Do you locate ST25 (or SP15) in distance to umbilicus according to standard measurement criteria or according to the patient's thumb width (cun) ? |

The "official" way would be according to the classical CUN measurement as written in the classics. Actually however, the point is located parallel to the navel in the depression formed by the lateral margin of the rectus abdominis. |

Dr Halevi, Thanks for your information. I have not seen firm information about classical CUN measurement on abdomen (except between nipples and midline measurements). Would you please let me know dependable information about classical CUN measurement on abdomen in order to locate ST25 and SP15 accurately. |

Measurement of the abdomen is almost the same as the one given for the chest. The lateral line of the rectus abdominis is about 4 cun to each side of the navel. This line coincides approximately with the line stretching down from each nipple. Thus, 4 cun lateral to the navel is where Sp-15 can be located. Half way back to the navel (or 2 cun medially) is where St-25 can be found. Hope now it is clear. |

Dr Halevi, Sometimes exact locating of SP15 based on nipples in women (esp fat and old women) is difficult; lateral line of rectus is not clear too. How do you correctly locate it in such patients ? |

In this case you need to palpate the abdomen slightly with your fingertips laterally from the umbilicus. You do this until you arrive at the supposed area of the point (evaluating the distance according to your best judgment and experience). A slightly firmer pressure at this area will most often reveal the small indent on the abdominal wall where the point is located. You need to understand that point location is more often than not an art rather than science. |
