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
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 Results may not be published yet.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

This study tested whether a single session of high-intensity interval training (three 20-second all-out efforts on an arm bike) could improve heart and brain function in 30 people with spinal cord injury compared to uninjured controls. The goal was to see if this type of exercise helps regulate blood pressure and sharpen thinking. Results are not yet available.

What this could mean

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

Active substance
high-intensity interval exercise
What this could lead to
If successful, this could point toward exercise-based strategies to improve heart and brain health in people with spinal cord injury.
What could go wrong
This is a small, early-stage study with only 30 participants, looking at immediate effects of a single exercise session. Results may not apply to long-term training or to all types of spinal cord injury.
