Blood Flow Restriction Training on the Ulnar Collateral Ligament (UCL)

This study is looking at how Blood Flow Restriction (BFR) training affects the ulnar collateral ligament (UCL) in your elbow. Researchers want to see if using a special device called the Delfi PTS Blood Flow Restriction Tourniquet System during low-intensity exercises changes the thickness of your UCL and the space in your elbow joint. They also want to know if this training improves arm strength. You can join if you are a healthy volunteer between 18 and 50 years old, without recent injuries to your hand, elbow, or shoulder, or certain vascular conditions. The study will measure changes in your UCL thickness and elbow joint laxity after 8 weeks of treatment.

Study design
This interventional study plans to enroll 50 healthy male and female volunteers. It is not specified if the study is randomized or blinded.
What's involved
You will complete two BFR sessions a week for eight weeks. Each session involves exercising both arms, with your dominant arm receiving BFR.
Compensation
Not stated in the trial record.
Follow-up
Your UCL thickness and elbow joint laxity will be measured at the end of treatment at 8 weeks.

What this trial measures

  • Relative ligament thickness of the UCLFrom baseline visit to end of treatment at 8 weeks

    Ligament thickness will be evaluated by ultrasound imaging measurement.

  • Changes in the ulnohumeral joint laxityAt baseline visit and end of treatment at 8 weeks

    Any changes will be evaluated by ultrasound imaging. To calculate the relative measurement, also known as the side-to-side difference (STS), investigators will take measurements from both the dominant and nondominant arms and then calculate difference between the two.
