An Extension Vertebral Dysfunction
Purpose: Illustrate the mechanics of somatic dysfunction if a facet, in this case the right inferior facet of the top vertebra, (the one closest to the camera) becomes restricted in extension. The position is “normal” i.e. not palpable in extension but becomes obvious, and easily palpable, in flexion. Explains why the naming convention of the dysfunction seems to be the reverse of the findings, e.g. if you find it in flexion it is an extension dysfunction.
