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

The wearable vibration device aims to consistently deliver vibrations directly to the hip and spine and allowing use during many everyday activities. We propose that demonstrating higher rates of compliance and consistent delivery of optimal force, with accelerometer feedback, will provide a superior alternative to whole body vibration and is plausibly more effective at preventing bone loss in postmenopausal women than vibration platforms in the home setting.

About this study

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 30 minute treatment with the WVD.

  • Medical Implants (excluding dental implants).
  • Diagnosed with Paget's disease, heart disease, uncontrolled hypertension, renal disease, chronic fatigue syndrome, herniated disc, severe peripheral neuropathy, severe osteoarthritis.
  • Any bleeding disorder or treatment with a blood thinning medication within the last 2 years.

Treatment and study plan

Wearable vibration belt

Device

The device is worn, a wearable vibration belt, for a specified time. This will provide vibration starting at the hips.

Sham, wearing belt

Device

The device is worn, for a specified time. It will not be turned on during this period. It is only sham.

Primary outcomes

  1. Percent Change in Blood-based Biomarker of Bone Loss

    Time frame: Baseline and 30 minutes after completing the 30-minute treatment session

    Percent change in NTX, a biomarker of bone loss activity measured in the blood. Percent change in NTX was determined from Baseline (pre-treatment) to 30-minutes post-treatment for the sham treatment and the active treatments. The difference in percent change was then compared between active and sham treatments.
