Early CPM rehabilitation training can greatly reduce the possibility of disability. The rehabilitation training method can improve the motor function of the patient to a certain extent, but requires a large amount of labor, is expensive, the rehabilitation treatment is not standardized, and the effect is difficult to quantitatively evaluate. The robot-assisted rehabilitation therapy can well solve the above defects and has increasingly become a research direction of modern rehabilitation medicine and medical engineering. The exoskeleton rehabilitation equipment is a technology combining rehabilitation medicine and related robot technology, and provides an auxiliary device for restoring the normal shape or function of a limb or organ of a patient after injury or illness. It enables clinicians to rely on a new treatment mode, so that more patients have the opportunity to receive hand rehabilitation treatment after stroke or injury.
