Acupuncture is defined as the insertion of needles into the body for therapeutic purposes. Western Acupuncture can be performed in two different ways, targeting particular trigger points or soft tissue structures. If the practitioner finds a trigger point in the muscle they can insert the needle directly into the trigger point which releases the muscular spasm and associated tightness. Trigger points are also sometimes referred to as ‘knots' in the muscle that can refer pain to other areas of the body. Needling these trigger points can relieve the pain both locally and in the other areas.
