Association between vestibular function and motor performance in hearing-impaired children

Area of Science:

• Pediatric Audiology
• Vestibular System Function
• Motor Development

Background:

• Hearing impairment (HI) can impact a child's overall development.
• Vestibular dysfunction is common in some HI children and may affect motor skills.

Purpose of the Study:

• To compare the clinical balance performance of normal-hearing (NH) children with that of hearing-impaired (HI) children.
• To investigate the association between vestibular function and motor performance in children.

Main Methods:

• Prospective study involving 36 children (ages 3-12) divided into three groups: NH with normal vestibular function, HI with normal vestibular function, and HI with abnormal vestibular function.
• Utilized vestibular evoked myogenic potential testing and clinical balance assessments (balance beam walking, one-leg hopping, one-leg stance).

Main Results:

• HI children with abnormal vestibular function demonstrated significantly lower motor performance across all balance tests compared to NH children.
• HI children with normal vestibular function also showed significantly poorer balance performance than NH children on specific tasks.

Conclusions:

• Vestibular function is associated with motor performance in hearing-impaired children.
• Motor deterioration is more pronounced in HI children when vestibular impairment is present alongside auditory dysfunction.
