Barreto RPG, et al. - Researchers conducted this prospective study to determine comparative MRI findings across both shoulders of people with unilateral shoulder symptoms. The study sample consisted of 123 people from the community who had self-reported unilateral shoulder pain with no signs of adhesive capsulitis, no substantial range-of-motion deficit, no history of upper-limb fractures, no repeated shoulder dislocations, and no neck-related pain. In frequency between symptomatic and asymptomatic shoulders, most abnormal MRI findings were not distinct. When considering diagnostic and treatment planning, practitioners should be conscious of the common anatomic findings on MRI.
