Dry Needling by a Physical Therapist: What You Should Know. Dry needling is a technique physical therapists use (where allowed by state law) for the treatment of pain and movement impairments. The technique uses a âdryâ needle, one without medication or injection, inserted through the skin into areas of the muscle.
Dry needling is a broad term used to differentiate ânon injectionâ needling from the practice of âinjection needlingâ which involves a hollow bore hypodermic needle to deliver an agent such as saline, local anesthetic, and corticosteroid into the tissue.
