A functional model of musculoskeletal disorders states that biomechanical disturbances are a manifestation of the intrinsic properties of the tissues affected. The body’s ability to adapt to physiological stresses is demonstrated as loss of joint mobility, loss of tissue resiliency and gross changes in motion or postural symmetry. These physiological adaptations are collectively described as Somatic Dysfunction. Tissue restrictions in one area of the body can have a profound impact on other areas of the body. Effective musculoskeletal therapy should incorporate this concept with a sound understanding of the physiology and pathophysiology of somatic tissues.
