Description

Handrail lifting structure for lower limb muscle strength training

Technical Field

The utility model relates to a low limbs flesh power trainer technical field, concretely relates to handrail structure that rises and falls for low limbs flesh power training.

Background

The muscle strength is the maximum strength generated when the muscle or muscle group contracts, and the muscle strength is classified into six grades, namely 0-5 grades, wherein 5 grades are normal. Low muscle strength means that the muscle relaxes in the absence of distended muscle belly and normal toughness as the resistance encountered by the active body is reduced. Low muscle strength presents different clinical responses with the patient.

The low muscle strength of the lower limbs is mainly expressed by the following conditions: firstly, the user cannot walk normally; secondly, the lower limb reaction force is slow; thirdly, the legs are soft, and the leg bending and stretching movement which cannot be normally turned over and cannot be normal can occur; and fourthly, the muscle function of the legs is declined and is not controlled by cerebellum.

Under many conditions, when the lower limb muscle strength is low, the rehabilitation can be carried out through later-stage rehabilitation training; at present, there are a variety of rehabilitation devices for lower limb muscle training. The existing lower limb muscle strength training equipment comprises standing type training equipment and sitting type training equipment, and when a patient can stand, the standing type training equipment is usually adopted; when the patient is unable to stand, a sitting exercise device is often used. However, it is difficult to adjust the training intensity of the lower limb muscle strength of the patient in accordance with the recovery of the lower limb muscle strength of the patient in both the standing training apparatus and the sitting training apparatus.
