NCT04384120

Brief Summary

The purpose of this study is to examine the effect of utilizing blood flow restriction (BFR) therapy in patients treated both non operatively and operatively for rotator cuff tears (RCT). BFR has been proposed to work by restricting arterial inflow leading to an oxygen depleted environment and the ability to induce muscle adaption at lower maximum repetition via reactive hyperemia. Muscle atrophy occurs following rotator cuff tear. Thus, physical therapy is used to regain strength with the ultimate goal of returning to activity. The goal of this investigation is to determine if using BFR during therapy for non-operatively managed and operatively managed rotator cuff tears would lead to increased and expedited strength gains. Additionally the investigators would like to determine if BFR is beneficial in preventing muscle atrophy and fatty infiltration often seen in the setting of rotator cuff tear, as it is known that cuff tears can subject the muscles to degenerative changes and these patients are at risk for poorer clinical outcomes. The investigators will also look at patient reported outcomes metrics and pain scores to determine if BFR has a significant impact on the patient experience surrounding rotator cuff tear after both nonoperative treatment with therapy and operative treatment with surgical repair and peri-operative rehabilitation. The investigators hypothesize that the BFR group will have significantly greater strength gains at all time points. Previous studies have shown that BFR has potential in increasing muscle torque generation and cross sectional area in the first six months following anterior cruciate ligament (ACL) reconstruction. While there have not been as many studies investigating the use of BFR following upper extremity surgery, previous research has demonstrate that BFR can be useful both proximal and distal to the targeted muscle groups in the upper extremity. In addition to the paucity of research on post-operative BFR following rotator cuff repair (RCR), there is no evidence on pre-operative use as well. The investigators believe that the use of BFR in the perioperative period surrounding rotator cuff tear and repair has the potential to significantly decrease muscle atrophy and lead to faster, more substantial strength gains and less muscle atrophy and fatty infiltration.

Study Arms (2)

Rotator Cuff Rehabilitation Using BFR

EXPERIMENTAL

Patients with rotator cuff tears who plan for either nonoperative treatment with physical therapy or operative treatment with arthroscopic rotator cuff repair (RCR) surgery will be randomized to undergo rehabilitation using blood flow restriction cuffs. 1. Patients who elect for nonoperative treatment of their rotator cuff tear will undergo traditional therapy using blood flow restriction cuffs. 2. Patients who elect for RCR will undergo preoperative and postoperative traditional therapy using blood flow restriction cuffs.

Device: Blood Flow Restriction Therapy

Rotator Cuff Rehabilitation Without BFR

ACTIVE COMPARATOR

Patients with rotator cuff tears who plan for either nonoperative treatment with physical therapy or operative treatment with arthroscopic rotator cuff repair (RCR) surgery will be randomized to undergo rehabilitation without using blood flow restriction cuffs. 1. Patients who elect for nonoperative treatment of their rotator cuff tear will undergo traditional therapy without using blood flow restriction cuffs. 2. Patients who elect for RCR will undergo preoperative and postoperative traditional therapy without using blood flow restriction cuffs.

Procedure: Traditional Therapy

Interventions

Blood flow restriction cuffs which are FDA approved will be provided to patients randomized into the BFR group. Patients will be provided video instruction and training on how to conduct the traditional therapy exercises with the use of BFR.
