NCT01908439

Brief Summary

The purpose of this study was to examine the validity of the measurement method based on observation of vibration stimulation-MUAP (motor unit action potential) (1 to 1) matching that helps to measure human WBV-induced muscular reflex latency and to compare these results with the latency determination obtained using the classical methods. The investigators' principle hypothesis is that the simple method is capable of determining the WBV induced reflex response latency as reliably as the complex methods described earlier. To achieve this goal, the investigators have averaged the electrical responses of the soleus muscle (sEMG and multi motor unit (MMU) potential) against the vertical force data obtained during all the six vibration frequencies tested in this study. The investigators have then combined all the averaged EMG data belonging to six different vibration frequencies to generate the 'cumulative averaged' sEMG and MMU for each subject. The investigators have also obtained the standard error for the cumulative averaged records which indicated the WBV-induced muscular reflex (WBV-IMR) latency.
