It is postulated that in pregnang women, the practice of PM can reduce the severity of birth injuries.~Our main objective was to determine the effectiveness of a PM program to reduce the incidence and degree of intrapartum perineal injuries as a way to reduce the incidence of female PFD.~Secondary objectives were:~Assess the role of a MP program on the systolic and diastolic blood pressure. Determine the effect of a MP program on body weight (BMI).~It is a parallel group clinical trial with an allocation ratio of 1:2.~All pregnant women will be informed about the nature of the clinical trial. There will be no differences in the pregnant´s follow-up because it will be performed by two same Pilates monitor with the same formation.~Once the pregnant women is assigned to an arm of the study, those assigned to the intervention group will be sent to the Pilates monitor to explain and initiate the exercise of MP program while the control group will be informed to maintain their usual monitoring of pregnancy.~In the initial visit, the type of physical activity will be evaluated by filling in the international physical activity questionnaire (IPAQ).
In this paper, it is postulates that in pregnant women, the practice of PM led by a qualified professional for a period of four weeks can reduce the incidence of pelvic floor dysfunction (PFD) by decreasing the number of birth injuries.
