In recent years, with widespread access to virtual reality (VR) headsets, VR has become an affordable supplement to physiotherapy. Researchers explore the use of existing commercial games or develop new ones to enhance physiotherapy sessions, finding that gamers exhibit reduced nervousness, report less pain, and experience increased enjoyment. However, ensuring consistent exercise adherence poses a challenge. Another area of interest involves integrating robots to aid patients. In our study, we seamlessly integrated a Kuka LBR Med 7 R800 with Unity through a meticulously developed Application Programming Interface (API). This fusion of robotics and video games assists in physiotherapeutic exercises. The games were developed specifically for compatibility with the Oculus Quest 2 virtual reality headset, chosen as the preferred VR platform for this study. Two games, using common game-design concepts with distinct approaches, were evaluated for system acceptance via the Technology Acceptance Model (TAM) and usability through the System Usability Scale (SUS). In a well-distributed group of 15 participants with an average age of 22 years, greater technology acceptance was observed among women. Those playing more hours per day reported lower perceived ease of use, though one game achieved an excellent SUS rating of 83.3. Conversely, the other game, which was tested with 11 participants with an average age of 20 years, showed a potential negative impact on behavioral intention. The particular sample used in the study has limitations, so the study should be repeated to obtain more reliable and conclusive results. In conclusion, the successful integration of VR and robot assistance in physiotherapy games relies on the proper application of the game design principle.

Upper and lower limb rehabilitation training is essential for restoring patients’ physical movement ability and enhancing muscle strength and coordination. However, traditional rehabilitation training methods have limitations, such as high costs, low patient participation, and lack of real-time feedback. The purpose of this study is to design and implement a rehabilitation training evaluation system based on virtual reality to improve the quality of patients’ rehabilitation training. This paper proposes an upper and lower limb rehabilitation training evaluation system based on virtual reality technology, aiming to solve the problems existing in traditional rehabilitation training. The system provides patients with an immersive and interactive rehabilitation training environment through virtual reality technology, aiming to improve patients’ participation and rehabilitation effects. This study used Kinect 2.0 and Leap Motion sensors to capture patients’ motion data and transmit them to virtual training scenes. The system designed multiple virtual scenes specifically for different upper and lower limbs, with a focus on hand function training. Through these scenes, patients can perform various movement training, and the system will provide real-time feedback based on the accuracy of the patient’s movements. The experimental results show that patients using the system show higher participation and better rehabilitation training effects. Compared with patients receiving traditional rehabilitation training, patients using the virtual reality system have significantly improved movement accuracy and training participation. The virtual reality rehabilitation training evaluation system developed in this study improves the quality of patients’ rehabilitation and provides personalized treatment information to medical personnel through data collection and analysis, promoting the systematization and personalization of rehabilitation training. This system is innovative and has broad application potential in the field of rehabilitation medicine.
