Combined BCI and Gait-Robot Training Beats Either Alone in Stroke Trial
A randomized controlled trial in 120 patients with post-stroke hemiplegia found that pairing brain-computer interface (BCI) rehabilitation training with a gait robot accelerated lower-limb recovery and improved muscle activation patterns more than either intervention on its own. After eight weeks, BCI training, gait-robot training and the combination all improved lower-limb motor function, muscle activity and gait compared with routine training, but the combined group showed the largest increases in integrated electromyography of the tibialis anterior and gastrocnemius, along with a greater gain in step frequency and a greater reduction in step width.
Why it matters
Head-to-head comparisons are rare in stroke rehabilitation, and evidence that BCI and robotic gait training work better together than separately recasts the two systems as complementary purchases rather than competing ones for rehabilitation departments choosing where to spend.
