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.

Experimental: Rotator Cuff Rehabilitation Using BFR
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.
Device: Blood Flow Restriction Therapy
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.
Active Comparator: Rotator Cuff Rehabilitation Without BFR
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.
Procedure: Traditional Therapy
Patients will be provided video instruction and training on how to conduct the traditional therapy exercises.
- Strength [ Time Frame: through study completion, an average of 12 months post-operative follow-up ]Strength will be quantified through dynamometers
- Range of Motion [ Time Frame: through study completion, an average of 12 months post-operative follow-up ]Range of motion of the shoulder will be assessed using a goniometer
- Pain Score [ Time Frame: through study completion, an average of 12 months post-operative follow-up ]Pain will be assessed using a visual analogue scale (VAS), a pain scale from 0-10 where higher numbers indicate worse pain
- Patient reported outcomes measurement information system [ Time Frame: through study completion, an average of 12 months post-operative follow-up ]Patient reported outcome measurement information system (PROMIS) scores will be collected through a series of questionnaires from the PROMIS domain of physical function, upper extremity, and depression. These scores are standardized T-scores with the mean set at 50 and the standard deviation set at 10.
- Rotator Cuff Integrity [ Time Frame: through study completion, an average of 12 months post-operative follow-up ]Fatty infiltration and muscle atrophy of the rotator cuff will be measured by ultrasound and compared to preoperative imaging
- ASES Outcome Score [ Time Frame: through study completion, an average of 12 months post-operative follow-up ]American shoulder and elbow surgeons standardized shoulder assessment form is a 100-point scale that consists of a pain scale worth 50 points and ten activities of daily living worth 50 points.
