RESUMO
INTRODUCTION AND HYPOTHESIS: The relationship between external lumbar, hip, and/or pelvic girdle pain and internal vaginal pelvic floor myofascial pain is not well described. We assessed this relationship in a cohort of adult women. METHODS: The cohort included women ≥ 18 years old who received care for external lumbar, hip, and/or pelvic girdle pain (reported or elicited on physical examination) who then underwent internal vaginal myofascial levator ani pain assessments, in a tertiary care Female Pelvic Medicine and Reconstructive Surgery pelvic pain clinic over a 2-year period (2013 and 2014). RESULTS: The cohort of 177 women had an average age of 44.9±16.0 years, an average body mass index of 27.2±7.0 kg/m2, and the majority (79.2%) were white. Most patients presented with a chief complaint of pelvic (51.4%), vulvovaginal (18.6%), and/or lumbar (15.3%) pain. Women who reported symptoms of lumbar, hip, or pelvic girdle pain were more likely to have pain on vaginal pelvic floor muscle examination than women without this history (OR, 7.24; 95% CI, 1.95-26.93, p=0.003). The majority (85.9%) of women had bilateral internal vaginal pelvic floor myofascial pain on examination. CONCLUSIONS: Although participants did not describe "vaginal pelvic floor myofascial pain," the high detection rate for internal vaginal pelvic floor myofascial pain on clinical examination highlights an opportunity to improve treatment planning. These findings suggest that the vaginal pelvic floor muscle examination should be part of the assessment of all women with lumbar, hip, and/or pelvic girdle pain. The relationship between this finding and clinical outcomes following directed treatment warrants additional study.
