Wearable Vibration Device to Prevent Bone Loss in Postmenopausal Women--Aim 2

The goal of this study is to demonstrate that postmenopausal women will tolerate our device,
have high rates of compliance with the study protocol, receive consistently therapeutic
levels of vibration and see significant effects on bone turnover based on plasma markers of
bone anabolism and catabolism.

The anticipated outcomes from serum draws are an improvement in two bone turnover markers
after a 9-30 minute treatment with the WVD.
