Abstract: Study explored the safety and feasibility of a foot-drop-targeted brain-computer interface (BCI)-controlled functional electrical stimulation (FES) physical therapy in chronic stroke survivors. Nine subjects operated an electroencephalogram-based BCI-FES system for foot dorsiflexion in 12 one-hour sessions over four weeks. Gait speed, dorsiflexion active range of motion (AROM), six-minute walk distance (6MWD), and Fugl-Meyer leg motor (FM-LM) scores were assessed before, during, and after therapy. The primary safety outcome measure was the proportion of subjects that deteriorated in gait speed by ≥0.16 meters per second at one week or four weeks post-therapy. The secondary outcome measures were the proportion of subjects that experienced a clinically relevant decrease in dorsiflexion AROM (≥2.5 degrees), 6MWD (≥20 percent), and FM-LM score (≥10 percent) at either post-therapy assessment. None of the subjects experienced a clinically significant deterioration in gait speed, dorsiflexion AROM, 6MWT distance, or FM-LM score at either post-therapy assessment. Five subjects demonstrated a detectable increase in gait speed, three subjects demonstrated a detectable increase in dorsiflexion AROM, five subjects demonstrated a detectable increase in 6MWD, and three subjects demonstrated a detectable increase in FM-LM. Linear mixed models of gait speed, dorsiflexion AROM, 6MWD, and FM-LM scores suggest that BCI-FES therapy is associated with an increase in lower motor performance at a statistically, yet not clinically, significant level. BCI-FES therapy appears to be safe. If it is shown to improve post-stroke gait function in future studies, it could provide a new gait rehabilitation option for severely impaired patients.
