Abstract
Background: Wrist activity is very frequent in our daily routine, and is under heavy load during the movement such as supporting and push-pull. So wrist can get damaged very easily in daily life. Based on the rehabilitation medicine and ergonomics, the particularity and complexity of human limbs should be considered in the design process. During the treatment process, the wrist joint rehabilitation equipment can provide stable, accurate, safe and comfortable repeated rehabilitation training for patients. The use of rehabilitation training equipment can greatly reduce the cost of treatment and improve the rehabilitation efficiency.
Objective: The related patents of rehabilitation training equipment for wrist joint will be reviewed, and the structure and working principle of these equipments will be illustrated. The results of the analysis provide some meaningful reference for the optimal design of the wrist joint.
Methods: Based on the comparative analysis of the latest patents related to wrist rehabilitation equipment, the key problems and future development of the rehabilitation equipment are put forward.
Results: The patents of the rehabilitation training equipment for the wrist are classified in the paper. Studies show that remarkable improvements have been achieved in the invention of the wrist rehabilitation equipment.
Conclusion: In the future, the mechanical design, control system and rehabilitation strategy of wrist rehabilitation equipment should be further studied.
Keywords: Degree of freedom, mechanical structure, rehabilitation equipment, rehabilitation training, working principle, wrist joint.
