Sixth-Finger BCI Neurofeedback Aids Stroke
Researchers report that a BCI-controlled sixth-finger neurofeedback intervention improved motor function in stroke: after 8 sessions (2 weeks) of motor-imagery BCI training, 14 patients gained an average of 7.9 points on FMA-UE and 7.1 on the Barthel Index, with 9 of 14 reaching the 6.6-point minimally clinically important difference. EEG tracking across the full intervention showed a two-phase ERD trend that strengthened in week one and narrowed to the contralateral sensorimotor area in week two, and resting-state functional connectivity rose afterward, correlating with motor gains. The authors say the work offers longitudinal evidence on neuroplasticity in stroke rehabilitation.
