Objective To describe the impact of vestibular dysfunction on gross motor development in children with hearing loss. Data Sources MEDLINE (PubMed), Embase (Elsevier), Web of Science (Clarivate), and the Cumulative Index of Nursing and Allied Health Literature (EBSCO). Review Methods A systematic review was reported in concordance with the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses). Articles on children with hearing loss who underwent at least 1 instrumented measure of vestibular function and had gross motor milestones assessed were included. The Downs and Black checklist was used to assess risk of bias and methodological quality. Results Eleven articles were included in the systematic review. Three articles stratified quantitative results of gross motor milestone acquisition by severity of vestibular impairment. Over half of studies were case series published within the last 5 years. This systematic review showed that children with hearing loss and severe, bilateral vestibular dysfunction demonstrate delayed gross motor milestones. However, it was difficult to draw conclusions on whether milder forms of vestibular dysfunction significantly affect gross motor milestone acquisition in children with hearing loss. The reason is that most studies were of low to moderate quality, used different assessment methods, and contained results that were descriptive in nature. Conclusions This emerging area would benefit from future research, such as higher-quality studies to assess vestibular function and gross motor milestones. This would allow for better characterization of the impacts of vestibular impairment, especially milder forms, in children with hearing loss.

Objectives:The objective of this study was to understand the functional impact of vestibular dysfunction on balance control in children with hearing loss. The vestibular system is an important contributor to maintaining balance. In adults, vestibular dysfunction is known to lead to unsteadiness and falls. Considerably less is known about the effects of vestibular dysfunction in children with hearing loss. Design:We conducted a systematic review in concordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. We included articles on children with hearing loss who underwent vestibular and balance testing. The Downs and Black checklist was used to assess the risk of bias.Results: A total of 20 articles were included in this systematic review, of which, 17 reported an association between vestibular dysfunction and balance abnormalities in children with hearing loss. Bias (as measured by the Downs and Black Checklist) was a concern, as most studies were nonblinded cohort studies or case series selected through convenience sampling. Conclusions:Research to date has predominantly found that children with concomitant hearing loss and vestibular impairment tend to perform more poorly on balance measures than either children with hearing loss and normal vestibular function or children with both normal-hearing and normal vestibular function. A standardized approach to assessing both vestibular function and balance would better characterize the impact of vestibular dysfunction in children with hearing loss at the population level.
