Résumé : Aim. To perform an instrumental study (tonimetric test) of the pelvic floor contractility (element that we consider may be necessary for the maintenance of its normal physiological functions) and its correlation with different parameters. Material and method. To fill out a questionnaire together with a gynecological examination that includes a perineal tonimetric test in order to collect the study variables. Statistical comparison of muscular strength in two similar patient groups, with the only difference that one of them is composed of women in immediate postpartum period. In addition, a correlation was performed between this parameter and some different variables such as body mass index (BMI), sports activity and several gynecological factors. Results. Mean muscular strength in both patient groups is similar and above the mean reference. Nevertheless, it is not high enough to achieve correct perineal blockage with stress (especially among patients in immediate postpartum period). There is no correlation between any of the variables studied and pelvic floor muscular strength in either of the patient groups. Conclusions. Partum and strength of contraction of pelvic floor are not related in any case and must be considered as totally independent variables. This fact, together with the impossibility for the majority of the population (even for young and asymptomatic individuals) to perform correct perineal blockage, has led us to conclude that there is no reason to use the so extended practice of pelvic floor re-education as a priority treatment or exclusive one for muscular strength enhancement during the postpartum period.
