Impingement Syndrome and Impingement-Related Instability

Impingement syndrome historically has been considered to be a continuum of a single pathologic condition involving the subacromial soft tissue.As our understanding of this complex problem has developed, the simple continuum model has become less effective in guiding appropriate treatment. The purpose of this lesson is to provide the reader with more precise classifications of impingement syndrome and the impingement stability complex and their associated impairments, to provide more efficient and effective interventions that address the primary abnormality.
