Both hands are supported by the armrest 19, which makes it more convenient to apply force, and the patient's sitting training is more stable. The extrusion spring 5 is slowly compressed, and the movable cylinder 6 slides downward along the surface of the fixed cylinder 4. The extrusion spring 5 has a rebound effect on the patient's stepping force, thereby exercising the patient's lower limbs. The degree of stepping and pressing is determined according to the patient's rehabilitation training needs. The patient actively determines the downward force, and the training rehabilitation method is safer and will not cause damage to the patient's legs.
