Facilitating Self-Monitored Rehabilitation With Biofeedback and Virtual Reality

Rehabilitation is a crucial part of recovery after total knee arthroplasty (TKA) which remains the most effective treatment for end-stage arthropathy. Studies have shown that if performed in a quality manner, repetitive and sufficient motor-centered rehabilitation could improve post-surgery motor abilities as well as health-related quality of life. Yet in China, post-surgery clinical or at-home rehabilitation is seldomly provided due to the limited hospital resources and the lack of appropriate supervision during at-home rehabilitation. We thus propose a VR-based and biofeedback supplemented closed-loop self-monitoring rehabilitation system to facilitate unsupervised therapeutically appropriate rehabilitation. We propose a rehabilitation system based on collaborative design with the therapists and characterize the system based on iterative prototypes and evaluation. The system is then evaluated through in-the-wild test sessions with the patients.
