BCIs Move into Orthopedic Rehab, Targeting Muscle Inhibition after Surgery
Brain-computer interfaces are moving out of neurology and into orthopedic rehabilitation, according to a review arguing that BCIs can raise corticospinal excitability and induce neuroplasticity by decoding movement-related neural signals and closing a feedback loop between central and peripheral systems. The target is postoperative muscle inhibition caused by insufficient central motor drive; available evidence suggests motor imagery-based BCI training improves quadriceps voluntary activation and limits strength loss after ACL reconstruction, though the authors cite thin mechanistic evidence, patient heterogeneity and a lack of standardized protocols as barriers to translation. The review, by researchers at the First Affiliated Hospital of Jinan University in southern China's Guangzhou and other institutions, was published on August 25, 2026, in the Chinese Journal of Reparative and Reconstructive Surgery.
