Summary

This study aims to investigate how the magnitude of mechanical loading affects reflex latency patterns induced by whole-body vibration (WBV). WBV can trigger two types of reflexes: the tonic vibration reflex (TVR) and the bone myoregulation reflex (BMR), which may be influenced by load-bearing condition. The study will include healthy adult volunteers aged 20-50 years. Reflex responses will be recorded from the soleus muscle using surface EMG during both WBV. Different conditions of mechanical loading (i.e., standing on one foot, both feet) and vibration frequencies (30-36 Hz) will be tested. The main outcome will be the latency of the reflex responses, which will help distinguish between TVR and BMR activation. The goal is to better understand how mechanical load modifies reflex response timing and to characterize the underlying afferent pathways. This knowledge may contribute to optimizing vibration-based rehabilitation strategies.

Interventions

DEVICE

Whole-Body Vibration

Participants will receive whole-body vibration (WBV) at 30-36 Hz under different mechanical loading conditions (e.g., standing on one foot, both feet,). Vibration-induced reflex responses will be recorded from the soleus muscle using surface electromyography. The intervention is designed to evaluate latency differences between tonic vibration reflex (TVR) and bone myoregulation reflex (BMR) under controlled biomechanical scenarios.
