Acupuncture, developed in China over 2500 years ago, is the insertion of fine, sterile needles into anatomically defined points on the body that stimulate the body's own healing mechanisms. Acu-points correspond to areas on the body that have been shown to have greater electrical conductance due to the presence of a higher density of gap junctions along cell borders1.
Current theories on the mechanism of acupuncture:
- Neurotransmitter Theory: Acupuncture affects higher brain areas, stimulating the secretion of beta-endorphins and enkephalins in the brain and spinal cord. The release of neurotransmitters influences the immune system and the antinociceptive system,2,3,4
- Autonomic Nervous System Theory: Acupuncture stimulates the release of norepinephrine, acetylcholine and several types of opioids, affecting changes in their turnover rate, normalizing the autonomic nervous system, and reducing pain.5,6
- Vascular-interstitial Theory: Acupuncture effects the electrical system of the body by creating or enhancing closed-circuit transport in tissues. This facilitates healing by allowing the transfer of material and electrical energy between normal and injured tissues.4
- Blood Chemistry Theory: Acupuncture affects the blood concentrations of triglycerides, cholesterol, and phospholipids, suggesting that acupuncture can both raise and diminish peripheral blood components, thereby regulating the body toward homeostasis.4
- Gate Control Theory: Acupuncture activates non-nociceptive receptors that inhibit the transmission of nociceptive signals in the dorsal horn, "gating out" painful stimuli.7
