Flexor Tendon Injuries of the Hand (Zones II-V)
Conditions
Brief summary
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.
Interventions
DEVICELeap Motion-based Virtual Reality Therapy
Arm 1 - Experimental (Leap Motion + Routine Hand Rehabilitation) Intervention Description: Participants will receive standard postoperative hand rehabilitation plus Leap Motion-based virtual reality training. The VR training will be performed for 20 minutes per day, 5 days per week, for 4 weeks, in addition to routine rehabilitation. The Leap Motion Controller tracks hand and finger movements without physical contact and allows participants to practice functional tasks and grasp patterns in a virtual environment. Arm 2 - Active Comparator (Routine Hand Rehabilitation Only) Intervention Description: Participants will receive only routine postoperative hand rehabilitation, performed for 1 hour per day, 5 days per week, for 4 weeks, supervised by a therapist.
OTHERActive Comparator - Routine Rehabilitation Only
Participants will receive only routine postoperative hand rehabilitation, performed for 1 hour per day, 5 days per week, for 4 weeks, supervised by a therapist.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Upper limb disability/function | Baseline and 4 weeks post-treatment | Functional disability of the upper limb assessed with the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire. In the Q-DASH, a higher score indicates worse outcome, while a lower score indicates better outcome. |
| Joint range of motion (ROM) | Baseline and 4 weeks post-treatment | Assessed with a manual goniometer. Comparison between baseline and after 4 weeks of treatment. A higher ROM indicates a better clinical condition. |
| Grip strength | Baseline and 4 weeks post-treatment | Assessed using a Jamar hand dynamometer. |
