Background

Rehabilitation exercise equipment is equipment which can help a patient with partial loss of body function to recover body function. Lower limb rehabilitation walker or paraplegic walking brace is used for the patient who loses part or all of the functions of leg to assist the patient to complete walking. The lower limb rehabilitation walker can be used for controlling and guiding the lower limb to move along a given direction, can reduce the bearing force, can help a patient with limited gait after nerve injury, a patient with stroke or a fracture patient accompanied with a rescue gait disorder (such as foot drop) to perform rehabilitation training after the dressing for fixation is removed, helps the patient to stably support the injured limb, can help the patient to move more easily or reduce the pain of the patient, and can enable the wearer to walk for a long time and reduce the fatigue of the wearer. The existing lower limb rehabilitation walker comprises a force application rotary table and an energy storage device, wherein the force application rotary table can be applied to force by the hand of a patient to enable the energy storage device to act so as to provide leg lifting force.
