Magnetic resonance imaging study of safe needling depth and angulation for acupuncture at BL40.

Published in: Acupuncture in medicine : journal of the British Medical Acupuncture Society (2020)

We would suggest that, when using a straight needle insertion at BL40, it is safe to advance a 25-mm needle approximately 12.5 mm, and 17.5 mm should be safe for patients with BMI greater than 28 kg/m2. Practitioners should decrease the depth of penetration when treating patients of low body weight or height.
