Interventions focused on the scapula have been frequently used to treat shoulder pain. However, most studies do not assess the contribution of scapular movement alteration for the symptoms.

Objectives: To compare the effects of two interventions for shoulder pain: Scapular Movement Training and General Exercises.

This is a double-blinded randomized controlled trial. Sixty-four subjects with shoulder pain, scapular dyskinesis, and positive scapular assistance test will be randomized in two groups: 1) Scapular Movement Training, and 2) General Exercises. The Scapular Movement Training Group will receive the orientation about proper scapular position and movement, and will be trained to modify the scapular movement pattern. The General Exercises Group will perform scapulothoracic stretching and strengthening exercises.

Both groups will be treated twice a week for eight weeks. The following outcomes will be collected at baseline and follow-up: scapular kinematics, electromyographic muscle activity of the upper, middle and lower trapezius, and serratus anterior, as well as pain intensity, function, and fear avoidance beliefs. Also, pain intensity, function, and fear-avoidance beliefs will be assessed at the fourth week of follow-up after the end of treatment's period.
