The aim of the present study is to investigate the effects of vibrating the forearm bone in the free limb on muscle strength and bone mineral density of the forearm in patients with forearm/elbow fracture.

A total of 80 patients with forearm/elbow fracture are planned to include in this study. Patients will be randomly attained Training or Control group. Training period will be six weeks. Patients in the control group will receive standard care for provided for fractures, including fixation and rest.Before the start of the study and after six weeks, bilateral bone density of distal radius will be measured by DXA. Before trials, grip strength and the rest muscle electrical activity of contralateral wrist flexors and extensors will be measured. After six weeks, bilateral grip strength and the rest muscle electrical activity will be measured.
