Özet
Objectives This study aimed to investigate balance system modifications under different conditions using cervical Vestibular Evoked Myogenic Potentials (c-VEMP) testing. Specifically, we examined vestibular compensation mechanisms in various dynamic balance positions through evoked potential analysis. Methods The study conducted c-VEMP test repetitions on 45 healthy subjects under different conditions. Participants underwent comprehensive otoscopic examination and hearing and balance assessments, with only those demonstrating normal hearing included in the analysis. c-VEMP testing was performed under three distinct conditions: condition 1 (standing on a flat surface with eyes open), condition 2 (standing on a flat surface with eyes closed), and condition 3 (standing on a FoamPad with eyes open). The analysis evaluated P1-N1 latencies and amplitudes in c-VEMP responses, with subsequent statistical analysis of the collected data. Results Analysis revealed statistically significant differences in P1-N1 amplitudes and latencies in left ears when comparing conditions 1 and 2 (p < 0.01). Right ears demonstrated significant differences only in amplitudes between conditions 1 and 2 (p < 0.01). Comparison of conditions 2 and 3 yielded statistically significant differences in P1-N1 amplitudes and latencies for left ears (p < 0.01), while right ears showed significant differences in amplitudes and N1 latency only (p < 0.01). No significant differences were observed in either ear when comparing conditions 1 and 3 (p > 0.05). Conclusion Our findings suggest that while the vestibular system is fundamental, visual input plays a more substantial role in balance maintenance compared to proprioceptive input.
