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 This study
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
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study investigates whether increased muscle tone in the legs can predict neurogenic detrusor overactivity (NDO)—a condition where the bladder contracts involuntarily—in adults with upper sacral spinal cord injury. Researchers will compare medical records of 300 patients with and without leg muscle tightness to see if muscle tone independently predicts NDO. The study is observational and retrospective, meaning it only reviews existing data from routine care, without any new tests or treatments.

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 leg muscle tone proves to be a reliable predictor, it could help doctors identify bladder problems earlier in people with spinal cord injury, potentially improving care.
What could go wrong
This is a retrospective observational study, so it can show associations but not cause and effect. The findings may not apply to all patients or settings.

Who can take part

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

Who is studied

This study looks at adults aged 18 to 80 with suprasacral Spinal Cord Injury who stayed at the Shengjing Hospital of China Medical University from January 2020 to January 2025. All participants have full medical records, including neurological exams, Modified Ashworth Scale checks, and urodynamic test results. Anyone missing key data or with assessments spaced out by more than two weeks was left out.

Ages

16 to 80 years
