Coupled Motion: Relationship to Joint Assessment

Abstract

For many decades the osteopathic profession has embraced the model of physiologic motion of the spine as outlined by Harrison Fryette in 1918. Indeed his Laws of Physiologic Motion are often used as a predictive model for the assessment of spinal lesions and subsequent application of therapy. However, there is now increasing research that questions the validity and applicability of these Laws. This is a literature review of recent research into coupled motion of the spine.
