technical field

The invention relates to a rehabilitation device, in particular to a medical rehabilitation device for leg paralysis.

Background technique

In the hospital, many people are paralyzed in the lower limbs or the whole body due to various reasons. Such patients are in great pain and cannot take care of themselves. If they do not give them regular muscle massage to relax, their muscles will gradually atrophy. Poor blood circulation makes the condition worse. The physical rehabilitation of hemiplegia patients includes functional point stimulation, electronic biofeedback, joint range of motion training, muscle stretching training, muscle strength training, transfer training and gait training. The principle is to gradually increase the patient's muscle strength, inhibit muscle tension, and promote the correct movement pattern of the muscles, but it requires multiple, long-term exercises every day.
