Design of Upper Limb Rehabilitation Assistance Training System Based on Unity 3D

Cerebral stroke is a disease with a high incidence and disability rate. As its most common sequela, upper limb motor dysfunction seriously affects patients' daily activities when it occurs. Traditional rehabilitation training requires patients to go to medical institutions, which is limited due to the lack of human resources. In recent years, the development of virtual reality has provided a novel technology for rehabilitation training, which has attracted more attention in the medical field. In order to overcome the limitations of traditional rehabilitation approaches, this paper develop a virtual reality upper limb rehabilitation training assistance system based on wearable devices and Unity 3D engine. This system combines monotonous training movements in rehabilitation training with virtual games, achieving interaction between human arms and virtual training scenes. The system consists of two upper body training games. It has entertainment, sustainability and real-time feedback functions, providing users with an immersive gaming experience and meeting their training demands for different parts of the upper limbs.
