Such were based on the standard of \"normopelvis\" in the polar coordinate system plus the external criteria, normal progress of labor, protraction and arrest disorders. Characteristics of the dystocia pelvis included an abnormal side wall of the small pelvis as well as an increased resistance of the muscles of the pelvic floor. The efficiency of the discrimination was greatest when those variables were adopted from each transection (78.3%). Arrest disorders could be clearly distinguished from the normal cases, however, cases of protraction disorder presented more difficulty as the distribution was wide between normal and the arrest disorder. Here, the pelvic floor muscles contribute significantly.
