Motor skill deficits in children with partial hearing

AIM:
We examined the effect of partial hearing, including cochlear implantation, on the development of motor skills in children (aged 6-12y).

METHOD:
Three independent groups of children were selected: a partial hearing group (n=25 [14 males, 11 females]; mean age 8y 8mo, SD 1y 10mo), a nonverbal IQ-matched group (n=27 [15 males, 12 females]; mean age 9y, SD 1y 6mo), and an age-matched group (n=26 [8 males, 18 females]; mean age 8y 8mo, SD 1y 7mo) from three schools with special units for children with partial hearing. All children with partial hearing had a bilateral hearing loss >60 decibels. Motor and balance skills were assessed using the Movement Assessment Battery for Children (MABC) and two protocols from the NeuroCom Balance Master clinical procedures.

RESULTS:
The mean standardized total MABC score of the children with partial hearing (95% confidence interval [CI] 71.8-88.7) was significantly lower than both the age-matched (95% CI 95.8-111.4; p<0.01) and the IQ-matched (95% CI 87.6-103.0; p=0.03) comparison groups. The children with partial hearing had particular difficulties with balance, most notably during tests of intersensory demand. However, subgroup analyses revealed that the effect of cochlear implantation was clearly dependent on the nature of the task.

INTERPRETATION:
Children with partial hearing are at high risk of clinical levels of motor deficit, with balance difficulties providing support for conventional vestibular deficit theory. However, the effect of cochlear implantation suggests that other sensory systems may be involved. A broader ecological perspective, which takes into account factors external to the child, may prove a useful framework for future research.

A comparison of three hearing aid manufacturers' recommended first fit to two generic prescriptive targets with the pediatric population

The purpose of this study is to compare three hearing aid manufacturers' recommended "First Fit" to the generic recommended fittings by DSL i/o and NAL-NL1 for a 12 month old child with varying degrees of sensorineural hearing loss.

Effectiveness of visual feedback provided by an electromagnetic articulograph (EMA) system: training vowel production in individuals with hearing impairment

An electromagnetic articulograph (EMA) system was used to provide a participant with congenital hearing loss visual biofeedback information on speech production. Five normally hearing listeners reported a change in their perception of the speech sound /æ/ in the various conditions of the study.

The role of siblings in the habilitation of families with children who are deaf or hard-of-hearing

Siblings play a vital role in the health of a family as they adjust to having a child who is deaf or hard-of-hearing. In this project, a series of workshops has been designed for the siblings of children with a hearing loss to help better understand hearing loss and foster healthy sibling relationships.

Utilizing hearing assistive technology (HAT) to assess speech recognition: Comparison of word recognition scores obtained by hearing instrument users

The ability for individuals with hearing loss to accurately recognize correct versus incorrect verbal responses during traditional word recognition testing across four different listening conditions was assessed.

Educating deaf and hard of hearing students in the mainstream classroom

This paper examines the mainstreaming of hearing-impaired students in regular education classrooms. It evaluates the areas where teachers need more information regarding deafness, hearing loss and the teaching of hearing-impaired students. The paper also presents a list of resources to assist teachers in the education of hearing-impaired students in the mainstream classroom.

Opportunistic assessment of hearing in elderly inpatients

Objective: To determine the prevalence of occult hearing loss in elderly inpatients, to evaluate feasibility of opportunistic hearing screening and to determine subsequent provision of hearing aids. Materials and methods: Subjects (>65 years) were recruited from five elderly care wards. Hearing loss was detected by a ward-based hearing screen comprising patient-reported assessment of hearing disability and a whisper test. Subjects failing the whisper test or reporting hearing difficulties were offered formal audiological assessment. Results: Screening was performed on 51 patients aged between 70 and 95 years. Of the patients, 21 (41%) reported hearing loss and 16 (31%) failed the whisper test. A total of 37 patients (73%) were referred for audiological assessment with 17 (33%) found to have aidable hearing loss and 11 were fitted with hearing aids (22%). Discussion: This study highlights the high prevalence of occult hearing loss in elderly inpatients. Easy two-step screening can accurately identify patients with undiagnosed deafness resulting in significant proportions receiving hearing aids.

The relation between speech recognition in noise and the speech-evoked brainstem response in normal-hearing and hearing-impaired individuals

Little is known about the way speech in noise is processed along the auditory pathway. The purpose of this study was to evaluate the relation between listening in noise using the R-Space system and the neurophysiologic response of the speech-evoked auditory brainstem when recorded in quiet and noise in adult participants with mild to moderate hearing loss and normal hearing.

Emotion perception and talker discrimination in pediatric hearing aid users

The primary goal of this study is to examine the ability of pediatric hearing-aid listeners, with mild to moderately-severe hearing loss, to perceive emotion and to discriminate talkers. These listeners’ performance is compared to that of similarly-aged listeners with normal hearing and who use cochlear implants.

The communication skills used by deaf children and their hearing peers in a question-and-answer game context

Communication is frequently characterized by a sequence of questions and answers. Little is known about how well students who are deaf or hard of hearing (deaf/HH) understand their hearing classmates in the context of an inclusive setting. This study explored the communication skills used by deaf/HH children when asking and answering questions in a “trivia” game with their hearing peers. Thirty-four children with normal hearing and 34 children with a hearing loss ranging from mild to profound (>90 dB HL) participated in this study. Each of the 34 dyads included 1 child with normal hearing and 1 child with hearing loss, matched by gender and grade level at school. Dyads were videotaped and analyzed. Pairs were compared in terms of their capacity to repeat the question, strategies used to seek information, and accuracy of responses. Results showed that the group of hearing children was able to repeat more questions verbatim compared to the deaf/HH children. The deaf/HH group required a significantly greater number of repetitions, sought a greater number of general clarifications, and correctly answered more questions compared with the group of hearing children. The implications of these findings are discussed in terms of peer communication and pragmatic skill development.

Hearing in athletes with intellectual disabilities : the need for improved ear care

Background The Special Olympics offer the opportunity for athletes with intellectual disabilities to participate in a range of sports at regional, national and international level. A parallel Healthy Athletes programme was introduced to ensure safety at the games but also to collect data on the health needs of those with intellectual disabilities (ID).

Method This study reports on the introduction of a hearing screen for the first time at national games in Great Britain. Given the availability of free local healthcare it was unclear whether the screen would simply duplicate services already accessed locally.

Results Of the 996 athletes who went though the hearing screen 40% were identified with a previously unrecognised hearing loss, 52% required medical ear care and 43% required wax removal. Despite complex competing stimuli within the screening area only 15 of the subjects were unable to complete the full screen. Local clinical services are carried out in more controlled environments therefore it is reasonable to presume that it would be possible for them to provide assessment of ear care and ongoing audiological assessments where needed. It was found that carers and sports coaches were generally unaware of the hearing needs of the athletes, in spite of the fact that they worked so closely with them.

Conclusions The importance of imparting information to carers and coaches, together with the need for access to regular ear care locally is underlined in this study.
