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

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 measured how well back muscles use oxygen during exercise in people with chronic low back pain compared to healthy individuals. Researchers used special sensors to track muscle oxygen and breathing. The goal was to understand why back pain patients often feel muscle fatigue and whether a 4-week rehab program can improve muscle metabolism.

What this could mean

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

What this could lead to
If successful, this could help explain why back pain patients tire easily and point to better rehabilitation programs.
What could go wrong
This is a small, early observational study with only 33 participants. It does not test a treatment, so it may not lead to direct patient benefits.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

This study's own entry requirements. Only the study team can say for certain whether you qualify.
