Conventional and Virtual Reality-Based Neuromuscular Rehabilitation in Scapholunate Instability
Sponsor: Yeditepe University
Summary
Scapholunate instability is a common form of carpal instability that can cause wrist pain, weakness, and functional limitations during daily activities. Conservative rehabilitation approaches are frequently recommended in the early stages; however, there is no standardized rehabilitation protocol, and the effects of different neuromuscular rehabilitation methods have not been sufficiently investigated. The primary aim of this study is to comparatively examine the effects of conventional physiotherapy approaches and virtual reality-supported neuromuscular rehabilitation on forearm muscle activation patterns assessed using surface electromyography, wrist proprioceptive function (joint position sense), pain intensity, and functional improvement in individuals with scapholunate instability, and to identify clinically applicable rehabilitation protocol approaches for this population. In this single-blind randomized controlled trial, participants with pre-dynamic or dynamic scapholunate instability will be randomly assigned to either a conventional rehabilitation group or a virtual reality-supported rehabilitation group. Both groups will receive an 8-week rehabilitation program administered twice per week. Primary outcome measures will include electromyographically assessed forearm muscle activation and wrist proprioception. Secondary outcome measures will include pain intensity, grip strength, wrist muscle strength, and upper extremity functional outcomes assessed using validated clinical instruments. All outcome assessments will be performed before and after the intervention period by an assessor blinded to group allocation.

Interventions
Conventional Physiotherapy Group
Participants assigned to the conventional physiotherapy group will receive a structured neuromuscular rehabilitation program focusing on wrist and forearm stabilization. The intervention will include supervised strengthening exercises targeting scapholunate-friendly muscles, neuromuscular control exercises, and proprioceptive training aimed at improving wrist stability and functional movement patterns. Progressive resistance and task-oriented exercises will be used according to individual tolerance. The rehabilitation program will be administered twice per week for 8 weeks by a licensed physiotherapist.
Virtual Reality-Supported Neuromuscular Rehabilitation
Participants in the virtual reality-supported rehabilitation group will receive the same conventional physiotherapy program as the control group. In addition, this group will participate in virtual reality-based therapeutic exercises delivered through sensor-based interactive games designed for upper extremity rehabilitation. These exercises will aim to enhance wrist and forearm motor control, proprioceptive feedback, and functional task performance by promoting controlled and task-oriented movement patterns. Virtual reality sessions will be supervised by a physiotherapist and integrated into the rehabilitation program with the same frequency and duration as the conventional intervention, administered twice per week over an 8-week period.
