Brief Summary
Objective: This is a randomized controlled trial (RCT) in osteoporosis patients randomized to standard parathyroid hormone (PTH) treatment alone or to standard PTH treatment and Whole-body vibration (WBV). PTH is an effective but expensive anabolic treatment for osteoporosis. WBV stimulates muscles and bones. A combined treatment might have synergistic or additive beneficial effects on bone, reducing fracture risk making treatment more effective and cost-effective. A beneficial effect on muscles and thereby falls risk of WBV may improve fracture risk even further. If the results of this pilot study are promising then a strong case can be made for a large multi-centre RCT using strong endpoints including fractures and falls.
