At-Home BCI Therapy Beats Home Exercise for Chronic Stroke Arm Deficits in Randomized Trial
Chronic stroke patients who used an at-home brain-computer interface (BCI) therapy system gained a mean 6.0 points on the Upper Extremity Fugl-Meyer Assessment after 12 weeks, versus 1.5 points for those on a home exercise program. Response rates were 55.5% and 9.6%, for a number needed to treat of 2.2. The trial also exposed the dropout problem in home-based studies: 17 of 42 control participants withdrew because they were dissatisfied with their group assignment.
