Description

A kind of leg flexion and extension exercise device

technical field

The utility model relates to the technical field of rehabilitation exercise, in particular to a leg flexion and extension exercise device.

Background technique

The method of thigh fracture rehabilitation exercise is mainly based on the flexion and extension training and rotation of the affected limb and joints. In the early stage, the passive activity of the affected limb is the main method. The healthy limb can be used to assist the flexion, extension and rotation of the affected limb. After the range of motion reaches a certain level, active activities are the main activities. At this time, after active exercise, a certain amount of muscle strength can be partially restored, and at the same time, joint stiffness and muscle adhesion can be avoided. For femoral fractures, plaster or braces are used for conservative treatment. Knee bending cannot be practiced during the brace fixation period. At this time, only the isometric contraction function exercise of the thigh muscles can be performed. After the plaster or brace fixation is removed, the passive flexion function exercise of the knee joint can be started gradually at this time, and then Then gradually transition to the active flexion function exercise of the knee joint.

At present, when performing passive flexion exercise of the knee joint, medical staff or family members usually need to hold the lower leg of the patient's affected limb to assist the patient to perform leg flexion and extension exercises, and some existing leg flexion and extension exercise devices are often inconvenient for patients to complete knee flexion and extension exercises alone. The passive flexion function of the joint is exercised, and some existing leg flexion and extension exercise devices are inconvenient to fold, and it is not convenient to adjust the leg flexion and extension exercise device according to the length of the patient's legs.
