BACKGROUND The lower trapezius is an important muscle for normal arthrokinematics of the scapula. In the early stages of rehabilitation, it is generally accepted to perform exercises with the shoulder kept below 90° of elevation in order to minimize risk for shoulder impingement. Few exercises for the lower trapezius have been studied which maintain the shoulder below 90° of humeral elevation. OBJECTIVE To identify therapeutic exercises performed below 90° of humeral elevation that activate… CONTINUE READING
