Sixth-Finger BCI Neurofeedback Aids Stroke

Summary 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.

Why it matters Most BCI rehab studies sample neural function only before and after training; this one tracks ERD week by week and ties it to clinical endpoints, a methodological step forward for mechanism-oriented stroke BCI.

BCIwiki (bciwiki.com) — Researchers report motor-function gains from a BCI-controlled sixth-finger neurofeedback intervention in stroke: 14 patients completed 8 sessions (2 weeks) of motor imagery-based BCI training, with FMA-UE rising 7.9 points and Barthel Index 7.1 points on average. The study was published in IEEE transactions on neural systems and rehabilitation engineering : a publication of the IEEE Engineering in Medicine and Biology Society on August 18, 2026.Tracking motor-imagery EEG across the full intervention, the team found a two-phase longitudinal trend in event-related desynchronization (ERD): it increased during the first week, then weakened and focused on the contralateral sensorimotor area in the second week, correlating significantly across sessions; resting-state functional connectivity increased after the intervention. More than half of the patients (9/14) reached the 6.6-point minimally clinically important difference for FMA-UE, and motor gains tracked the rise in resting-state functional connectivity. The authors say the findings offer evidence on neuroplasticity mechanisms in stroke rehabilitation.
