Ear-Clip nerve zaps may wake hidden awareness after brain injury
NCT ID NCT07719595
First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time
Summary
Some people with severe traumatic brain injury appear unresponsive but may still be aware—a hidden state called cognitive motor dissociation. This pilot trial tests whether gentle electrical pulses delivered through clips on the left ear, stimulating two nerves at once (the vagus and trigeminal nerves), can help them recover consciousness. Ten participants receive one hour of stimulation daily for a week, with recovery measured by standard clinical scoring and an automated camera system that detects tiny voluntary movements invisible to the naked eye.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- a device that delivers gentle electrical pulses through ear-clip electrodes to stimulate the vagus and trigeminal nerves
- What this could lead to
- If it works, this could offer a non-invasive way to help people with severe brain injury recover awareness and responsiveness.
- What could go wrong
- This is a very small pilot study with only 10 participants, so results may not apply broadly. The treatment is experimental and its benefits are uncertain.
