The present invention relates to a knee joint rehabilitation exercise device, and more particularly to the elderly, disabled or fracture patients with weakened walking ability to operate the knee joint rehabilitation exercise by rehabilitation exercise without the help of others to recover the knee joint It is about.

In general, people who have poor walking ability due to weakened unit strength or surgery cannot move for a long time, and thus, joints and unit strength required for walking are weakened and hardened. In particular, fracture patients should not give a sudden movement to the joints and the entire skeleton after loosening the cast or fixation because they remain in a cast for a long time or remain stationary for fixation.

Therefore, the elderly who have lost their walking activity due to aging weakened, and those whose walking ability has weakened due to weakened unit muscle strength need exercise that can continuously increase the unit muscle strength, and they try bone union due to fracture and do not move for a long time. Patients who do not have to gradually move their joints should be able to walk without difficulty.

The walking ability can be improved when the hip, knee and ankle joints are smoothly exercised. Each joint is surrounded by a soft medullary joint membrane, muscles and tendons, so that the rehabilitation apparatus for improving walking ability is It is required to give an element an effective exercise.

Therefore, a patient rehabilitation bed including a device capable of moving muscles in a patient bed is used. However, the patient rehabilitation bed is configured to move the muscle inside the bed, the movement range of the device that can move the muscles is small, only the effect of temporarily preventing joint hardening or contraction of the muscles Since the muscles cannot be moved to the extent that the rehabilitation effect can be exerted, even if the rehabilitation bed is used, there is a problem that rehabilitation treatment by a caregiver or a rehabilitation therapist must be performed for the rehabilitation of the patient.
