Summary

This study tested whether a TENS device (which sends mild electrical pulses through the skin) can help people recover after laparoscopic gallbladder removal. 140 adults were randomly assigned to receive TENS or standard care in the first 24 hours after surgery. Researchers measured pain levels and patient satisfaction to see if TENS improves outcomes.

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)
What this could lead to
If it works, this could offer a drug-free way to manage pain after gallbladder surgery, reducing the need for opioids.
What could go wrong
This is a small, completed study with no phase designation, so results may not apply broadly. TENS may not work for everyone and could cause skin irritation.
