Location & How to Find

Anatomical Location: Palmar aspect of fingers 2-5, at the PIP joint crease.

Extra points have no international location standard, and Chinese texts number and place some of them differently. This location follows common teaching.

How to Locate:

  1. Look at the palm side of fingers 2, 3, 4, and 5 (not the thumb)
  2. Find the middle joint crease on each finger
  3. Locate the center point of each crease on the palm side
  4. These four crease points are EXT-28
