Editing Rotator cuff (section)

===Tear===
{{Main|Rotator cuff tear}}
The tendons at the ends of the rotator cuff muscles can become torn, leading to [[pain]] and restricted movement of the arm.  A torn rotator cuff can occur following trauma to the shoulder or it can occur through the "wear and tear" on tendons, most commonly the supraspinatus tendon found under the [[acromion]].

Rotator cuff injuries are commonly associated with motions that require repeated overhead motions or forceful pulling motions. Such injuries are frequently sustained by athletes whose actions include making repetitive throws, athletes such as [[Handball|handball players]], [[baseball]] [[pitcher]]s, [[softball]] [[pitchers]], [[American football]] players (especially [[quarterback]]s), [[firefighter]]s, [[cheerleaders]], weightlifters (especially [[powerlifters]] due to extreme weights used in the [[bench press]]), [[Rugby football|rugby]] players, [[volleyball]] players (due to their swinging motions),{{citation needed|date=June 2012}} [[water polo]] players, rodeo [[team roping|team ropers]], [[shot put]] throwers, [[swimmers]], [[Boxer (boxing)|boxer]]s, [[kayaker]]s, [[martial arts|martial artists]], [[Fast bowling|fast bowlers]] in cricket, [[tennis]] players (due to their service motion){{citation needed|date=June 2012}} and [[Tenpin Bowling|tenpin bowlers]] due to the repetitive swinging motion of the arm with the weight of a [[bowling ball]]. This type of injury also commonly affects [[orchestra conductor]]s, [[choral conductor]]s, and [[drummer]]s (due, again, to swinging motions).

As progression increases after 4–6 weeks, active exercises are now implemented into the rehabilitation process. Active exercises allow an increase in strength and further range of motion by permitting the movement of the shoulder joint without the support of a physical therapist.<ref name="Jobe, F.M. 1992">{{cite journal |vauthors=Jobe FW, Moynes DR |title=Delineation of diagnostic criteria and a rehabilitation program for rotator cuff injuries |journal=Am J Sports Med |volume=10 |issue=6 |pages=336–9 |year=1982 |pmid=7180952 |doi=10.1177/036354658201000602|s2cid=41784933 }}</ref> Active exercises include the Pendulum exercise, which is used to strengthen the Supraspinatus, Infraspinatus, and Subscapularis.<ref name="Jobe, F.M. 1992" /> External rotation of the shoulder with the arm at a 90-degree angle is an additional exercise done to increase control and range of motion of the Infraspinatus and Teres minor muscles. Various active exercises are done for an additional 3–6 weeks as progress is based on an individual case-by-case basis.<ref name="Jobe, F.M. 1992" /> At 8–12 weeks, [[strength training]] intensity will increase as free-weights and resistance bands will be implemented within the exercise prescription.<ref name="Escamilla09" />
