The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Summary

This completed study tested whether a special type of electrical nerve stimulation, based on wrist-ankle acupuncture theory (TENS-WAA), can reduce pain after video-assisted lung surgery. 156 adults undergoing lung cancer surgery received either real TENS-WAA or a sham device. The goal was to see if this drug-free approach could lower pain scores and improve recovery.

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 nerve stimulation (TENS) based on wrist-ankle acupuncture theory
What this could lead to
If it works, this could provide a simple, drug-free way to reduce pain after lung surgery, potentially lowering the need for opioids and speeding recovery.
What could go wrong
This is a small, completed trial with 156 participants, so results may not apply to everyone. The effect may be modest, and the sham group might also experience some pain relief.
