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 This study
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 Results may not be published yet.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
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 trial investigates whether adding specific lumbar extension strengthening exercises to standard physical therapy (manual therapy and motor control exercises) can further reduce disability and improve back muscle function in adults with chronic low back pain. Sixty participants will receive eight weeks of physical therapy, with half also doing targeted low back strengthening. Researchers will measure changes in disability, muscle thickness, endurance, and healthcare use to see if the extra exercises make a meaningful difference.

What this could mean

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

Active substance
lumbar extension strengthening exercises added to standard physical therapy (manual therapy and motor control exercises)
What this could lead to
If adding these exercises proves effective, it could lead to a more targeted physical therapy approach for chronic low back pain, potentially reducing disability and reliance on other healthcare.
What could go wrong
This is a relatively small, early-stage trial (60 participants) comparing two non-drug treatments. The added exercises may not provide significant extra benefit over standard therapy alone, and results may not apply to all back pain patients.
