Beijing Tiantan Hospital Registers BCI Robot Mirror-Therapy Trial in 40 Stroke Patients
The trial combines a brain-computer interface with robotic mirror therapy into a single intervention, while the control arm receives conventional comprehensive rehabilitation only. It enrolls patients aged 30 to 80 with unilateral upper-limb motor impairment 1 to 6 months after ischemic or hemorrhagic stroke, whose lesions are confined to the basal ganglia. The primary endpoint is the Fugl-Meyer Assessment of the Upper Extremity, with EEG, functional MRI and the Modified Ashworth Scale among secondary measures. The planned enrollment is 40 patients, with first enrollment set for May 1, 2026.
Why it matters
Bundling a brain-computer interface with robotic mirror therapy into one intervention is what sets this trial apart from most BCI stroke-rehabilitation studies, which typically pair motor imagery with an exoskeleton or electrical stimulation. By restricting enrollment to basal ganglia lesions and a 1-to-6-month post-stroke window, it narrows the population to patients whose corticospinal tract is relatively intact. The primary endpoint is the upper-extremity Fugl-Meyer score. Enrollment is planned at 40 patients, with first enrollment set for May 1, 2026; recruitment has not yet begun.
