An investigation of the effects of various proprioceptive inputs on vestibuloocular reflex and otolith organs.
Background: The vestibular system is crucial for balance and gaze stability. Proprioceptive inputs from the musculoskeletal system significantly contribute to vestibular processing, especially under postural challenge.
Objectives: To examine how proprioceptive inputs in various body positions affect the vestibulo-ocular reflex (VOR) and otolith organ function.
Materials and methods: Thirty healthy adults (18-40 years, no vertiginous symptoms) underwent cervical and ocular vestibular evoked myogenic potentials (c-VEMP, o-VEMP) and video head impulse testing (v-HIT) in four positions: sitting, standing, one-leg standing, and on a balance disk. Primary outcomes included latency, amplitude, and asymmetry for VEMPs; gain and asymmetry for semicircular canals (SCCs) via v-HIT.
Results: c-VEMP latencies and amplitudes did not differ significantly across positions; however, amplitude asymmetry was significantly different between sitting and other conditions (p = .041). o-VEMP results remained consistent (p > .05). v-HIT revealed progressively reduced SCC gain from sitting to disk stance, with significant decreases in lateral SCCs (p < .05) and vertical SCCs (p < .001); asymmetry remained stable.
Conclusions and significance: Increased proprioceptive demand reduced VOR gain and modified c-VEMP asymmetry, reflecting enhanced vestibulospinal engagement. These outcomes likely arise from multisensory interactions rather than proprioceptive input alone, underscoring integrated sensory contributions to postural control.
