ASSOCIATION BETWEEN THE DEGREE OF SENSORINEURAL HEARING LOSS(SNHL) AND BASELINE BALANCE PERFORMANCE

Abstract

Background: Sensorineural Hearing Loss (SNHL) in children is often associated with vestibular dysfunction, which can affect balance and mobility. Impairment in the vestibular apparatus can lead to deficits in postural control, balance, and coordination, which are essential for normal motor development and daily functional activities. Children with hearing loss may experience delayed motor milestones, reduced spatial orientation, and difficulties in maintaining stability during both static and dynamic tasks.The degree and type of hearing loss may influence postural control and functional performance differently. Understanding this relationship is essential for early identification and targeted rehabilitation.
Purpose: To determine the association between the degree of sensorineural hearing loss and baseline balance performance in children, and to compare balance and mobility between
unilateral and bilateral hearing loss.
Materials & Methods: This cross-sectional correlational study was conducted at Ananda Rangapillai Special School and Shri Patcheappane School for the Hearing Impaired. A total of 85 children aged 7–12 years were recruited using a stratified random sampling method. Data were collected through a single-point assessment including demographic details, audiogram review for hearing severity, Pediatric Balance Scale (PBS), Balance Error Scoring System (BESS), and Timed Up and Go (TUG) test.
Results: Children with unilateral hearing loss demonstrated significantly better functional balance (PBS) but poorer functional mobility (higher TUG scores). No significant difference was observed in static balance (BESS) between unilateral and bilateral hearing loss groups.
Conclusion: The type of hearing loss influences balance performance differently, with bilateral loss affecting functional balance and unilateral loss impacting dynamic mobility. These findings emphasize the need for early identification of at-risk children, comprehensive vestibular assessment, and development of tailored rehabilitation strategies.
