Case Report: 3 Stroke Patients Gain Arm Function After 24 BCI-FES Sessions
Three stroke patients with hemiplegia improved on upper-limb motor scores and daily-living measures after 24 sessions of visually guided brain-computer interface training paired with functional electrical stimulation, according to a case report. The patients trained five times a week, and stimulation fired only when the system detected motor imagery-related EEG patterns; gains appeared on Brunnstrom stages, the Fugl-Meyer Assessment and the Barthel Index, most clearly in wrist and hand control. The report cautions that the findings are preliminary and require validation in larger randomized controlled trials.
