What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
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 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 Results may not be published yet.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.
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.

Summary

This study tested two different low-level laser wavelengths (635nm and 980nm) to see if they could reduce pain and improve jaw function in people with myofascial pain syndrome of the jaw. Thirty participants received laser treatment twice a week for five weeks. The main goal was to measure pain reduction and how well the jaw could open.

What this could mean

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

Active substance
low-level laser therapy (635nm or 980nm diode laser)
What this could lead to
If successful, this could point toward a non-drug, non-invasive option for reducing jaw muscle pain and improving mouth opening.
What could go wrong
This is a small, completed trial with only 30 participants, so results may not apply to everyone. Pain relief from laser therapy can vary, and long-term benefits are not yet proven.
