Effects of robot-(Morning Walk®) assisted gait training for patients after stroke: a randomized controlled trial
To investigate the effects of Morning Walk®–assisted gait training for patients with stroke.
Design:Prospective randomized controlled trial.
Setting:Three hospital rehabilitation departments (two tertiary and one secondary).
Patients:We enrolled 58 patients with hemiparesis following a first-time stroke within the preceding year and with Functional Ambulation Category scores ⩾2.
Intervention:The patients were randomly assigned to one of two treatment groups: 30 minutes of training with Morning Walk®, a lower limb rehabilitation robot, plus 1 hour of conventional physiotherapy (Morning Walk® group; n = 28); or 1.5 hour of conventional physiotherapy (control group; n = 30). All received treatment five times per week for three weeks.
Main outcome measurements:The primary outcomes were walking ability, assessed using the Functional Ambulation Category scale, and lower limb function, assessed using the Motricity Index-Lower. Secondary outcomes included the 10 Meter Walk Test, Modified Barthel Index, Rivermead Mobility Index, and Berg Balance Scale scores.
Results:A total of 10 patients were lost to follow-up, leaving a cohort of 48 for the final analyses. After training, all outcome measures significantly improved in both groups. In Motricity Index-Lower of the affected limb, the Morning Walk® group (∆mean ± SD; 19.68 ± 14.06) showed greater improvement (p = .034) than the control group (∆mean ± SD; 11.70 ± 10.65). And Berg Balance Scale scores improved more (p = .047) in the Morning Walk® group (∆mean ± SD; 14.36 ± 9.01) than the control group (∆mean ± SD; 9.65 ± 8.14).
Conclusion:Compared with conventional physiotherapy alone, our results suggest that voluntary strength and balance of stroke patients with hemiparesis might be improved with Morning Walk®–assisted gait training combined with conventional physiotherapy.
