Internal rotation, external rotation and supraspinatus are exercises that help with shoulder impingement tindinitis, explains the Palo Alto Medical Foundation. Range of motion exercises, such as the pendulum swing, and stretching exercises also help, reports Sierra Pacific Orthopedics.
Shoulder impingement tendinitis occurs when the tendons in the rotator cuff of the shoulders become inflamed or damaged, according to the American Academy of Orthopaedic Surgeons. Range of motion exercises for shoulder impingement tendinitis help keep the joints flexible, while strengthening exercises help prevent impingement from occurring again, notes Sierra Pacific Orthopedics. Three sets of 20 repetitions of the internal rotation, external rotation and supraspinatus exercises help treat shoulder impingement, reports the Palo Alto Medical Foundation.
