Shoulder Impingement Syndrome

Rotator Cuff Tear

PREVENTION/REHAB

• Depending on the injury, surgery may be necessary to fix fractures, repairing ligaments or tendons, or even pins on the outside of the elbow.

• Usually 6 weeks total worth of rehab to regain motion, flexibility, and strength in the elbow.

• Prevention

• A) Perform accessory movements that are conducive to strengthening supporting muscles

• B) Get stronger with lighter loads and adapt over time

• C) Proper execution of the lift will lead to less risk of injury
