Background:
Information about the role of auditory input and motor control is limited.
Objectives:
Assessment the relationship between auditory and vestibular information with specific motor and cognitive functions.
Methods:
Posturography in 17 Pre-lingual Cochlear Implant Adolescents, (PCIA) age 14.06 ± 3.05 in four sensory conditions was analyzed: (A) eyes open, cochlear implant (CI) on, (B) eyes open, CI off, (C) eyes closed standing on a foam over a platform (ECFP) with CI on, and (D) ECFP, CI off. Gait velocity (GV) was registered by inertial sensors using a 10-meter test. Vestibulo-ocular reflex (VOR) was evaluated with the video head impulse test (VHIT) and visual spatial skill (VS) assessed with the WISC-V test.
Results:
SV had no significant difference between conditions A and B (p = .2461). Comparing C and D, SV values decreased when CI was turned on (p = .0036). A significant linear relationship between VOR and GV (p = .0064) generating the VOR gain loss lower gait. Relationship between VOR and VS scores was no significant (p = .685).
Conclusions And Significance:
Auditory information is a relevant cue when somatosensory and visual inputs are modified and range of vestibular function influence in a dynamic motor activity as gait, facts which must be considered in the neurodevelopment control.
