Rotator cuff tear oxidative stress induces tenocyte apoptosis causing further rotator cuff tendon degeneration. A neural theory also exists that suggests neural overstimulation leads to the recruitment of inflammatory cells and may also contribute to tendon degeneration. Tears of the rotator cuff tendon are described as partial or full thickness, and full thickness with complete detachment of the tendons from bone. Shoulder pain is variable and may not be proportional to the size of the tear. Neer promoted the concept of three stages of rotator cuff disease. Stage I, according to Neer, occurred in those younger than 25 years and involved edema and
Rotator cuff tear large full thickness rotator cuff tears. Rehabilitation after surgery consists of three stages. First, the arm is immobilized so that the muscle can heal. Second, when appropriate, a therapist assists with passive exercises to regain range of motion. Third, the arm is gradually exercised actively, with a goal of regaining and enhancing strength. Yoshitsugu Takeda and his team have recently studied rotator cuff injuries and rehab exercises that target the supraspinatus. As mentioned earlier, the supraspinatus muscle is the muscle and tendon within the rotator cuff that is most often injured. In order to rehab the supraspinatus and combat future
