Clinical task
Motor-imagery based neurofeedback uses the desynchronization of the sensorimotor rhythm and enables direct brain–computer communication without muscular activity [1].
In chronic stroke, brain–machine interface training with movement intent is associated with clinical improvement [2].
| Stage | Duration |
|---|---|
| Screening | 1 week |
| Training | 4 weeks, 3–4 sessions/week |
| Follow-up | 3 months |
Equipment
Brain–computer interfaces are also used for communication and restoration of movement in paralysis [3]; sessions were performed with our EEG amplifiers and caps.
