Osteopathy: Art, Science & Philosophy Mind – Body – Spirit are a single unity OMT is Hands-On Medicine Structure and Function are reciprocally related: Localized visceral stimulation produces patterns of reflex response in spinal segments related with somatic structures (1,2) The body is a system who heals itself and capable of self regulation 1.- Beal, M.C.: “Viscerosomatic Reflexes: A Review.” Journal of the A.O.A.. 85, (12): 786-801, 1983. 2.-Louisa Burns, Viscero-Somatic and Somato-Visceral Spinal Reflexes.

ISSN 1443-8461 The facilitated segment: There is evidence of spontaneous electromyographic (EMG) activity and increased sympathetic output at spinal levels associated with clinically detected segmental dysfunctions (Denslow 1947 & Korr, 1958). A vertebral segment or spinal cord level exhibits a pool of related neurons that maintain a state of partial excitation; then less afferent stimulation is required to trigger the discharge of impulses.

Joint Dysfunction: Deafferentation • The loss of motor control in a joint it can become restricted or unstable. • The Joint Dysfunction can alter the mechanoreceptors Type I & II discharge and limit their role on the pain modulation, which results in an increased nociceptor feedback. • This has effects at the segmental level and the cortex. The manipulation could reverse these effects acting at GDR’s level. 1.- Terrett and Terret, “Referred Posterior Thoracic Pain,” Chiropr J of Australia 2002; 32: 44 2.- Seaman DR, Winterstein JF.

David Lopez Sánchez DC, PT 9 Osteopathy & Tensegrity: The Body as full integrated Unit The body is a unit…with a architectural network of omnidirectional viscoelastic forces and rigid components distributed an tied through a tensegrity system. Thus the cranium content could be affected by tensions transferred from the related structures through the connective and soft tissues. Under this model secondary stresses can be the result of the posture of the spine and any distant change of tension within the musculoskeletal system. Graham Scarr. Helical tensegrity as a structural mechanism in human anatomy. International Journal of Osteopathic Medicine. March 2011 (Vol. 14, Issue 1, Pages 24-32.
Dentate Ligament Theory: Cord Traction 10David Lopez Sánchez DC, PT The Dentate Ligament connect the spinal cord and brain stem with dura mater. Any misalignmet at level Occipito-Atlanto-Axial could be a factor of direct traction on the spinal cord. 1) J Neurol Neurosurg Psiquiatría v.47 (4); 04 1984 2) The Origins of the Grostic Procedures.

David Lopez Sánchez DC, PT 11 Dentate Ligament : Role in Mielopathy • In presence of a spondylotic bar, tensile forces acts over the spinal cord from the dentate ligament causing traction and neural tissue stress, this produces narrowing of small vessels and decreased local microcirculation, thus consequentelly mielopathy. David N Levine. Pathogenesis of cervical spondylotic myelopathy. Journal of Neurology, Neurosurgery, and Psychiatry 1997;62:334-340
Dentate Ligament Theory: Cord Traction 12David Lopez Sánchez DC, PT Journal of Clinical Neuroscience 19 (2012) 1150–1153 Dentate Ligament before & after a meningiom of spinal cord resection. The spinocerebellar tracts (proprioception) are located at the site of maximal mechanical irritation, their irritation may cause hypertonicity and spasticity in the muscles of the pelvic girdle and lower extremities

Osteopathic Cavitation: Joint Space Separation? 14David Lopez Sánchez DC, PT • The separation of the zygapophyseal joints after manipulation has been demonstrated with MRI. • The observed gapping increases significantly over a tension of 8 kgs., the facetary surfaces separates 4,7 mms with an audible cavitation.

The menisci of the lumbar zygapophysial joints. J. Anat. (1982) 135, 4, pp. 795-809 795. The cervical zygapophysial joints and their richly innervated meniscoids have been well documented as source of neck pain (1). The High-Field MR image sequence is best for the evaluation of the meniscoid anatomy and pathology (2). Meniscoids may become entrapped between the articular cartilages of the facet joints and OMT could release them. OMT: Entrapped Zygoapophysial Meniscoid

• Prolonged or repetitive activity of dorsal horn neurons caused by sustained noxious stimulation may subsequently produces central sensitization and may be involved in the generation of referred pain and hyperalgesia across multiple spinal segments (Mira M, 2007). • The systematic critical review of the literature confirms an hypoalgesic effect of spinal manipulative therapy (SMT) on experimentally induced pain provoked by pressure (Millan, 2012, Bronfort, 2010) David Lopez Sánchez DC, PT 17 1.- Mira Meeus & Jo Nijs.

The OMT could not been seen only as an useful technique to restore the segmental mobility. It can also intend to restore the vascular and neural and homeosthatic functions of the tissues according the age, gender, lifestyles, health and current somatic dysfunction of the patient.

David Lopez Sánchez DC, PT 19 Spinal Osteopathic Manipulative Therapy: Where are we now? Osteopathy is a system of diagnosis and treatment with a well differentiated philosophy that practice a “whole person” approach in healthcare (1). Osteopathy does not declare to treat diseases or illness, it optimizes patient health to stimulate self-regulating processes (repair, anti- inflammatory, immunity and defense mechanisms, homeosthasis) (2). 1.- Glossary of Osteopathic Terminology.
