Watch the video and follow along. JCVD's split is not so perfect.
Using the Principles of Diagnostic Motion Evaluation, Here are the dysfunctions that I found:
1. At the very beginning of the video you will notice that his Right foot is externally rotated. We do not know if this is a Structural or a Non-structural Dysfunction.
If you do not know the difference between a Structural and Non-Structural Dysfunction, click here.
2. When the trucks are moving you will notice non-sequential movement in his Left mid thigh and compensatory movement in his pelvis.
This is a Structural Dysfunction because the movement of the trucks is causing Passive Range of Motion.
The exact location of this Dysfunction is in middle of his left thigh.
The motion is in the Open Chain. Although his feet are on the ground the definition of an Open Chain motion is when the Distal Structures (his legs) move about a stationary Proximal structure. (his pelvis and trunk)
To treat JCVD, you would palpate along the middle Left thigh cumferetially for a restriction in the Connective Tissue and release it using a treatment for restrictive tissues; such as mobilization or massage.
Once treated Jean Claude would have his perfect split.
If this make no sense to you then please check out my video on Diagnostic Motion Evaluation. Using this technique literally changed my career.
Just yesterday I achieve 15 degrees of motion in a knee patient by mobilizing her ankle and lower leg.
