ABSTRACT

Objective : This study examined the effects of Electromyography (EMG)-based robotic training with visual feedback on hand function and Activities of Daily Living (ADL) performance in individuals with chronic stroke. Methods : Twenty individuals with chronic stroke were randomly assigned to an EMG-based training group (n = 10) or a continuous passive training group (n = 10). Both groups received therapy and robotic training three times per week for 30 minutes over 6 weeks. Outcomes included the Fugl-Meyer Assessment–Upper Extremity, Manual Function Test, Box and Block Test (BBT), grip strength, and Korean version of Modified Barthel Index. Wilcoxon signed-rank and Mann–Whitney U tests were used. Results : The experimental group showed significant improvements in hand function, grip strength, and ADL performance (p < 0.05). The control group showed significant improvements in grip strength and BBT scores but not in other outcomes. Between-group comparisons showed greater improvements in the experimental group (p < 0.05). Conclusion : EMG-based robotic training with visual feedback improved hand function and ADL performance in individuals with chronic stroke.
