What is Dry Needling?
Dry needling is a technique physical therapists and athletic trainers use (where allowed by state law) for the treatment of pain and movement impairments. The technique uses a “dry” needle, one without medication or injection, inserted through the skin into areas of the muscle. Other terms commonly used to describe dry needling, include trigger point dry needling, and intramuscular manual therapy.
Dry needling is not acupuncture, a practice based on traditional Chinese medicine and performed by acupuncturists. Dry needling is a part of modern Western medicine principles, and supported by research.
What Is A Trigger Point?
A trigger point is a taut band of skeletal muscle located within a larger muscle group. Trigger points can be tender to the touch, and touching a trigger point may cause pain to other parts of the body.
What Kind Of Needles Are Used?
Dry needling involves a thin filiform needle that penetrates the skin and stimulates underlying myofascial trigger points and muscular and connective tissues. The needle allows the clinician to target tissues that are not manually palpable.
Clinicians wear gloves and appropriate personal protective equipment (PPE) when dry needling, consistent with Standard Precautions, Guide to Infection Prevention for Outpatient Settings, and OSHA standards. The sterile needles are disposed of in a medical sharps container.
Why Dry Needling?
Dry needling is often used with the goal of releasing or inactivating trigger points to relieve pain or improve range of motion. In cases when dry needling is used by physical therapists and athletic trainers, it is typically one technique that is part of a larger treatment plan. Preliminary research supports that dry needling improves pain control, reduces muscle tension, and normalizes dysfunctions of the motor end plates, the sites at which nerve impulses are transmitted to muscles. This type of treatment can help speed up the patient’s return to active rehabilitation.
