Exercise-induced Hypoalgesia Effects of Blood Flow Restriction in People With Rotator Cuff-related Shoulder Pain
Sponsor: University of Valencia
Summary
This study aims to compare the effects of blood flow restricted (BFR) exercise and to examine the differences between various BFR protocols on acute pain reduction in individuals with rotator cuff-related shoulder pain, as well as the exercise tolerance at each intensity and occlusion setting. There are four exercise modalities corresponding to different combinations of intensity (%RM) and percentage of occlusion (%AOP): 1) 30% RM and 30% AOP; 2) 30% RM and 50% AOP; 3) 30% RM and 70% AOP; 4) 30% RM and BFR placebo (cuff without pressure). All participants will complete one session of each of the four exercise modalities, analyzing the variables studied in each for subsequent analysis and comparison.

Interventions
Resistance exercise with low AOP
Three exercises: external rotation at 0°, internal rotation at 0° and elevation in the scapular plane. 4 sets (30, 15, 15, reps to fatigue) with a intensity of 30% RM and a 30% of arterial occlusion pressure. 30" rest between sets, 2' rest between exercises.
Resistance exercise with moderate BFR
Three exercises: external rotation at 0°, internal rotation at 0° and elevation in the scapular plane. 4 sets (30, 15, 15, reps to fatigue) with a intensity of 30% RM and a 50% of arterial occlusion pressure. 30" rest between sets, 2' rest between exercises.
Resistance exercise with high BFR
Three exercises: external rotation at 0°, internal rotation at 0° and elevation in the scapular plane. 4 sets (30, 15, 15, reps to fatigue) with a intensity of 30% RM and a 70% of arterial occlusion pressure. 30" rest between sets, 2' rest between exercises.
Resistance exercise with sham BFR
Three exercises: external rotation at 0°, internal rotation at 0° and elevation in the scapular plane. 4 sets (30, 15, 15, reps to fatigue) with a intensity of 30% RM and a sham blood flow restriction application (cuff applied without pressure). 30" rest between sets, 2' rest between exercises.
