This study evaluate the effectiveness of adding neuromuscular exercises with tactile, visual and auditory feedback to a scapula-focused treatment, both emphasizing the periscapular muscles on improvement of disability in patients with subacromial pain syndrome compared to patients receiving only strengthening exercise protocol.
Evidence of the effectiveness conservative treatments in shoulder impingement are in favor the application of specific exercises for scapulothoracic muscles and rotator cuff on pain reduction and improvement of upper limb function, supervised or performed at home, and these same exercises associated with other therapies promote a greater reduction in pain and improvement in disability. Currently, the evidence of better methodological quality present in the literature13 points out that the performance of motor control exercises focused on the scapula associated with mobilization and stretching generate pain improvement and clinically relevant improvement of the function. The few studies in this area have great methodological diversity with significant limitations. The hypothesis is that patients with subacromial pain syndrome who will receive traditional exercise protocol with the addition of neuromuscular training will show less functional disability, a greater reduction in pain intensity, increase muscle strength and range of motion when compared to the patient group that will receive only the protocol without neuromuscular training, immediately after the intervention, four and eight weeks and four months after randomization and that these benefits are clinically relevant.
