[0002] In the field of medical rehabilitation, lower limb motor dysfunction caused by brain injury brings great pain and inconvenience to patients. Currently, during the rehabilitation treatment of lower limb motor dysfunction caused by brain injury, patients are required to sit in a seat and have their lower limbs lifted by medical staff to perform flexion and extension rehabilitation exercises.
