There is a lack of clinical trials in the literature that evaluated the effectiveness of neuromuscular control focused on periscapular muscles. The few studies in this area have great methodological diversity with significant limitations. The hypothesis is that patients with shoulder impingement 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.
