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 "dry" needle, one without medication or injection, inserted through the skin into areas of the muscle.
