Abstract: With the gradual development of the times, people's material life has been greatly improved. All kinds of sports have become an indispensable part of people's life, but sports are always accompanied by certain risks. People injured by sports show an increasing trend every year. However, it can be found that among many rehabilitation instruments, there is not much research on wrist rehabilitation instruments, which leads to the restoration of bandage splint or plaster fi xation in most of the time. These traditional methods have the problems of slow recovery cycle, diffi cult disassembly and complex replacement. At the same time, most of the wrist rehabilitation instruments that have been developed are large and medium-sized instruments, which can not be carried, can not play a real-time protective role, and can not be well applied to daily life. Based on this, this paper proposes a wearable periodic recovery robot with traditional strap splint, modern transmission and fl exible positioning is proposed.
