Shoulder dysfunction is commonplace in training, particularly for overhead movement. While the structural diagnosis may vary: tendonitis, bursitis, subacromial impingement, sprains, strains, tears, dislocations, subluxations; the functional diagnosis is usually quite similar. The functional diagnosis is the reason or cause for the pain. In other words, the dysfunction or compensation that has inevitably led to the tissue injury, the structural diagnosis. But the reverse is also true. The functional diagnosis can be the dysfunction or compensation that occurs secondary to protection and inhibition due to the injury.
