Blood Flow Restriction (BFR)
Blood Flow Restriction (BFR) pressurized per standard protocols in addition to our institutional rehabilitation protocol
Blood Flow Restriction: In the BFR group, the tourniquet will be pressurized to 50% limb occlusion pressure (LOP), which is the pressure necessary for occluding 50% of arterial limb flow in the upper extremity.
|
"Sham" Blood Flow Restriction (BFR)
rehabilitation using "sham BFR" as well as our institutional rehabilitation protocol
"sham" Blood Flow Restriction: In the sham BFR group, the tourniquet will be pressurized to 0% occlusion pressure, while maintaining enough pressure to keep the tourniquet in place.

"sham" Blood Flow Restriction: In the sham BFR group, the tourniquet will be pressurized to 0% occlusion pressure, while maintaining enough pressure to keep the tourniquet in place.

PRIMARY outcome
Timeframe: Month 12Population: All patients lost to follow up, value never collected
Patients will receive questionnaires (VAS) at Baseline, Week 6, 6 and 12 months after completing rehabilitation - The VAS score can be interpreted into categories of pain or symptom intensity: 0-4 mm: No pain. 5-44 mm: Mild pain. 45-74 mm: Moderate pain. 75-100 mm: Severe pain.

Timeframe: BaselineThe American Shoulder and Elbow Surgeons (ASES) shoulder score is a patient-completed assessment for shoulder function and pain, ranging from 0 to 100, with higher scores indicating better function. Scoring involves a 50-point pain component derived from a visual analog scale (VAS), and a 50-point functional component from 10 activities of daily living questions, which are then weighted and added for the final score

Timeframe: BaselineThe DASH score for patients ranges from 0 to 100, with 0 representing no disability and 100 indicating the greatest possible functional impairment of the upper extremity. Patients answer a 30-item questionnaire on a five-point scale (0-4 or 0-5 depending on the scale used), rating their ability to perform tasks and their symptoms. The sum of the raw scores is then transformed into the final 0-100 DASH score
