Abstract
We present the feasibility of a complete rehabilitation system based on brain computer interface (BCI) triggered functional electrical stimulation (FES) and avatar mirroring to improve the function of the paretic limbs. The system was tested on two chronic stroke patients with 25 BCI training sessions over 13 weeks. The Upper-Extremity Fugl-Meyer Assessment (FMA-UE) and the Modified Ashworth Scale (MAS) were improved in both patients, however, one patient showed more improvement than the other, for whom the longer time since the stroke (31 years vs. 4 years), no residual motor function in the paretic wrist, and poor BCI performance may have limited recovery. Randomized controlled studies are necessary to show the effectiveness of the BCI-FES-avatar system with a larger sample size and matched parameters between test and control groups.
