Development of a Digital Rehab Program With Gamification
Sponsor: Tan Tock Seng Hospital
Summary
Total knee arthroplasty is commonly followed by a period of postoperative rehabilitation to restore knee movement, lower-limb strength, and physical function. This randomized study evaluated KIMIA Recover, a wearable sensor-supported home rehabilitation system, in patients undergoing first-time unilateral total knee arthroplasty. Participants were randomly allocated to KIMIA Recover-supported rehabilitation or conventional postoperative rehabilitation and followed for 12 weeks after surgery. KIMIA Recover comprises a wearable knee motion sensor, a patient mobile application providing guided rehabilitation exercises and feedback, and a clinician dashboard that enables review of rehabilitation progress. Outcomes included knee range of motion, 30-second sit-to-stand performance, health-related quality of life, healthcare resource use and costs, quadriceps strength, straight-leg-raise ability, walking-device use, Oxford Knee Score, and postoperative complications. The randomized phase was originally designed to recruit a larger cohort but enrolled 21 participants. Because recruitment and follow-up were limited, the completed study is being reported as a pilot and feasibility evaluation, with clinical between-group comparisons considered exploratory. This ClinicalTrials.gov record is being registered retrospectively after completion of participant recruitment and follow-up.

KIMIA Recover
KIMIA Recover is a wearable sensor-supported postoperative rehabilitation system comprising a knee motion sensor, patient mobile application, and clinician dashboard. The application provides rehabilitation education, guided exercises, visual and audio cues, feedback, reminders, and progress tracking. The clinician dashboard enables healthcare professionals to review rehabilitation progress and exercise participation. Participants were instructed to wear the sensor for 12-16 hours per day during the inpatient period and for 8-12 hours per day during active and exercise periods after discharge, for up to 12 weeks
Conventional Postoperative Rehabilitation
Participants performed prescribed home rehabilitation exercises without wearable or application-based monitoring. Outpatient physiotherapy was provided according to clinical need, including assessment of recovery, exercise instruction, feedback, and progression of exercises.
