Transcultural adaptation and psychometric validation of a Spanish-language version of the "Pelvic Girdle Questionnaire".

BACKGROUND: The Pelvic Girdle Questionnaire is the only instrument designed to assess pain and disability specifically in pregnant or postpartum women with pelvic girdle pain. The objective of this study was the adaptation to the Spanish language and analysis of the psychometric properties of the Pelvic Girdle Questionnaire. METHODS: This is a descriptive cross-sectional study divided into two phases. In the first phase, a translation and adaptation process was performed according to international guidelines. Secondly, the analysis of the properties of the Spanish version was conducted using a sample of 125 pregnant or postpartum women suffering from pelvic girdle pain. Participants completed the Spanish version along with five other measurement instruments through an online platform. Internal consistency, construct validity, test-retest reliability, the ceiling and floor effects, responsiveness and discriminatory ability of the Spanish version were analysed. RESULTS: The Spanish version of the Pelvic Girdle Questionnaire showed high internal consistency with Cronbach's alpha = 0.961, and an intraclass correlation coefficient of 0.962. The convergent validity showed high positive correlation with other questionnaires used. ROC curves showed no discriminatory capacity for number of sites of pain or pregnancy/post-partum state. CONCLUSIONS: This article presents the translation, validation and psychometric properties of the Spanish version of the Pelvic Girdle Questionnaire, that has proved to be an appropriate and valid assessment tool of disability due to pelvic girdle pain in pregnant and postpartum women.

Diastasis of symphysis pubis and labor: Systematic review.

Symphysis pubis diastasis (SPD) is an infrequent complication of labor that can impair womens' general health through failure of the passive stability of the pelvic girdle. Although conservative approaches are often used to decrease symptoms and interpubic separation, notably few studies have analyzed the effect of these methods on managing the symptoms of women with SPD. The purpose of this study was to review the available literature on the conservative treatment of SPD during pregnancy and labor. A computer-based search using PubMed, PEDro, and CINAHL was performed up to November 2014. We selected all studies that considered women with SPD during pregnancy or labor and treated them with conservative methods and excluded those that included surgical intervention. Eighteen studies were selected, most of which were case reports. Although the overall results of conservative treatment were unclear because of the type and design of the obtained studies, most of the studies reported bed rest in the lateral decubitus position and a pelvic girdle as basic treatments. Additionally, the few clinical trials reported recommended additional physiotherapy, including strengthening and stabilizing exercises, to reduce SPD symptoms.
