The goal of this clinical trial is to learn if a gamified virtual reality (VR) rehabilitation program can effectively reduce pain, improve functionality, and enhance balance in adults aged 40-64 years diagnosed with knee osteoarthritis. The main questions it aims to answer are:
Can the VR rehabilitation program reduce pain and disability compared to conventional physical therapy alone? Can the VR rehabilitation program improve balance and functionality in patients with knee osteoarthritis? Researchers will compare a group receiving the VR-based rehabilitation program alongside conventional therapy to a group receiving only conventional therapy to see if the addition of VR leads to superior outcomes.
Participants will:
Undergo either VR-based rehabilitation combined with conventional therapy or conventional therapy alone.
Complete assessments at three time points (baseline, 3 weeks, and 7 weeks) using measures such as pain scales, disability indices, and balance tests.
