Dry needling involves a thin filiform needle. The needle penetrates the skin and stimulates underlying myofascial trigger points and muscular and connective tissues. The needle allows a physical therapist to target tissues they are not able to reach with their hands.
Physical therapists wear gloves and personal protective equipment when dry needling. The used sterile needles are disposed of in a medical collector.
As part of their entry-level education, physical therapists are well educated in anatomy and treatment of the body. Physical therapists who perform dry needling obtain specific postgraduate education and training.
