Abstract:

BACKGROUND: The existing artificial rehabilitation training method has low efficiency, and it would take a lot of time, so the therapist cannot focus on the improvement and optimization of treatment.

OBJECTIVE: To design a hand rehabilitation training device for the patient who has hand movement disorder.
METHODS: Based on the analysis of hand movement function, the range of motion of the metacarpophalangeal and interphalangeal joints was obtained, and the hand rehabilitation training device was designed. The device mainly included the exoskeleton executive system and control test system. Finally, the designed device was used for kinematics simulation.
RESULTS AND CONCLUSION: (1) The simulation results showed that the hand rehabilitation training robot’s knuckle range and trajectory had a certain error to human, but the maximum difference was only 5.13 mm. Moreover, the designed adjustment allowance could effectively compensate for the difference. (2) Moreover, each component of the hand rehabilitation training device was controlled by cylinder, and could help patients to complete simple daily life activities. (3) The designed hand rehabilitation training device could help patients to complete simple grasping, holding and kneading. Compared with modern rehabilitation device, the hand rehabilitation training device was simple, lighter weight and wearable. It has good practicability and can be used for hand rehabilitation training.
