Abstract

Objective: To examine the efficacy of postural strategy training using a personal transport assistance robot (PTAR) for patients with central nervous system disorders. Design: Single-group intervention trial. Setting: Rehabilitation center at a university hospital. Participants: Outpatients (N=8; 5 men, 3 women; mean age, 50±13y) with a gait disturbance (mean time after onset, 34±29mo) as a result of central nervous system disorders were selected from a volunteer sample. Interventions: Two methods of balance exercise using a PTAR were devised: exercise against perturbation and exercise moving the center of gravity. The exercises were performed twice a week for 4 weeks. Main Outcome Measures: Preferred and tandem gait speeds, Functional Reach Test, functional base of support, center of pressure (COP), muscle strength of lower extremities, and grip strength were assessed before and after the completion of the exercise program. After the exercise program, enjoyment of exercise was investigated via a visual analog scale questionnaire. Results: After the program, statistically significant improvements were noted for tandem gait speeds (P=.009), Functional Reach Test (P=.003), functional base of support (P=.014), and lower extremity muscle strength (P
