Blood Flow Restriction Training Following Glenoid Labral Repair

06 May 2020

The objective of this study is to evaluate the effects of BFR training on patient reported outcome measures, shoulder strength & range of motion, and shoulder muscle girth in patients following glenoid labral repair. The investigators hypothesize that participants receiving BFR with rehabilitation will have greater improvements in patient reported outcome measures, shoulder strength, range of motion, and shoulder muscle girth than participants who are treated without BFR. Patients between the ages of 18 and 55 who had a superior labrum anterior to posterior (SLAP) repair, anterior labral repair, anterior capsulorrhaphy, or posterior labral repair will be screened for participation in this study. Participants will be randomized in a 1:1 ratio to receive standard physical therapy with blood flow restriction training or without blood flow restriction. Participants will receive standard of care rehabilitation for labral repair regardless of group assignment. The length of each physical therapy session will be approximately one hour. The BFR and control group will perform leg press and leg extension exercises prior to shoulder strengthening. The resistance for both groups will be set as 30% of one repetition maximum (1-RM). The goal will be for the participants to perform 4 sets of repetitions sequenced 30, 15, 15, 15 of each exercise, if this is not obtainable then the number of set/repetitions will be decreased. The lower extremity strengthening exercises for this study will be performed by all participants beginning at 4 weeks post-surgery. These exercises will be performed at each physical therapy session for 8 consecutive weeks (approximately 2 sessions/week). Standard rehabilitation will continue at the conclusion of the 8-week intervention for all participants.
