Description

A gait rehabilitation device capable of adjusting training resistance

technical field

The utility model relates to the field of rehabilitation and health care, in particular to a gait rehabilitation device capable of adjusting training resistance.

Background technique

Hemiplegic gait, also called circle gait, is a common walking posture of hemiplegic patients. It is characterized by the fact that the limbs on the affected side can walk, but when walking, the upper limbs are often bent and the lower limbs are straightened. The hemiplegic lower limbs take a step and draw a circle In a semicircle, throw it to the front of the body, then move the center of gravity to the affected side, and then step on the healthy side. This special walking method is clinically called hemiplegic gait. During the whole process, the body is in a state of lateral bending and twisting. The main reason for the formation of this gait is that the strength of the affected side of hemiplegia is poor. When walking, the foot turns inward, and the heel cannot fully touch the ground. The hip joint drives the lower limbs to move forward.

The prognosis of patients with hemiplegia requires targeted exercise to help improve the gait of the hemiplegia, so that the patient can gradually enhance the strength and control ability of the affected side of the hemiplegia, and improve the patient's mobility and quality of life in the later period. Hemiplegic patients need different targeted training during different recovery periods. For example, in the early stage of recovery, the strength and control of the affected side of the patient are weak, and an external power source is needed to drive the patient to perform gait training; while in the middle and late stages of recovery, the strength of the affected side is strengthened, and different degrees of resistance are required to improve the training effect. train.

In the prior art, there are rehabilitation devices for hemiplegic gait, but they cannot adjust the training resistance.
