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 Results may not be published yet.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
Cancelled before anyone took part.

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

This study looks at how two common treatments for myofascial jaw pain—a mouth splint and lidocaine injections—affect the muscles of the jaw and neck. Researchers use ultrasound to see changes in muscle structure, like how well the muscle fibers reflect sound waves. The goal is to find out if ultrasound can help measure whether a treatment is working. The study includes 80 people with myofascial pain who have not had treatment in the last three months.

What this could mean

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

Active substance
occlusal splint and lidocaine injection
What this could lead to
If successful, this could show that ultrasound can track muscle healing, helping doctors choose better treatments for jaw and neck pain.
What could go wrong
This is a small, early-stage study with no placebo group, so results may not prove which treatment works best or apply to everyone.
