Chiropractic Antistress Mechanism

  1. 1. At a Glance: Understanding the Anti-Stress Mechanism of Chiropractic Andrew S. Bonci, DC, DAAPM, BCETS, FAAETS Chairman, Department of Diagnostic Sciences Cleveland Chiropractic College, Kansas City Step 1: Step 2: Step 3: Mechanical Stimulation Oxytocin Secretion Parasympathetic Up-Regulation Step 1: Non-noxious mechanical stimulation, light touch and massage of the type commonly employed in chiropractic therapies results in neuronal activation of the supraoptic nuclei of the hypothalamus. This provokes system wide alterations in both biological and psychological function. Step 2: Once stimulated, these nerves of the supraoptic nuclei release oxytocin in a manner similar to that seen during the "suckling reflex." Oxytocin exerts a profound upregulating effect on the parasympathetic nervous system. Step 3: This provoked release of oxytocin has been shown to be anxiolytic, antihypertensive, antinociceptive, and antidepressive. It has also been shown to induce feeding behaviors, enhance social behaviors and reduce hyperactivity. Thus, mechanical stimulation of the musculoskeletal tissues and the integument can exert anti-stress benefits. References Kurosawa M, et al.
