Shoulder pain intensity and distribution

Abstract

Rotator cuff has always attracted great interest because it may be responsible for shoulder pain, loss of strength, simple or complex disabilities, partial or total inability to work, thus reducing quality of life. Several studies have been performed with the aim to understand the etiology and natural history of the lesion and how to treat it. In addition, countless studies have been conducted regarding clinical maneuvers that may help the physician to better understand if the cuff is healthy or torn; if the lesion has involved the anterior or postero-superior cuff; if it is probably a small-large or massive (repairable or unrepairable) tear; if the pain originates from the shoulder; or is caused by a cervical spine diseases.
