Efficacy and Circuit Mechanisms of Noninvasive Brain-Computer Interface Therapy for Upper-Extremity Motor Function in Patients With Ischemic Stroke (BRACING)
This prospective, single-center, single-arm exploratory clinicaltrial will enroll participants with upper-extremity dysfunction after chronicischemic stroke. A total of 38 participants are planned. All enrolled participants will receive noninvasive brain-computer interface (BCI)-controlled exoskeleton training for 4 weeks, once daily, 5 days per week. Upper-extremity motor function will be assessed using the Fugl-Meyer Assessment for the Upper Extremity (FMA-UE), the Action Research Arm Test (ARAT), and other measures. The study aims to: (1) preliminarily evaluate the efficacy of noninvasive BCI-controlled exoskeleton training in promoting upper-extremity motor recovery after chronic ischemic stroke; and (2)use multimodal neuroimaging and electrophysiological techniques to clarify the regulatory role of the reward-motor circuit in BCI-induced motor learning and functional recovery, and to explore key neural biomarkers and predictive models associated with treatment response.

실험적: BCI-induced Group
Patients with upper-extremity dysfunction after ischemic stroke. |
All eligible patients with upper-extremity dysfunction after chronic ischemic stroke will receive the study treatment once daily, 5 days per week, for 4 weeks. The intervention uses the BCI system together with the active passive exoskeleton training system. The clinical management platform will be used for participant enrollment, assessment, treatment planning, and data archiving. |
