BRAIN–SPINE INTERFACES AFTER CERVICAL SPINAL CORD INJURY: BIDIRECTIONAL NEURAL BYPASSES, EPIDURAL STIMULATION, AND SENSORIMOTOR RESTORATION
A prospective multicenter comparative protocol was developed for adults with chronic cervical injury and neurological stability, and implanted brain–spine systems have enabled intention- driven standing and walking in an individual with chronic tetraplegia, whereas non-invasive cervical stimulation combined with task practice has improved hand strength and sensation in cohorts.
