The Effectiveness of Leap Motion-Based Virtual Reality in the Rehabilitation of Flexor Tendon Injuries of the Hand

This randomized controlled clinical trial aims to evaluate the effectiveness of a Leap Motion-based virtual reality rehabilitation program in patients who underwent surgical repair for flexor tendon injuries of the hand (zones II-V). A total of 66 participants, aged 18-65 years and at least 5 weeks postoperative, will be randomly assigned to two groups: the intervention group will receive routine hand rehabilitation plus Leap Motion-based virtual reality therapy for 20 minutes per day, 5 days per week, for 4 weeks; while the control group will continue routine hand rehabilitation only. Outcomes will include joint range of motion measured with a goniometer, pain intensity assessed with a Visual Analog Scale (VAS), grip strength measured with a Jamar dynamometer, and functional outcomes assessed using the QuickDASH questionnaire. The primary endpoint is the change in range of motion, grip strength, and QuickDASH score from baseline to post-treatment. Secondary endpoints include changes in upper extremity function and pain tolerance. All interventions will be delivered under therapist supervision. This study is expected to provide evidence on whether integrating Leap Motion-based virtual reality into conventional rehabilitation improves clinical outcomes after flexor tendon repair.
