Normal muscle length and function is then restored by releasing this tension. Relaxation occurs either by stimulation of the MTrP in which a local twitch response occurs resulting in deactivation of that MTrP, or by causing a localized stretch of the tight muscle fibers. How Does Trigger Point Dry Needling Work?įilament needles are inserted into a specific area of a tight muscle causing it to relax. By releasing the trigger points, the referral pain is thereby eliminated. There have been several research studies and case reports that have documented referred pain patterns from MTrPs. The pain produced by MTrPs can be localized to the area of tightness, but can also be referred or felt in a different area of the body. These tight bands of muscle can restrict blood flow and nerve conduction which propagates this cycle of dysfunction. This build up of ACh results in a localized, involuntary contraction of muscle tissue that can cause muscle weakness and limited range of motion in addition to pain. MTrPs are thought to be caused by the nerves that control the muscles releasing an excessive amount of a chemical called acetylcholine (ACh). David Simons define MTrPs as “hyperirritable spots in skeletal muscle that are associated with a hypersensitive palpable nodule in a taut band”. Myofascial trigger points (MTrP) are seen in both acute and chronic conditions and collectively referred to as Myofascial Pain Syndrome. What Can Trigger Point Dry Needling Help?ĭry needling is a cost effective and efficient technique that has been shown to help alleviate the symptoms associated with the following conditions: This technique differs from acupuncture in that it is based on Western medicine principles and not Traditional Chinese Medicine (Travell and Simons 1999). It is inserted into the muscle to help release trigger points and relieve pain. Trigger Point Dry needling involves using a filament needle, like those used in acupuncture, to treat myofascial pain and dysfunction.
