Active rehabilitation programs were done for all patients. Participants were asked to attend exercise program at PT room or bedside. Exercise program was offered once or twice daily on weekdays, by trained kinesiologists. In PT programs, most patients performed strengthening exercise of lower extremities, balance training, sit-up training, sit-to-stand training and gait training for about 30 minutes. Each program was individualized to participants' current physical function. In bedside programs, patients also underwent strengthening exercise and balance training without gait training for about 10 minutes. The duration of exercise program at PT room depends on the patient's condition(upto 1 month).
