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.

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 Results may not be published yet.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.

Summary

This study looks at whether partially blocking blood flow to the upper arm changes muscle activity when a person balances on one arm and reaches with the other. Healthy adults aged 18 to 30 will perform the test with and without a blood flow restriction device. Researchers will measure muscle signals and reach distances to understand the effect.

What this could mean

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

Active substance
a blood flow restriction device (Delfi PTS unit) that partially blocks blood flow to the upper arm
What this could lead to
If this trial shows that blood flow restriction changes muscle activity, it could point toward new rehabilitation techniques for shoulder and arm injuries.
What could go wrong
This is a small, early-stage study in healthy young adults, so results may not apply to injured people or to other age groups.
