Prostheses play an important role in the life of the amputee.On the one hand,it can provide support for the human body to stand,and on the other hand,it can help the amputee's residual limb movement.A magnetorheological prosthesis is a new type of semi-active prosthesis that uses a magnetorheological damper as the damping device.This article introduces the structure and working principle of magnetorheological prostheses in detail;points out the characteristics and applications of magnetorheological prostheses,and classifies and compares magnetorheological prostheses with different structural characteristics.At the same time,it explains the current magnetorheological prostheses.The mainstream control methods in the prosthetic knee joints are compared and analyzed according to the characteristics of different control methods.Finally,the future development trend and practical application of prostheses have prospected.
