Trigger Point Dry Needling A trigger point is a “knot" in the muscle tissue that may be tender to the touch. A trigger point may also cause “referred pain," or pain which is distant from the trigger point. For example, a muscle in the hip can cause pain all the way down the leg, and may be mistaken for “sciatic" pain. Trigger points have what is called ‘spontaneous electrical activity’ (SEA) which causes an increase in chemical activity and a build-up of lactic acid.
With trigger point dry needling, the physical therapist uses a needle, similar to an acupuncture needle, and inserts it into the skin and muscle directly at the trigger point. The needle causes an electrical and chemical effect. When the needle is inserted into the trigger point, the muscle may twitch allowing the contracted muscle fibers to relax, eliminating the spontaneous electrical activity, and allowing the acidity in the area return to normal and blood flow to return back to the area. This relieves pain, improves mobility and muscle function, and allows for tissue healing. At All-Pro Health, the physical therapist will treat trigger points as part of a complete therapy program in conjunction with other manual techniques and corrective exercise.
