University Hospital, Grenoble Registers Chronic BCI Study for Speech Rehabilitation in Locked-In Syndrome
Grenoble University Hospital has registered a clinical study (NCT07698496) assessing the feasibility and effectiveness of a chronic brain-computer interface for speech rehabilitation in people with locked-in syndrome (LIS), where non-invasive communication carries high cognitive load and existing invasive speech BCIs still rely on percutaneous connectors with infection risk. Using an intracranial epidural BCI paired with a speech synthesizer, the SpeechBCI protocol will test two complementary approaches in the same subject — a speech BCI (primary objective, the BCI_PAROLE device) and a cursor BCI (secondary), both running on the WIMAGINE intracranial epidural system. The trial is in the registration stage and has no clinical results yet.
