Research Development of End Traction Shoulder Rehabilitation Device

Background: With the rapid growth of the elderly population, the phenomenon of shoulder subluxation caused by stroke is increasing. For young people, frozen shoulders caused by works and shoulder fractures caused by accidents are also increasing. With the development and popularization of rehabilitation medicine, more and more people realize that rehabilitation and treatment are equally important. Therefore, more and more shoulder rehabilitation devices are designed. Objective: To provide an overview of the end traction shoulder rehabilitation device and introduce their classification, characteristics and development. Methods: This paper reviewed various productions and patents related to the end traction shoulder rehabilitation device. The structural characteristics, differentiations, applications of the end traction rehabilitation device are also introduced. Results: By analyzing the physiological structure and movement characteristics of the shoulder, the rehabilitation mechanism is understood. According to the usage and training track of the end traction shoulder rehabilitation device, it is classified and compared, and the typical characteristics are concluded. The main problems in its development are analyzed and studied. The current and future research of the productions and patents on it are discussed. Conclusion: As a single joint rehabilitation device, the rehabilitation goal of the end traction shoulder rehabilitation device is clearer. Through analysis of existing patents, it is found that the safety, the rehabilitation effect and the rehabilitation program of device need to be further improved. In the future, in order to better serve patients, technologies such as human-machine interaction and rehabilitation process monitoring are also essential.
