Knee hyperextension limiter for rehabilitation

Abstract

The invention discloses a knee hyperextension limiter for rehabilitation. The limiter is characterized by comprising a fixed base I, a fixed base II and an angle limiting strip for connecting the fixed base I and the fixed base II, wherein connecting belts I are arranged at two sides of the fixed base I, connecting belts II are arranged at two sides of the fixed base II, a sliding way is arrangedon the surface of each connecting belt I in the width direction of the connecting belt I, a sliding block moving along the corresponding sliding way is arranged in the sliding way in a matched mode, one end of the angle limiting strip is connected to the corresponding sliding block, and the other end of the angle limiting strip is connected to the outer surface of the fixed base II through a fixing buckle. The limiter is simple and stable in structure, low in cost and convenient to wear; and by means of an angle limiting strip block fixed to the rear side of the knee joint, when a patient walks, after the knee joint extends by a certain angle, the further extension of the knee joint is limited, so that excessive extension or reverse extension of the knee is prevented.

Description

technical field [0001] The invention relates to the field of rehabilitation devices, in particular to a knee hyperextension limiter for rehabilitation. Background technique [0002] Knee joint hyperextension is also called knee opisthotonus. In the process of walking and standing, the knee joint of the lower limb of the affected side is hyperextended during the support period, the center of gravity of the body moves backward, the hip joint of the affected side is excessively flexed, and the body tends to lean backward. Long-term hyperextension of the knee joint can significantly increase the incidence of bone and joint degeneration, cause excessive wear of the knee joint, cause joint deformity, and significantly increase the incidence of bone and joint degeneration. In the rehabilitation training device, there is no Rehabilitation device for hyperextended knees caused by conditions such as stroke or spinal cord injury. Contents of the invention [0003] In order to solve ...
