTEXT AND OBJECTIVE: Nouns and verbs indicate actions in oral communication. However, hearing impairment can compromise the acquisition of oral language to such an extent that appropriate use of these can be challenging. The objective of this study was to compare the use of nouns and verbs in the oral narrative of hearing-impaired and hearing children. DESIGN AND SETTING: Analytical cross-sectional study at the Department of Speech-Language and Hearing Sciences, Universidade Federal de São Paulo. METHODS: Twenty-one children with moderate to profound bilateral neurosensory hearing impairment and twenty-one with normal hearing (controls were matched according to sex, school year and school type. A board showing pictures was presented to each child, to elicit a narrative and measure their performance in producing nouns and verbs. RESULTS: Twenty-two (52.4% of the subjects were males. The mean age was 8 years (standard deviation, SD = 1.5. Comparing averages between the groups of boys and girls, we did not find any significant difference in their use of nouns, but among verbs, there was a significant difference regarding use of the imperative (P = 0.041: more frequent among boys (mean = 2.91. There was no significant difference in the use of nouns and verbs between deaf children and hearers, in relation to school type. Regarding use of the indicative, there was a nearly significant trend (P = 0.058. CONCLUSION: Among oralized hearing-impaired children who underwent speech therapy, their performance regarding verbs and noun use was similar to that of their hearing counterparts.

  17. Selective attention in normal and impaired hearing.

    Shinn-Cunningham, Barbara G; Best, Virginia

    2008-12-01

    A common complaint among listeners with hearing loss (HL) is that they have difficulty communicating in common social settings. This article reviews how normal-hearing listeners cope in such settings, especially how they focus attention on a source of interest. Results of experiments with normal-hearing listeners suggest that the ability to selectively attend depends on the ability to analyze the acoustic scene and to form perceptual auditory objects properly. Unfortunately, sound features important for auditory object formation may not be robustly encoded in the auditory periphery of HL listeners. In turn, impaired auditory object formation may interfere with the ability to filter out competing sound sources. Peripheral degradations are also likely to reduce the salience of higher-order auditory cues such as location, pitch, and timbre, which enable normal-hearing listeners to select a desired sound source out of a sound mixture. Degraded peripheral processing is also likely to increase the time required to form auditory objects and focus selective attention so that listeners with HL lose the ability to switch attention rapidly (a skill that is particularly important when trying to participate in a lively conversation). Finally, peripheral deficits may interfere with strategies that normal-hearing listeners employ in complex acoustic settings, including the use of memory to fill in bits of the conversation that are missed. Thus, peripheral hearing deficits are likely to cause a number of interrelated problems that challenge the ability of HL listeners to communicate in social settings requiring selective attention.

    Hearing impairment is a growing physical disability affecting older adults and is an important physical health stressor, but few studies have examined it in relation to mental health outcomes and even fewer have considered the role of social support in buffering this relationship. The current study builds on the stress process framework and uses longitudinal data from three waves of the Health and Retirement Study (2006, 2010, 2014) to examine the relationship between hearing impairment and depressive symptoms among U.S. adults aged 50 and older (n = 6075). The analysis uses fixed-effects models to assess this relationship and examine the extent to which social support mediates (buffers) or moderates (interaction) the association. The results found that worse self-rated hearing was associated with a significant increase in depressive symptoms, even after controlling for sociodemographic factors. Social support did not buffer this relationship. Instead, social support interacted with hearing impairment: low levels of social support were associated with more depressive symptoms but only among people with poor self-rated hearing. Among those with excellent self-rated hearing, low levels of social support did not increase depressive symptoms. Moreover, high levels of social support reduced depressive symptoms for those with poor hearing. These findings suggest that hearing impairment is a chronic stressor in individuals' lives, and that responses to this stressor vary by the availability of social resources.

    Continuous cycling peritoneal dialysis (CCPD) uses a cycler to perform dialysis exchanges and requires the patient to respond to an audible alarm signifying an interruption in the therapy. Consequently, an unassisted hearing-impaired patient could not use the system. By converting the standard alarm to a vibrating signal, the cycler was successfully adapted to accommodate the special needs of our hearing-impaired patient. The items required for the modification were the Sonic Alert Wake Up Alarm (Model SA-WA300: Sonic Alert, Troy, MI, U.S.A.) and the Sonic Alert Super Shaker Bed Vibrator (Model SA-SS120V: Sonic Alert). The patient can place the vibrator under either the pillow or the mattress. When the cycler alarm is activated, vibration wakens the patient. The equipment was purchased from Harris Communications (Eden Prairie, MN, U.S.A.) through a referral by the Easter Seal Society. Three days were needed to complete training compared to an average of one or two days for patients previously trained for continuous ambulatory peritoneal dialysis (CAPD). The patient remained on cycler therapy for approximately four months when the unrelated development of an abdominal hernia required termination of peritoneal dialysis and subsequent transfer to hemodialysis. In conclusion, a modified cycler can provide a safe and efficient renal replacement therapy option for a hearing-impaired patient.

  3. Cognitive rehabilitation of neuropsychological deficits and mild cognitive impairment: A review of the literature

    Eliane Correa Miotto

    Full Text Available Abstract Neuropsychological rehabilitation is related to the treatment or optimization of disabilities, handicaps and cognitive deficiencies including emotional, behavioral and personality alterations, aiming at the best cognitive, neurobiological and social re-adaptation. Objective: The main aim of this paper is to review scientific studies published over the last five years on cognitive training with rehabilitation, focusing on elderly subjects with cognitive complaints and patients diagnosed with MCI. Methods: Data were generated from Medline, PsychoInfo and EMBASE including publications from 2002 to 2007 using the search terms "Mild Cognitive Impairment", "Cognitive Complaints", "Rehabilitation" and "Intervention Studies". Data collection criteria were restricted to the quality of evidence Class I. Results: Eight articles out of sixty eight previously selected were chosen because of their randomized studies, including techniques of cognitive rehabilitation in patients with cognitive complaints, MCI and neuropsychological training. Conclusions: The studies showing generalization of rehabilitation techniques to practical real life situations and use of an errorless learning approach were considered more effective in terms of maintaining treatment follow up, although further studies are recommended.

    2012-12-01

    Brain injury is a major cause of long-term disability. Executive and social cognition sequelae are associated with poor outcome. This review examines recent evidence on the efficacy of rehabilitation in these areas. Accumulating evidence shows that interventions that work with patients on developing insight and strategies to offset executive impairments can produce significant benefits. Training of specific capacities, such as working memory, holds some promise, but more needs to be known about effect generalization. Evidence on social cognition rehabilitation following brain injury is sparse. Although there are some encouraging early results, more information on the clinical significance of change for everyday function is required. Rehabilitation in these areas is inherently difficult but vital if outcomes are to improve. Significant gains have been reported, and further work applying appropriate methods is urgently required.

    The present study investigated which additional cognitive and motor impairments were present in stroke patients with apraxia and which of these factors influenced the effects of treatment. A group of 33 patients with apraxia were treated according to the guidelines of a therapy programme based on teaching patients strategies to compensate for the presence of apraxia. Patients were treated at occupational therapy departments in general hospitals, rehabilitation centres and nursing homes. The outcome of the strategy training was studied in a pre-post test design; measurements were conducted at baseline and after 12 weeks of therapy. The pretreatment scores of the patients with apraxia were compared to normscores and scores of a control group of patients without apraxia (n = 36) to investigate which impairments are present. The following variables were analysed in order to determine which factors influence outcome: additional neuropsychological deficits (comprehension of language, cognitive impairments due to dementia, neglect and short term memory), level of motor functioning, severity of apraxia and performance on activities of daily living (ADL), and some relevant patient characteristics (gender, age, type of stroke, time since stroke, and location of treatment). The results showed that the presence of apraxia is associated with the presence of additional cognitive and motor impairments. The successful outcome of strategy training was not negatively influenced by cognitive comorbidity. The outcome seemed to be more prominent in patients who were more severely impaired at the start of rehabilitation in terms of the degree of motor impairments, the severity of apraxia and the initial ADL dependence. The ADL observations, however, displayed a ceiling effect, which was taken into account in discussing the results. Demographic variables, especially age, did not predict the outcome of treatment. We suggest that the effect of this training is stronger in more severely

    This study examined rapid word-learning in 5- to 14-year-old children with normal and impaired hearing. The effects of age and receptive vocabulary were examined as well as those of high-frequency amplification. Novel words were low-pass filtered at 4 kHz (typical of current amplification devices) and at 9 kHz. It was hypothesized that (1) the children with normal hearing would learn more words than the children with hearing loss, (2) word-learning would increase with age and receptive vocabulary for both groups, and (3) both groups would benefit from a broader frequency bandwidth. Sixty children with normal hearing and 37 children with moderate sensorineural hearing losses participated in this study. Each child viewed a 4-minute animated slideshow containing 8 nonsense words created using the 24 English consonant phonemes (3 consonants per word). Each word was repeated 3 times. Half of the 8 words were low-pass filtered at 4 kHz and half were filtered at 9 kHz. After viewing the story twice, each child was asked to identify the words from among pictures in the slide show. Before testing, a measure of current receptive vocabulary was obtained using the Peabody Picture Vocabulary Test (PPVT-III). The PPVT-III scores of the hearing-impaired children were consistently poorer than those of the normal-hearing children across the age range tested. A similar pattern of results was observed for word-learning in that the performance of the hearing-impaired children was significantly poorer than that of the normal-hearing children. Further analysis of the PPVT and word-learning scores suggested that although word-learning was reduced in the hearing-impaired children, their performance was consistent with their receptive vocabularies. Additionally, no correlation was found between overall performance and the age of identification, age of amplification, or years of amplification in the children with hearing loss. Results also revealed a small increase in performance for both

    Full Text Available Abstract Background Every year, 30,000 babies are born with congenital hearing impairment in China. The molecular etiology of hearing impairment in the Chinese population has not been investigated thoroughly. To provide appropriate genetic testing and counseling to families, we performed a comprehensive investigation of the molecular etiology of nonsyndromic deafness in two typical areas from northern and southern China. Methods A total of 284 unrelated school children with hearing loss who attended special education schools in China were enrolled in this study, 134 from Chifeng City in Inner Mongolia and the remaining 150 from Nangtong City in JiangSu Province. Screening was performed for GJB2, GJB3, GJB6, SLC26A4, 12S rRNA, and tRNAser(UCN genes in this population. All patients with SLC26A4 mutations or variants were subjected to high-resolution temporal bone CT scan to verify the enlarged vestibular aqueduct. Results Mutations in the GJB2 gene accounted for 18.31% of the patients with nonsyndromic hearing loss, 1555A>G mutation in mitochondrial DNA accounted for 1.76%, and SLC26A4 mutations accounted for 13.73%. Almost 50% of the patients with nonsyndromic hearing loss in these typical Chinese areas carried GJB2 or SLC26A4 mutations. No significant differences in mutation spectrum or prevalence of GJB2 and SLC26A4 were found between the two areas. Conclusion In this Chinese population, 54.93% of cases with hearing loss were related to genetic factors. The GJB2 gene accounted for the etiology in about 18.31% of the patients with hearing loss, SLC26A4 accounted for about 13.73%, and mtDNA 1555A>G mutation accounted for 1.76%. Mutations in GJB3, GJB6, and mtDNA tRNAser(UCN were not common in this Chinese cohort. Conventionally, screening is performed for GJB2, SLC26A4, and mitochondrial 12S rRNA in the Chinese deaf population.

    Full Text Available Background: In recent years there has been increased interest in the use of Al for assessing hearing handicap and for measuring the potential effectiveness of amplification system. AI is an expression of proportion of average speech signal that is audible to a given patient, and it can vary between 0.0 to 1.0. Method and Materials: This cross-sectional analytical study was carried out in department of audiology, rehabilitation, faculty, IUMS form 31 Oct 98 to 7 March 1999, on 40 normal hearing persons (80 ears; 19 males and 21 females and 40 hearing impaired persons (61 ears; 36 males and 25 females, 25-65 years old with moderate to moderately severe SNI-IL The pavlovic procedure (1988 for calculating Al, open set taped standard mono syllabic word lists, and the real -ear probe- tube microphone system to measure insertion gain were used, through test-retest. Results: 1/A significant correlation was shown between the Al scores and the speech recognition scores of normal hearing and hearing-impaired group with and without the hearing aid (P<0.05 2/ There was no significant differences in age group & sex: also 3 In test-retest measures of the insertion gain in each test and 4/No significant in test-retest of speech recognition test score. Conclusion: According to these results the Al can predict the unaided and aided monosyllabic recognition test scores very well, and age and sex variables have no effect on its ability. Therefore with respect to high reliability of the Al results and its simplicity, easy -to- use, cost effective, and little time consuming for calculation, its recommended the wide use of the Al, especially in clinical situation.

  14. Comparative multivariate analyses of transient otoacoustic emissions and distorsion products in normal and impaired hearing.

    2015-01-01

    The clinical utility of otoacoustic emissions as a noninvasive objective test of cochlear function has been long studied. Both transient otoacoustic emissions and distorsion products can be used to identify hearing loss, but to what extent they can be used as predictors for hearing loss is still debated. Most studies agree that multivariate analyses have better test performances than univariate analyses. The aim of the study was to determine transient otoacoustic emissions and distorsion products performance in identifying normal and impaired hearing loss, using the pure tone audiogram as a gold standard procedure and different multivariate statistical approaches. The study included 105 adult subjects with normal hearing and hearing loss who underwent the same test battery: pure-tone audiometry, tympanometry, otoacoustic emission tests. We chose to use the logistic regression as a multivariate statistical technique. Three logistic regression models were developed to characterize the relations between different risk factors (age, sex, tinnitus, demographic features, cochlear status defined by otoacoustic emissions) and hearing status defined by pure-tone audiometry. The multivariate analyses allow the calculation of the logistic score, which is a combination of the inputs, weighted by coefficients, calculated within the analyses. The accuracy of each model was assessed using receiver operating characteristics curve analysis. We used the logistic score to generate receivers operating curves and to estimate the areas under the curves in order to compare different multivariate analyses. We compared the performance of each otoacoustic emission (transient, distorsion product) using three different multivariate analyses for each ear, when multi-frequency gold standards were used. We demonstrated that all multivariate analyses provided high values of the area under the curve proving the performance of the otoacoustic emissions. Each otoacoustic emission test presented high

    Full Text Available Visual functions of children with hearing disability were evaluated in a school of Muscat, Oman in 2006. Two hundred and twenty-three children were tested for near vision, distant vision, contrast sensitivity, color vision, field of vision, motion perception and crowding. Profound and severe hearing loss was noted in 161 and 63 students respectively. Thirty-five (81% students with refractive error were using spectacles. Color vision and field of vision was defective in one student each. In 286 (64.1% eyes, contrast sensitivity was defective. Abnormal contrast sensitivity was not associated with the severity of hearing loss [RR = 1.04 (95% CI 0.91 to 1.29]. Children with hearing impairment should be assessed for visual functions. Refractive error and defect in contrast sensitivity were unusually high among these children. In addition to visual aids, we recommend environmental changes to improve illumination and contrast to improve the quality of life of such children with double disability.

    Permanent hearing impairment has a life-long impact on children and its early identification is important for language development. A newborn hearing screening (NHS) program has started in Okayama Prefecture, Japan, in 1999 to detect hearing impairment immediately after birth. We aim to examine the effect of this screening program on vocabulary development in pre-school children in a before and after comparative study design. A total of 107 5-year-old children who graduated from Okayama Kanariya Gakuen (an auditory center for hearing-impaired children) between 1998 and 2011 were enrolled in this study. The pre-NHS group (n=40) was defined as those who graduated between 1998 and 2003, while the post-NHS group (n=67) was defined as those who graduated between 2004 and 2011. The primary outcome was receptive vocabulary, which was assessed by the Picture Vocabulary Test [score vocabulary, or the number of productive words, which was assessed by an original checklist [vocabulary development and compared both groups. The adjusted Picture Vocabulary Test score and number of productive words were significantly higher (pvocabulary and 4.17 (95% confidence interval: 1.69-10.29) for productive vocabulary. The introduction of NHS in Okayama Prefecture significantly improved both receptive and productive vocabulary development in hearing-impaired children. Copyright © 2014 Elsevier Ireland Ltd.

    We examined the role of social frailty in the association between hearing problems and mild cognitive impairment (MCI), and investigated which cognitive impairment domains are most strongly involved. Participants were 4251 older adults (mean age 72.5 ± 5.2 years, 46.1% male) who met the study inclusion criteria. Hearing problems were measured using the Hearing Handicap Inventory for the Elderly. Social frailty was identified using responses to five questions. Participants were divided into four groups depending on the presence of social frailty and hearing problems: control, social frailty, hearing problem, and co-occurrence. We assessed memory, attention, executive function, and processing speed using the National Center for Geriatrics and Gerontology-Functional Assessment Tool. Participants were categorized into normal cognition, single- and multiple-domain MCI, depending on the number of impaired cognitive domains. Participants with multiple-domain MCI exhibited the highest odds ratios (OR) of the co-occurrence group (OR: 3.89, 95% confidence intervals [CI]: 1.96-7.72), followed by the social frailty (OR: 2.65, 95% CI: 1.49-4.67), and hearing problem (OR: 1.90, 95% CI: 1.08-3.34) groups, compared with the control group. However, single-domain MCI was not significantly associated with any group. Cognitive domain analysis revealed that impaired executive function and processing speed were associated with the co-occurrence, hearing problem, and social frailty groups, respectively. Social frailty and hearing problems were independently associated with multiple-domain MCI. Comorbid conditions were more strongly associated with multiple-domain MCI. Longitudinal studies are needed to elucidate the causal role of social frailty in the association between hearing impairment and MCI. Copyright © 2018 Elsevier B.V. All rights reserved.

    The aim of this study was to analyze infants diagnosed with sensorineural or conductive hearing deficit and to identify risk factors associated with these defects. A retrospective analysis of infants diagnosed with hearing deficit based on the database of the universal newborn hearing screening program and medical records of the patients. 27 935 infants were covered by the universal neonatal hearing screening program. 109 (0.39%) were diagnosed with hearing deficit and referred for treatment and rehabilitation. 56 (51.4%) children were diagnosed with conductive, 38 (34.9%) with sensorineural and 15 (13.8%) with mixed type of hearing deficit. Children with sensorineural hearing deficit more frequently suffered from hyperbilirubinemia (p conductive hearing loss were more frequently diagnosed with isolated craniofacial anomalies (p hearing deficit occurred almost 3 times more often bilaterally than unilaterally (p hearing deficit, the difference was not significant. In children with conductive and mixed type of hearing loss the impairment was mainly mild while among those with sensorineural hearing deficit in almost 45% it was severe and profound (p hearing screening test by means of otoacoustic emissions and the final diagnosis of hearing deficit we found that the highest agreement rate was observed in children with sensorineural hearing loss (p hearing deficit was similar in children with sensorineural, conductive and mixed type of hearing loss, only hyperbilirubinemia seemed to predispose to sensorineural hearing deficit and isolated craniofacial malformations seemed to be associated with conductive hearing loss. Sensorineural hearing deficit usually occurred bilaterally and was severe or profound, while conductive and mixed type of hearing deficit were most often of mild degree. Most children with the final diagnosis of sensorineural hearing deficit had positive result of hearing screening by means of otoacoustic emissions. Copyright © 2017 Elsevier B.V. All

    Individuals with stroke fall more often than age-matched controls. Although many focus on the multifactorial nature of falls, the fundamental problem is likely the ability for an individual to generate reactions to recover from a loss of balance. Stepping reactions to recover balance are particularly important to balance recovery, and individuals with stroke have difficulty executing these responses to prevent a fall following a loss of balance. The purpose of this study is to determine if characteristics of balance recovery steps are related to falls during inpatient stroke rehabilitation. We conducted a retrospective review of individuals with stroke attending inpatient rehabilitation (n = 136). Details of falls experienced during inpatient rehabilitation were obtained from incident reports, nursing notes, and patient interviews. Stepping reactions were evoked using a "release-from-lean" postural perturbation. Poisson regression was used to determine characteristics of stepping reactions that were related to increased fall frequency relative to length of stay. In all, 20 individuals experienced 29 falls during inpatient rehabilitation. The characteristics of stepping reactions significantly related to increased fall rates were increased frequency of external assistance to prevent a fall to the floor, increased frequency of no-step responses, increased frequency of step responses with inadequate foot clearance, and delayed time to initiate stepping responses. Impaired control of balance recovery steps is related to increased fall rates during inpatient stroke rehabilitation. This study informs the specific features of stepping reactions that can be targeted with physiotherapy intervention during inpatient rehabilitation to improve dynamic stability control and potentially prevent falls.

    The objective of the study was to translate and culturally adapt to Portuguese the TELEGRAM instrument and to evaluate its effectiveness in adults with hearing impairment using hearing aids. The TELEGRAM was translated into the Portuguese language, reviewed for grammatical and idiomatic equivalences (reverse translations) and linguistic and cultural adaptations. After translation, the TELEGRAM was applied to 20 individuals with hearing impairment. A descriptive analysis of the results was performed. After the grammatical and idiomatic equivalence, the replacement of one term/item was suggested, which was modified and adapted to the Brazilian context. In general, the questions of the instrument were considered easy to understand. Among the categories assessed, individuals with hearing loss had greater difficulty using the telephone and in activities such as attending church gatherings, parties, or in situations of noisy environments, distance and reverberation. The TELEGRAM translated into Brazilian Portuguese proved to be an easily applicable tool in population studies and effective to assess which are the main situations where individuals with hearing impairment have greater difficulty in communication, reinforcing the importance of hearing rehabilitation and assistive technology to minimize these difficulties.

    Full Text Available TRPML3, a member of the transient receptor potential (TRP family, is an inwardly rectifying, non-selective Ca2+-permeable cation channel that is regulated by extracytosolic Na+ and H+ and can be activated by a variety of small molecules. The severe auditory and vestibular phenotype of the TRPML3(A419P varitint-waddler mutation made this protein particularly interesting for inner ear biology. To elucidate the physiological role of murine TRPML3, we conditionally inactivated Trpml3 in mice. Surprisingly, lack of functional TRPML3 did not lead to circling behavior, balance impairment or hearing loss.

    2008-01-01

    The study was carried out on children born over a 10 year period from 1997 to 2006 in Kobe city and referred to our center for specialist audiological assessment. A total of 107 cases had a bilateral sensorineural hearing impairment averaging 25 dB or over in the better hearing ear during the study period. To ascertain causes of sensorineural hearing impairment, full medical histories were obtained with detailed family history relevant to hearing impairment and perinatal course for adverse etiological factors. The children were investigated for possible congenital infection and chromosomal anomalies. Children with positive family history of deafness in parents or siblings constituted 11.2% of cases (genetic group). Other etiological groups showed the following distribution: syndromal group 5.6%; inner ear anomalies 5.6%; perinatal group 13.1%; congenital infection 11.2%; chromosomal anomalies 16.8%; multiple congenital anomalies 5.6%; causes unknown 30.9%. The high incidence of causes unknown indicates that steps should be taken to yield a diagnosis. The total number of children born in Kobe city was 117,896 during the period from 1997 to 2005, which gave a prevalence rate of hearing impairment of 0.87/1,000 births. Newborn hearing screening identified many children earlier and also provide the opportunity to finetune the evaluation. (author)

  8. Effects of Varying Reverberation on Music Perception for Young Normal-Hearing and Old Hearing-Impaired Listeners.

    Reverberation enhances music perception and is one of the most important acoustic factors in auditorium design. However, previous research on reverberant music perception has focused on young normal-hearing (YNH) listeners. Old hearing-impaired (OHI) listeners have degraded spatial auditory processing; therefore, they may perceive reverberant music differently. Two experiments were conducted examining the effects of varying reverberation on music perception for YNH and OHI listeners. Experiment 1 examined whether YNH listeners and OHI listeners prefer different amounts of reverberation for classical music listening. Symphonic excerpts were processed at a range of reverberation times using a point-source simulation. Listeners performed a paired-comparisons task in which they heard two excerpts with different reverberation times, and they indicated which they preferred. The YNH group preferred a reverberation time of 2.5 s; however, the OHI group did not demonstrate any significant preference. Experiment 2 examined whether OHI listeners are less sensitive to (e, less able to discriminate) differences in reverberation time than YNH listeners. YNH and OHI participants listened to pairs of music excerpts and indicated whether they perceived the same or different amount of reverberation. Results indicated that the ability of both groups to detect differences in reverberation time improved with increasing reverberation time difference. However, discrimination was poorer for the OHI group than for the YNH group. This suggests that OHI listeners are less sensitive to differences in reverberation when listening to music than YNH listeners, which might explain the lack of group reverberation time preferences of the OHI group.

    Hearing and vision impairment were examined across several health-related outcomes and across a set of quality indicators (QIs) in home care clients with both vision and hearing loss (or dual sensory impairment [DSI]). Data collected using the Resident Assessment Instrument for Home Care (RAI-HC) were analyzed in a sample of older home care clients. The QIs represent the proportion of clients experiencing negative outcomes (e.g., falls, social isolation). The average age of clients was 82.8 years ( SD = 7.9), 20.5% had DSI and 8.5% had a diagnosis of Alzheimer's disease (AD). Clients with DSI were more likely to have a diagnosis of dementia (not AD), have functional impairments, report loneliness, and have higher rates across 20 of the 22 QIs, including communication difficulty and cognitive decline. Clients with highly impaired hearing, and any visual impairment, had the highest QI rates. Individuals with DSI experience higher rates of adverse events across many health-related outcomes and QIs. Understanding the unique contribution of hearing and vision in this group can promote optimal quality of care.

    This paper discuss on the dimensions that has been derived for the hearing-impaired mobile applications usability model. General usability model consist of general dimension for evaluating mobile application however requirements for the hearing-impaired are overlooked and often scanted. This led towards mobile application developed for the hearing-impaired are left unused. It is also apparent that these usability models do not consider accessibility dimensions according to the requirement of the special users. This complicates the work of usability practitioners as well as academician that practices research usability when application are developed for the specific user needs. To overcome this issue, dimension chosen for the hearing-impaired are ensured to be align with the real need of the hearing-impaired mobile application. Besides literature studies, requirements for the hearing-impaired mobile application have been identified through interview conducted with hearing-impaired mobile application users that were recorded as video outputs and analyzed using Nvivo. Finally total of 6 out of 15 dimensions gathered are chosen for the proposed model and presented.

    Full Text Available Introduction: Newborn hearing screening leads to the early detection of hearing impairment. The aim of screening is to decrease or remove the effect of hearing impairment on development of speech and language by timely diagnosis and effective treatment. A number of risk factors lead to delayed start of decreased hearing ability including: 1. Congenital infection with cytomegalovirus  (CMV virus, 2. Meningitis, 3. Mumps, 4. Positive family history, 5. Head trauma, 6. Chemotherapy, 7. Syndrome pertaining to delayed start of decreased hearing. Unfortunately, lack of attention to early diagnosis of hearing impairment is becoming a general health problem. No research has yet been carried out relating to the knowledge of pediatricians on this issue, particularly the importance of hearing impairment and hearing screening. The aim of this study was to determine the attitude to newborn hearing screening among pediatricians.   Materials and Methods: This cross-sectional, descriptive-analytic study was conducted in Isfahan in 2012 among 300 pediatricians and final-year pediatric residents. An adjusted 22-question version of the Early Hearing Detection and Intervention (EHDI questionnaire was used to collect data. The validity and reliability of the EHDI questionnaire was previously demonstrated by Boys Town National Research Hospital and its Farsi translated version was validated by the EDC Center at the Isfahan University of Medical Sciences.   Results: In our study, 83% of pediatricians agreed on the importance of hearing impairment screening for all infants. However 65% were not aware of special needs for hearing-impaired patients.   Conclusion:  Newborn hearing impairment and deafness screening is important, irrespective of the costs, and lack of timely diagnosis results in both individual and social consequences. The majority of physicians use textbooks to gain information about hearing screening, but recognize that this is insufficient. Although

    The effects of hearing impairment on the perception of binaural-pitch stimuli were investigated. Several experiments were performed with normal-hearing and hearing-impaired listeners, including detection and discrimination of binaural pitch, and melody recognition using different types of binaural...... pitches. For the normal-hearing listeners, all types of binaural pitches could be perceived immediately and were musical. The hearing-impaired listeners could be divided into three groups based on their results: (a) some perceived all types of binaural pitches, but with decreased salience or musicality...... compared to normal-hearing listeners; (b) some could only perceive the strongest pitch types; (c) some were unable to perceive any binaural pitch at all. The performance of the listeners was not correlated with audibility. Additional experiments investigated the correlation between performance in binaural...

    To determine the factors contributing towards hearing impairment in patients with cleft lip/palate. A prospective analysis was conducted on 173 patients (346 ears) with cleft lip and palate (CL/P) who presented to the combined cleft clinic at University Malaya Medical Centre (UMMC) over 12 months. The patients' hearing status was determined using otoacoustic emission (OAE), pure tone audiometry (PTA) and auditory brainstem response (ABR). These results were analysed against several parameters, which included age, gender, race, types of cleft pathology, impact and timing of repair surgery. The patients' age ranged from 1-26 years old. They comprised 30% with unilateral cleft lip and palate (UCLP), 28% with bilateral cleft lip and palate (BCLP), 28% with isolated cleft palate (ICP) and 14% with isolated cleft lip (ICL). Majority of the patients (68.2%) had normal otoscopic findings. Out of the 346 ears, 241 ears (70%) ears had passed the hearing tests. There was no significant relationship between patients' gender and ethnicity with their hearing status. The types of cleft pathology significantly influenced the outcome of PTA and ABR screening results (p cleft groups and the outcome of hearing tests. However, hearing improvement occurred when palatal repair was performed at the age of cleft patients had normal hearing (70%). Hearing threshold varied significantly between the different types of cleft pathology. Surgery conferred no significant impact on the hearing outcome unless surgery was performed at the age of <1 year old. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    The aim of the study was to evaluate the neck torsion test in objective examinations of patients with vertigo and/or hearing loss. The study was conducted in 100 patients, including 54 women and 46 men aged 17-79 years, who were divided into two groups: I - 50 patients, including 30 women and 20 men aged 17-79 years (mean age 49.92 years) with dizziness and/or hearing impairments, and confirmed asymmetry of intracranial vessels, II - 50 patients - the control group, including 24 women and 26 men aged 20-71 years without dizziness and/or hearing disorders and without disturbance in the construction of intracranial vessels. For each patient, the following tests were carried out: subjective, objective otorhinolaryngological, Doppler ultrasound specifying the diameter of vertebral and carotid arteries and the velocity of blood flow in these vessels, audiological diagnostics, including the examination of latency of waves I, III, V of the auditory evoked potentials of the brain stem, otoneurological diagnostics with used the neck torsion test. It appears from the analysis of the material presented that the application of the neck torsion test in the Doppler ultrasound results in the fact that the difference in the mean systolic velocity of blood flow in vertebral artery is higher on the side opposite to the turning of the neck, and the increase in the average diastolic blood flow velocity in the vertebral artery on the side of the test being performed and its reduction on the opposite side in the study group, when compared to the control group. The value of the wave I, II, V latency in the ABR test during the neck torsion test is extended more in the study group than in the controls, on the side of the performed test. The performed neck torsion test in the VNG test increases the occurrence of both, square waves and nystagmus (much higher in the study group than in the controls).

    2000-03-01

    For a report on the stress experiences of parents with hearing-impaired children in Germany, 317 parents completed a survey on how their families communicate and socialize, among other issues. The report focuses on how contacts with other parents and with hearing-impaired adults affect stress experiences, in the context of the child's hearing status and the means of communication. Parents who frequently meet with other parents show evidence of a warm, accepting, trusting relationship with their child. Parents who have many contacts with hearing-impaired adults show evidence of a strong sense of competence in regard to their child's upbringing. The findings confirm the implication found in most reports describing empirical studies. Social support is to be regarded as a cornerstone of psychosocial intervention and has to play as great a role as possible in institutional programs.

  19. Phenotypic and molecular assessment of seven patients with 6p25 deletion syndrome: Relevance to ocular dysgenesis and hearing impairment

    Directory of Open Access Journals (Sweden)

    Ritch Robert

    2004-06-01

    Full Text Available Abstract Background Thirty-nine patients have been described with deletions involving chromosome 6p25. However, relatively few of these deletions have had molecular characterization. Common phenotypes of 6p25 deletion syndrome patients include hydrocephalus, hearing loss, and ocular, craniofacial, skeletal, cardiac, and renal malformations. Molecular characterization of deletions can identify genes that are responsible for these phenotypes. Methods We report the clinical phenotype of seven patients with terminal deletions of chromosome 6p25 and compare them to previously reported patients. Molecular characterization of the deletions was performed using polymorphic marker analysis to determine the extents of the deletions in these seven 6p25 deletion syndrome patients. Results Our results, and previous data, show that ocular dysgenesis and hearing impairment are the two most highly penetrant phenotypes of the 6p25 deletion syndrome. While deletion of the forkhead box C1 gene (FOXC1 probably underlies the ocular dysgenesis, no gene in this region is known to be involved in hearing impairment. Conclusions Ocular dysgenesis and hearing impairment are the two most common phenotypes of 6p25 deletion syndrome. We conclude that a locus for dominant hearing loss is present at 6p25 and that this locus is restricted to a region distal to D6S1617. Molecular characterization of more 6p25 deletion patients will aid in refinement of this locus and the identification of a gene involved in dominant hearing loss.

  20. Peripheral auditory processing and speech reception in impaired hearing

    DEFF Research Database (Denmark)

    Strelcyk, Olaf

    One of the most common complaints of people with impaired hearing concerns their difficulty with understanding speech. Particularly in the presence of background noise, hearing-impaired people often encounter great difficulties with speech communication. In most cases, the problem persists even...... if reduced audibility has been compensated for by hearing aids. It has been hypothesized that part of the difficulty arises from changes in the perception of sounds that are well above hearing threshold, such as reduced frequency selectivity and deficits in the processing of temporal fine structure (TFS......) at the output of the inner-ear (cochlear) filters. The purpose of this work was to investigate these aspects in detail. One chapter studies relations between frequency selectivity, TFS processing, and speech reception in listeners with normal and impaired hearing, using behavioral listening experiments. While...

The GINKO study examines the impact of laws on the integration of hard-of-hearing and deaf people as well as people who have become deaf as adults, focusing on communication and organizations; this project was funded by the German Federal Ministry for Labour and Social Affairs (BMAS). In the GINKO study, conducted in cooperation with the German Association of the Hard of Hearing and the German Association of the Deaf, a standardised questionnaire with questions about the workplace was administered to employed people with hearing impairments. The questionnaire was administered on paper and was also available online accompanied by sign language videos. The University of Cologne study in North Rhine-Westphalia examined the service situation of hard-of-hearing, deaf and deaf-blind people through face-to-face interviews and government statistics. The results of the nationwide GINKO study show that hearing-impaired people in North Rhine-Westphalia draw on assistive services in employment more often than hearing-impaired people in the rest of Germany. The study found statistically significant differences in the categories of "maintenance and development of professional knowledge and skills" and "psychosocial support in conflict situations resulting from disability". One reason for the more positive evaluations of the participants in North Rhine-Westphalia as compared to other regions in Germany could be the particular network of support services in that state. However, the overall positive results from North Rhine-Westphalia should not obscure the fact that a majority of participants in

    Full Text Available Introduction: In recent years, music has been employed in many intervention and rehabilitation program to enhance cognitive abilities in patients. Numerous researches show that music therapy can help improving language skills in patients including hearing impaired. In this study, a new method of music training is introduced based on principles of neuroscience and capabilities of Persian language to optimize language development in deaf children after implantation.    Materials and Methods: The candidate children are classified in three groups according to their hearing age and language development. The music training program is established and centered on four principles, as follows: hearing and listening to music (with special attention to boost hearing, singing, rhythmic movements with music and playing musical instruments.   Results: Recently much research has demonstrated that even after cochlear implant operation, a child cannot acquire language to the same level of detail as a normal child. As a result of this study music could compensate this developmental delay .It is known that the greater the area of the brain that is activated, the more synaptic learning and plasticity changes occur in that specific area. According to the principles of neural plasticity, music could improve language skills by activating the same areas for language processing in the brain.   Conclusion:  In conclusion, the effects of music on the human brain seem to be very promising and therapeutic in various types of disorders and conditions, including cochlear implantation.

    The aim of this study was to assess the main ear malformations, hearing loss and auditory rehabilitation in children with Treacher Collins syndrome. We performed a retrospective study of 9 children with Treacher Collins syndrome treated in a central hospital between January 2003 and January 2013. This study showed a high incidence of malformations of the outer and middle ear, such as microtia, atresia or stenosis of the external auditory canal, hypoplastic middle ear cavity, dysmorphic or missing ossicular chain. Most patients had bilateral hearing loss of moderate or high degree. In the individuals studied, there was functional improvement in patients with bone-anchored hearing aids in relation to conventional hearing aids by bone conduction. Treacher Collins syndrome is characterized by bilateral malformations of the outer and middle ear. Hearing rehabilitation in these children is of utmost importance, and bone-anchored hearing aids is the method of choice.

    The objective of this study was to compare the timing of hearing aid (HA) acquisition between adults in rural and urban communities. We hypothesized that time of acquisition of HA after onset of hearing loss is greater in rural adults compared with urban adults. Secondary objectives included assessment of socioeconomic/educational status and impact of hearing loss and hearing rehabilitation of urban and rural HA recipients. Cross-sectional questionnaire survey. We assessed demographics, timing of HA fitting from onset of hearing loss, and impact of hearing impairment in 336 adult HA recipients (273 urban, 63 rural) from a tertiary referral center. Amplification benefit was assessed using the International Outcome Inventory for Hearing Aids (IOI). The time to HA acquisition was greater for rural participants compared to urban participants (19.1 vs. 25.7 years, P = 0.024) for those with untreated hearing loss for at least 8 years. Age at hearing loss onset was correlated with time to HA acquisition (P = -0.54, P hearing specialists (68 vs. 32 minutes, P Hearing impairment caused job performance difficulty in 60% of all participants. Rural adults are at risk for delayed HA acquisition, which may be related to distance to hearing specialists. Further research is indicated to investigate barriers to care and expand access for vulnerable populations. 4.

    To determine whether hearing loss is associated with incident physician-diagnosed dementia in a representative sample. Retrospective cohort study. English Longitudinal Study of Ageing. Adults aged 50 and older. Cross-sectional associations between self-reported (n = 7,865) and objective hearing measures (n = 6,902) and dementia were examined using multinomial-logistic regression. The longitudinal association between self-reported hearing at Wave 2 (2004/05) and cumulative physician-diagnosed dementia up to Wave 7 (2014/15) was modelled using Cox proportional hazards regression. After adjustment for potential confounders, in cross-sectional analysis, participants who had self-reported or objective moderate and poor hearing were more likely to have a dementia diagnosis than those with normal hearing (self-reported: odds ratio OR = 1.6, 95% CI = 1.1-2.4 moderate hearing; OR = 2.6, 95% CI = 1.7-3.9 poor hearing, objective: OR = 1.6, 95% CI = 1.0-2.8 moderate hearing; OR = 4.4, 95% CI = 1.9-9.9 poor hearing). Longitudinally, the hazard of developing dementia was 1.4 (95% CI = 1.0-1.9) times as high in individuals who reported moderate hearing and 1.6 (95% CI = 1.1-2.0) times as high in those who reported poor hearing. Older adults with hearing loss are at greater risk of dementia than those with normal hearing. These findings are consistent with the rationale that correction of hearing loss could help delay the onset of dementia, or that hearing loss itself could serve as a risk indicator for cognitive decline. © 2017, The Authors.

    2016-04-06

    Hippotherapy is the use of equine movement in physical, occupational, or speech therapy in order to obtain functional improvements in patients. Studies show improvement in motor function and sensory processing for patients with a variety of neuromuscular disabilities, developmental disorders, or skeletal impairments as a result of using hippotherapy. The primary objective of this study is to identify the pervasiveness of hippotherapy in Southern California, and any factors that impair its utilization. One hundred and fifty-two rehabilitation centers in the Southern California counties of Los Angeles, San Diego, Orange, Riverside, San Bernardino, San Diego, San Luis Obispo, Santa Barbara, Ventura, and Kern County were identified, and surveyed to ascertain if hippotherapy is utilized, and if not, why not. Through a review of forty facilities that responded to our inquiry, our study indicates that the majority of rehabilitation centers are familiar with hippotherapy, however, only seven have reported that hippotherapy is indeed available as an option in therapy at their centers. It is concluded that hippotherapy, used in a broad based array of physical and sensory disorders, is limited in its ability to be utilized, primarily due to remuneration issues.

    Purpose: Frequency fluctuations in human voices can usually be described as coherent frequency modulation (FM). As listeners with hearing impairment (HI listeners) are typically less sensitive to FM than listeners with normal hearing (NH listeners), this study investigated whether hearing loss...... affects the perception of a sung vowel based on FM cues. Method: Vibrato maps were obtained in 14 NH and 12 HI listeners with different degrees of musical experience. The FM rate and FM excursion of a synthesized vowel, to which coherent FM was applied, were adjusted until a singing voice emerged. Results......: In NH listeners, adding FM to the steady vowel components produced perception of a singing voice for FM rates between 4.1 and 7.5 Hz and FM excursions between 17 and 83 cents on average. In contrast, HI listeners showed substantially broader vibrato maps. Individual differences in map boundaries were...

    well as to an elderly group of listeners with sensorineural hearing loss in the speech-shaped noise (Experiment 3). The results of three experiments verified predictions of NAM in both normal hearing and hearing-impaired listeners. In each experiment, words from low density neighborhoods were recognized more accurately than those from high density neighborhoods. The presence of high frequency neighbors (average neighborhood frequency) produced poorer recognition performance than comparable conditions with low frequency neighbors. Word frequency was found to have a highly significant effect on word recognition. Lexical conditions with high word frequencies produced higher performance scores than conditions with low frequency words. The results supported the basic tenets of NAM theory and identified both neighborhood structural properties and word frequency as significant lexical factors affecting word recognition when listening in noise and "in quiet." The results of the third experiment permit extension of NAM theory to individuals with sensorineural hearing loss. Future development of speech recognition tests should allow for the effects of higher level cognitive (lexical) factors on lower level phonemic processing.

    Full Text Available Objective: To describe stroke survivors’ experiences of sensory impairment in the upper limb, the influence of such impairment on daily life, coping strategies used, and sensory training for the affected hand. Design: A qualitative study with a content analysis approach. Subjects: Fifteen post-stroke patients interviewed individually. Results: Five categories emerged from the data: “Changed and varied perception of the sensation”; “Affected movement control”; “Problems using the hand in daily life”; “Various strategies to cope with upper limb disability”; and “Lack of sensory training”. Numbness and tingling, changes in temperature sensitivity, and increased sensitivity to touch and pain were reported. Many subjects had difficulty adjusting their grip force and performing movements with precision. It was problematic and mentally fatiguing managing personal care and carrying out household and leisure activities. Practical adaptations, compensation with vision, increased concentration, and use of the less affected hand were strategies used to overcome difficulties. Despite their problems very few subjects had received any specific sensory training for the hand. Conclusion: Stroke survivors perceive that sensory impairment of the upper limb has a highly negative impact on daily life, but specific rehabilitation for the upper limb is lacking. These findings imply that the clinical management of upper limb sensory impairment after stroke requires more attention.

    Cognitive rehabilitation has been developed to improve quality of life, activities of daily living and mood for people with cognitive impairment, but the voice of people with cognitive impairment has been underrepresented. This study aimed to understand the experience of people living with cognitive impairment, as well as their caregivers who took part in a cognitive rehabilitation intervention programme. Twelve individuals with cognitive impairment and 15 caregivers participated in individual qualitative interviews. The interview data were analysed in three steps: 1) familiarisation of the transcripts; 2) identification of themes; 3) re-interpretation, refinement and integration of themes with methodological auditors. Both participants living with cognitive impairment and caregivers valued the comfortable environment with friendly, caring and supportive group leaders who taught practical tips and strategies. The participants living with cognitive impairment enjoyed socialising with like others. Caregivers benefited from learning about memory problems and sharing their challenges with other caregivers. The participants living with cognitive impairment emphasised the benefits of relational and practical aspects, whereas the caregivers valued the informational and emotional support. In conclusion, both participants living with cognitive impairment and caregivers found the cognitive rehabilitation group useful.

    participants, risk ratio (RR) 1.06, 95% CI 1.00 to 1.12). However, there was no evidence of a statistically or clinically significant effect on daily hours of hearing aid use over the long term, or the short to medium term. No studies of this type investigated adverse effects. There was no evidence of an effect on quality of life over the long term, or short to medium term. These combined interventions reduced hearing handicap in the short to medium term (15 studies, 728 participants; standardised mean difference (SMD) -0.26, 95% CI -0.48 to -0.04). This represents a small-moderate effect size but there is no evidence of a statistically significant effect over the long term. There was evidence of a statistically, but not clinically, significant effect on long-term hearing aid benefit (two studies, 69 participants, MD 0.30, 95% CI 0.02 to 0.58 (1 to 5 scale)), but no evidence of an effect over the short to medium term. There was evidence of a statistically, but not clinically, significant effect on the use of verbal communication strategies in the short term (four studies, 223 participants, MD 0.45, 95% CI 0.15 to 0.74 (0 to 5 scale)), but not the long term. Our confidence in the quality of this evidence was low or very low.We found no studies that assessed the effect of other CCM interventions (decision support, the clinical information system, community resources or health system changes). There is some low to very low quality evidence to support the use of self-management support and complex interventions combining self-management support and delivery system design in adult auditory rehabilitation. However, effect sizes are small. The range of interventions that have been tested is relatively limited. Future research should prioritise: long-term outcome assessment; development of a core outcome set for adult auditory rehabilitation; and study designs and outcome measures that are powered to detect incremental effects of rehabilitative healthcare system changes.

    2001-04-01

    The present study reports a detailed analysis of written and spoken language samples of Hebrew-speaking children aged 11-13 years who are deaf. It focuses on the description of various grammatical deviations in the two modalities. Participants were 13 students with hearing impairments (HI) attending special classrooms integrated into two elementary schools in Tel Aviv, Israel, and 9 students with normal hearing (NH) in regular classes in these same schools. Spoken and written language samples were collected from all participants using the same five preplanned elicitation probes. Students with HI were found to display significantly more grammatical deviations than their NH peers in both their spoken and written language samples. Most importantly, between-modality differences were noted. The participants with HI exhibited significantly more grammatical deviations in their written language samples than in their spoken samples. However, the distribution of grammatical deviations across categories was similar in the two modalities. The most common grammatical deviations in order of their frequency were failure to supply obligatory morphological markers, failure to mark grammatical agreement, and the omission of a major syntactic constituent in a sentence. Word order violations were rarely recorded in the Hebrew samples. Performance differences in the two modalities encourage clinicians and teachers to facilitate target linguistic forms in diverse communication contexts. Furthermore, the identification of linguistic targets for intervention must be based on the unique grammatical structure of the target language.

    A major complaint of individuals with normal hearing and hearing impairments is a reduced ability to understand speech in a noisy environment. This paper describes the concept of adaptive noise cancelling for removing noise from corrupted speech signals. Application of adaptive digital signal processing has long been known and is described from a historical as well as technical perspective. The Widrow-Hoff LMS (least mean square) algorithm developed in 1959 forms the introduction to modern adaptive signal processing. This method uses a "primary" input which consists of the desired speech signal corrupted with noise and a second "reference" signal which is used to estimate the primary noise signal. By subtracting the adaptively filtered estimate of the noise, the desired speech signal is obtained. Recent developments in the field as they relate to noise cancellation are described. These developments include more computationally efficient algorithms as well as algorithms that exhibit improved learning performance. A second method for removing noise from speech, for use when no independent reference for the noise exists, is referred to as single channel noise suppression. Both adaptive and spectral subtraction techniques have been applied to this problem--often with the result of decreased speech intelligibility. Current techniques applied to this problem are described, including signal processing techniques that offer promise in the noise suppression application.

    2012-12-01

    Full Text Available Purpose: Inclusion of children with disabilities in mainstream classrooms has become the focus of extensive research in education. It has both academic and social benefits for all students, such as providing opportunities for communication and social interaction. The evaluation of teachers’ attitudes towards inclusion appears to be a good method to determine the success of the programme. Although this has been widely researched in many countries, the available evidence is not consistent. This study was undertaken in the state of Andhra Pradesh in India, to measure and compare teachers’ attitudes towards the inclusion of children with hearing impairment in schools.Method: A questionnaire developed by Giles and Tanner (1995 measuring three domains - (1 effective strategies for meeting the needs of all students, (2 the support for educational change in their district, and (3 inclusive education - was modified in keeping with cultural and geographical variations and used as the test tool. A hundred teachers of various Government and non-Government schools in 2 districts of Andhra Pradesh, India, participated in the study.Results: Higher scores on domain 1 indicate that teachers feel effective strategies to benefit students with disabilities should be implemented in schools. The results also indicate that most teachers are agreeable to the inclusion of students with disabilities in their classrooms. Significant difference in attitudes was observed, based on the teachers’ qualifications, teaching experience, gender, level of teaching and management.Conclusion: The study concludes that there is a need for intervention to foster more positive attitudes among teachers, if the implementation of inclusive education is to succeed. It also has implications for the framing of laws and policies for children with hearing impairments.doi: 10.5463/dcid.v23i3.117

    We sought to examine the contribution of visual cues in audiovisual identification of consonants and vowels-in terms of isolation points (the shortest time required for correct identification of a speech stimulus), accuracy, and cognitive demands-in listeners with hearing impairment using hearing aids. The study comprised 199 participants with hearing impairment (mean age = 61.1 years) with bilateral, symmetrical, mild-to-severe sensorineural hearing loss. Gated Swedish consonants and vowels were presented aurally and audiovisually to participants. Linear amplification was adjusted for each participant to assure audibility. The reading span test was used to measure participants' working memory capacity. Audiovisual presentation resulted in shortened isolation points and improved accuracy for consonants and vowels relative to auditory-only presentation. This benefit was more evident for consonants than vowels. In addition, correlations and subsequent analyses revealed that listeners with higher scores on the reading span test identified both consonants and vowels earlier in auditory-only presentation, but only vowels (not consonants) in audiovisual presentation. Consonants and vowels differed in terms of the benefits afforded from their associative visual cues, as indicated by the degree of audiovisual benefit and reduction in cognitive demands linked to the identification of consonants and vowels presented audiovisually.

    Full Text Available Objective: This study was a basic investigation of the ability of concurrent speech segregation in hearing impaired children. Concurrent segregation is one of the fundamental components of auditory scene analysis and plays an important role in speech perception. In the present study, we compared auditory late responses or ALRs between hearing impaired and normal children. Materials & Methods: Auditory late potentials in response to 12 double vowels were recorded in 10 children with moderate to severe sensory neural hearing loss and 10 normal children. Double vowels (pairs of synthetic vowels were presented concurrently and binaurally. Fundamental frequency (F0 of these vowels and the size of the difference in F0 between vowels was 100 Hz and 0.5 semitones respectively. Results: Comparing N1-P2 amplitude showed statistically significant difference in some stimuli between hearing impaired and normal children (P<0.05. This complex indexing the vowel change detection and reflecting central auditory speech representation without active client participation was decreased in hearing impaired children. Conclusion: This study showed problems in concurrent speech segregation in hearing impaired children evidenced by ALRs. This information indicated deficiencies in bottom-up processing of speech characteristics based on F0 and its differences in these children.

The study, conducted by trained staff on both groups was done by filling up questionnaires focused on the job and educational level preferences of students. The required education levels for preferred jobs were considered as two groups: the first group required an education of a minimum of 11 years in order to become doctors, nurses, teachers etc. The second group did not require any education or required an education of less than 11 years in order to become shoe painters, drivers, ironers, grocers etc. Logistic regression analyses were used for the statistical analyses. Results: It was found that several factors influence the required education levels for the preferred jobs: students who were attending the hearing impaired school and were male were more likely to prefer less than 11 years educational level job compared to the other group. There was no association between the required educational levels for the preferred jobs of the students and the class, maternal age, employment status or education, or of the paternal age, employment status or education. Considering only the students with hearing impairment, male students more frequently prefer less than 11 years educational jobs than females. Similar results were also seen in the group of students without hearing impairment. Conclusions: The importance of career training and counseling

    Since amplified music gained widespread popularity, there has been community concern that leisure-noise exposure may cause hearing loss in adolescents and young adults who would otherwise be free from hearing impairment. Repeated exposure to personal stereo players and music events (e.g., nightclubbing, rock concerts, and music festivals) are of particular concern. The same attention has not been paid to leisure-noise exposure risks for young people with hearing impairment (either present from birth or acquired before adulthood). This article reports on the analysis of a subset of data (leisure participation measures) collected during a large, two-phase study of the hearing health, attitudes, and behaviors of 11- to 35-yr-old Australians conducted by the National Acoustic Laboratories (n = 1,667 hearing threshold level datasets analyzed). The overall aim of the two-phase study was to determine whether a relationship between leisure-noise exposure and hearing loss exists. In the current study, the leisure activity profiles and accumulated ("whole-of-life") noise exposures of young people with (1) hearing impairment and (2) with normal hearing were compared. Cross-sectional cohort study. Hearing impaired (HI) group, n = 125; normal (nonimpaired) hearing (NH) group, n = 296, analyzed in two age-based subsets: adolescents (13- to 17-yr-olds) and young adults (18- to 24-yr-olds). Participant survey. The χ² test was used to identify systematic differences between the leisure profiles and exposure estimates of the HI and NH groups. Whole-of-life noise exposure was estimated by adapting techniques described in ISO 1999. For adolescents, leisure profiles were similar for the two groups and few individuals exceeded the stated risk criterion. For young adults, participation was significantly lower for the HI group for 7 out of 18 leisure activities surveyed. Activity diversity and whole-of-life exposure were also significantly lower for the HI group young adults. A

    Full Text Available Following the unilateral declaration of independence in 2008, Republic of Kosovo initiated a thorough reconstruction process in all areas including education. Conducted within the scope of a protocol signed by Kosovo Ministry of Education and Anadolu University as a reflection of this reform era, this research aims to identify the problems and needs of children with hearing impairment in Kosovo through analyzing the regulations in diagnosis, assessment, and education of the hearing impaired. Including 92 participants and employing simultaneous variation design, one of the mixed methods, this study has utilized questionnaires administered to the parents (n = 34 and teachers (n = 28 of the children with hearing impairment, and the healthcare personnel (n = 20 working with these kids. In addition, semi-structured interviews have been held with a group of parents (n = 4 and teachers (n = 6. Descriptive analysis of semi-structured interviews—a qualitative technique—and questionnaires—a quantitative tool—has revealed major problems in two fundamental areas: (a diagnosis, assessment, and intervention (b and educational arrangements. Primary issues in the first group are diagnosis and assessment of the impairment, use of hearing aids, support services for the family after the diagnosis, and prominent deficiencies and inadequacies in pre-school education. On the other hand, troubles in the second group include the mismatch of communicative approaches preferred by families and applied by schools and incredibility of the number and quality of teachers, the physical infrastructure of schools, instructional planning and application, and the inclusion practice. This research has clearly depicted that serious structural modifications regarding the problem areas have to be launched immediately.Keywords: Hearing-impaired children, Republic of Kosovo, diagnosis-assessment, educational arrangements.Tanıdan Eğitime Kosova Cumhuriyeti’nde

    The present single case study describes the rehabilitation of an acquired impairment of multiplication fact retrieval. In addition to a conventional drill approach, one set of problems was preceded by auditory cues while the other half was not. After extensive repetition, non-specific improvements could be observed for all trained problems (e.g., 3 * 7) as well as for their non-trained complementary problems (e.g., 7 * 3). Beyond this general improvement, specific therapy effects were found for problems trained with auditory cues. These specific effects were attributed to an involvement of implicit memory systems and/or attentional processes during training. Thus, the present results demonstrate that cues in the training of arithmetic facts do not have to be visual to be effective.

  15. Discrimination task reveals differences in neural bases of tinnitus and hearing impairment.

    Full Text Available We investigated auditory perception and cognitive processing in individuals with chronic tinnitus or hearing loss using functional magnetic resonance imaging (fMRI. Our participants belonged to one of three groups: bilateral hearing loss and tinnitus (TIN, bilateral hearing loss without tinnitus (HL, and normal hearing without tinnitus (NH. We employed pure tones and frequency-modulated sweeps as stimuli in two tasks: passive listening and active discrimination. All subjects had normal hearing through 2 kHz and all stimuli were low-pass filtered at 2 kHz so that all participants could hear them equally well. Performance was similar among all three groups for the discrimination task. In all participants, a distributed set of brain regions including the primary and non-primary auditory cortices showed greater response for both tasks compared to rest. Comparing the groups directly, we found decreased activation in the parietal and frontal lobes in the participants with tinnitus compared to the HL group and decreased response in the frontal lobes relative to the NH group. Additionally, the HL subjects exhibited increased response in the anterior cingulate relative to the NH group. Our results suggest that a differential engagement of a putative auditory attention and short-term memory network, comprising regions in the frontal, parietal and temporal cortices and the anterior cingulate, may represent a key difference in the neural bases of chronic tinnitus accompanied by hearing loss relative to hearing loss alone.

  16. Severe hearing impairment among military veterans--United States, 2010.

    A substantial proportion of hearing loss in the United States is attributable to employment-related exposure to noise. Among military veterans, the most common service-connected disabilities are hearing impairments, suggesting that occupational noise exposure during military service might cause more veterans to have hearing loss than nonveterans. However, a recent analysis of data from the 1993-1995 Epidemiology of Hearing Loss Study did not find significant differences between the two groups. To further investigate hearing loss among veterans, specifically the prevalence of severe hearing impairment (SHI), data from the 2010 Annual Social and Economic Supplement (ASEC) to the Current Population Survey (CPS) were analyzed. This report describes the results of those analyses, which indicated that the prevalence of SHI among veterans was significantly greater than among nonveterans. Veterans were 30% more likely to have SHI than nonveterans after adjusting for age and current occupation, and veterans who served in the United States or overseas during September 2001-March 2010, the era of overseas contingency operations (including Operations Enduring Freedom and Iraqi Freedom), were four times more likely than nonveterans to have SHI. These findings suggest a need for increased emphasis on improving military hearing conservation programs (HCPs) and on hearing loss surveillance in military and veterans' health systems.

  18. Soft Robotic Haptic Interface with Variable Stiffness for Rehabilitation of Neurologically Impaired Hand Function

    2017-12-01

    Full Text Available The human hand comprises complex sensorimotor functions that can be impaired by neurological diseases and traumatic injuries. Effective rehabilitation can bring the impaired hand back to a functional state because of the plasticity of the central nervous system to relearn and remodel the lost synapses in the brain. Current rehabilitation therapies focus on strengthening motor skills, such as grasping, employ multiple objects of varying stiffness so that affected persons can experience a wide range of strength training. These devices have limited range of stiffness due to the rigid mechanisms employed in their variable stiffness actuators. This paper presents a novel soft robotic haptic device for neuromuscular rehabilitation of the hand, which is designed to offer adjustable stiffness and can be utilized in both clinical and home settings. The device eliminates the need for multiple objects by employing a pneumatic soft structure made with highly compliant materials that act as the actuator of the haptic interface. It is made with interchangeable sleeves that can be customized to include materials of varying stiffness to increase the upper limit of the stiffness range. The device is fabricated using existing 3D printing technologies, and polymer molding and casting techniques, thus keeping the cost low and throughput high. The haptic interface is linked to either an open-loop system that allows for an increased pressure during usage or closed-loop system that provides pressure regulation in accordance to the stiffness the user specifies. Preliminary evaluation is performed to characterize the effective controllable region of variance in stiffness. It was found that the region of controllable stiffness was between points 3 and 7, where the stiffness appeared to plateau with each increase in pressure. The two control systems are tested to derive relationships between internal pressure, grasping force exertion on the surface, and displacement using

    Poorer hearing in the presence of background noise is a significant problem for the hearing impaired. Ototoxic drugs, ageing, and noise exposure can damage the sensory hair cells of the inner ear that are essential for normal hearing sensitivity. The relationship between outer hair cell (OHC) loss and progressively poorer hearing sensitivity in quiet or in competing background noise is supported by a number of human and animal studies. In contrast, the effect of moderate inner hair cell (IHC) loss or dysfunction shows almost no impact on behavioral measures of hearing sensitivity in quiet, when OHCs remain intact, but the relationship between selective IHC loss and hearing in noise remains relatively unknown. Here, a moderately high dose of carboplatin (75 mg/kg) that produced IHC loss in chinchillas ranging from 40 to 80 % had little effect on thresholds in quiet. However, when tested in the presence of competing broadband (BBN) or narrowband noise (NBN), thresholds increased significantly. IHC loss >60 % increased signal-to-noise ratios (SNRs) for tones (500-11,300 Hz) in competing BBN by 5-10 dB and broadened the masking function under NBN. These data suggest that IHC loss or dysfunction may play a significant role in listening in noise independent of OHC integrity and that these deficits may be present even when thresholds in quiet are within normal limits.

    Although cognitive impairments are common following stroke, there is considerable uncertainty about the types of interventions that can reduce activity restrictions and improve quality of life. Indeed, a recent project to identify priorities for research into life after stroke determined that the top priority for patients, carers and health professionals was how to improve cognitive impairments. To provide an overview of the evidence for the effectiveness of cognitive rehabilitation for patients with stroke and to determine the main gaps in the current evidence base. Evidence was synthesised for the six Cochrane reviews relating to rehabilitation for post-stroke cognitive impairment and any subsequently published randomized controlled trials to February 2012. Data arising from 44 trials involving over 1500 patients was identified. Though there was support for the effectiveness of cognitive rehabilitation for some cognitive impairments, significant gaps were found in the current evidence base. All of the Cochrane reviews identified major limitations within the evidence they identified. There is currently insufficient research evidence, or evidence of insufficient quality, to support clear recommendations for clinical practice. Recommendations are made as to the research required to strengthen the evidence base, and so facilitate the delivery of effective interventions to individuals with cognitive impairment after stroke. © The Author(s) 2014.

    Full Text Available OBJECTIVE: Sufficient self-esteem is extremely important for psychosocial functioning. It is hypothesized that hearing-impaired (HI children have lower levels of self-esteem, because, among other things, they frequently experience lower language and communication skills. Therefore, the aim of this study was to compare HI children's self-esteem across different domains with those of normal hearing (NH children and to investigate the influence of communication, type of education, and audiological characteristics. METHODS: This large (N = 252 retrospective, multicenter study consisted of two age- and gender-matched groups: 123 HI children and 129 NH controls (mean age  = 11.8 years. Self-reports were used to measure self-esteem across four domains: perceived social acceptance by peers, perceived parental attention, perceived physical appearance, and global self-esteem. RESULTS: HI children experienced lower levels of self-esteem regarding peers and parents than NH controls. Particularly HI children who attended special education for the deaf were at risk, even after correcting for their language development and intelligence. Yet, levels of global self-esteem and self-esteem involving physical appearance in HI children equalled those of NH controls. Furthermore, younger age at implantation and longer duration of having cochlear implants (CIs were related to higher levels of self-esteem. CONCLUSION: HI children experience lower levels of self-esteem in the social domains. Yet, due to the heterogeneity of the HI population, there is high variability in levels of self-esteem. DISCUSSION: Clinicians must always be aware of the risk and protective factors related to self-esteem in order to help individual patients reach their full potential.

    Full Text Available INTRODUCTION: Hearing loss may impair the development of a child. The rehabilitation process for individuals with hearing loss depends on effective interventions.OBJECTIVE: To describe the linguistic profile and the hearing skills of children using hearing aids, to characterize the rehabilitation process and to analyze its association with the children's degree of hearing loss.METHODS: Cross-sectional study with a non-probabilistic sample of 110 children using hearing aids (6-10 years of age for mild to profound hearing loss. Tests of language, speech perception, phonemic discrimination, and school performance were performed. The associations were verified by the following tests: chi-squared for linear trend and Kruskal-Wallis.RESULTS: About 65% of the children had altered vocabulary, whereas 89% and 94% had altered phonology and inferior school performance, respectively. The degree of hearing loss was associated with differences in the median age of diagnosis; the age at which the hearing aids were adapted and at which speech therapy was started; and the performance on auditory tests and the type of communication used.CONCLUSION: The diagnosis of hearing loss and the clinical interventions occurred late, contributing to impairments in auditory and language development.

  5. Speech perception in older hearing impaired listeners: benefits of perceptual training.

    David L Woods

    Full Text Available Hearing aids (HAs only partially restore the ability of older hearing impaired (OHI listeners to understand speech in noise, due in large part to persistent deficits in consonant identification. Here, we investigated whether adaptive perceptual training would improve consonant-identification in noise in sixteen aided OHI listeners who underwent 40 hours of computer-based training in their homes. Listeners identified 20 onset and 20 coda consonants in 9,600 consonant-vowel-consonant (CVC syllables containing different vowels (/ɑ/, /i/, or /u/ and spoken by four different talkers. Consonants were presented at three consonant-specific signal-to-noise ratios (SNRs spanning a 12 dB range. Noise levels were adjusted over training sessions based on d' measures. Listeners were tested before and after training to measure (1 changes in consonant-identification thresholds using syllables spoken by familiar and unfamiliar talkers, and (2 sentence reception thresholds (SeRTs using two different sentence tests. Consonant-identification thresholds improved gradually during training. Laboratory tests of d' thresholds showed an average improvement of 9.1 dB, with 94% of listeners showing statistically significant training benefit. Training normalized consonant confusions and improved the thresholds of some consonants into the normal range. Benefits were equivalent for onset and coda consonants, syllables containing different vowels, and syllables presented at different SNRs. Greater training benefits were found for hard-to-identify consonants and for consonants spoken by familiar than unfamiliar talkers. SeRTs, tested with simple sentences, showed less elevation than consonant-identification thresholds prior to training and failed to show significant training benefit, although SeRT improvements did correlate with improvements in consonant thresholds. We argue that the lack of SeRT improvement reflects the dominant role of top-down semantic processing in

    Research has clearly demonstrated a link between the attitudes of regular education teachers and the success of inclusion of learners with special educational needs. Therefore, the present study aimed to investigate the attitudes of a group of junior primary school teachers from the Gauteng area towards the inclusion of hearing-impaired children into regular classes. A survey research design was employed which utilized a questionnaire as the research tool. Analysis of results indicated that the teachers surveyed were relatively positive in their attitudes towards inclusion. Greater exposure to disability in terms of training and experience was related to more positive attitudes. Similarly, more positive attitudes were related to greater perceived competence in teaching hearing-impaired pupils. All of the teachers surveyed felt that speech-language pathologists and audiologists (SLPs & As) should be involved in facilitating inclusion of hearing-impaired children. Many of the respondents expressed concern regarding their lack of training, knowledge and skills. The findings from the research project highlight the need for an adequate training and support system for teachers prior to the implementation of an inclusive educational policy, and the potential role of SLPs & As in this regard.

    Internet interventions for hearing aid (HA) users have been shown to be effective in helping persons with hearing problems. As earlier research refers to objective data on these effects, little is known about how participants experience the Internet interventions subjectively. The aim of the present study was to explore participants' experiences of an Internet-based aural rehabilitation (IAR) program for HA-users, and to explore the possible subjective benefits of such a program. A qualitative exploratory design was implemented involving semi-structured telephone interviews. The interviews were transcribed and analysed using content analysis. Interviews were conducted with 20 participants (9 men and 11 women) who had completed an IAR program for HA-users. The participants were 57-81 years old and had used HAs for 2-25 years. The results are organised in three main categories: general experiences associated with participating in the program, knowledge obtained from the program and perceived impact of taking part in the program. The overall results indicate positive experiences of the IAR program, and an overreaching theme of increased self-esteem was identified. The findings provide some valuable information for developers of future IAR programs.

    Parents of children with hearing impairment are at increased risk of mental health morbidities. We examined the predictive factors associated with caregiver's strain and psychological morbidities in parents and family caregivers of children with hearing impairment. In total, n = 201 parents and family caregivers of children with and without hearing impairment aged 3 to 16 years were recruited. Caregiver's strain and psychological morbidities were measured using the Zarit Burden scale and the World Health Organization's Self-Reporting Questionnaire (SRQ-20). Presence of behavioural problems in children was measured using the Strengths and Difficulties Questionnaire. After adjustment, low educational attainment and domestic violence were found to be associated with caregiving strain, whereas dissatisfaction with social support from family, behavioural problems in children, and domestic violence strongly predicted psychological morbidities. Addressing the mental healthcare needs of parents may help in downsizing the impact of psychological morbidities on the well-being of children with hearing impairment.

    Hearing-impaired (HI) listeners often show less masking release (MR) than normal-hearing listeners when temporal fluctuations are imposed on a steady-state masker, even when accounting for overall audibility differences. This difference may be related to a loss of cochlear compression in HI listeners. Behavioral estimates of compression, using temporal masking curves (TMCs), were compared with MR for band-limited (500–4000 Hz) speech and pure tones in HI listeners and age-matched, noise-masked normal-hearing (NMNH) listeners. Compression and pure-tone MR estimates were made at 500, 1500, and 4000 Hz. The amount of MR was defined as the difference in performance between steady-state and 10-Hz square-wave-gated speech-shaped noise. In addition, temporal resolution was estimated from the slope of the off-frequency TMC. No significant relationship was found between estimated cochlear compression and MR for either speech or pure tones. NMNH listeners had significantly steeper off-frequency temporal masking recovery slopes than did HI listeners, and a small but significant correlation was observed between poorer temporal resolution and reduced MR for speech. The results suggest either that the effects of hearing impairment on MR are not determined primarily by changes in peripheral compression, or that the TMC does not provide a sufficiently reliable measure of cochlear compression.

    Full Text Available This study focuses on the development of a profiling system to specify the needs of hearing-aid candidates. As a basis for the profile of compensation needs, we used a slightly modified version of the Amsterdam Inventory of Disability and Handicap, combined with the well-known Client-Oriented Scale of Improvement (COSI. The first questionnaire results in scores for six audiological dimensions: detection, speech in quiet, speech in noise, localization, focus or discrimination, and noise tolerance. The goal of this study was to determine whether the six dimensions derived from the disability questionnaire are appropriate to also categorize individual COSI targets. The results show a good agreement between eight audiologists in the categorization of COSI goals along the six dimensions. The results per dimension show that the dimension focus or discrimination can be regarded as superfluous. Possible additional dimensions were tinnitus and listening effort. The results indicate that it is possible to translate individual user needs (administered using COSI into more general dimensions derived from a disability questionnaire. This allows to summarize the compensation needs for individual patients in a profile of general dimensions, based on the degree of disability and the individual user needs. This profile can be used as a starting point in hearing aid selection. This approach also offers a well-structured method for the evaluation of the postfitting results.

    A long time ago our society accepted the notion of treating people with disabilities not as unviable and disabled but as differently-abled, recognizing their skills beyond their disabilities. The next step has to be taken by our scientific community, that is, to normalize lives of the people with disabilities and make it so as if they are no different to us. The primary step in this direction would be to normalize communication between people. People with an impaired speech or impaired vision or impaired hearing face difficulties while having a casual conversation with others. Any form of communication feels so strenuous that the impaired end up communicating just the important information and avoid a casual conversation. To normalize conversation between the impaired we need a simple and compact device which facilitates the conversation by providing the information in the desired form.

    Similar to visual hallucinations in visually impaired patients, auditory hallucinations are often suggested to occur in adults with hearing impairment. However, research on this association is limited. This observational, cross-sectional study tested whether auditory hallucinations are associated with hearing impairment, by assessing their prevalence in an adult population with various degrees of objectified hearing impairment. Hallucination presence was determined in 1007 subjects aged 18-92, who were referred for audiometric testing to the Department of ENT-Audiology, University Medical Center Utrecht, the Netherlands. The presence and severity of hearing impairment were calculated using mean air conduction thresholds from the most recent pure tone audiometry. Out of 829 participants with hearing impairment, 16.2% (n = 134) had experienced auditory hallucinations in the past 4 weeks; significantly more than the non-impaired group [5.8%; n = 10/173; p impairment, with rates up to 24% in the most profoundly impaired group (p impairment in the best ear. Auditory hallucinations mostly consisted of voices (51%), music (36%), and doorbells or telephones (24%). Our findings reveal that auditory hallucinations are common among patients with hearing impairment, and increase with impairment severity. Although more research on potential confounding factors is necessary, clinicians should be aware of this phenomenon, by inquiring after hallucinations in hearing-impaired patients and, conversely, assessing hearing impairment in patients with auditory hallucinations, since it may be a treatable factor.

    Full Text Available Hearing-impaired people do not hear indoor and outdoor environment sounds, which are important for them both at home and outside. By means of a wearable device that we have developed, a hearing-impaired person will be informed of important sounds through vibrations, thereby understanding what kind of sound it is. Our system, which operates in real time, can achieve a success rate of 98% when estimating a door bell ringing sound, 99% success identifying an alarm sound, 99% success identifying a phone ringing, 91% success identifying honking, 93% success identifying brake sounds, 96% success identifying dog sounds, 97% success identifying human voice, and 96% success identifying other sounds using the audio fingerprint method. Audio fingerprint is a brief summary of an audio file, perceptively summarizing a piece of audio content. In this study, our wearable device is tested 100 times a day for 100 days on five deaf persons and 50 persons with normal hearing whose ears were covered by earphones that provided wind sounds. This study aims to improve the quality of life of deaf persons, and provide them a more prosperous life. In the questionnaire performed, deaf people rate the clarity of the system at 90%, usefulness at 97%, and the likelihood of using this device again at 100%.

    In this paper, a contribution is given to provide a tool to the recognition of sinusoidal signals with a particular reference to the field of pediatric hearing rehabilitation. To this purpose, a synthesis technique previously developed by the authors' is used to design a Cellular Neural Network for an Associative Memory able to compare submitted discrete-time sinusoidal signals with memorized ones. A robustness analysis of the synthesized associative memory is also developed both for noisy inputs and for parameter variations. Simulation results are then reported to illustrate the performances of the designed network.

    Severe to profound hearing impairment (HI) is estimated to affect around 1/2000 young children. Advances in genetics have made it possible to identify several genes related to HI. This information can cast light upon prognostic factors regarding the outcome in cochlear implantation, and provide information both for scientific and genetic counselling purposes. From 1992 to 2005, 273 children from 254 families (probands) were offered cochlear implants in Norway. An evaluation of the causes of HI, especially regarding the genes GJB2, GJB6, SLC26A4, KCNQ1, KCNE1, and the mutation A1555G in mitochondrial DNA was performed in 85% of the families. The number of probands with unknown cause of HI was thus reduced from 120 to 68 (43% reduction). Ninety-eight (46%) of the probands had an identified genetic etiology of their HI. A relatively high prevalence of Jervell and Lange-Nielsen syndrome was found. The main causes of severe and profound HI were similar to those found in other European countries. GJB2 mutations are a common cause of prelingual HI in Norwegian cochlear implanted children.

    Hearing impairment is the most prevalent sensorial deficit in the general population. Congenital deafness occurs in about 1 in 1000 live births, of which approximately 50% has hereditary cause in development countries. Non-syndromic deafness can be caused by mutations in both nuclear and mitochondrial genes. Mutations in mtDNA have been associated with aminoglycoside-induced and non-syndromic deafness in many families worldwide. However, the nuclear background influences the phenotypic expression of these pathogenic mutations. Indeed, it has been proposed that nuclear modifier genes modulate the phenotypic manifestation of the mitochondrial A1555G mutation in the MTRNR1 gene. The both putative nuclear modifiers genes TRMU and MTO1 encoding a highly conserved mitochondrial related to tRNA modification. It has been hypothesizes that human TRMU and also MTO1 nuclear genes may modulate the phenotypic manifestation of deafness-associated mitochondrial mutations. The aim of this work was to elucidate the contribution of mitochondrial mutations, nuclear modifier genes mutations and aminoglycoside exposure in the deafness phenotype. Our findings suggest that the genetic background of individuals may play an important role in the pathogenesis of deafness-associated with mitochondrial mutation and aminoglycoside-induced.

    To analyze educational placement settings of Israeli children with cochlear implants (CIs) and evaluate the prognostic influence of the following demographic variables on mainstreaming: age at implantation, experience with CI, socioeconomic status, ethnicity, and parents' educational level. Retrospective review. Tertiary referral center. The study population comprised 245 children with severe-to-profound hearing impairment and at least 1 year of experience with a unilateral CI. Mean age at implantation was 4.5 ± 3.9 years, and mean duration of CI use was 5.4 ± 2.8 years. Follow-up review and statistical analysis of available data on educational placement after cochlear implantation. Placement in mainstream education. Regular schools were attended by 89 children (36.3%) and special education schools by 156 (63.7%). Variables found to be significantly associated with mainstream educational placement were younger age at implantation, higher level of parental education, higher socioeconomic status, and ethnicity. Multivariate analysis using a logistic regression model revealed that the factor with the highest positive correlation with mainstreaming was parental education level. Our results show that parental education, a variable that the health system cannot control, significantly influences postimplantation results in term of educational placement and can thus limit the chances of implanted children to achieve mainstream placement even when identified and implanted at an early age.

    Full Text Available Previous studies have demonstrated that successful listening with advanced signal processing in digital hearing aids is associated with individual cognitive capacity, particularly working memory capacity (WMC. This study aimed to examine the relationship between cognitive abilities (cognitive processing speed and WMC and individual listeners’ responses to digital signal processing settings in adverse listening conditions. A total of 194 native Swedish speakers (83 women and 111 men, aged 33–80 years (mean = 60.75 years, SD = 8.89, with bilateral, symmetrical mild to moderate sensorineural hearing loss who had completed a lexical decision speed test (measuring cognitive processing speed and semantic word-pair span test (SWPST, capturing WMC participated in this study. The Hagerman test (capturing speech recognition in noise was conducted using an experimental hearing aid with three digital signal processing settings: (1 linear amplification without noise reduction (NoP, (2 linear amplification with noise reduction (NR, and (3 non-linear amplification without NR (“fast-acting compression”. The results showed that cognitive processing speed was a better predictor of speech intelligibility in noise, regardless of the types of signal processing algorithms used. That is, there was a stronger association between cognitive processing speed and NR outcomes and fast-acting compression outcomes (in steady state noise. We observed a weaker relationship between working memory and NR, but WMC did not relate to fast-acting compression. WMC was a relatively weaker predictor of speech intelligibility in noise. These findings might have been different if the participants had been provided with training and or allowed to acclimatize to binary masking noise reduction or fast-acting compression.

    Full Text Available Objective: To describe the audiological findings (type, audiometric configuration, degree of hearing loss and its association with gender and age in subjects aged over 60 years, treated at outpatient clinic of specialties of Manaus. Methods: A cross-sectional epidemiological descriptive study conducted with the universe of elderly who underwent audiometry from January to December 2010, with a total of 574 subjects. To classify the type, degree and configuration of hearing loss, we used the criteria adopted by Santos & Russo, Davis & Silverman and Silman & Silverman, respectively. Statistical analysis was performed using measures of central tendency, dispersion and frequency distributions. To check for statistically significant differences, we used the chi-square test, with a significance level of 5% (p ≤ 0.05. Results: The prevalence of 94.4% (n = 542 of hearing loss, sensorineural predominantly (85.5%, n = 491 and mild (60%, n = 188 in females and degree moderate or greater in males (50%, n = 130, downward sloping (54.2%, n = 311 in both sexes. The percentage of normality was low, with 261 (3.4% for men and 313 (7.3% for women. Conclusion: The prevalence of hearing loss increased with age, being equal to 100% in individuals 80 years or older, and men have the worst hearing thresholds. There is need for greater awareness about hearing loss in the elderly, needing additional population-based and multicentric studies in order to support public policies.

    An estimated 36 million US citizens have impaired hearing, but nearly half of them have never had a hearing test. As noted by a recent National Institutes of Health/National Institute on Deafness and Other Communication Disorders (NIH/NIDCD) Working Group, "In the United States (in contrast to many other nations) there are no readily accessible low cost hearing screening programs…" (Donahue et al, 2010, p. 2). Since 2004, telephone administered screening tests utilizing three-digit sequences presented in noise have been developed, validated, and implemented in seven countries. Each of these tests has been based on a test protocol conceived by Smits and colleagues in The Netherlands. Investigators from Communication Disorders Technology, Inc., Indiana University, and VU University Medical Center of Amsterdam agreed to collaborate in the development and validation of a screening test for hearing impairment suitable for delivery over the telephone, for use in the United States. This test, utilizing spoken three-digit sequences (triplets), was to be based on the design of Smits and his colleagues. A version of the digits-in-noise test was developed utilizing digit triplets spoken in Middle American dialect. The stimuli were individually adjusted to speech-to-noise ratio (SNR) values yielding 50% correct identification, on the basis of data collected from a group of 10 young adult listeners with normal hearing. A final set of 64 homogeneous stimuli were selected from an original 160 recorded triplets. Each test consisted of a series of 40 triplets drawn at random, presented in a noise background. The SNR threshold for 50% correct identification of the triplets was determined by a one-down, one-up adaptive procedure. The test was implemented by telephone, and administered to listeners with varying levels of hearing impairment. The listeners were then evaluated with pure-tone tests and other audiometric measures as clinically appropriate. Ninety participants included 72

    The Tennessee Mouse Genome Consortium (TMGC) employed an N-ethyl-N-nitrosourea (ENU)-mutagenesis scheme to identify mouse recessive mutants with hearing phenotypes. We employed auditory brainstem responses (ABR) to click and 8, 16, and 32 kHz stimuli and screened 285 pedigrees (1819 mice of 8-11 weeks old in various mixed genetic backgrounds) each bred to carry a homozygous ENU-induced mutation. To define mutant pedigrees, we measured P12 mice per pedigree in P2 generations and used a criterion where the mean ABR threshold per pedigree was two standard deviations above the mean of all offspring from the same parental strain. We thus identified 17 mutant pedigrees (6%), all exhibiting hearing loss at high frequencies (P16 kHz) with an average threshold elevation of 30-35 dB SPL. Interestingly, four mutants showed sex-biased hearing loss and six mutants displayed wide range frequency hearing loss. Temporal bone histology revealed that six of the first nine mutants displayed cochlear morphological defects: degeneration of spiral ganglia, spiral ligament fibrocytes or inner hair cells (but not outer hair cells) mostly in basal turns. In contrast to other ENU-mutagenesis auditory screens, our screen identified high-frequency, mild and sex-biased hearing defects. Further characterization of these 17 mouse models will advance our understanding of presbycusis and noise-induced hearing loss in humans.

    Cognitive screening tests frequently rely on items being correctly heard or seen. We aimed to identify, describe, and evaluate the adaptation, validity, and availability of cognitive screening and assessment tools for dementia which have been developed or adapted for adults with acquired hearing and/or vision impairment. Electronic databases were searched using subject terms "hearing disorders" OR "vision disorders" AND "cognitive assessment," supplemented by exploring reference lists of included papers and via consultation with health professionals to identify additional literature. 1,551 papers were identified, of which 13 met inclusion criteria. Four papers related to tests adapted for hearing impairment; 11 papers related to tests adapted for vision impairment. Frequently adapted tests were the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MOCA). Adaptations for hearing impairment involved deleting or creating written versions for hearing-dependent items. Adaptations for vision impairment involved deleting vision-dependent items or spoken/tactile versions of visual tasks. No study reported validity of the test in relation to detection of dementia in people with hearing/vision impairment. Item deletion had a negative impact on the psychometric properties of the test. While attempts have been made to adapt cognitive tests for people with acquired hearing and/or vision impairment, the primary limitation of these adaptations is that their validity in accurately detecting dementia among those with acquired hearing or vision impairment is yet to be established. It is likely that the sensitivity and specificity of the adapted versions are poorer than the original, especially if the adaptation involved item deletion. One solution would involve item substitution in an alternative sensory modality followed by re-validation of the adapted test.

Although the association between cardiovascular diseases and cognitive impairments (CIs is well known, the prevalence particularly of mild CI in CR and the characteristics of affected patients have been insufficiently investigated so far. Methods: In this prospective observational study, 496 patients (54.5 ± 6.2 years, 79.8% men with coronary artery disease following an acute coronary event (ACE were analyzed. Patients were enrolled within 14 days of discharge from the hospital in a 3-week inpatient CR program. Patients were tested for CI using the Montreal Cognitive Assessment (MoCA upon admission to and discharge from CR. Additionally, sociodemographic, clinical, and physiological variables were documented. The data were analyzed descriptively and in a multivariate stepwise backward elimination regression model with respect to CI. Results: At admission to CR, the CI (MoCA score < 26 was determined in 182 patients (36.7%. Significant differences between CI and no CI groups were identified, and CI group was associated with high prevalence of smoking (65.9 vs 56.7%, P = 0.046, heavy (physically demanding workloads (26.4 vs 17.8%, P < 0.001, sick leave longer than 1 month prior to CR (28.6 vs 18.5%, P = 0.026, reduced exercise capacity (102.5 vs 118.8 W, P = 0.006, and a shorter 6-min walking distance

    Full Text Available This study aimed to evaluate the association between rheumatoid arthritis (RA and hearing impairment in the Korean adult population. Audiometric and laboratory test data from the 2010-2012 Korean National Health and Nutrition Examination Survey (KNHANES were used for analysis. The relationship between RA and hearing impairment was analyzed, adjusting for various known risk factors associated with hearing impairment. RA was defined in the questionnaire as "RA diagnosed by a physician (yes/no through a standardized interview." We defined hearing impairment according to 2 categories of frequency (low/mid and high as follows (average values in kHz: low/mid frequency, 0.5, 1.0, and 2.0, and high frequency, 3.0, 4.0, and 6.0. Of the subjects, 15,158 (weighted n = 32,035,996 completed the audiometric tests. The overall weighted prevalence of RA was 1.5%. The prevalence of hearing impairment was higher in the subjects with RA than in those without RA, in both, the low/mid- and high-frequency categories (21.1% vs 7.5%, p < 0.001 and 43.3% vs. 26.2%, p < 0.001, respectively. In the multivariable logistic analysis, RA (odds ratios [OR] 1.47, 95% confidence interval [CI] 1.05-2.06, p = 0.025 was an independent risk factor of low/mid-frequency hearing impairment along with age (OR 1.12, 95% CI 1.12-1.13, p < 0.001, current smoking (OR 1.27, 95% CI 1.03-1.56, p = 0.026, and college graduation (OR 0.53, 95% CI 0.39-0.72, p < 0.001. In the multivariable analysis of high-frequency hearing impairment, RA did not show any association with hearing impairment. This study suggests that RA is associated with low/mid-frequency hearing impairment after adjustment for various known risk factors. Further study is needed to verify the hearing impairment in RA.

  13. Application of massively parallel sequencing to genetic diagnosis in multiplex families with idiopathic sensorineural hearing impairment.

    Directory of Open Access Journals (Sweden)

    Chen-Chi Wu

    Full Text Available Despite the clinical utility of genetic diagnosis to address idiopathic sensorineural hearing impairment (SNHI, the current strategy for screening mutations via Sanger sequencing suffers from the limitation that only a limited number of DNA fragments associated with common deafness mutations can be genotyped. Consequently, a definitive genetic diagnosis cannot be achieved in many families with discernible family history. To investigate the diagnostic utility of massively parallel sequencing (MPS, we applied the MPS technique to 12 multiplex families with idiopathic SNHI in which common deafness mutations had previously been ruled out. NimbleGen sequence capture array was designed to target all protein coding sequences (CDSs and 100 bp of the flanking sequence of 80 common deafness genes. We performed MPS on the Illumina HiSeq2000, and applied BWA, SAMtools, Picard, GATK, Variant Tools, ANNOVAR, and IGV for bioinformatics analyses. Initial data filtering with allele frequencies (0.95 prioritized 5 indels (insertions/deletions and 36 missense variants in the 12 multiplex families. After further validation by Sanger sequencing, segregation pattern, and evolutionary conservation of amino acid residues, we identified 4 variants in 4 different genes, which might lead to SNHI in 4 families compatible with autosomal dominant inheritance. These included GJB2 p.R75Q, MYO7A p.T381M, KCNQ4 p.S680F, and MYH9 p.E1256K. Among them, KCNQ4 p.S680F and MYH9 p.E1256K were novel. In conclusion, MPS allows genetic diagnosis in multiplex families with idiopathic SNHI by detecting mutations in relatively uncommon deafness genes.

    When two white noises differing only in phase in a particular frequency range are presented simultaneously each to one of our ears, a pitch sensation may be perceived inside the head. This phenomenon, called ’binaural pitch’ or ’dichotic pitch’, can be produced by frequency-dependent interaural...... phasedifference patterns. The evaluation of these interaural phase differences depends on the functionality of the binaural auditory system and the spectro-temporal information at its input. A melody recognition task was performed in the present study using pure-tone stimuli and six different types of noises...... that can generate a binaural pitch sensation.

    2014-03-01

    Consonant recognition was assessed in normal-hearing (NH) and hearing-impaired (HI) listeners in quiet as a function of speech level using a nonsense logatome test. Average recognition scores were analyzed and compared to recognition scores of a speech recognition model. In contrast to commonly used spectral speech recognition models operating on long-term spectra, a "microscopic" model operating in the time domain was used. Variations of the model (accounting for hearing impairment) and different model parameters (reflecting cochlear compression) were tested. Using these model variations this study examined whether speech recognition performance in quiet is affected by changes in cochlear compression, namely, a linearization, which is often observed in HI listeners. Consonant recognition scores for HI listeners were poorer than for NH listeners. The model accurately predicted the speech reception thresholds of the NH and most HI listeners. A partial linearization of the cochlear compression in the auditory model, while keeping audibility constant, produced higher recognition scores and improved the prediction accuracy. However, including listener-specific information about the exact form of the cochlear compression did not improve the prediction further.

    The present study investigates how auditory stimulation from cochlear implants (CI) is associated with the development of Theory of Mind (ToM) in severely and profoundly hearing impaired children with hearing parents. Previous research has shown that deaf children of hearing parents have a delayed ToM development. This is, however, not always the case with deaf children of deaf parents, who presumably are immersed in a more vivid signing environment. Sixteen children with CI (4.25 to 9.5 years of age) were tested on measures of cognitive and emotional ToM, language and cognition. Eight of the children received their first implant relatively early (before 27 months) and half of them late (after 27 months). The two groups did not differ in age, gender, language or cognition at entry of the study. ToM tests included the unexpected location task and a newly developed Swedish social-emotional ToM test. The tests aimed to test both cognitive and emotional ToM. A comparison group of typically developing hearing age matched children was also added (n=18). Compared to the comparison group, the early CI-group did not differ in emotional ToM. The late CI-group differed significantly from the comparison group on both the cognitive and emotional ToM tests. The results revealed that children with early cochlear implants solved ToM problems to a significantly higher degree than children with late implants, although the groups did not differ on language or cognitive measures at baseline. The outcome suggests that early cochlear implantation for deaf children in hearing families, in conjunction with early social and communicative stimulation in a language that is native to the parents, can provide a foundation for a more normalized ToM development.

    Full Text Available AIM:To develop a short, enhanced functional ability Quality of Vision (faVIQ instrument based on previous questionnaires employing comprehensive modern statistical techniques to ensure the use of an appropriate response scale, items and scoring of the visual related difficulties experienced by patients with visual impairment.METHODS:Items in current quality-of-life questionnaires for the visually impaired were refined by a multi-professional group and visually impaired focus groups. The resulting 76 items were completed by 293 visually impaired patients with stable vision on two occasions separated by a month. The faVIQ scores of 75 patients with no ocular pathology were compared to 75 age and gender matched patients with visual impairment.RESULTS:Rasch analysis reduced the faVIQ items to 27. Correlation to standard visual metrics was moderate (r=0.32-0.46 and to the NEI-VFQ was 0.48. The faVIQ was able to clearly discriminate between age and gender matched populations with no ocular pathology and visual impairment with an index of 0.983 and 95% sensitivity and 95% specificity using a cut off of 29.CONCLUSION:The faVIQ allows sensitive assessment of quality-of-life in the visually impaired and should support studies which evaluate the effectiveness of low vision rehabilitation services.

    Doyle, J; Wong, L L

    1996-12-01

    This paper addresses the observation that some Cantonese-speaking adults do not perceive a hearing problem even when hearing screening identifies hearing loss. A sample of 49 Cantonese speakers was surveyed about their self-perceptions of hearing prior to a 25 dB HTL pure-tone screening test. All 49 persons failed the screening test, yet 34 (69.4%) reported that they had no problems hearing during conversations. Persons who admitted hearing difficulties tended to have mean hearing levels in excess of 45 dB HTL. A number of hypotheses concerning cultural and linguistic influences are proposed as explanations for the apparent lack of significance of auditory sensitivity loss for some Cantonese speakers. Ways in which these hypotheses might be tested are suggested.

    The purpose of this study was to establish test-retest reliability of centre of pressure (COP) measurements obtained by an AccuGait portable forceplate (ACG), mean COG sway velocity measured by a Basic Balance Master (BBM) and clinical balance tests in children with and without balance difficulties. 49 typically developing children and 23 hearing impaired children, with a higher risk for stability problems, between 6 and 12 years of age participated. Each child performed the modified Clinical Test of Sensory Interaction on Balance (mCTSIB), Unilateral Stance (US) and Tandem Stance on ACG, mCTSIB and US on BBM and clinical balance tests: one-leg standing, balance beam walking and one-leg hopping. All subjects completed 2 test sessions on 2 different days in the same week assessed by the same examiner. Among COP measurements obtained by the ACG, mean sway velocity was the most reliable parameter with all ICCs higher than 0.72. The standard deviation (SD) of sway velocity, sway area, SD of anterior-posterior and SD of medio-lateral COP data showed moderate to excellent reliability with ICCs between 0.55 and 0.96 but some caution must be taken into account in some conditions. BBM is less reliable but clinical balance tests are as reliable as ACG. Hearing impaired children exhibited better relative reliability (ICC) and comparable absolute reliability (SEM) for most balance parameters compared to typically developing children. Reliable information regarding postural stability of typically developing children and hearing impaired children may be obtained utilizing COP measurements generated by an AccuGait system and clinical balance tests.

    Previously we confirmed linkage of autosomal dominantly inherited low-frequency sensorineural hearing impairment (LFSNHI) in a German family to the genetic locus DFNA6/DFNA14 on chromosome 4p16.3 close to the markers D4S432 and D4S431. Analysis of data from the Human Genome Project, showed that WFS1 is located in this region. Mutations in WFS1 are known to be responsible for Wolfram syndrome (DIDMOAD, MIM no. 606201), which follows an autosomal recessive trait. Studies in low-frequency hearing loss families showed that mutations in WFS1 were responsible for the phenotype. In all affected family members analysed, we detected a missense mutation in WFS1 (K705N) and therefore confirm the finding that the majority of mutations responsible for LFSNHI are missense mutations which localise to the C-terminal domain of the protein.

    The co-occurrence of hearing impairment and visual dysfunction is devastating. Most deaf-blind etiologies are genetically determined, the commonest being Usher syndrome (USH). While studies of the congenitally deaf population reveal a variable degree of visual problems, there are no effective ophthalmic screening guidelines. We hypothesized that children with congenital sensorineural hearing loss (SNHL) and vestibular impairment were at an increased risk of having USH. A retrospective chart review of 33 cochlear implants recipients for severe to profound SNHL and measured vestibular dysfunction was performed to determine the ocular phenotype. All the cases had undergone ocular examination and electroretinogram (ERG). Patients with an abnormal ERG underwent genetic testing for USH. We found an underlying ocular abnormality in 81.81% (27/33) of cases; of which 75% had refractive errors, and 50% of those patients showed visual improvement with refractive correction. A total of 14 cases (42.42%; 14/33) had generalized rod-cone dysfunction on ERG suggestive of Usher syndrome type 1, confirmed by mutational analysis. This work shows that adding vestibular impairment as a criterion for requesting an eye exam and adding the ERG to detect USH increases the chances of detecting ocular anomalies, when compared with previous literature focusing only on congenital SNHL. © 2016 John Wiley & Sons A/S.

    Full Text Available Background: Visual impairment (VI and hearing impairment (HI are the two most common types of sensory disability encountered clinically. However, VI and HI result in different limitations in daily life. We assessed the level of functioning in patients with VI or HI based on the International Classification of Functioning, Disability, and Health. Methods: This nationwide, cross-sectional study included 312 people with VI and 540 people with HI. Each participant's degree of functioning and disability was evaluated using the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0. The standardized WHODAS 2.0 scores ranged from 0 (least difficulty to 100 (most difficulty. Results: Patients with VI and those with HI had a mean (±standard error 32-item WHODAS 2.0 score of 42.4 ± 2.9 and 27.1 ± 1.6, respectively. The degree of restriction was positively related to the level of VI. Specifically, the patients with VI and a WHODAS 2.0 score of 33.7–35.3 or higher were likely to experience barriers to accessing mobility products, communication products, and education products. Furthermore, patients with a score of 42.9 or higher might experience barriers to accessing ingestion products and living products. Conclusion: WHODAS 2.0 scores are strongly correlated with the severity of VI. Mild VI should be targeted for treatment and referral as early as possible. Compared with the patients with HI, the patients with VI more frequently experience barriers to accessing environmental factors.

  13. Effects of rehabilitative interventions on pain, function and physical impairments in people with hand osteoarthritis: a systematic review

    Science.gov (United States)

    2011-01-01

    Introduction Hand osteoarthritis (OA) is associated with pain, reduced grip strength, loss of range of motion and joint stiffness leading to impaired hand function and difficulty with daily activities. The effectiveness of different rehabilitation interventions on specific treatment goals has not yet been fully explored. The objective of this systematic review is to provide evidence based knowledge on the treatment effects of different rehabilitation interventions for specific treatment goals for hand OA. Methods A computerized literature search of Medline, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), ISI Web of Science, the Physiotherapy Evidence Database (PEDro) and SCOPUS was performed. Studies that had an evidence level of 2b or higher and that compared a rehabilitation intervention with a control group and assessed at least one of the following outcome measures - pain, physical hand function or other measures of hand impairment - were included. The eligibility and methodological quality of trials were systematically assessed by two independent reviewers using the PEDro scale. Treatment effects were calculated using standardized mean difference and 95% confidence intervals. Results Ten studies, of which six were of higher quality (PEDro score >6), were included. The rehabilitation techniques reviewed included three studies on exercise, two studies each on laser and heat, and one study each on splints, massage and acupuncture. One higher quality trial showed a large positive effect of 12-month use of a night splint on hand pain, function, strength and range of motion. Exercise had no effect on hand pain or function although it may be able to improve hand strength. Low level laser therapy may be useful for improving range of motion. No rehabilitation interventions were found to improve stiffness. Conclusions There is emerging high quality evidence to support that rehabilitation interventions can offer significant benefits to individuals

    Full Text Available Identification and modification of the risk factors for cognitive decline throughout the adult life span are priority subjects in a progressively aging society; however, much remains to be learned. The aim of this study was to understand whether changes in cognitive function can be affected by hearing impairment (HI and whether the impact of HI differs depending on the cognitive domain. A total of 1,109 individuals aged 60 – 79 years at baseline who participated in the Longitudinal Study of Aging at the National Institute for Longevity Sciences (NILS-LSA was followed up for a maximum of 13.3 years. Cognitive function was evaluated using four subtests of the Japanese Wechsler Adult Intelligence Scale-Revised Short Forms: namely, Information, Similarities, Picture Completion, and the Digit Symbol Substitution subtests. The HI was defined as a pure-tone average of the better ear greater than 25 dB. A longitudinal analysis was performed of 4,437 observations obtained during a follow-up period of approximately 12 years. We estimated linear changes in subtest scores by HI status, using the time-varying mixed-effects regression model, which included fixed terms for the intercept, HI status at baseline, time (years elapsed since baseline, and an HI × time interaction term adjusted for age at baseline, sex, education, and other possible confounders. There were significant main effects of HI on the scores of the four subtests after adjustment. The HI × time interaction was significant for the scores of the Information (p = 0.001 and Digit Symbol Substitution subtests (p = 0.001. The scores of the HI group declined faster in the Information and Digit Symbol Substitution subtests compared to those of the no-HI group. The model-predicted 12-year slope using a mean baseline age (68.7 years indicated no significant decline in the individuals without HI at baseline for the Information and Similarities subtests, however, this tolerance was lost in the

    Full Text Available CONTEXT AND OBJECTIVE: Oral narrative is a means of language development assessment. However, standardized data for deaf patients are scarce. The aim here was to compare the use of narrative competence between hearing-impaired and normal-hearing children. DESIGN AND SETTING: Analytical cross-sectional study at the Department of Speech-Language and Hearing Sciences, Universidade Federal de São Paulo. METHODS: Twenty-one moderately to profoundly bilaterally hearing-impaired children (cases and 21 normal-hearing children without language abnormalities (controls, matched according to sex, age, schooling level and school type, were studied. A board showing pictures in a temporally logical sequence was presented to each child, to elicit a narrative, and the child's performance relating to narrative structure and cohesion was measured. The frequencies of variables, their associations (Mann-Whitney test and their 95% confidence intervals was analyzed. RESULTS: The deaf subjects showed poorer performance regarding narrative structure, use of connectives, cohesion measurements and general punctuation (P < 0.05. There were no differences in the number of propositions elaborated or in referent specification between the two groups. The deaf children produced a higher proportion of orientation-related propositions (P = 0.001 and lower proportions of propositions relating to complicating actions (P = 0.015 and character reactions (P = 0.005. CONCLUSION: Hearing-impaired children have abnormalities in different aspects of language, involving form, content and use, in relation to their normal-hearing peers. Narrative competence was also associated with the children's ages and the school type.

        Using disability theory as a framework and social science theories of identity to strengthen the arguments, this paper explores empirically how working-age adults confront the medical diagnosis of hearing impairment. For most participants hearing impairment threatens the stability of social...... interaction and the construction of hearing disabled identities is seen as shaped in the interaction with the hearing impaired person‟s surroundings. In order to overcome the potential stigmatisation the „passing‟ as normal becomes predominant. For many the diagnosis provokes radical redefinitions of the self....... The discursively produced categorisation and subjectivity of senescence mean that rehabilitation technologies such as hearing aids identify a particular life-style (disabled) which determines their social significance.

    2017-12-01

    Full Text Available This study investigated eye-movement patterns during emotion perception for children with hearing aids and hearing children. Seventy-eight participants aged from 3 to 7 were asked to watch videos with a facial expression followed by an oral statement, and these two cues were either congruent or incongruent in emotional valence. Results showed that while hearing children paid more attention to the upper part of the face, children with hearing aids paid more attention to the lower part of the face after the oral statement was presented, especially for the neutral facial expression/neutral oral statement condition. These results suggest that children with hearing aids have an altered eye contact pattern with others and a difficulty in matching visual and voice cues in emotion perception. The negative cause and effect of these gaze patterns should be avoided in earlier rehabilitation for hearing-impaired children with assistive devices.

    Full Text Available Introduction: Over 5% of the world's population has disabling hearing loss. The oral health of the disabled may be disused for the reason of the disabling condition, a challenging disease or the limited access to oral health care. Objectives: The objectives of the study were to assess the prevalence of dental caries and periodontal status of institutionalized hearing impaired (HI children in Khordha district of Odisha. Materials and Methods: A descriptive cross-sectional study on the HI children was conducted in Khordha district, Odisha. Type III examination procedure was conducted to assess the oral health status of the children. Statistical analysis was performed by Chi-square test and Student's t-test, and the significance level was fixed at P < 0.05. Results: The final population consisted of 540 HI children out of which 262 (48.5% were male and 278 (51.5% were female, 285 (52.8% children had severe hearing loss and 227 (42.0% had profound hearing loss. Bleeding on probing was found in 72 (13.3% female children as compared to 57 (10.6% male children. While 131 (24.3% female children had calculus, 124 (23.0% male children had the same condition. Total caries prevalence was 19.3%. Statistically highly significant difference was found for mean decayed teeth (DT, missing teeth decayed, missing filled teeth (FT (P < 0.001, while for mean FT there was no statistically significant difference according to age groups. Statistically highly significant difference was found for mean DT, extracted teeth and decayed, extracted, filled teeth (P < 0.001. Conclusion: An improved accessibility to dental services as well as dental health education is necessary to ensure the optimum dental health within the reach of these less fortunate children.

    A novel approach for assisting bidirectional communication between people of normal hearing and hearing-impaired is presented. While the existing hearing-impaired assistive devices such as hearing aids and cochlear implants are vulnerable in extreme noise conditions or post-surgery side effects, the proposed concept is an alternative approach wherein spoken dialogue is achieved by means of employing a robust speech recognition technique which takes into consideration of noisy environmental factors without any attachment into human body. The proposed system is a portable device with an acoustic beamformer for directional noise reduction and capable of performing speech-to-text transcription function, which adopts a keyword spotting method. It is also equipped with an optimized user interface for hearing-impaired people, rendering intuitive and natural device usage with diverse domain contexts. The relevant experimental results confirm that the proposed interface design is feasible for realizing an effective and efficient intelligent agent for hearing-impaired.

    2017-03-01

    This article reviews and critically analyzes the design of studies on the effect of audiological rehabilitation (AR) programs on hearing aid (HA) outcomes, in order to guide future research. The design of this study was a narrative review. Studies were included in the review if they were randomized controlled trials that investigated the effects of AR on HA use and outcome between 2000 and 2016. Seven articles that met the inclusion criteria were included in the review. Most used educational rather than counseling approaches. Although educational AR programs seem to be useful in enhancing the use of communication strategies, there is limited evidence for their effect on HA use and self-perceived hearing handicap. More research is needed in this field. Future studies should (1) investigate the efficacy of AR interventions based on counseling and empathetic listening as opposed to or in addition to educational interventions, (2) use stricter criteria to include only a subpopulation of patients who do not get on well with their HAs, (3) measure the amount of HA use via data-logging and self-report questionnaires, and (4) use a matching comparison intervention for patients in the control group.

    Objective . To describe and quantify hearing impairment among children referred to the audiology clinic in Princess Marina Hospital, a public referral hospital in Botswana. Methods . In a retrospective case series, we reviewed medical records of children aged 10 years and younger whose hearing was assessed between January 2006 and December 2015 at the audiology clinic of Princess Marina Hospital in Gaborone, Botswana. Results . Of 622 children, 50% were male, and median age was 6.7 years (interquartile range = 5.0-8.3). Hearing impairment was diagnosed in 32% of clinic attendees, comprising sensorineural (23%), conductive (25%), and mixed (11%) hearing loss, while 41% of children with diagnosed hearing impairment did not have a classification type. Hearing impairment was mild in 22.9%, moderate in 22.4%, severe in 19.4%, profound in 16.9%, and of undocumented severity in 18.4%. Children younger than 5 years were 2.7 times (95% confidence interval = 1.29-5.49; P = .008) more likely to be diagnosed with sensorineural hearing impairment compared with those older than 5 years. By contrast, children older than 5 years were 9.6 times (95% confidence interval = 2.22-41.0; P = .002) more likely to be diagnosed with conductive hearing loss compared with those under 5 years. Conclusion . Hearing impairment was common among children referred to this audiology clinic in Botswana. Of those with hearing impairment, more than a third had moderate or severe deficits, suggesting that referrals for hearing assessments are not occurring early enough. Hearing awareness programs individually tailored to parents, educators, and health care workers are needed. Neonatal and school hearing screening programs would also be beneficial.

Results from 12 listeners with sensorineural hearing loss showed reduced masker phase effects, when compared with data from normal-hearing listeners, at both 250- and 1000-Hz signal frequencies. The effects of hearing impairment on phase-related masking differences were not well simulated...... are affected by a common underlying mechanism, presumably related to cochlear outer hair cell function. The results also suggest that normal peripheral compression remains strong even at 250 Hz....

    Recent research has revealed an association between hearing impairment and dementia. The objective of this study is to determine the effect of hearing impairment on dementia incidence in a longitudinal study, and whether ear, nose, and throat (ENT) specialist care, care level, institutionalization, or depression mediates or moderates this pathway. The present study used a longitudinal sample of 154,783 persons aged 65 and older from claims data of the largest German health insurer; containing 14,602 incident dementia diagnoses between 2006 and 2010. Dementia and hearing impairment diagnoses were defined according to International Classification of Diseases, Tenth Revision, codes. We used a Kaplan Meier estimator and performed Cox proportional hazard models to explore the effect of hearing impairment on dementia incidence, controlling for ENT specialist care, care level, institutionalization, and depression. Gender, age, and comorbidities were controlled for as potential confounders. Patients with bilateral (HR = 1.43, pimpairment had higher risks of dementia incidence than patients without hearing impairment. We found no significant effect for unilateral hearing impairment and other diseases of the ear. The effect of hearing impairment was only partly mediated through ENT specialist utilization. Significant interaction between hearing impairment and specialist care, care level, and institutionalization, respectively, indicated moderating effects. We discuss possible explanations for these effects. This study underlines the importance of the association between hearing impairment and dementia. Preserving hearing ability may maintain social participation and may reduce the burden associated with dementia. The particular impact of hearing aid use should be the subject of further investigations, as it offers potential intervention on the pathway to dementia. PMID:27391486

Objective This study aims to evaluate the effects of a multidisciplinary rehabilitation program on cognitive ability, quality of life and depression symptoms in patients with Alzheimer’s disease (AD and cognitive impairment without dementia (CIND. Methods Ninety-seven older adults were recruited to the present study. Of these, 70 patients had mild AD and were allocated into experimental (n = 54 or control (n = 16 groups. Two additional active comparison groups were constituted with patients with moderate AD (n = 13 or with CIND (n = 14 who also received the intervention. The multidisciplinary rehabilitation program lasted for 12 weeks and was composed by sessions of memory training, recreational activities, verbal expression and writing, physical therapy and physical training, delivered in two weekly 6-hour sessions. Results As compared to controls, mild AD patients who received the intervention had improvements in cognition (p = 0.021 and quality of life (p = 0.003, along with a reduction in depressive symptoms (p < 0.001. As compared to baseline, CIND patients displayed at the end of the intervention improvements in cognition (p = 0.005 and depressive symptoms (p = 0.011. No such benefits were found among patients with moderate AD.Discussion: This multidisciplinary rehabilitation program was beneficial for patients with mild AD and CIND. However, patients with moderate dementia did not benefit from the intervention.

    Full Text Available Access to ICT is an important issue in contemporary societies, especially in vulnerable groups. From a case study of hearing impaired people living in Zaragoza, we study the assumption of ICT as a resource for socializing as well as the opinions and asses on them. In general, members of this group recognize the value and importance of ICT to information, communication and socialization. There are differences in their access between deaf persons with knowing of sign language or without it. Trends such as the increased use of smartphones replacing computers or valuation of certain risks or dangers associated ICT are identified. The domain in the use of ICT is conditioned by variables such as knowing of sign language, the age and condition of digital native.

    The study aimed (a) to profile audiologists' language during the diagnosis and management planning phase of hearing assessment appointments and (b) to explore associations between audiologists' language and patients' decisions to obtain hearing aids. Sixty-two audiologist-patient dyads participated. Patient participants were aged 55 years or older. Hearing assessment appointments were audiovisually recorded and transcribed for analysis. Audiologists' language was profiled using two measures: general language complexity and use of jargon. A binomial, multivariate logistic regression analysis was conducted to investigate the associations between these language measures and hearing aid uptake. The logistic regression model revealed that the Flesch-Kincaid reading grade level of audiologists' language was significantly associated with hearing aid uptake. Patients were less likely to obtain hearing aids when audiologists' language was at a higher reading grade level. No associations were found between audiologists' use of jargon and hearing aid uptake. Audiologists' use of complex language may present a barrier for patients to understand hearing rehabilitation recommendations. Reduced understanding may limit patient participation in the decision-making process and result in patients being less willing to trial hearing aids. Clear, concise language is recommended to facilitate shared decision making.

    Full Text Available Lifestyle including smoking, noise exposure with MP3 player and drinking alcohol are considered as risk factors for affecting hearing synergistically. However, little is known about the association of cigarette smoking with hearing impairment among subjects who carry a lifestyle without using MP3 player and drinking alcohol. We showed here the influence of smoking on hearing among Bangladeshi subjects who maintain a lifestyle devoid of using MP3 player and drinking alcohol. A total of 184 subjects (smokers: 90; non-smokers: 94 were included considering their duration and frequency of smoking for conducting this study. The mean hearing thresholds of non-smoker subjects at 1, 4, 8 and 12 kHz frequencies were 5.63 ± 2.10, 8.56±5.75, 21.06 ± 11.06, 40.79 ± 20.36 decibel (dB, respectively and that of the smokers were 7 ± 3.8, 13.27 ± 8.4, 30.66 ± 12.50 and 56.88 ± 21.58 dB, respectively. The hearing thresholds of the smokers at 4, 8 and 12 kHz frequencies were significantly (p5 years showed higher level of auditory threshold (62.16 ± 19.87 dB at 12 kHz frequency compared with that (41.52 ± 19.21 dB of the subjects smoked for 1-5 years and the difference in auditory thresholds was statistically significant (p<0.0002. In this study, the Brinkman Index (BI of smokers was from 6 to 440 and the adjusted odds ratio showed a positive correlation between hearing loss and smoking when adjusted for age and body mass index (BMI. In addition, age, but not BMI, also played positive role on hearing impairment at all frequencies. Thus, these findings suggested that cigarette smoking affects hearing level at all the frequencies tested but most significantly at extra higher frequencies.

    Prediction models are used in a variety of medical domains, and they are frequently built from experience which constitutes data acquired from actual cases. This study aimed to analyze the potential of artificial neural networks and logistic regression techniques for estimation of hearing impairment among industrial workers. A total of 210 workers employed in a steel factory (in West of Iran) were selected, and their occupational exposure histories were analyzed. The hearing loss thresholds of the studied workers were determined using a calibrated audiometer. The personal noise exposures were also measured using a noise dosimeter in the workstations. Data obtained from five variables, which can influence the hearing loss, were used as input features, and the hearing loss thresholds were considered as target feature of the prediction methods. Multilayer feedforward neural networks and logistic regression were developed using MATLAB R2011a software. Based on the World Health Organization classification for the grades of hearing loss, 74.2% of the studied workers have normal hearing thresholds, 23.4% have slight hearing loss, and 2.4% have moderate hearing loss. The accuracy and kappa coefficient of the best developed neural networks for prediction of the grades of hearing loss were 88.6 and 66.30, respectively. The accuracy and kappa coefficient of the logistic regression were also 84.28 and 51.30, respectively. Neural networks could provide more accurate predictions of the hearing loss than logistic regression. The prediction method can provide reliable and comprehensible information for occupational health and medicine experts.

    Full Text Available Abstract Background Because of the increasing costs and anticipated shortage of Ear Nose and Throat (ENT specialists in the care for hearing-impaired persons, an integrated care pathway that includes direct hearing aid provision was developed. While this direct pathway is still under investigation, in a survey we examined expectations and potential barriers and facilitators towards this direct pathway, of patients and professionals involved in the pathway. Methods Two study populations were assessed: members of the health professions involved in the care pathway for hearing-impaired persons (general practitioners (GPs, hearing aid dispensers, ENT-specialists and clinical audiologists and persons with hearing complaints. We developed a comprehensive semi-structured questionnaire for the professionals, regarding expectations, barriers, facilitators and conditions for implementation. We developed two questionnaires for persons with hearing complaints, both regarding evaluations and preferences, and administered them after they had experienced two key elements of the direct pathway: the triage and the hearing aid fitting. Results On average GPs and hearing aid dispensers had positive expectations towards the direct pathway, while ENT-specialists and clinical audiologists had negative expectations. Professionals stated both barriers and facilitators towards the direct pathway. Most professionals either supported implementation of the direct pathway, provided that a number of conditions were satisfied, or did not support implementation, unless roughly the same conditions were satisfied. Professionals generally agreed on which conditions need to be satisfied. Persons with hearing complaints evaluated the present referral pathway and the new direct pathway equally. Many, especially older, participants stated however that they would still visit the GP and ENT-specialist, even when this would not be necessary for reimbursement of the hearing aid, and

Parents need to mourn the loss of the expected normally hearing child, and it is important that parents create bonds of affection with their child. Objective To conduct a postevaluation of the development and cognition of 20 candidates for cochlear implants between 1 and 13 years of age and to observe important factors in their development. Methods The following instruments were used in accordance with their individual merits: interviews with parents; the Vineland Social Maturity Scale; the Columbia Maturity Scale; free drawings; Bender and Pre-Bender testing; and pedagogical tests. Results The results are described. Conclusion Parental acceptance of a child's deafness proved to be the starting point for the child's verbal or gestural communication development, as well as for cognitive, motor, and emotional development. If the association between deafness and fine motor skills (with or without multiple disabilities undermines the development of a child's speech, it does not greatly affect communication when the child interacts with his or her peers and receives maternal stimulation. Overprotection and poor sociability make children less independent, impairs their development, and causes low self-esteem. Further observational studies are warranted to determine how cochlear implants contribute to patient recovery.

    Full Text Available

    Background: Cortical auditory evoked potentials (CAEPs are an emerging tool for hearing aid fitting evaluation in young children who cannot provide reliable behavioral feedback. It is therefore useful to determine the relationship between the sensation level of speech sounds and the detection sensitivity of CAEPs.

    Design and methods: Twenty-five sensorineurally hearing impaired infants with an age range of 8 to 30 months were tested once, 18 aided and 7 unaided. First, behavioral thresholds of speech stimuli /m/, /g/, and /t/ were determined using visual reinforcement orientation audiometry (VROA. Afterwards, the same speech stimuli were presented at 55, 65, and 75 dB SPL, and CAEP recordings were made. An automatic statistical detection paradigm was used for CAEP detection.

    Results: For sensation levels above 0, 10, and 20 dB respectively, detection sensitivities were equal to 72 ± 10, 75 ± 10, and 78 ± 12%. In 79% of the cases, automatic detection p-values became smaller when the sensation level was increased by 10 dB.

    Conclusions: The results of this study suggest that the presence or absence of CAEPs can provide some indication of the audibility of a speech sound for infants with sensorineural hearing loss. The detection of a CAEP provides confidence, to a degree commensurate with the detection probability, that the infant is detecting that sound at the level presented. When testing infants where the audibility of speech sounds has not been established behaviorally, the lack of a cortical response indicates the possibility, but by no means a certainty, that the sensation level is 10 dB or less.

    The objectives of this research were to 1) summarize the available evidence on the impact of hearing loss on quality of life (QOL) among U.S. active-duty service members, 2) describe the QOL instruments that have been used to quantify the impact of hearing loss on quality of life, 3) examine national population-level secondary databases and report on their utility for studying the impact of hearing loss on QOL among active-duty service members, and 4) provide recommendations for future studies that seek to quantify the impact of hearing loss in this population. There is a lack of literature that addresses the intersection of hearing impairment, the military population, and quality of life measures. For audiological research, U.S. military personnel offer a unique research population, as they are exposed to noise levels and blast environments that are highly unusual in civilian work settings and can serve as a model population for studying the impact on QOL associated with these conditions. Our team recommends conducting a study on the active-duty service member population using a measurement instrument suitable for determining decreases in QOL specifically due to hearing loss.

    Usher syndrome is rare genetic disorder impairing two human senses, hearing and vision, with the characteristic late onset of vision loss. This syndrome is divided into three types. In all cases, the vision loss is postlingual, while loss of hearing is usually prelingual. The vestibular functions may also be disturbed in Usher type 1 and sometimes in type 3. Vestibular areflexia is helpful in making a proper diagnosis of the syndrome, but, often, the syndrome is misdiagnosed as a nonsyndromic hearing loss. Here, we present a Polish family with hearing loss, which was clinically classified as nonsyndromic. After excluding mutations in the DFNB1 locus, we implemented the next-generation sequencing method and revealed that hearing loss was syndromic and mutations in the USH2A gene indicate Usher syndrome. This research highlights the importance of molecular analysis in establishing a clinical diagnosis of congenital hearing loss.

    Disease or damage of the vestibular sense organs cause a range of distressing symptoms and functional problems that could include loss of balance, gaze instability, disorientation, and dizziness. A novel computer-based rehabilitation system with therapeutic gaming application has been developed. This method allows different gaze and head movement exercises to be coupled to a wide range of inexpensive, commercial computer games. It can be used in standing, and thus graded balance demands using a sponge pad can be incorporated into the program. A case series pre- and postintervention study was conducted of nine adults diagnosed with peripheral vestibular dysfunction who received a 12-week home rehabilitation program. The feasibility and usability of the home computer-based therapeutic program were established. Study findings revealed that using head rotation to interact with computer games, when coupled to demanding balance conditions, resulted in significant improvements in standing balance, dynamic visual acuity, gaze control, and walking performance. Perception of dizziness as measured by the Dizziness Handicap Inventory also decreased significantly. These preliminary findings provide support that a low-cost home game-based exercise program is well suited to train standing balance and gaze control (with active and passive head motion).

    Full Text Available Tectorial membrane, an extracellular matrix of the cochlea, plays a crucial role in the transmission of sound to the sensory hair cells. Alpha-tectorin is the most important noncollagenous component of the tectorial membrane and the otolith membrane in the maculae of the vestibular system. Defects in TECTA, the gene encodes alpha-tectorin, are cause of both dominant (DFNA8/12 and recessive (DFNB21 forms of deafness. Here, we report a three-generation Chinese family characterized by prelingual progressive sensorineural hearing impairment. We mapped the disease locus to chromosome 11q23-24 region, overlapping with the DFNA8/12 locus. Sequencing of candidate gene TECTA revealed a heterozygous c.5945C>A substitution in exon 19, causing amino acid substitution of Ala to Asp at a conservative position 1982. The A1982D substitution is consistent with hearing loss in this Chinese family and has not been found in 200 random control chromosomes. To our knowledge, this is the first TECTA mutation identified in Chinese population. Our data provides additional molecular and clinical information for establishing a better genotype-phenotype understanding of DFNA8/12.

    Hearing impairment is a major limitation in communication, and it can obstruct psychological development, development of social skills and motor development. Hearing impairment is the third most common contemporary chronic health condition, and it has become a public health problem. The effectiveness of problem solving in everyday life and in emergency situations depends greatly on the amount and quality of the motor programs. Therefore, it is evident that the normal motor development in persons with hearing impairment is essential for everyday life. The aim of this research is to analyze the available information pertaining to motor skills of hearing impaired children both with and without a cochlear implant (CI) and to analyze possibilities of influencing their motor skills. The relevant studies on motor skills of hearing impaired children both with and without CI were obtained by an extensive computer search of various databases using special keywords and extraction with respect to certain criteria, resulting in 22 studies. The overall results of this systematic review indicate that the children with hearing impairment exhibit suboptimal levels of motor skills especially balance. Very few studies compared children with hearing impairment with CI units and without CI units and the results of those studies are quite contradictory. Numerous studies have confirmed that the regular and appropriate physical exercise can improve motor skills of children with hearing impairment, especially balance. The fact that the development of motor skills is crucial for the child's interaction with the outside world, action, perception and acquisition of academic skills and other skills necessary for life shows the importance of motor skills development for children with hearing impairment.

    There is conflicting evidence about the relative benefit of slow- and fast- acting compression for speech intelligibility. It has been hypothesized tha tfast-acting compression improves audibility at low signal-to-noise ratios (SNRs) but may distort the speech envelope at higher SNRs. The present...... intelligibility benefit of fast-acting compression was found in both the quiet and the noisy conditions for the lower speech levels. No negative effects of fast-acting compression were observed when the speech level exceeded the level of the noise. These findings suggest that fast-acting compression provides...... study investigated the effects of compression with nearly instantaneous attack time but either fast (10 ms) or slow (500 ms) release times on consonant identification in hearing-impaired listeners.

    Hybrid or electro-acoustic stimulation (EAS) cochlear implants (CIs) are designed to provide high-frequency electric hearing together with residual low-frequency acoustic hearing. However, 30-50% of EAS CI recipients lose residual hearing after implantation. The objective of this study was to determine the mechanisms of EAS-induced hearing loss in an animal model with high-frequency hearing loss. Guinea pigs were exposed to 24 h of noise (12-24 kHz at 116 dB) to induce a high-frequency hearing loss. After recovery, two groups of animals were implanted (n = 6 per group), with one group receiving chronic acoustic and electric stimulation for 10 weeks, and the other group receiving no stimulation during this time frame. A third group (n = 6) was not implanted, but received chronic acoustic stimulation. Auditory brainstem responses were recorded biweekly to monitor changes in hearing. The organ of Corti was immunolabeled with phalloidin, anti-CtBP2, and anti-GluR2 to quantify hair cells, ribbons and post-synaptic receptors. The lateral wall was immunolabeled with phalloidin and lectin to quantify stria vascularis capillary diameters. Bimodal or trimodal diameter distributions were observed; the number and location of peaks were objectively determined using the Aikake Information Criterion and Expectation Maximization algorithm. Noise exposure led to immediate hearing loss at 16-32 kHz for all groups. Cochlear implantation led to additional hearing loss at 4-8 kHz; this hearing loss was negatively and positively correlated with minimum and maximum peaks of the bimodal or trimodal distributions of stria vascularis capillary diameters, respectively. After chronic stimulation, no significant group changes in thresholds were seen; however, elevated thresholds at 1 kHz in implanted, stimulated animals were significantly correlated with decreased presynaptic ribbon and postsynaptic receptor counts. Inner and outer hair cell counts did not differ between groups and

    A real-time hand-sized portable device that slows speech speed without changing the pitch is proposed for hearing impairment. By using this device, people can listen to fast speech at a comfortable speed. A combination of solid-state memory recording and real-time digital signal processing with a single chip processor enables this unique function. A simplified pitchsynchronous, time-scale-modification algorithm is proposed to minimize the complexity of the DSP operation. Unlike the traditional algorithm, this dynamic-processing algorithm reduces distortion even when the expansion rate is only just above 1. Seven out of 10 elderly hearing-impaired listeners showed improvement in a sentence recognition test when using speech-rate conversion with the largest expansion rate, although no improvement was observed in a word recognition test. Some subjects who showed large improvement had limited auditory temporal resolution, but the correlation was not significant. The results suggest that, unlike conventional hearing aids, this device can be used to overcome the deterioration of auditory ability by improving the transfer of information from short-term (echoic) memory into a more stable memory trace in the human auditory system.

    The aims of the current n200 study were to assess the structural relations between three classes of test variables (i.e. HEARING, COGNITION and aided speech-in-noise OUTCOMES) and to describe the theoretical implications of these relations for the Ease of Language Understanding (ELU) model. Participants were 200 hard-of-hearing hearing-aid users, with a mean age of 60.8 years. Forty-three percent were females and the mean hearing threshold in the better ear was 37.4 dB HL. LEVEL1 factor analyses extracted one factor per test and/or cognitive function based on a priori conceptualizations. The more abstract LEVEL 2 factor analyses were performed separately for the three classes of test variables. The HEARING test variables resulted in two LEVEL 2 factors, which we labelled SENSITIVITY and TEMPORAL FINE STRUCTURE; the COGNITIVE variables in one COGNITION factor only, and OUTCOMES in two factors, NO CONTEXT and CONTEXT. COGNITION predicted the NO CONTEXT factor to a stronger extent than the CONTEXT outcome factor. TEMPORAL FINE STRUCTURE and SENSITIVITY were associated with COGNITION and all three contributed significantly and independently to especially the NO CONTEXT outcome scores (R(2) = 0.40). All LEVEL 2 factors are important theoretically as well as for clinical assessment.

    To evaluate the possible effects of extracorporeal shock wave lithotripsy (ESWL) on the hearing status of the patients in this prospective controlled study. A total of 40 patients with normal hearing function were included to the study. We had 20 patients each in the study group and control group. The treatment parameters were standardized in all 3 sessions in which a total of 3000 shock waves with a rate of 90/min along with a total energy value of 126 J at the fourth energy level have been applied (Dornier Compact Sigma, Medtech, Germany). In addition to the testing of hearing functions and possible cochlear impairment by Transient Evoked Otoacoustic Emissions test at 1.0, 1.4, 2.0, 2.8, and 4.0 kHz frequencies, complications such as ear pain, tinnitus, and hearing loss have been well evaluated in each patient before the procedure and 2 hours and 1 month after the completion of the third session of ESWL in the study group. The same evaluation procedures were performed before the study and after 7-weeks in the control group. Regarding Transient Evoked Otoacoustic Emissions data obtained in study group and control group patients, there was no significant alteration in values obtained after ESWL when compared with the values before the procedure. A well-planned ESWL procedure is a safe and effective treatment in urinary stones and causes no detectable harmful effect on the hearing function of treated patients. Copyright © 2014 Elsevier Inc.

    Full Text Available Background and Aim: The majority of people experience problems and stressors, such as job layoffs and illnesses during their lives. However, the way people cope with stress varies. According to previous research, use of effective coping strategies can significantly reduce stress and tension. The aim of the present study was to investigate the effectiveness of stress coping strategies on hearing-impaired students.Methods: This is a quasi-experimental study with pre-test, post-test, and control group. The sample consisted of 40 hearing-impaired male students of guidance and high schools of the city of Sari, Iran, in the years 2010 and 2011. They were randomly selected and assigned to two experimental and control groups (n=20. The data collection tool was the General Health Questionnaire-28. The experimental group was administered eight sessions of stress coping strategies based on cognitive-behavioral techniques two hours weekly. Data were analyzed using statistical indices including mean, standard deviation, and two-way analysis of variance.Results: There was a significant difference between the pre-test and post-test scores in the subscales of somatic symptoms, anxiety and insomnia, depression, and social function (p<0.05. Moreover, after the eight sessions the rate of general health of the experimental group was higher than the control group.Conclusion: Stress coping strategies based on cognitive-behavioral techniques increased the general health of hearing-impaired people. Therefore, stress management training should be developed and expanded as an appropriate intervention.

    Full Text Available The objective of the current study was to understand the added effects of having a sensory impairment (vision and/or hearing impairment in combination with cognitive impairment with respect to health-related outcomes among older adults (65+ years old receiving home care or residing in a long-term care (LTC facility in Ontario, Canada.Cross-sectional analyses were conducted using existing data collected with one of two interRAI assessments, one for home care (n = 291,824 and one for LTC (n = 110,578. Items in the assessments were used to identify clients with single sensory impairments (e.g., vision only [VI], hearing only [HI], dual sensory impairment (DSI; i.e., vision and hearing and those with cognitive impairment (CI. We defined seven mutually exclusive groups based on the presence of single or combined impairments.The rate of people having all three impairments (i.e., CI+DSI was 21.3% in home care and 29.2% in LTC. Across the seven groups, individuals with all three impairments were the most likely to report loneliness, to have a reduction in social engagement, and to experience reduced independence in their activities of daily living (ADLs and instrumental ADLs (IADLs. Communication challenges were highly prevalent in this group, at 38.0% in home care and 49.2% in LTC. In both care settings, communication difficulties were more common in the CI+DSI group versus the CI-alone group.The presence of combined sensory and cognitive impairments is high among older adults in these two care settings and having all three impairments is associated with higher rates of negative outcomes than the rates for those having CI alone. There is a rising imperative for all health care professionals to recognize the potential presence of hearing, vision and cognitive impairments in those for whom they provide care, to ensure that basic screening occurs and to use those results to inform care plans.

    It is becoming increasingly important to have reliable and valid questionnaires. This becomes especially important when evaluating hearing loss. the "Effectiveness of Auditory Rehabilitation" (EAR) questionnaire for the Spanish-speaking population. This instrument assesses quality of life and hearing aspects in patients using hearing aids. Cross-sectional validation study. A cultural adaptation through the use of English to Spanish translations and re-translations was carried out. The validity and reliability of the newly adapted instrument were evaluated. A total of 69 individuals (44 older adults and 25 younger adults) were examined. The pure-tone averages (PTA, 500, 1,000 and 2,000 Hz) were 47.3 dB HL and 47.1 dB HL for the left and right ears, respectively. The mean maximum speech discrimination in silence for monosyllables were 83.3% and 82.9% for the left and right ears, respectively. Internal consistency presented Cronbach alpha values of 0.85 and 0.77 for the internal and external dimensions, respectively. The intraclass correlation coefficients were 0.80 for the internal module and 0.85 for the external module. Construct validity reported a correlation coefficient of 0.71 at baseline and 0.76 at 3 months after the initial assessment for the internal module, and 0.62 at baseline and 0.74 at 3 months after the initial assessment for the external module. The size effects were 1.3 and 1.1 for the internal and external modules, respectively. The Spanish version of the EAR questionnaire seems to be a reliable and valid instrument. The evaluation of audiological aspects, as well as aspects relating to aesthetics and comfort are the main strengths of this instrument. Finally, the EAR scale is more sensitive to change than other scales. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    Hearing loss is the third most common chronic physical condition in the United States, and is more prevalent than diabetes or cancer (1). Occupational hearing loss, primarily caused by high noise exposure, is the most common U.S. work-related illness (2). Approximately 22 million U.S. workers are exposed to hazardous occupational noise (3). CDC compared the prevalence of hearing impairment within nine U.S. industry sectors using 1,413,789 noise-exposed worker audiograms from CDC's National Institute for Occupational Safety and Health (NIOSH) Occupational Hearing Loss Surveillance Project (4). CDC estimated the prevalence at six hearing impairment levels, measured in the better ear, and the impact on quality of life expressed as annual disability-adjusted life years (DALYs), as defined by the 2013 Global Burden of Disease (GBD) Study (5). The mining sector had the highest prevalence of workers with any hearing impairment, and with moderate or worse impairment, followed by the construction and manufacturing sectors. Hearing loss prevention, and early detection and intervention to avoid additional hearing loss, are critical to preserve worker quality of life.

    Full Text Available Objective: A research was conducted to assess the phonological awareness in hearing-impaired children in comparison to normal children. In this context, we discussed about the ability of these children in identification of rhyme and word segmentation to syllables. Method and Material: The sample of this study is composed of 320 children, 160 normal & 160 hearing-impaired with a hearing-loss. Of over 70 dB, studying in the 1st t 4th grade of the primary schools in Tehran. They are divided into two groups at each level (20 girls & 20 boys. Results: 1 Hearing-impaired children's scores on test related to rhyme and syllable is lower as compared with normal children. 2 Hearing-impaired children are more potent on test of word segmentation to syllables in comparison to that related to rhyme, while normal children are more successful on test of word segmentation to syllables as compared with that related to rhyme. Discussion: Hearing is an important factor in phonological awareness. Formal education at special schools doesn't compensate for the hearing impairment as to development of the phonological awareness.

    Hypothyroidism is a cause of genetic and environmentally induced deafness. The sensitivity of cochlear development and function to thyroid hormone (TH) mandates understanding TH action in this sensory organ. Prop1(df) and Pou1f1(dw) mutant mice carry mutations in different pituitary transcription factors, each resulting in pituitary thyrotropin deficiency. Despite the same lack of detectable serum TH, these mutants have very different hearing abilities: Prop1(df) mutants are mildly affected, while Pou1f1(dw) mutants are completely deaf. Genetic studies show that this difference is attributable to the genetic backgrounds. Using embryo transfer, we discovered that factors intrinsic to the fetus are the major contributor to this difference, not maternal effects. We analyzed Prop1(df) mutants to identify processes in cochlear development that are disrupted in other hypothyroid animal models but protected in Prop1(df) mutants by the genetic background. The development of outer hair cell (OHC) function is delayed, but Prestin and KCNQ4 immunostaining appear normal in mature Prop1(df) mutants. The endocochlear potential and KCNJ10 immunostaining in the stria vascularis are indistinguishable from wild type, and no differences in neurofilament or synaptophysin staining are evident in Prop1(df) mutants. The synaptic vesicle protein otoferlin normally shifts expression from OHC to IHC as temporary afferent fibers beneath the OHC regress postnatally. Prop1(df) mutants exhibit persistent, abnormal expression of otoferlin in apical OHC, suggesting delayed maturation of synaptic function. Thus, the genetic background of Prop1(df) mutants is remarkably protective for most functions affected in other hypothyroid mice. The Prop1(df) mutant is an attractive model for identifying the genes that protect against deafness.

    Full Text Available Background: Chronic suppurative otitis media (CSOM is one of the leading causes of preventable disabling hearing impairment (DHI in developing countries. Early detection and management complements advances made in other survival programs, improves work capacity, and enhances learning opportunities for school children. We aimed to determine the prevalence of CSOM and associated DHI among school children aged six to 16 years in Socotra Island, Yemen. Methods: We conducted a cross-sectional community-based survey, from 20 April 2011 to 20 June 2011. The study procedures involved completing a questionnaire, an otoscopic ear examination, an audiometric test of hearing, and tuning fork tests for the type of DHI. Results: A total of 686 children were interviewed and examined for CSOM and associated DHI of CSOM cases. The prevalence of CSOM was 7.4%, (95% CI 5.5–9.4. CSOM status was significantly associated with DHI (p=0.001, but no significant associations were found between demographic characteristics and CSOM status. Logistic regression identified four significant independent contributing factors: history of ear discharge in the last 12 months (odds ratio (OR 7.8, 95% CI 3.9–15.6; swimming in local pools (OR 6.0, 95% CI 1.4–25.4; recurrent respiratory tract infection more than three times per year (OR 5.3, 95% CI 2.5–11.0; and overcrowding with more than three families per house (OR 4.4, 95% CI 1.7–11.5. . Conclusion: The burden of CSOM in the children studied indicates a high level of DHI in these communities within Yemen. A history of ear discharge, swimming in local pools, recurrent respiratory infections, and overcrowded housing were the strongest predictors for CSOM. There is a need for better ear care and screening programs for early detection and management of this disease.

    Visual impairment (VI) and hearing impairment (HI) are the two most common types of sensory disability encountered clinically. However, VI and HI result in different limitations in daily life. We assessed the level of functioning in patients with VI or HI based on the International Classification of Functioning, Disability, and Health. This nationwide, cross-sectional study included 312 people with VI and 540 people with HI. Each participant's degree of functioning and disability was evaluated using the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0). The standardized WHODAS 2.0 scores ranged from 0 (least difficulty) to 100 (most difficulty). Patients with VI and those with HI had a mean (±standard error) 32-item WHODAS 2.0 score of 42.4 ± 2.9 and 27.1 ± 1.6, respectively. The degree of restriction was positively related to the level of VI. Specifically, the patients with VI and a WHODAS 2.0 score of 33.7-35.3 or higher were likely to experience barriers to accessing mobility products, communication products, and education products. Furthermore, patients with a score of 42.9 or higher might experience barriers to accessing ingestion products and living products. WHODAS 2.0 scores are strongly correlated with the severity of VI. Mild VI should be targeted for treatment and referral as early as possible. Compared with the patients with HI, the patients with VI more frequently experience barriers to accessing environmental factors. Copyright © 2017. Published by Elsevier Taiwan LLC.

    Full Text Available Abstract Background The molecular etiology of hearing impairment in Chinese has not been thoroughly investigated. Study of GJB2 gene revealed that 30.4% of the patients with hearing loss in Inner Mongolia carried GJB2 mutations. The SLC26A4 gene mutations and relevant phenotype are analyzed in this study. Methods One hundred and thirty-five deaf patients were included. The coding exons of SLC26A4 gene were sequence analyzed in 111 patients, not including 22 patients carrying bi-allelic GJB2 mutations or one patient carrying a known GJB2 dominant mutation as well as one patient with mtDNA 1555A>G mutation. All patients with SLC26A4 mutations or variants were subjected to high resolution temporal bone CT scan and those with confirmed enlarged vestibular aqueduct and/or other inner ear malformation were then given further ultrasound scan of thyroid and thyroid hormone assays. Results Twenty-six patients (19.26%, 26/135 were found carrying SLC26A4 mutation. Among them, 17 patients with bi-allelic SLC26A4 mutations were all confirmed to have EVA or other inner ear malformation by CT scan. Nine patients were heterozygous for one SLC26A4 mutation, including 3 confirmed to be EVA or EVA and Mondini dysplasia by CT scan. The most common mutation, IVS7-2A>G, accounted for 58.14% (25/43 of all SLC26A4 mutant alleles. The shape and function of thyroid were confirmed to be normal by thyroid ultrasound scan and thyroid hormone assays in 19 of the 20 patients with EVA or other inner ear malformation except one who had cystoid change in the right side of thyroid. No Pendred syndrome was diagnosed. Conclusion In Inner Mongolia, China, mutations in SLC26A4 gene account for about 12.6% (17/135 of the patients with hearing loss. Together with GJB2 (23/135, SLC26A4 are the two most commonly mutated genes causing deafness in this region. Pendred syndrome is not detected in this deaf population.

    Working memory is considered to influence a range of linguistic skills, i.e. vocabulary acquisition, sentence comprehension and reading. Several studies have pointed to limitations of working memory in children with specific language impairment. Few studies, however, have explored the role of working memory for language deficits in children with hearing impairment. The first aim was to compare children with mild-to-moderate bilateral sensorineural hearing impairment, children with a preschool diagnosis of specific language impairment and children with normal language development, aged 9-12 years, for language and working memory. The special focus was on the role of working memory in learning new words for primary school age children. The assessment of working memory included tests of phonological short-term memory and complex working memory. Novel word learning was assessed according to the methods of. In addition, a range of language tests was used to assess language comprehension, output phonology and reading. Children with hearing impairment performed significantly better than children with a preschool diagnosis of specific language impairment on tasks assessing novel word learning, complex working memory, sentence comprehension and reading accuracy. No significant correlation was found between phonological short-term memory and novel word learning in any group. The best predictor of novel word learning in children with specific language impairment and in children with hearing impairment was complex working memory. Furthermore, there was a close relationship between complex working memory and language in children with a preschool diagnosis of specific language impairment but not in children with hearing impairment. Complex working memory seems to play a significant role in vocabulary acquisition in primary school age children. The interpretation is that the results support theories suggesting a weakened influence of phonological short-term memory on novel word

  5. Students with hearing impairment at a South African university: Self-identity and disclosure

    Science.gov (United States)

    2016-01-01

    Background A growing number of students with hearing loss are being granted access to higher education in South Africa due to the adoption of inclusive educational policies. However, available statistics indicate that participation by students with hearing impairments in higher education remains low and research suggests that support provisioning for those who do gain access is inadequate. Objectives This article aims to illustrate that the assumed self-identity of students with hearing impairment influences their choice to disclose their disability. The choice not to disclose their hearing loss prevents them from accessing the necessary reasonable accommodations and this in turn may affect their eventual educational success. Method Reported here is a qualitative descriptive case study at a South African university. Purposive sampling methods were employed. Data were gathered from in-depth interviews with seven students with hearing impairment ranging from moderate to profound, using spoken language. Constructivist grounded theory was used as an approach to the process of generating and transforming the data, as well as the construction of theory. Findings All the student participants identified as having a hearing rather than a D/deaf identity cultural paradigm and viewed themselves as ‘normal’. Linked to this was their unwillingness to disclose their hearing impairment and thus access support. Conclusion It is crucially important for academic, support and administrative staff to be aware of both the assumed ‘hearing’ identity and therefore subsequent non-disclosure practices of students with a hearing impairment using the oral method of communication. Universities need to put measures in place to encourage students to voluntarily disclose their hearing impairment in order to provide more targeted teaching and learning support. This could lead to improved educational outcomes for students. PMID:28730053

    This paper presents the results of an assessment of speech discrimination by hearing-impaired listeners (sensori-neural, conductive, and mixed groups) under binaural free-field listening in the presence of background noise. Subjects with pure-tone thresholds greater than 20 dB in 0.5, 1.0 and 2.0 kHz were presented with a version of the W-22 list of phonetically balanced words under three conditions: (1) 'quiet', with the chamber noise below 28 dB and speech at 60 dB; (2) at a constant S/N ratio of +10 dB, and with a background white noise at 70 dB; and (3) same as condition (2), but with the background noise at 80 dB. The mean speech discrimination scores decreased significantly with noise in all groups. However, the decrease in binaural speech discrimination scores with an increase in hearing impairment was less for material presented under the noise conditions than for the material presented in quiet.

    The human ortholog of the gene responsible for audiogenic seizure susceptibility in Frings and BUB/BnJ mice (mouse gene symbol Mass1) recently was shown to underlie Usher syndrome type IIC (USH2C). Here we report that the Mass1frings mutation is responsible for the early onset hearing impairment of BUB/BnJ mice. We found highly significant linkage of Mass1 with ABR threshold variation among mice from two backcrosses involving BUB/BnJ mice with mice of strains CAST/EiJ and MOLD/RkJ. We also show an additive effect of the Cdh23 locus in modulating the progression of hearing loss in backcross mice. Together, these two loci account for more than 70% of the total ABR threshold variation among the backcross mice at all ages. The modifying effect of the strain-specific Cdh23ahl variant may account for the hearing and audiogenic seizure differences observed between Frings and BUB/BnJ mice, which share the Mass1frings mutation. During postnatal cochlear development in BUB/BnJ mice, stereocilia bundles develop abnormally and remain immature and splayed into adulthood, corresponding with the early onset hearing impairment associated with Mass1frings. Progressive base–apex hair cell degeneration occurs at older ages, corresponding with the age-related hearing loss associated with Cdh23ahl. The molecular basis and pathophysiology of hearing loss suggest BUB/BnJ and Frings mice as models to study cellular and molecular mechanisms underlying USH2C auditory pathology. PMID:15820310

    Full Text Available Communication impairments such as aphasia and apraxia can follow brain injury and result in limitation of an individual's participation in social interactions, and capacity to convey needs and desires. Our research group developed a computerised treatment programme which is based on neuroscientific principles of speech production (Varley and Whiteside, 2001; Varley, 2010; Whiteside and Varley, 1998 and has been shown to improve communication in people with apraxia and aphasia (Dyson et al., 2009; Varley et al., 2009. Investigations of treatment efficacy have presented challenges in study design, effect measurement and statistical analysis which are likely to be shared by other researchers in the wider field of cognitive neurorehabilitation evaluation. Several key factors define neurocognitively based therapies, and differentiate them and their evaluation from other forms of medical intervention. These include: (1 inability to blind patients to the content of the treatment and control procedures; (2 neurocognitive changes that are more permanent than pharmacological treatments on which many medical study designs are based; and (3 the semi-permanence of therapeutic effects means that new baselines are set throughout the course of a given treatment study, against which comparative interventions or long term retention effects must be measured. This article examines key issues in study design, effect measurement and data analysis in relation to the rehabilitation of patients undergoing treatment for apraxia of speech. Results from our research support a case for the use of multiperiod, multiphase cross-over design with specific computational adjustments and statistical considerations. The paper provides researchers in the field with a methodologically feasible and statistically viable alternative to other designs used in rehabilitation sciences.

    To evaluate hearing impairment in 2 common genetic subtypes of Usher syndrome, USH1B and USH2A. Cross-sectional analysis of hearing threshold related to age in patients with genotypes determined by linkage and mutation analysis. Otolaryngology department, university referral center. Nineteen patients with USH1B and 27 with USH2A were examined. All participants were living in the Netherlands and Belgium. Pure tone audiometry of the best ear at last visit. The patients with USH1B had residual hearing without age dependence, with minimum thresholds of 80, 95, and 120 dB at 0.25, 0.5, and 1 to 2 kHz, respectively. Mean thresholds of patients with USH2A were about 45 to 55 dB better than these minimum values. Distinctive audiographic features of patients with USH2A were maximum hearing thresholds of 70, 80, and 100 dB at 0.25, 0.5, and 1 kHz, respectively, only at younger than 40 years. Progression of hearing impairment in USH2A was 0.7 dB/y on average for 0.25 to 4 kHz and could not be explained by presbyacusis alone. The USH1B and USH2A can be easily distinguished by hearing impairment at younger than 40 years at the low frequencies. Hearing impairment in our patients with USH2A could be characterized as progressive.

    With the physical, emotional and cognitive effects of senility, elderly people, especially those with impaired hearing, need rehabilitation for improving their life conditions. Hearing aids are frequently used to improve their daily life communications and activities. The aim of this study was to report the cognitive and psychological benefits of using hearing aids by the elderly people, over the age of 65. This was a prospective, single-arm interventional study in 34 elderly subjects with hearing impairment who answered the geriatric depression scale-short form (GDS) questionnaire and the mini mental state examination (MMSE) test, prior to, and 3 months following the use of hearing aid, after obtaining the patients' consent to participate in study. Patients with evidence of focal neurological loss with clinical examination, a confusional state, sudden hear loss and severe tinnitus were not included in the study. Scores of the effects of hearing aids on mood and cognitive functions were compared for each subject, before and after, and between males and females. After 3 months of using a hearing aid, all patients showed a significant improvement of the psychosocial and cognitive conditions, and all of them showed betterment of their problems, i.e., the social communication and exchanging information. In conclusion, for the elderly people with the effects of hearing aids in presbycusis and due to the significant improvement in psychological state and mental functions, using and being adaptable to hearing aids is a good solution.

    Full Text Available Hearing impairment may affect children’s communication skills, social development, and educational achievement. Little is known about the prevalence of hearing impairment among Chinese children. Data were taken from the 2006 second China National Survey on Disability (CNSD. Hearing impairment was defined as moderate (41–60 dB HL, severe (61–80 dB HL, profound (81–90 dB HL, or complete (>91 dB HL. Logistic regression was used to estimate the odds ratio (OR and 95% confidence intervals (CI. A weighted number of 567,915 hearing impairment children were identified, yielding a prevalence of 17.49 per 10,000 people (95% CI: 16.90–18.08, with prevention or treatment options possible for 64.6% of hearing impairment children. The main causes of hearing impairment were hereditary, tympanitis, and drug intoxication. Illiteracy in one or both parents (mother: OR = 1.388, 95% CI: 1.125–1.714, p < 0.0001; father: OR = 1.537, 95% CI: 1.152–2.049, p < 0.0001 relative to no school or primary school, annual family income lower than national average (OR = 1.323, 95% CI: 1.044–1.675, p = 0.0203, relative to higher than national average, household size larger than three people (OR = 1.432, 95% CI: 1.164–1.762, p = 0.0007, relative to smaller than three people and single-mother family (OR = 2.056, 95% CI: 1.390–3.042, p = 0.0176, relative to intact family were the independence risk factors for hearing impairment among Chinese children. Lower annual family income, male children, larger household size, single-mother family, and lower levels of maternal and paternal education were independent risk factors for hearing impairment for Chinese children. Further studies on hearing impairment prevention and the relationship between parental social factors and the risk of hearing impairment are needed.

    Balance function has been reported to be worse in ADHD children than in their normal peers. The present study hypothesized that an improvement in balance could result in better cognitive performance in children with ADHD and concurrent vestibular impairment. This study was designed to evaluate the effects of comprehensive vestibular rehabilitation therapy on the cognitive performance of children with combined ADHD and concurrent vestibular impairment. Subject were 54 children with combined ADHD. Those with severe vestibular impairment (n=33) were randomly assigned to two groups that were matched for age. A rehabilitation program comprising overall balance and gate, postural stability, and eye movement exercises was assigned to the intervention group. Subjects in the control group received no intervention for the same time period. Intervention was administered twice weekly for 12 weeks. Choice reaction time (CRT) and spatial working memory (SWM) subtypes of the Cambridge Neuropsychological Test Automated Battery (CANTAB) were completed pre- and post-intervention to determine the effects of vestibular rehabilitation on the cognitive performance of the subjects with ADHD and concurrent vestibular impairment. ANCOVA was used to compare the test results of the intervention and control group post-test. The percentage of correct trial scores for the CRT achieved by the intervention group post-test increased significantly compared to those of the control group (p=0.029). The CRT mean latency scores were significantly prolonged in the intervention group following intervention (p=0.007) compared to the control group. No significant change was found in spatial functioning of the subjects with ADHD following 12 weeks of intervention (p>0.05). The study highlights the effect of vestibular rehabilitation on the cognitive performance of children with combined ADHD and concurrent vestibular disorder. The findings indicate that attention can be affected by early vestibular

    Hearing loss is a common sensory impairment. Several genetic loci or genes responsible for non-syndrome hearing loss have been identified, including the well-known deafness genes GJB2, MT-RNR1 and SLC26A4. MYO3A belongs to the myosin superfamily. Previously only three mutations in this gene have been found in an Isreali family with DFNB30, in which patients demonstrated progressive hearing loss. In this study, we characterized a consanguineous Kazakh family with congenital hearing loss. By targeted sequence capture and next-generation sequencing, we identified a homozygous mutation and did bioinformatics analysis to this mutation. A homozygous mutation, MYO3A:c.1841C>T (p.S614F), was identified to be responsible for the disease. Ser614 is located in the motor domain of MYO3A that is highly conserved among different species. Molecular modeling predicts that the conserved Ser614 may play an important role in maintaining the stability of β-sheet and the interaction between neighboring β-strand. This is the second report on MYO3A mutations in deafness and the first report in China. The finding help facilitate establishing a better relationship between MYO3A mutation and hearing phenotypes.

    People with severe neurological impairments face many challenges in sensorimotor functions and communication with the environment; therefore they have increased demand for advanced, adaptive and personalized rehabilitation. During the last several decades, numerous studies have developed brain–computer interfaces (BCIs) with the goals ranging from providing means of communication to functional rehabilitation. Here we review the research on non-invasive, electroencephalography (EEG)-based BCI systems for communication and rehabilitation. We focus on the approaches intended to help severely paralyzed and locked-in patients regain communication using three different BCI modalities: slow cortical potentials, sensorimotor rhythms and P300 potentials, as operational mechanisms. We also review BCI systems for restoration of motor function in patients with spinal cord injury and chronic stroke. We discuss the advantages and limitations of these approaches and the challenges that need to be addressed in the future. PMID:29472849

    Full Text Available The present study proposed a descriptive analysis of sociodemographic and family variables, as well as risky sexual behaviors and sexual abuse in a sample of young Mexicans with hearing or visual impairments, examining differences based on gender and type of disability of the participants. 128 young persons (64 hearing impaired and 64 visually impaired of whom, 53.2% were male and 86.6% were single, were included in the study. The instruments used were adapted linguistically to be answered by young people with hearing disabilities, and translated into Braille for visually impaired young people. The results show that participants maintain an active sex life with a risk profile that is characterized by the early onset of sexual intercourse, lack of planning their first sexual encounter, underuse of condoms and victimization of some form of sexual abuse. The risk was higher in women and among those with visual disabilities.

    Post-stroke cognitive impairment (PSCI) lessens quality of life, restricts the rehabilitation of stroke, and increases the social and economic burden stroke imposes on patients and their families. Therefore effective treatment is of paramount importance. However, the treatment of PSCI is very limited. The primary aim of this protocol is to propose a lower cost and more effective therapy, and to confirm the long-term effectiveness of a therapeutic regimen of Traditional Chinese Medicine (TCM) rehabilitation for PSCI. A prospective, multicenter, large sample, randomized controlled trial will be conducted. A total of 416 eligible patients will be recruited from seven inpatient and outpatient stroke rehabilitation units and randomly allocated into a therapeutic regimen of TCM rehabilitation group or cognitive training (CT) control group. The intervention period of both groups will last 12 weeks (30 minutes per day, five days per week). Primary and secondary outcomes will be measured at baseline, 12 weeks (at the end of the intervention), and 36 weeks (after the 24-week follow-up period). This protocol presents an objective design of a multicenter, large sample, randomized controlled trial that aims to put forward a lower cost and more effective therapy, and confirm the long-term effectiveness of a therapeutic regimen of TCM rehabilitation for PSCI through subjective and objective assessments, as well as highlight its economic advantages. This trial was registered with the Chinese Clinical Trial Registry (identifier: ChiCTR-TRC-14004872 ) on 23 June 2014.

    Limit of stability (LOS) is an important yet under-examined postural control ability in children with developmental coordination disorder (DCD). This study aimed to (1) compare the LOS and fall frequencies of children with and without DCD, and (2) explore the relationships between LOS parameters and falls in the DCD population. Thirty primary school-aged children with DCD and twenty age- and sex-matched typically-developing children participated in the study. Postural control ability, specifically LOS in standing, was evaluated using the LOS test. Reaction time, movement velocity, maximum excursion, end point excursion, and directional control were then calculated. Self-reported fall incidents in the previous week were also documented. Multivariate analysis of variance results revealed that children with DCD had shorter LOS maximum excursion in the backward direction compared to the control group (p=0.003). This was associated with a higher number of falls in daily life (rho=-0.556, p=0.001). No significant between-groups differences were found in other LOS-derived outcomes (p>0.05). Children with DCD had direction-specific postural control impairment, specifically, diminished LOS in the backward direction. This is related to their falls in daily life. Therefore, improving LOS should be factored into rehabilitation treatment for children with DCD. Copyright © 2015 Elsevier B.V. All rights reserved.

    This study investigated the relationship between speech perception performance in spatially complex, lateralized listening scenarios and temporal fine-structure (TFS) coding at low frequencies. Young normal-hearing (NH) and two groups of elderly hearing-impaired (HI) listeners with mild or moderate...... hearing loss above 1.5 kHz participated in the study. Speech reception thresholds (SRTs) were estimated in the presence of either speech-shaped noise, two-, four-, or eight-talker babble played reversed, or a nonreversed two-talker masker. Target audibility was ensured by applying individualized linear...... threshold nor the interaural phase difference threshold tasks showed a correlation with the SRTs or with the amount of masking release due to binaural unmasking, respectively. The results suggest that, although HI listeners with normal hearing thresholds below 1.5 kHz experienced difficulties with speech...

    Full Text Available Counseling training in graduate programs continues to be underrepresented. If parental queries are not addressed adequately, they keep visiting one doctor after another. Objective. The aim of the study is to identify maternal needs of children with hearing impairment at two stages of habilitation, that is, just after diagnosis (group I and after receiving 1 to 3 years of language therapy (group II. Methods. Two groups of mothers were asked to speak their queries about aural habilitation of their children. Queries were recorded, summarized, and categorized as per their priorities. Results. Group I mothers wanted to know about how the child would learn to listen and speak (45%, causes of hearing loss (33.7%, understanding the ear and hearing (10.2%, understanding the audiogram (7%, and coping with emotional aspects of hearing loss (5%, while group II parents had priorities concerning speech development (24.5% followed by child independence and employment (17.3%, schooling (15.6%, problem behaviors (11%, amplification device (9.4%, duration of therapy (8%, future of the child (8%, and questions about how can my child get adjusted to the “normal” world (6%. Conclusions. Culture- and language-specific materials to explain these issues need to be developed.

    Four experiments were performed to evaluate a new wearable vibrotactile speech perception aid that extracts fundamental frequency (F0) and displays the extracted F0 as a single-channel temporal or an eight-channel spatio-temporal stimulus. Specifically, we investigated the perception of intonation (i.e., question versus statement) and emphatic stress (i.e., stress on the first, second, or third word) under Visual-Alone (VA), Visual-Tactile (VT), and Tactile-Alone (TA) conditions and compared performance using the temporal and spatio-temporal vibrotactile display. Subjects were adults with normal hearing in experiments I-III and adults with severe to profound hearing impairments in experiment IV. Both versions of the vibrotactile speech perception aid successfully conveyed intonation. Vibrotactile stress information was successfully conveyed, but vibrotactile stress information did not enhance performance in VT conditions beyond performance in VA conditions. In experiment III, which involved only intonation identification, a reliable advantage for the spatio-temporal display was obtained. Differences between subject groups were obtained for intonation identification, with more accurate VT performance by those with normal hearing. Possible effects of long-term hearing status are discussed.

    Full Text Available Introduction: A hearing– impaired patient is defined as one with abnormal or reduced function in hearing resulting from an auditory disorder. The goal of any preschool and schools screening program should be to accurately indentify those children whose hearing has been impaired due to conductive and / or sensory– neural pathology. Methods: This cross– sectional descriptive study was done on 577 children (299 girls and 278 boys aged between 3–6 years at kindergartens of Yazd city from September 2005 to January 2006. The otoscopy examination, pure-tone screening and impedance study was conducted after completion of awareness form of the hearing loss existence by the parents. Results: In this study, there were 12.6% abnormal conditions of external ear canal, 34.2% abnormal tympanic membrane, 35.9% abnormal tympanograms and 13.4% hearing loss including 11.5% conductive hearing loss, 1.5% sensory-neural hearing loss and 0.5% mixed hearing loss. Conclusion: With respect to the high prevalence and negative effects of middle ear disorders in learning of preschool children, and also due to the importance of early identification and intervention of hearing loss in aural rehabilitation programs, increasing the awareness and education of people, especially parents about the effects of hearing disorders and its prevention and identification is very important

    Childhood bacterial meningitis (BM) damages hearing, but the potential of different agents to cause impairment in developing countries is poorly understood. We compared the extent of hearing impairment in BM caused by Haemophilus influenzae type b (Hib), Streptococcus pneumoniae or Neisseria meningitidis among children aged 2 months to 13 years in Luanda, Angola. Hearing of 685 ears of 351 (78%) survivors among 723 enrolled patients was tested by brainstem-evoked response audiometry on day 7 of hospitalization. The causative agent was sought by cerebrospinal fluid culture, PCR or the latex-agglutination test. Altogether, 45 (12%) of the survivors were deaf (threshold >80 dB), and 20 (6%) had a threshold of 80 dB. The incidence of any kind of hearing loss, with ≥60 dB, was 34% with Hib, 30% with S. pneumoniae, 19% with N. meningitidis and 33% with other bacteria. Examining all ears combined and using the ≥60 dB threshold, the agents showed dissimilar harm (P=0.005), Hib being the most frequent and N. meningitidis the most infrequent cause. Compared to other agents, S. pneumoniae more often caused deafness (P=0.025) and hearing impairment at ≥60 dB (P=0.017) in infants, whereas this level of hearing loss in older survivors was most commonly caused by Hib (P=0.031). BM among children in Angola is often followed by hearing impairment, but the risk depends on the agent. S. pneumoniae is a major problem among infants, whereas Hib is mainly a risk beyond 12 months. N. meningitidis impairs hearing less frequently. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    The objective of the present study was to estimate and analyse the effectiveness and labour intensity of the methods of surgical intervention for cochlear implantation. The analysis of the surgical stage of cochlear implantation was based on the examination of 2073 children and adults during the period from 1991 to 2013. The age of the patients varied between 6 months to 71 years. The cause of deafness was meningitis and an injury in 11% and 6% of the patients respectively. The cochlear implants from Advanced Bionics were inserted in 495 patients, those from Med-El in 9 ones , and from Neurelec in 20, and Nucleus devices from Cochlear in the remaining patents (n=1549) including 37 double-array electrodes and a Hybrid implant for electroacoustic correction of hearing . The implants with a straight and perimodiolar electrode were placed in a roughly equal number of the patients. The rationale for the performance of selected components of the surgical stage of cochlear implantation was developed along with the technical procedures for the purpose applied at this Centre since 1991. The original methods for the fixation and covering of the receiver-stimulator and also for the choice of the place of the electrode array insertion into the cochlea are described. They allowed to significantly decrease the frequency of complications, duration and extent of the surgical intervention as well as to reduce to a minimum post-operative manipulations.

    The aim of this study was to evaluate ethnic- and sex-specific associations between DM and hearing impairment. For this cross-sectional study using National Health and Nutrition Examination Survey in the U.S. and Korea, the total number of eligible participants included was 7081 in the U.S. and 15,704 in Korea. Hearing impairment was defined as a pure tone threshold level ≥ 25 dB. Multivariate logistic regression analysis was conducted, adjusting for age, sex, race/ethnicity, socioeconomic status, body mass index, noise exposure, smoking, hypertension, and dyslipidemia. The association between DM and hearing impairment was found to be sex-specific. The multivariate adjusted ORs of high-frequency impairment were 0.843 (95% CI, 0.524-1.356) in American men, and 1.073 (95% CI, 0.835-1.379) in Korean men, while the ORs in women from U.S. and Korea were 1.911 (95% CI, 1.244-2.935) and 1.421 (95% CI, 1.103-1.830), respectively. A subgroup analysis of each race/ethnicity among the U.S. adults showed similar results. In contrast to high-frequency impairment, there was no significant association between low-frequency impairment and DM in both men and women. Our results suggest that DM is associated with hearing impairment in only women, irrespective of race/ethnicity groups. Copyright © 2018. Published by Elsevier Inc.

    Sensorineural hearing loss typically results in a steepened loudness function and a reduced dynamic range from elevated thresholds to uncomfortably loud levels for narrowband and broadband signals. Restoring narrowband loudness perception for hearing-impaired (HI) listeners can lead to overly loud perception of broadband signals and it is unclear how binaural presentation affects loudness perception in this case. Here, loudness perception quantified by categorical loudness scaling for nine normal-hearing (NH) and ten HI listeners was compared for signals with different bandwidth and different spectral shape in monaural and in binaural conditions. For the HI listeners, frequency- and level-dependent amplification was used to match the narrowband monaural loudness functions of the NH listeners. The average loudness functions for NH and HI listeners showed good agreement for monaural broadband signals. However, HI listeners showed substantially greater loudness for binaural broadband signals than NH listeners: on average a 14.1 dB lower level was required to reach "very loud" (range 30.8 to -3.7 dB). Overall, with narrowband loudness compensation, a given binaural loudness for broadband signals above "medium loud" was reached at systematically lower levels for HI than for NH listeners. Such increased binaural loudness summation was not found for loudness categories below "medium loud" or for narrowband signals. Large individual variations in the increased loudness summation were observed and could not be explained by the audiogram or the narrowband loudness functions. Copyright © 2016 Elsevier B.V.

    The integrity of prospective memory (PM) is likely crucial for independent human behavior. PM refers to the ability to execute an intention after a certain delay. Its impaired functioning may significantly affect the correct execution of common daily activities, such as taking a pill at a certain time or complying with future plans. The results of recent studies indicate that PM is impaired pervasively and early in individuals with mild cognitive impairment (MCI) and Parkinson's disease (PD). In this study, we reviewed studies investigating the characteristics of PM disorders in these individuals and the potential for cognitive rehabilitation. The PM profiles of individuals with MCI and PD indicate that interventions aimed at enhancing the different cognitive processes underlying their PM disorders could be useful. At the current state of the art, however, no evidence-based protocols are available. Therefore, the discussion proposed here should be considered an attempt to identify some valuable perspectives for future research and interventions.

    In low income countries, deaf children are identified late due to the absence of a universal screening. Hearing impairment is a common yet neglected disability in India that leads to loss of speech and language. This qualitative study explored barriers to accessing appropriate hearing services in one city in southern India. To identify the barriers in timely management of deafness, 25 semi-structured interviews were conducted. Data were examined using Applied Thematic Analysis. Seventeen mothers of deaf children, primarily from low socioeconomic backgrounds, and eight staff members at a charitable hearing centre in Hyderabad. Barriers to accessing hearing services included failure to recognise deafness, the dominant role of elders in household decisions, belief that deafness would resolve, reassurance from a child's overall good health, lack of funds and transportation barriers to reach the centre particularly from rural areas. Parents frequently learned about services through word of mouth. The challenges to accessing appropriate services for deafness operate prior to presentation and include educational, cultural, navigational and financial barriers especially for those of lower socioeconomic status and residents of rural areas. The findings highlighted the need to raise awareness and implement wider screening programmes for early interventions.

    Prevention of hearing impairment is important because it is difficult to recover from it. Epidemiological studies have examined the risk factors for hearing impairment; however, the association between dipstick proteinuria and hearing impairment has not been previously examined. This study aimed to clarify the association between dipstick proteinuria and hearing impairment. Cross-sectional study. Office and factory workers from all over Japan. The total number of subjects was 7005. All were employees of the same company. Of these, we recruited 6192 subjects who underwent dipstick urine test and hearing test by audiometry in annual health check-ups (mean age 44.9 years, men 88.3%). Hearing tests were performed at two frequencies (1 kHz, 4 kHz) as prescribed by law in Japan. We defined the inability of subjects to respond to 30 dB at 1 kHz and/or 40 dB at 4 kHz as overall moderate hearing impairment. In addition, we defined moderate hearing impairment at 1 kHz (4 kHz) as an abnormal finding at 1 kHz (4 kHz). We examined the associations between degree of dipstick proteinuria and hearing impairment after adjustment for age, sex, body mass index, hypertension, diabetes mellitus, serum creatinine level and history of noisy work environment. Overall moderate hearing impairment was noted in 324 subjects (5.2%). Of these, 107 subjects (1.7%) had moderate hearing impairment at 1 kHz and 278 subjects (4.5%) at 4 kHz. Dipstick proteinuria was significantly associated with overall moderate hearing impairment, as well as moderate hearing impairment at both 1 kHz and 4 kHz. The prevalence of overall moderate hearing impairment among subjects with proteinuria ≥2+ was 23.5%, while that among subjects without proteinuria was 5.2% (pimpairment in Japanese workers. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    To identify possible differences in the level of externalizing behavior problems among children with and without hearing impairment and determine whether any relationship exists between this type of problem and parenting practices. The Behavior Assessment System for Children was used to evaluate externalizing variables in a sample of 118 boys and girls divided into two matched groups: 59 with hearing disorders and 59 normal-hearing controls. Significant between-group differences were found in hyperactivity, behavioral problems, and externalizing problems, but not in aggression. Significant differences were also found in various aspects of parenting styles. A model for predicting externalizing behavior problems was constructed, achieving a predicted explained variance of 50%. Significant differences do exist between adaptation levels in children with and without hearing impairment. Parenting style also plays an important role.

    Full Text Available Objective: To identify possible differences in the level of externalizing behavior problems among children with and without hearing impairment and determine whether any relationship exists between this type of problem and parenting practices. Methods: The Behavior Assessment System for Children was used to evaluate externalizing variables in a sample of 118 boys and girls divided into two matched groups: 59 with hearing disorders and 59 normal-hearing controls. Results: Significant between-group differences were found in hyperactivity, behavioral problems, and externalizing problems, but not in aggression. Significant differences were also found in various aspects of parenting styles. A model for predicting externalizing behavior problems was constructed, achieving a predicted explained variance of 50%. Conclusion: Significant differences do exist between adaptation levels in children with and without hearing impairment. Parenting style also plays an important role.

    Background: Many congenitally sensorineural hearing loss (SNHL) children and cochlear implant (CI) recipients develop near-normal language skills. However, there is a wide variation in individual outcomes following cochlear implantation, or using hearing aids. Some CI recipients or Hearing aids users never develop useable speech and oral language skills. The causes of this enormous variation in outcomes are only partly understood at the present time. So, the aim of this study was to assess th...

  19. Subjective Evaluation of Sound Quality for Normal-hearing and Hearing-i,paired Listeners

    11 hearing-impaired (HI) and 12 normal-hearing (NH) subjects have performed sound quality ratings on 6 perceptual scales (Loudness, Clarity, Sharpness, Fullness, Spaciousness and Overall judgement). The signals for the rating experiment consisted of running speech and music with or without......, but the normal-hearing group was slightly more reliable. There were significant differences between stimuli and between subjects, with stimuli affecting the ratings the most. Normal-hearing and hearing-impaired subjects showed similar trends, but normal-hearing listeners were generally more sensitive, i...

    Interacting with hearing impaired students who communicate using auditory/oral methods provides challenges and opportunities to education/outreach activities. Despite many advances in assistive technologies, these hearing impaired students will learn much less incidentally than their peers with typical hearing. In other words, they will often require repeated auditory and perhaps visual reinforcement in order to learn a new word or a new concept. This need leads to a much more deliberate and conscious interaction between educators or scientists and the students. We are reporting from a unique joint project between the Sunshine Cottage School for Deaf Children and the Southwest Research Institute (SwRI), to bring actual space research to life for hearing impaired elementary school students. During this project, we combined the unique capabilities of Deaf Education educators with the excitement and wonder of researching the northern lights. For three consecutive winters, we conducted a series of informal yet structured activities each year with fourth and fifth grade students. Our interactions went beyond typical classroom activities and readily available educational materials. Our goal was to engage and excite the students. To do so, we set up a series of interactions and mini-projects that introduced the students to actual research and actual researchers. From "meet the scientists" visits to school over a field trip to the SwRI space research facilities to observing and predicting the aurora using real-time space weather data, we engaged students in the "who" and "how" of doing research and field work in Alaska's winter. Over the course of this project, students connected with a remote school in the interior of Alaska, participated in the excitement of a NASA sounding rocket campaign in in Poker Flat, AK, skyped with researchers and students in Alaska, and made aurora predictions using NOAA real time space weather data. The highlight of the program each year was

    This overview study provides information on important phoniatric and audiological aspects of early childhood hearing and language development with the aim of presenting diagnostic and therapeutic approaches. The article first addresses the universal newborn hearing screening that has been implemented in Germany for all infants since January 2009. The process of newborn hearing screening from the maternity ward to confirmation diagnostics is presented in accordance with a decision by the Federal Joint Committee (G-BA). The second topic is pediatric audiology diagnostics. Following confirmation of a permanent early childhood hearing disorder, the search for the cause plays an important role. Hereditary hearing disorders and intrauterine cytomegalovirus (CMV) infection, probably the most common cause of an acquired hearing disorder, are discussed and compared with the most common temporary hearing disorder, otitis media with effusion, which in some cases is severe enough to be relevant for hearing and language development and therefore requires treatment. The third topic covered in this article is speech and language development in the first 3 years of life, which is known today to be crucial for later language development and learning to read and write. There is a short overview and introduction to modern terminology, followed by the abnormalities and diagnostics of early speech and language development. Only some aspects of early hearing and language development are addressed here. Important areas such as the indication for a cochlear implant in the first year of life or because of unilateral deafness are not included due to their complexity. PMID:25587365
