Acute stroke rehabilitation for gait training with cyborg type robot Hybrid Assistive Limb: A pilot study.

Robot-assisted gait training following acute stroke could allow patients with severe disability to receive a high dosage and intensity of gait training compared with conventional physical therapy (CP). However, given the limited data on gauging the efficacy of Hybrid Assistive Limb (HAL) on gait training in patients with acute stroke, we aimed to evaluate several outcome measures following gait training with HAL. Patients with first-ever stroke, who required a walking aid and were able to start gait training within 1 week of stroke onset were included in the current study. Patients were assigned to either the CP or HAL group. Outcome measures were collected at baseline, and at the 2nd (at 2-6 weeks), and 3rd (at 3-5 months) assessments. All patients underwent physical therapy until the 3rd assessment; patients in the HAL group underwent gait training using HAL until the 2nd assessment. Thirty-seven patients (19 from CP and 18 from HAL, median age = 69 years) completed the study. At the 2nd assessment, the total Functional Independence Measure (FIM) score was higher in the HAL group than in the CP group (90.1 vs. 79.0, p = 0.042). In conclusion, the FIM scale could be used to identify responsiveness to acute stroke rehabilitation using HAL.
