Three Weeks of Motor Imagery BCI Improves Arm Function in Subacute Stroke
A study of 60 patients with subacute stroke hemiplegia found that adding motor imagery brain-computer interface training to conventional rehabilitation significantly improved upper limb motor function, simplified upper limb function scores, and daily living abilities. The experimental group of 30 received 3 weeks of additional BCI training, 5 days per week, while the control group received only conventional rehabilitation. The experimental group showed greater improvements in Fugl-Meyer upper limb scores, simplified upper limb function scores, and Barthel Index, with statistically significant differences.
