Heuristic exploration of how leg checking procedures may lead to inappropriate sacroiliac clinical interventions.
Several primary studies have shown that an anatomical short leg predicts anterior rotation of the ipsilateral ilium, whereas anatomical long leg predicts posterior rotation of the ilium on the long leg side. At the same time, in chiropractic and other manual therapy professions, it is widely believed that the leg check finding of a short leg is associated with posterior ilium rotation, and a long leg with anterior ilium rotation. The purpose of this commentary is to explore the consequences of this paradox for the manual therapy professions, insofar as leg checking procedures are commonly used to derive appropriate vectors for chiropractic manipulation/adjustive procedures.
