The ability to walk up and down the stairs at three months of hemiplegia mainly depends on the recovery of the patient’s motor function. Going up and down stairs is part of daily living ability, which is one of the important rehabilitation training for hemiplegic patients. Up and down stairs training can not only exercise the muscle strength of the lower limbs, but also promote the patient’s independent self-care ability. Walking up and down stairs requires patients to have certain lower limb muscle strength, joint stability, standing balance and walking ability. It is recommended that hemiplegic patients should be assessed by a professional rehabilitation doctor or therapist before going up and down the stairs, and then go up and down the stairs under professional guidance. It is not advisable to practice up and down stairs blindly, as this may cause pain and solidification of incorrect movement patterns, and other adverse consequences.
