Can a simple wrist stimulation reveal consciousness in coma?

NCT ID NCT07506928

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study aims to develop a new EEG-based technique to detect 'cognitive-motor dissociation'—where a patient is aware but cannot move. Researchers will stimulate the median nerve (in the wrist) and analyze brain signals in 50 comatose ICU patients. The goal is to identify those who may have hidden awareness, potentially improving prognosis and care.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If successful, this could lead to a new way to detect awareness in patients who appear unconscious, helping doctors give more accurate prognoses.
What could go wrong
This is a small, early-stage observational study (50 participants) that is not yet recruiting. The technique may not reliably detect awareness or improve outcomes.
