Dual-Site Ear Nerve Stimulation for Severe Brain Injury-Related Coma

Official title: Dual-Site Transcutaneous Auricular Nerve Stimulation (taVNS + taTNS) for Disorders of Consciousness After Traumatic Brain Injury: A Pilot Efficacy Study

Run by Stony Brook University · NCT07719595 · Data updated 2026-11-12

This study tests a gentle, non-invasive stimulation on the left ear to try to help some people in coma due to severe traumatic brain injury regain awareness.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with coma, VS/UWS, or MCS due to acute traumatic brain injury, in ICU, with a legally authorized representative able to consent for stimulation.

Probably not a fit

Patients without responsiveness to the dual-site stimulation or without suitable ear anatomy or safety conditions may not experience benefit.

What this trial studies

This is a prospective, single-center, open-label pilot study enrolling comatose TBI patients whose consent is provided by a legally authorized representative. The intervention combines two non-invasive ear stimulations (taVNS and taTNS) delivered for one hour daily over 7 days, with potential extension up to 28 days, and continuous safety monitoring. Outcomes are assessed with the Coma Recovery Scale-Revised (CRS-R) and SeeMe, an automated camera system that detects subtle, stimulus-driven movements. The study aims to determine if dual-site stimulation can enhance arousal and thalamocortical connectivity, informing a future sham-controlled trial and integration with SeeMe. Baseline and daily assessments include vital signs, EEG, heart-rate variability, and neurobehavioral scales.

Why it matters

Potential benefit: If successful, the approach could improve signs of consciousness and inform future therapies for patients with hidden awareness after severe brain injury.

How similar studies have gone: Previous single-site stimulation approaches have shown signals of arousal in disorders of consciousness, but dual-site stimulation is novel in this context and its effectiveness has not been proven yet.
