 Brain-computer interface, BCI-based rehabilitation has shown promise in helping stroke survivors regain lost motor skills. However, some stroke patients are unable to achieve the necessary BCI performance needed to benefit from these treatments. A new study suggests that adaptive BCI-based functional electrical stimulation, FES, can help these patients recover more effectively than traditional FES alone. The researchers found that stroke patients with low BCI performance showed similar levels of improvement as those with higher BCI performance when using adaptive BCI-based FES. This suggests that adaptive BCI-based FES could be used to help stroke patients who struggle with BCI performance to still benefit from BCI-based rehabilitation treatments.
