Chuna That Doesn't Crack Your Joints — The Story of Thixotropic Chuna

When people hear "Chuna," many first picture the scene of "cracking the bones with a loud pop." But I don't do it that way.

The Chuna I practice is thixotropic Chuna. Instead of a sudden, forceful crack, it uses the property by which stiffened tissue softens on its own, slowly returning it to normal. In this article, I'll explain in plain terms what "thixotropy" is, and why this approach puts less strain on the body.

What is thixotropy?

Think of jelly or hardened honey. Left alone, it's firm, but if you stir it slowly, it softens. Then, when you leave it again, it hardens. This property of softening when given a steady stimulus is called thixotropy.

The fascia and connective tissue in our bodies have this property too. Even tissue that has been stiff for a long time gradually becomes supple when a sustained force is applied in the right direction. Thixotropic Chuna makes use of exactly this property.

How does it differ from "cracking Chuna"?

  • It uses sustained force instead of momentary force. Because there is no sudden crack, there is less tension and strain during the procedure.
  • It does not rely on the sound. The familiar "pop" is merely the sound of a gas bubble bursting inside the joint — it is not a sign that the adjustment worked well. Thixotropic Chuna is guided not by sound, but by the actual change of tissue becoming softer.
  • Because it restores alignment while the tissue is already released, the correction is not forced into place but happens in a direction the body accepts.

This is how pain and body structure are connected

Many pains arise not from a specific spot itself, but from the overall structure and posture of the body. When the pelvis is tilted, weight shifts to one side, and that strain spreads to the knees, ankles, and lower back. So I don't look only at the painful spot — I check the balance of the whole body structure together.

After releasing stiffened tissue with thixotropic Chuna and restoring the tilted alignment, I also guide you through postural habits and simple exercises so that the improved state is maintained. Correction is not something that ends in a single session; it includes the ongoing process of managing the body so it doesn't stiffen again.

I recommend this for the following people

  • Those who want correction but have been afraid of the strong, cracking approach
  • Those who have felt that they quickly return to their original state even after being adjusted
  • Those who feel their pain recurs because of posture or body structure

If you feel any discomfort during the procedure, please tell me at any time. I adjust the intensity and proceed only as much as your body accepts. Chuna therapy is covered by health insurance up to a certain number of sessions per year; I'll explain the details at your visit.

A graduate of the College of Korean Medicine at Kyung Hee University, with master's and doctoral degrees in pathology — the mechanisms of disease — from its graduate school. Later served as a research professor in the university's Herbology department, studying medicinal substances. Studying both disease and medicine from both sides is the foundation of this practice: explaining "why a given medicine works for a given illness" in the language of both pathology and pharmacology. Explains autonomic, chronic, and intractable conditions — and structural problems of the body — in the language of modern science, and proposes treatment matched to the cause. Has taught prescribing and clinical practice to Korean medicine doctors for over ten years, and is a co-author of "Korean Medicine, Explained by Korean Medicine Doctors," selected for the 2018 Sejong Books list (general category).
