What this Trial Is About
Researchers are evaluating how low intensity resistance exercises combined with blood flow restriction (BFR) affect the thickness of the elbow ulnar collateral ligament (UCL) and joint space flexibility in the dominant arm. This study aims to determine whether BFR exercises change the ligament thickness and ulnohumeral joint laxity, as well as if arm strength improves after an 8-week exercise program. Healthy adults between 18 and 50 years old are invited to participate. Participants will complete two BFR exercise sessions per week for eight weeks, focusing on both arms but applying BFR only to the dominant arm. The intervention uses the Delfi PTS Blood Flow Restriction Tourniquet System, which is commonly used in rehabilitation settings. The study observes changes from baseline to the end of treatment, particularly measuring ligament thickness and joint laxity. During the study, participants will have ultrasound scans of the UCL and strength assessments at the beginning and end of the 8-week treatment period. The researchers will monitor changes in ligament thickness, joint laxity, and arm strength to understand the effects of BFR training. The total participation time spans the 8-week exercise program with assessments at two key visits.
