Trigger point dry needling is a technique to treat myofascial pain and trigger points in the muscles. It involves the use of a solid, sterile needle inserted through the skin into the muscle trigger point, or where the patient reports a “knot” in the muscle. The goal of dry needling is to release or inactivate the trigger points to relieve pain, reduce muscle tension, improve range of motion, and normalize muscle dysfunction. This can often speed up the patient’s return to active rehabilitation and function.
