The Effect of Brain-Computer Interface Training Based on Motor Imagery Combined with Conventional Rehabilitation on Patients with Subacute Stroke Hemiplegia
Objective: Analyzing the value of combining motor imagery brain-computer cooperative training with conventional rehabilitation in patients with hemiplegia after subacute stroke, and understanding how this approach affects patients’ upper limb movement, muscle spasticity, and daily living abilities. Methods: We selected 60 patients with subacute stroke-related hemiplegia for this study and used a random number table to divide them into groups, with 30 cases in the control group and 30 in the experimental group. The control group received conventional rehabilitation combined with upper limb motor function training, with an intervention period of 3 weeks, training 5 days per week. The experimental group, based on the same rehabilitation interventions as the control group, additionally received motor imagery BCI training, using the LSR-AⅡ brain-computer interface for standardized training. Personalized training thresholds and movements were set according to each patient’s limb dysfunction, with each session lasting 30 minutes, once a day. Results: Before intervention, there were no significant differences between the two groups in upper limb motor function, limb spasticity, daily living abilities, or fine motor function scores (p > 0.05). After intervention, both groups showed improvement in all functional scores. The experimental group showed greater improvements in Fugl-Meyer upper limb motor function scores, simplified upper limb function scores, and Barthel Index, while the observation group had higher rates of limb spasm improvement and motor function enhancement compared to the control group. The comparisons between groups showed statistically significant differences (p < 0.05). Conclusion: A comprehensive rehabilitation program combined with motor imagery brain-computer interface training can improve upper limb motor and fine functions in stroke patients and enhance their ability to take care of daily activities.
