Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
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 Results may not be published yet.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.
Cancelled

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

Researchers at the University of Hartford are testing whether adding high-intensity electromyostimulation (Hi-EMS) to TECAR therapy, a treatment that uses electrical energy to warm tissue, helps adults with chronic nonspecific low back pain. Participants receive both TECAR alone and TECAR plus Hi-EMS in random order, with a week between sessions. The team measures pain at rest, pain during a sit-to-stand test, pressure pain threshold, and functional performance before and after each session.

What this could mean

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

Active substance
TECAR therapy with or without high-intensity electromyostimulation
What this could lead to
If adding Hi-EMS helps, it could give physical therapists a stronger non-drug option for easing chronic low back pain and improving movement.
What could go wrong
This is a small, short-term study of 37 people, so any benefits may be modest or fade, and results may not apply to other back pain patients. Electrical therapies can cause skin irritation or discomfort.
