Ongoing
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

Researchers are studying whether TENS, a device that sends mild electrical pulses through the skin, can lower pain and reduce the need for painkillers after total hip replacement. The trial enrolls 60 adults who have had hip replacement surgery and do not have a pacemaker, heart rhythm problems, or a history of chronic pain or substance abuse. On the first two days after surgery, participants in the treatment group receive TENS, and researchers measure their pain at rest and during movement along with how much pain medicine they use.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
TENS, a device that delivers mild electrical pulses through the skin to nerves
What this could lead to
If TENS helps, nurses could offer a simple, drug-free way to ease pain after hip replacement and cut how much painkiller patients need.
What could go wrong
This is a small, single-center study of 60 people, so the results may not hold for everyone. TENS does not work for all patients, and it cannot be used by people with a pacemaker or certain heart rhythms.
