Acupuncture is a modern, science-based intervention for the treatment of pain and dysfunction in muscles, tendons and ligaments. Scientific research has illuminated the principal mechanisms by which acupuncture (also called dry needling) works. The insertion of needles into muscles stimulates an increased blood flow, oxygen and nutrients to the muscles. This releases the myofascial trigger points, decreasing your pain and improving functioning.Acupuncture is a form of therapy in which fine needles are inserted into myofascial trigger points (muscular knots), tendons, ligaments, or nerves in order to stimulate a healing response in painful musculoskeletal conditions.
