Multi-degree-of-freedom adjustable ankle and knee joint linkage rehabilitative training machine

Abstract

The invention discloses a multi-degree-of-freedom adjustable ankle and knee joint linkage rehabilitative training machine comprising a connecting bracket, a power part, an executive component and fixing devices, wherein the connecting bracket comprises a first base, a second base and a third base, the first and second bases are in hinged connection by virtue of a connecting rod, and the second and third bases are connected with each other by virtue of a gear shaft so as to realize the rotation of the upper base around the gear shaft. The thighs and feet of a treated object can be fixed by virtue of two fixing devices respectively. Finally, the power provided by the power part consisting of two variable frequency motors drives the executive component to realize motion. The multi-degree-of-freedom adjustable ankle and knee joint linkage rehabilitative training machine disclosed by the invention can help the treated object perform plantar flexion and dorsal stretching, inversion and eversion, abduction and endoduction trainings of ankle joints. The movements of dorsiflexion, eversion and abduction can be combined into pronation motion, and the movements of plantar flexion, inversion and endoduction can be combined into supination motion. The multi-degree-of-freedom adjustable ankle and knee joint linkage rehabilitative training machine disclosed by the invention also can realize extension and flexion movements of the knee joints so as to achieve an effect of promoting the rehabilitation of calf muscles and the knee joints.

Description

technical field [0001] The invention relates to a rehabilitation device, in particular to a multi-degree-of-freedom adjustable ankle-knee linkage rehabilitation trainer for people with lower limb movement difficulties caused by diseases, accidental injuries, population aging and the like. Background technique [0002] At present, due to factors such as population aging and diseases, the number of people with difficulty in lower limb movement is constantly expanding. Therefore, the development of effective lower limb rehabilitation training equipment highlights its importance and has a wide range of social and market demands. Most of the existing lower limb rehabilitation training devices are only used for the training of ankle joint movement difficulties, and can only realize dorsiflexion, plantar flexion, varus, valgus, abduction and adduction of the ankle joint. The range and speed of motion on the anatomical plane cannot be adjusted; in addition, the existing devices have...

AI Technical Summary

Problems solved by technology

Most of the existing lower limb rehabilitation training devices are only used for the training of ankle joint movement difficulties, and can only realize dorsiflexion, plantar flexion, varus, valgus, abduction and adduction of the ankle joint. The range and speed of motion on the anatomical plane cannot be adjusted; in addition, the existing devices have not fully considered the joint rehabilitation training of the ankle joint (full degree of freedom), knee joint and calf muscles, which makes it impossible for users to obtain lower limbs in a state close to physiological motion. Rehabilitation training, so there are problems such as poor or unsatisfactory effects to varying degrees
