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.

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 Results may not be published yet.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.

Summary

People with spinal cord injury (SCI) face higher risks of heart disease and diabetes, partly due to chronic inflammation and poor blood vessel function. Exercise helps but is often not possible. This small study tested whether repeated passive heating (using a water-perfused suit or electric blanket) three times a week for eight weeks could lower inflammation and improve metabolism and blood vessel health in 10 adults with stable SCI. The goal was to see if this simple, accessible method could reduce key risk factors for heart disease and diabetes.

What this could mean

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

Active substance
passive heat stress (water perfused suit or electrical heating blanket)
What this could lead to
If it works, this could offer a simple, accessible way to lower heart disease and diabetes risk in people with spinal cord injury who cannot exercise.
What could go wrong
This is a very small, early study (10 participants) with no control group for comparison. The benefits seen may not be large or lasting, and longer-term effects are unknown.
