Load Dependent Modulation of Spinal Excitability: Linking H-Reflex Supression and Whole Body Vibration Induced Reflex Latency

This study examines how different standing postures and whole-body vibration conditions affect spinal reflex activity. Participants will stand in various positions-with and without vibration of two amplitudes-and H-reflex responses from the soleus muscle will be recorded. Additionally, vibration-induced reflex latency will be assessed across multiple vibration frequencies.
