Tracking Systems and Visualization Devices in Virtual, Augmented, and Mixed Reality Games for Motor and Cognitive Rehabilitation and Training: A Scoping Review

Background: Virtual, augmented, and mixed reality (or collectively extended reality, XR) serious games, combined with motion-tracking technologies, are increasingly used for motor and cognitive rehabilitation and training. As XR and tracking technologies advance, a systematic mapping of the related research area could offer relevant insights. Objectives: This review aims to map interactive XR serious games, using motion-tracking technologies for physical or cognitive rehabilitation or training, and describe intervention characteristics and evaluation methods. Eligibility Criteria: Eligible studies were English, peer-reviewed journal articles published between 2015 and October 2025, with more than three participants, using custom XR serious games for rehabilitation or training. Studies were excluded if they focused on technical aspects, passive XR, diagnostic evaluation, psychological therapies, minor participants, procedural training, or education. Charting Methods: Data were charted using a structured form capturing XR characteristics, hardware configurations, study characteristics, and evaluation methods. Results: 61 studies were included. Most employed non-immersive or fully immersive VR interventions, targeting physical upper-body rehabilitation, especially post-stroke and Parkinson’s disease. Usability, acceptability and user experience, and training effectiveness were commonly evaluated with positive outcomes. Conclusions: The findings highlight opportunities for research into augmented and mixed reality approaches, particularly for cognitive function, and use of XR-based interventions across broader populations.
