Background: People with shoulder pain can present compensatory biomechanical strategies that can cause an overload in the shoulder region as in other body segments and this could be the origin of a cycle in which one site of pain worse other sites. However, there are no studies that have investigated the prevalence of concomitant pain in other regions of the body in patients with shoulder pain.
Purpose: To investigate the prevalence of concomitant musculoskeletal pain in patients with shoulder pain.
Methods: It was a cross-sectional study in which it were assessed 299 patients (60.64 ± 8.77 years old) diagnosed with rotator cuff dysfunction (tendinopathy, partial or full-thickness tear) from traumatic or degenerative etiology with the beginning of the shoulder region pain for at least 3 months. The complaint of other musculoskeletal pain in addition to the shoulder pain was investigated through a questionnaire. Prevalence of concomitant pain was calculate as percentage.
Results: 75.9% of subjects with shoulder pain presented any complaints associated musculoskeletal pain; 49% had complaints of pain in the lower back and 35% on knees. The other body segments, except neck (13%) were less than 8%.
Conclusion(s): There is a high prevalence of musculoskeletal complaints of pain in lower back, knees and other regions of the body in patients with shoulder pain. The most prevalent concomitant pain were in lower back and knees.
Implications: The results of this study suggest that it is important to investigate the existence of concomitant pain in different regions of the body that could be overload due compensatory mechanism. New studies are necessary to assess the motor control and stability of the other segments involved in order to better understand the biomechanics origin of pain and its relationship with the shoulder pain.
