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

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 Results may not be published yet.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 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.

Summary

This completed study compared how well people with complex regional pain syndrome (CRPS), people with other muscle or bone pain, and healthy individuals can imagine movements. Researchers used a questionnaire called the MIQ-RS to measure motor imagery skills. The goal was to see if CRPS patients have more trouble with mental movement tasks, which could affect their rehabilitation.

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 doctors better understand and assess motor imagery problems in CRPS patients, potentially improving rehabilitation approaches.
What could go wrong
This is a small, completed pilot study with no treatment being tested. The questionnaire is not yet a standard diagnostic tool, and results may not apply broadly.

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