Pressure Point: BL 33 – Zhongliao
- Name (Chinese): Zhongliao – (中髎)
- Name (English): Middle Bone Hole
- Introduction: Zhongliao (BL-33) is a pressure point associated with the Bladder meridian in traditional Chinese medicine. It is located in the 3rd posterior sacral foramen.
Location
In the 3rd posterior sacral foramen, between the posterior superior iliac spine and the midline.
Pressure Point Identification
- First, identify Tuffier’s line, connecting the highest points of the iliac crest, with the spinous process of the 4th lumbar vertebra (L4) mostly falling on this line.
- Palpate in an inferior direction, passing L5, until reaching the most superior 1st sacral foramen. Continue palpating to reach the 3rd foramen, where Zhongliao BL-33 is located.
- To identify all 4 sacral foramina, locate the 4th foramen on the level of the superior end of the rima ani. Place fingers as follows: little finger on the 4th foramen, ring, middle, and index fingers on a slightly V-shaped line in a superior direction, palpating for the depressions of the sacral foramina.
- With fingers in this position, the index finger rests on Shangliao BL-31 of the 1st foramen, the middle finger on Ciliao BL-32 of the 2nd foramen, the ring finger on Zhongliao BL 33 of the 3rd foramen, and the little finger on Xialiao BL-34 of the 4th foramen.
