Can a tiny zing at your fingertips wake the brain? new trial aims to find out
NCT ID NCT07535593
First seen Jun 26, 2026 · Last updated Aug 06, 2026 · Updated 3 times
Summary
This study tests whether a mild, painless electrical stimulation at specific acupoints on the hands can help people with disorders of consciousness after severe brain injury. The treatment is given daily for 14 days. Researchers will compare the stimulation to a sham (fake) treatment to see if it safely improves awareness. The trial plans to enroll 160 adults aged 18-80.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcutaneous electrical acupoint stimulation (TEAS) at hand Jing-Well points
- What this could lead to
- If it works, this could offer a safe, noninvasive way to help some patients with disorders of consciousness regain awareness.
- What could go wrong
- This is an early-stage trial with only 160 participants. A previous smaller study did not show a clear benefit, so results may not be conclusive.
