  3. Rotator Cuff Muscles • Supraspinatus • Infraspinatus • Teres minor • Subscapularis Another shoulder muscle, but not part of the Rotator Cuff: • Teres Major

  4. ROTATOR CUFF: SubscapularisTeres minor Supraspinatous Infraspinatous Subscapularis (Teres major) Teres minor (Biceps brachii)

  5. Supraspinatous Infraspinatous ROTATOR CUFF: SubscapularisTeres minor Supraspinatous Infraspinatous

  6. Rotator Cuff Injury Symptoms • Pain and tenderness in your shoulder, especially when reaching overhead, reaching behind your back, lifting, pulling or sleeping on the affected side. • Diagnosis • X-rays • MRI • Ultrasound

  7. Causes of Rotator Cuff Injuries • Normal wear and tear. • Poor posture. When you slouch your neck and shoulders forward, the space where the rotator cuff muscles reside can become smaller. This can allow a muscle or tendon to become pinched under your shoulder bones (including your collarbone), especially during overhead activities, such as throwing. • Falling. Using your arm to break a fall or falling on your arm • Lifting or pulling. Lifting an object overhead Likewise, pulling something, such as a high-poundage archery bow, may cause an injury. • Repetitive overhead movement. This occurs often in athletes, especially baseball pitchers, swimmers and tennis players. It's also common among people in the building trades, such as painters and carpenters.
