Brief Summary

The objective of this study is to evaluate the effects of BFR training on patient reported outcome measures 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 and shoulder muscle girth than participants who are treated without BFR.

Detailed Description

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 the first physical therapy visit post-surgery. These exercises will be performed at each physical therapy session for 6 consecutive weeks (approximately 2-3 sessions/week). Standard rehabilitation will continue at the conclusion of the 6-week intervention for all participants.

Conditions

Glenoid Labrum Tear

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: DOUBLE

Study Groups

Standard Rehabilitation (Control Group)

All participants will perform traditional post-operative shoulder rehabilitation exercises. Participants randomized to this group will begin with lower extremity strengthening exercises (prior to shoulder strengthening) 2-3 times per week for for the first 6 weeks of post-operative care. Standard rehabilitation will continue until discharge.

Group Type: ACTIVE_COMPARATOR

Standard Rehabilitation

Intervention Type: OTHER

The control group will perform perform 4 sets of leg extensions and leg press (1 set of 30 repetitions followed by 3 sets of 15 repetitions) with resistance of 30% 1-repetition maximum. Sets and repetitions will remain constant for each participant; however, resistance will be incrementally increased.

Blood Flow Restriction (BFR)

All participants will perform traditional post-operative shoulder rehabilitation exercises. Participants randomized to the BFR group will begin combining BFR with lower extremity strengthening exercises (prior to shoulder strengthening) 2-3 times per week for the first 6 weeks post-operative care. Standard rehabilitation will continue until discharge.

Group Type: EXPERIMENTAL

BFR

Intervention Type: DEVICE

Delfi's Personalized Tourniquet System for Blood Flow Restriction will be used with leg extension and leg press exercises. Bilateral thigh cuffs will be applied to the participants and occlusion pressure will be set at 80% of total occlusive pressure as determined by the Doppler sensor. Each participant will perform 4 sets of each exercise (1 set of 30 repetitions followed by 3 sets of 15 repetitions) with resistance of 30% 1-repetition maximum. The pressure will remain through completion of the final set, but not to exceed 5 minutes. One minute rest without tourniquet application will be performed between exercises. Sets and repetitions will remain constant for each participant; however, resistance will be incrementally increased.
