What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
non-invasive nerve stimulation via TENS unit
What this could lead to
If it works, this could offer a new, non-drug way to improve sleep for veterans with PTSD.
What could go wrong
This is a small, early-stage study with 87 participants and no placebo group, so results may not apply widely. The effect on sleep may be modest.
