Wrist-ankle acupuncture divides the body into six longitudinal zones and treats them at points just above the wrist and ankle, using shallow subcutaneous insertion. Abdominal acupuncture maps the abdomen onto the whole body and uses a small set of points there for systemic and musculoskeletal conditions. Floating needling inserts a needle into the subcutaneous layer near a painful area and moves it horizontally to release fascial restriction.
All three depart from classical point theory and each has developed its own training and evidence base. They illustrate a continuing pattern in acupuncture history: new mapping systems are proposed, tested in practice, and either absorbed or set aside.
