Participants who meet the inclusion criteria will be randomly distributed between group 1 GPR, group 2 exercise, or group 3 no physical therapy intervention.~Group 1 participants will receive a physical therapy treatment using the GPR method for 6 weeks consisting of 1 weekly session lasting 40 min performing frog on the ground and sitting poses. Patients in this group will also perform self-postures at home daily for 10 minutes.~Group 2 participants perform training for 6 weeks using non-specific aerobic exercise consisting of a daily 20-minute walk at a speed of 4-5 km/h.~Group 3 participants will not receive any physical therapy treatment and will serve as a control group.
The goal of this clinical trial is to compare in participant population (patients with rotator cuff tendinopathy of the shoulder) the effect of a Global Postural Reeducation (GPR) program vs. a nonspecific therapeutic (aerobic) exercise program
