Effects of a 4-week Low-intensity Training With Blood Flow Restriction in People With Rotator Cuff-related Shoulder Pain

This study aims to analyze the effects of 4 weeks of low-intensity exercise with and without blood flow restriction (BFR) on pain, fear of movement, catastrophizing about pain, strength, and disability in a population with rotator cuff-related shoulder pain. There are two modalities corresponding to the same exercises under different blood flow restriction conditions: 1) 3 low-intensity exercises (30% 1RM) with BFR (50% AOP); 2) 3 low-intensity exercises (30% 1RM) without BFR. Participants will be randomly assigned to one of two groups and will undergo a 4-week intervention. The variables of interest will be assessed in each group for subsequent analysis and comparison.
