Does The Type of Exercise Influence Outcome in Rotator Cuff Related Shoulder Pain

Participants from this group will be given a progressive shoulder strengthening exercises program based on 1 RM that will involve isometric, concentric and eccentric contractions. The exercises will target shoulder internal/external rotators and abductors and the scapular muscles. They will have to exercise every other day for 12 weeks. At each session with the therapist (6 over a 12 week period), strength will be reassessed and the program will be progressed accordingly. Any questions or concerns will also be addressed and participants will be requested to complete a paper based or digital record of their exercise participation.

Each session will start with a series of clinical tests that will look at the influence of different corrections to alleviate symptoms during upper limb movements.The tests will be performed in a sequential format through four key areas: thoracic repositioning, scapula facilitation, humeral head procedures and neuromodulatory techniques. If a correction reduces pain, that technique will then be performed as exercises and incorporated into the participant's functional movement. In addition, motor control exercises during arm elevation, progressed through a standardized 6-phase retraining sequence, will be executed. Retraining phases will be graded according to: 1) resistance applied on the shoulder; and 2) use or non-use of feedback. Once participants reach pain free execution, the program will be progressed into re-education exercises according to the participants' work, sport and activities of daily living and will incorporate activities involving the upper and lower limbs.

Each participant will be given written information about the shoulder (anatomy and function), basic pain science and will be directed to the Internet to watch a series of carefully selected educational videos. Comprehensive written advice will include: Information about the shoulder and the condition; Pain neuroscience; Activity modification (when to increase and decrease); Pain management (night and day); A series of educational videos to watch with 2 questions to answer per video: a) what was the most important message? and b) was there anything you didn't understand in the video?
