Eccentric Exercises for Shoulder Pain

Patients will be randomly assigned to one of two groups using a random number generator. Group 1 will be provided with in-office instruction of standard of care eccentric exercises for rotator cuff tendinopathy. Group 2 will be provided with in-office instruction as well as a instructional exercise video source (DVD) to take home as a reminder on how to perform two specific standard of care eccentric exercises for rotator cuff tendinopathy. Each group will be given a card to track adherence to the standard of care eccentric exercise routine as measured only by the days that they accomplish their exercises. Study exercise diary will be collected after 12 weeks of treatment. Eccentric exercises are taught as part of standard of care for rotator cuff tendinopathy.
