Description

A lower limb exercise device for clinical rehabilitation

Technical Field

The utility model relates to the technical field of lower limb exercise devices, in particular to a lower limb exercise device used in clinical rehabilitation.

Background Art

During surgical operations, patients with fractures often need to use plaster or other auxiliary fixation devices to fix the affected area, and then rest. They cannot move easily during the resting process, especially patients with lower limb fractures. Since the legs cannot be exercised for a long time, they are prone to sequelae such as lower limb stiffness and inflexible extension, which can lead to muscle atrophy and affect future mobility. Therefore, in the early postoperative period, patients need to practice joint mobility to prevent postoperative complications, improve the range of motion of the knee joint, and restore walking ability, so that the final therapeutic effect of the operation can be better.

The existing patent (Announcement No.: CN214971504U) discloses a leg rehabilitation training device, which includes a pulley bar, a platform for placing the soles of the feet, and a plurality of pulleys, wherein the pulley bar is fixedly arranged below the platform, and the plurality of pulleys are rotatably connected to the pulley bar. However, when the device is used, the patient needs to be transferred from the bed to the device for training. For patients who have been bedridden for a long time and have difficulty in moving, the transfer may easily lead to recurrence of wounds and cause secondary injuries.
