Rehabilitation refers to treatments and activities aimed at restoring motor functions and abilities, such as basic movements, walking, and activities of daily lives, following a physical disability. In this study, we propose a rehabilitation support system that uses mixed reality technology. The system allows users to choose from upper body, lower body, or whole body rehabilitation programs. By incorporating gamification, the system increases patient motivation and helps them continue exercise. Moreover, we evaluated the operability, visibility, functionality, relevance, effectiveness, and applicability of the system. The results show that the proposed system performs well in all categories.
