Due to braking, pain, and psychological factors after severe hand injuries, based on the theory of “central nervous system-peripheral loop”, hand injuries can affect the functional connections of the brain, thereby affecting the rehabilitation process. Therefore, guiding patients to actively participate in task-oriented functional training in a safe manner and promoting their safe return to work is a challenge faced by current occupational rehabilitation work. A virtual reality occupational rehabilitation system developed based on VR technology conducts rehabilitation training for patients in both real and virtual scenarios. This system is developed in cooperation with HTC-VIVE-Pro devices and some actual devices. We designed some experiments to evaluate the feasibility of this system, and the results show that it does indeed contribute to patient rehabilitation.
