risk of failure should usually be more conservative with rehabilitations. That is followed by the "proliferative" and "maturation and remodeling" phases of healing, which ensues for the following six to ten weeks. The effect of active or passive motion during any of the phases is unclear, due to conflicting information and a shortage of clinical evidence. Gentle physical therapy guided motion is instituted at this phase, only to prevent stiffness of the shoulder; the rotator cuff remains fragile. At three months after surgery, physical therapy intervention changes substantially to focus on scapular mobilization and stretching of the glenohumeral joint. Once full passive motion is regained (at usually about four to four and a half months after surgery) strengthening exercises are the focus. The strengthening focuses on the rotator cuff and the upper back/scapular stabilizers. Typically at about six months after surgery, most have made a majority of their expected gains. The objective in repairing a rotator cuff is to enable an individual to regain full function. Surgeons and therapists analyze outcomes in several ways. Based on examinations, they compile scores on tests; some examples are those created by the University of California at Los Angeles and the American Shoulder and Elbow Surgeons. Other outcome measures include the Constant score; the Simple Shoulder Test; and the Disabilities of the Arm, Shoulder and Hand score. The tests assess range of motion and the degree of shoulder function. Due to the conflicting information about the relative benefits of rehab conducted early or later, an individualized approach is necessary. The timing and nature of therapeutic activities are adjusted according to age and tissue integrity of the repair. Management is more complex in those who have had multiple tears. Prognosis While people with rotator cuff tears may not have any noticeable symptoms, studies have shown that, those with age related tears, over time 40% will have enlargement of the tear over a five-year period. Of those whose tears enlarge, 20% have no symptoms while 80% eventually develop symptoms. Most usually regain function and experience less pain following surgery. For some, however, the joint continues to hurt. Weakness and a limited range of motion also may persist. Those who report such symptoms frequently are diagnosed with failed rotator cuff syndrome. There is no irrefutable evidence that rotator cuff surgery benefits more than non-surgical management and a percentage of individuals never regain full range of motion after
