Description

Hip rehabilitation exercise machine

technical field

The utility model relates to rehabilitation medical equipment, which is a hip joint rehabilitation exercise machine for performing rehabilitation exercise on the hip joint of a human body.

Background technique

The hip joint is the main joint of the human body for walking. There are many patients with hip joint damage, motor function impairment, or even loss of walking function due to disease or trauma. Such patients are often treated by surgery and medical treatment, but after surgery and medical treatment, a stage of rehabilitation training is required, that is, rehabilitation exercises should be used to prevent joint stiffness, muscle atrophy, and adhesions at various tissue levels, and at the same time gradually increase the size of the patient's joints. Mobility, improve and correct the abnormal posture of the patient caused by long-term diseases, and restore the coordination of daily life movements. Therefore, rehabilitation training is a very important treatment content after hip surgery. At present, because there is no corresponding rehabilitation equipment, domestic hospitals usually adopt manual methods. The specific method is: the medical staff of the hospital let the patient lie on the side on the bed, and the medical staff bend over to lift the patient's thigh gently, apply force, and pull the thigh to swing slowly and repeatedly to achieve the effect of moving the hip joint. This kind of rehabilitation training should generally be carried out several times a day. Because such hip joint activities are performed manually, the labor intensity of the medical staff is high, and it is difficult to ensure the proper activity time and frequency of exercise.
