简要总结
The goal of this clinical trial is to identify any differences in elbow ulnar collateral ligament (UCL) relative thickness and joint space laxity in the dominant arm following an 8-week course of low intensity resistance exercises with blood flow restriction (BFR) exercises in healthy volunteers. The main questions it aims to answer are:
- Do BFR exercises contribute to a change in the relative ligament thickness of the UCL, and changes in the ulnohumeral joint space?
- Are there changes in arm strength following the 8-week strengthening protocol with/without BFR?
Participants will:
- Complete two BFR sessions a week for a total of eight weeks.
- Complete an exercise session with both arms (dominant arm will receive BFR) at each study visit.
- Have sonographs taken of the UCL at the first and last study visit.
- Complete strength assessments at the first and last study visit.

结局指标
主要结局
Relative ligament thickness of the UCL
时间窗: From baseline visit to end of treatment at 8 weeks
Ligament thickness will be evaluated by ultrasound imaging measurement.
Changes in the ulnohumeral joint laxity
时间窗: At 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.
次要结局
- Changes in arm strength(From baseline visit to end of treatment at 8 weeks)
