Digital monitoring of motor function in Parkinson’s disease using Markerless motion analysis and exergaming

Introduction: Motor impairment in Parkinson's disease (PD) significantly compromises functional independence. While continuous rehabilitation is crucial, traditional models face logistical and economic barriers that limit continuity of treatments. Methods: To address this challenge, we developed a novel exergaming platform leveraging Google MediaPipe for markerless, real-time kinematic tracking via a standard webcam, eliminating the need for specialized hardware and delivering engaging, gamified physical exercises designed for domestic settings. This study investigates the feasibility, usability, and preliminary clinical impact of a 10-session gaming protocol in 14 out-of-hospital patients. Results: = -0.66) scores. Furthermore, the system detected performance incongruence related to medication timing and motor fluctuations. In addition, a session-by-session analysis revealed consistently high patient satisfaction, engagement, and system usability scores, alongside low perceived physical fatigue. Discussion: These findings underscore the clinical validity and high acceptance of the proposed solution as a training and remote monitoring tool. By providing granular, longitudinal data, this highly accessible solution offers a promising approach to personalized home-based functional training for people with PD.
