Effect of Whole Body Vibration on Rehabilitation in Distal Radius Fractures

This study is a randomized controlled clinical trial designed to evaluate the effects of whole body vibration (WBV) added to conventional rehabilitation on functional and sensorimotor recovery in patients with conservatively treated distal radius fractures. Following immobilization, patients often experience pain, reduced range of motion, decreased muscle strength, and impaired proprioception, which negatively affect functional recovery. WBV is thought to enhance neuromuscular activation and improve proprioceptive input, thereby contributing to functional performance. Participants will be randomly assigned into two groups; the experimental group will receive WBV in addition to conventional rehabilitation three times per week for eight weeks, while the control group will receive only conventional rehabilitation. Assessments will be conducted at baseline, week 4, and week 8. The primary outcome measure is the Patient-Rated Wrist Evaluation (PRWE), while secondary outcomes include QuickDASH, Numeric Pain Rating Scale (NPRS), joint position sense, grip strength, range of motion, and fine motor skills.

Inclusion Criteria: * Adults aged 18 to 65 years. * Unilateral distal radius fracture treated conservatively with cast or splint. * Completion of the immobilization period with radiologically confirmed stable callus formation. * Referred for physiotherapy after conservative treatment. * Able to understand study procedures and provide written informed consent. * Initiation of rehabilitation within 72 hours after cast removal. Exclusion Criteria: * Previous surgery or severe trauma to the affected upper extremity. * Open wound or active infection at the fracture site. * Peripheral neuropathy or severe neurological disorders. * Vestibular disorders or conditions contraindicating whole-body vibration therapy. * Pregnancy. * Severe osteoporosis. * Active inflammatory or vascular disease affecting the upper extremity. * Cognitive impairment preventing participation in the study. * Inability to attend the rehabilitation program regularly.
