Abstract
Rehabilitation is critical for restoring mobility and strength post-injury or surgery. However, the repetitive and tedious nature of traditional therapies often leads to poor adherence and sub-optimal outcomes. In particular, patients post-knee arthroplasty surgery do not consistently experience relief from chronic pain or restoration of proprioceptive sense. This project explores the integration of haptic feedback in a virtual reality rehabilitation game for knee extension training, aiming to increase engagement, enhance motor learning, and potentially aid in chronic pain treatment. After evaluating various haptic systems, a knee sleeve equipped with vibration motors was developed and tested for its ability to provide tactile stimulation in game. Preliminary EMG analysis indicated no adverse effects on muscle activation. A 3-day control study with healthy participants showed that the vibration motors offered a consistent, perceivable sensation around the knee. Initial data from five participants revealed significant improvement in both groups after training with the device, suggesting motor learning due to the game. Furthermore, a significant difference in the test group’s performance over the control group suggests the potential of haptic feedback to improve rehabilitation outcomes. Continuation of the study with a larger sample size and further research in patient populations is recommended to confirm these findings and explore broader applications.
