Study summary

This pilot study is designed to analyze the effects of Vibration Therapy (VT) on grip strength and level of forearm contraction by measuring hand grip dynamometry and surface Electromyography (sEMG) using the BioPac sEMG and digital dynamometry devices after the application of both passive and active Vibrational Therapy (VT) using the PowerPlate.
