Objectives:
To evaluate the effectiveness of robot-assisted therapy (RAT) followed by activities of daily living (ADL) training in comparison with conventional rehabilitation therapy (CRT) and ADL training in individuals with subacute stroke.
Design:
A single-blind, 2-arm, parallel-group, open-level, randomized controlled trial.
Setting:
A tertiary care teaching hospital in India.
Participants:
Forty-four persons (n=44) with first-ever stroke (in subacute stage) were enrolled from August 2021 to July 2023.
Intervention:
Participants in the RAT group (n=22) received RAT for 30 minutes, followed by ADL training for 30 minutes. In contrast, participants in the CRT group (n=22) received CRT (30 minutes) followed by ADL training (30 minutes). Both groups received allocated interventions for 15 days over 3 weeks (5 days/week, 3 weeks).
Main Outcome Measures:
Primary outcome: Motor domain score of the Fugl-Meyer Assessment scale for upper extremity (FMA-UE).
Secondary Outcomes:
the other domains scores of FMA-UE (UL -sensation, -joint motions, -joint pain); Modified Ashworth Scale (MAS) (spasticity); hand-function (HF) and ADL-domain scores of the stroke impact scale (SIS); WHOQQL-BREF questionnaires (QOL). Participants were assessed at enrolment and follow-up at 3, 6, and 12 weeks.
Results:
Persons who received RAT and ADL training reported significant improvement (P<.05) in UL motor function (mean difference [MD]=3.54;(95% confidence interval [CI]: 1.28 to 5.79]), UL passive joint motions (MD=2.54; [95% CI: 1.56 to 3.52]), SIS-HF (MD=6.37;[95% CI: 4.75 to 7.99]), SIS-ADL (MD=7.13 [95% CI: 3.52 to 8.74]), and in all domains of WHOQOL-BREF (except environmental domain) compared with persons who received CRT and ADL training at 12 weeks.
Conclusions:
The findings indicate that RAT followed by ADL training is more effective than CRT followed by ADL training in motor improvement, SIS-HF, SIS-ADL, and QOL at 12 weeks.
