Abstract: BACKGROUND: After an operation, the shoulder and wrist might not be able to lift and swing freely, and must be assisted with rehabilitation training. OBJECTIVE: In this paper, Kinect combined with multiple sensors of a Bluetooth ball is proposed to improve the measurement function of the arm’s micro-motion trajectory, rotation amount, and acceleration, which cannot be detected by Kinect alone. METHODS: We designed two virtual scene rehabilitation games for clinical trials. We performed validity analysis with a paired sample t-test. RESULTS: A significance value of P*< 1 was obtained, and the arm lift angle shows an improvement from 30∘ to 60∘, indicating that the range of motion of the hand and shoulder is gradually improving. CONCLUSION: Experiments show that virtual games combined with multiple sensors can better understand the patient’s rehabilitation situation.
