Summary

This study hypothesize that radius subjecting to mechanical loading may affect excitability of alpha motor neuron innervating muscle, based on its bone mineral density or bone mineral content.

A total of 80 voluntaries are planned to include in this study. Vibration will be applied the right forearm. Muscle electrical activity will be measured on ipsilateral and contralateral flexor carpi radialis (FCR) muscle at rest as EMGrms by surface electromyography (EMG). The rest-EMGrms will be measured at before and during vibration. An increase in muscle electrical activity at rest indicates an increase in motor neuron pool activation. The right distal radius bone mineral content (BMC) and density will be measured by dual energy X-ray absorptiometry (DXA).

The right radius bone mineral density (BMD) and BMC will be evaluated by bone densitometer (GE-LUNAR DPX PRO).

Motor unit potentials will be measured by electromyography at left flexor carpi radialis. Neurotrac ETS device will be used.
