Effectiveness of Exercise Relative Motion Orthoses for Limited Finger Joint Motion

This randomized controlled trial investigates the effectiveness of two exercise orthosis designs-the Relative Motion Flexion (RMF) and Relative Motion Extension (RME) orthoses-for improving motion in patients with proximal interphalangeal joint (PIPJ) flexion or extension deficits. A total of 148 adult patients with acute hand injuries and a minimum 10° difference between active and passive PIP joint motion will be enrolled. Participants are stratified by their primary motion deficit and randomized to either the exercise orthosis or placebo orthosis group. The orthosis is worn for 4 weeks, with follow-up assessments at weeks 6 and 8 to evaluate range of motion and patient satisfaction. All participants will continue standard hand therapy throughout the study.
