Review of Research on Knee-postoperative Rehabilitation Training Robot

Abstract

Knee-postoperative rehabilitation training robot (rehabilitation training robot in short) is developed to assists patients who undergoing knee surgery for rehabilitation training, help them recover knee-joint's function and reduce the workload of rehabilitation physiotherapists and families, which is widely used in rehabilitation training after knee surgery. The movement characteristics of knee joint and rehabilitation needs after operation are first summarized, and then the rehabilitation training robots are classified into three types (i.e., end-effector, exoskeleton, and other types). The design concept, structural characteristics, control strategies of rehabilitation training robot, and rating system of rehabilitation training effect are also addressed in detail. The existing problems, key technologies, and development trend of the knee rehabilitation training robot are concluded and discussed.
