Both techniques utilize the same thin needles. IMS is based on the work of Chan Gunn, MD who developed a system of needling treatment based on the findings of neuropathic changes in the musculoskeletal system. Needling the tight painful band of muscle releases tension, this in turn allows increased mobility. Acupuncture is thought to stimulate the nervous system to release chemicals in the muscles, spinal cord, and brain. These chemicals will either change the experience of pain, or they will trigger the release of other chemicals and hormones that influence the internal regulating system of the body.
