Injuries to the Rotator Cuff
Having continuous employment as a painter or an occupation where it is necessarily to always be reaching above their head are usually at great risk to experience a tearing and great amount of pain in their shoulder usually caused by a injury in one of the four muscles that together make up what is called the rotator cuff.. Athletes are also especially vulnerable to overuse tears, particularly tennis players and baseball pitchers.
The rotator cuff is made up of a group of 4 muscles; the names of those muscles are supraspinatus, infraspinatus, subscapularis, and the teres minor. These muscles together help you when it comes to needing to lift your shoulder up over your head and also rotate it toward and away from your body. Unfortunately, one of the downsides of the rotator cuff is that it is also a group of muscles that is frequently injured by tears, tendonitis, and strains. The major muscle that is usually involved when it comes to the damage is called the supraspinatus muscle.
“The supraspinatus is a relatively small muscle of the upper arm that runs from the supraspinatous fossa superior of the scapula (shoulder blade) to the greater tubercle of the humerus. It is one of the four rotator cuff muscles and also abducts the arm at the shoulder. The spine of the scapula separates the supraspinatus muscle from the infraspinatus muscle, which originates below the spine” (Supraspinatus Muscle, 2013)
Rotator Cuff Tendonitis/tears usually occur in people 30-80 years of age, and the weakness starts out in the shoulder as only mild to moderate. Rotator cuff tendonitis, also known as “impingement syndrome “occurs when the rotator cuff gets irritated. They say this issue is arises because rotator cuff weakness causes the humorous to ride up and pinch the cuff. A lot of the time there are no issue with tendons in this small space but “In some people this space becomes too
