Using the posterior pelvic pain provocation test in pregnant Japanese women

This study investigated the usefulness of the posterior pelvic pain provocation (PPPP) test for differentiating between pelvic pain and low back pain because of the different prognoses and treatment strategies. We recruited 263 Japanese women who were > 36 weeks' gestation and 213 were included. The PPPP test was applied to 154 women with self-reported lumbopelvic pain. The participants were divided into three groups: the PPPP test positive (PPPP+, n = 60) subgroup, PPPP test negative (PPPP-, n = 94) subgroup, and no pain group (n = 59). The disability scores of the PPPP+ subgroup were significantly higher than the scores of the PPPP- subgroup and no pain group. In the PPPP+ subgroup, the intensity of pelvic pain was significantly correlated with the disability scores, but that of low back pain was not. The PPPP test could be carried out by a midwife without side-effects and could detect pregnant women with impaired ability in daily life due to lumbopelvic pain.
