We describe the effects of overground robot-assisted gait training (RAGT) with an untethered exoskeletal wearable robot in two cases of ambulatory older patients with brain disorders. An 80-year-old patient with idiopathic Parkinson’s disease (case 1) was taken through 6 sessions of overground RAGT for 3 weeks. On the other hand, an 84-year old patient with stroke (case 2) received overground RAGT for 6 sessions of overground RAGT for 2 weeks. Each overground RAGT session was conducted for 20 min. Berg balance scale (BBS) in case 1 showed a significant improvement after a 3 weeks intervention, and case 2 showed a significant improvement of Functional Ambulatory Category and BBS after an overground RAGT. In addition, there were no significant side effects in each patient during and after the overground RAGT. We demonstrated the feasibility and safety of overground RAGT with an untethered exoskeletal wearable robot in older patients with brain disorders.
