Trial summary

The goal of this clinical trial is to test the efficacy of the perineal massage in reducing the levator ani muscle (LAM) co-activation. This phenomenon is characterized by the LAM contraction rather than its relaxation during the Valsalva maneuver and it is associated with adverse obstetric outcome. Read more about this study

About this study

Official title: Does Perineal Massage in Pregnancy Reduce the Levator Ani Muscle Co-activation?

The goal of this clinical trial is to test the efficacy of the perineal massage in reducing the levator ani muscle (LAM) co-activation. This phenomenon is characterized by the LAM contraction rather than its relaxation during the Valsalva maneuver and it is associated with adverse obstetric outcome. Participants who co-activate will be enrolled and randomized in 2 groups: group A, where women themselves perform the perineal massage during the third trimester of pregnancy and group B, where women undergo the standard care. Researchers will compare these groups to see if the perineal massage is able to reduce LAM co-activation.

Read the detailed description

The levator ani muscle has to relax instead of contracting during the pushing efforts in childbirth. However, some women consciously or unconsciously co-contract, or tighten, the levator ani muscle. This phenomenon is levator ani muscle co-activation. Recently, it has been shown that co-activation may be associated with unfavorable obstetric outcomes, such as prolonged second stages of labor and higher fetal head station in women with co-contraction.

Recently, a study assessing the correlation between levator ani muscle co-activation and perineal trauma has been published. This study found a significantly higher incidence of severe perineal trauma related to childbirth (i.e., third and fourth-degree lacerations and episiotomies) in women with levator ani muscle co-activation. This group of patients had approximately three times the risk of a vacuum-assisted vaginal delivery and five times the risk of developing a severe vagino-perineal laceration with potential involvement of the anal sphincter. Therefore, intervening in these patients with targeted measures to correct LAM co-activation in the third trimester of pregnancy might be promising.

Study design All women are informed about this study during the first trimester of pregnancy. During the anatomical scan, at 20-22 gestational weeks, women are screened for eligibility criteria, including: nulliparity, single pregnancy, fetus in cephalic presentation and fluency in Italian language. Women satisfying the inclusion criteria are asked to participate to this RCT. If women agree to participate in the study, an informed consent will be signed. Thereafter, a trans-perineal ultrasound will be performed in order to evaluate the presence of levator ani muscle co-activation. A medio-sagittal scan is obtained to identify the following landmarks: pubic symphysis, fetal head, rectum, and puborectal muscle. In this scan, the antero-posterior diameter of the anorectal angle (APD) is measured, which is the minimum distance between the postero-inferior border of the pubic symphysis and the anterior border of the puborectal muscle. This measurement is taken both at rest and during maternal pushing (Valsalva maneuver). Patients with co-activation will be identified by an APD during Valsalva that is smaller than the one observed at rest. Patients will be enrolled and randomized only in case of LAM co-activation.

A 1:1 randomization will be done using a specific function of Excel (preliminarily prepared by our Statistician). Women will be randomized in 2 arms: arm A is represented by the treatment "perineal massage", while arm B is represented by the "standard care".

At about 30 gestational weeks women randomized to arm A will be trained on how technically perform the perineal massage. Participants are instructed to do the perineal massage once daily from 34 gestational weeks until delivery, for at least 3 weeks continuously. By contrast, women randomized to arm B are informed on currently available recommendations to take care for pelvic floor in pregnancy. These recommendations include advices on healthy diet, physical activity and voiding training.

At 37-38 gestational weeks all randomized women are scanned again in order to measure the APD at rest and under Valsalva. All anthropometric and clinical data are collected and anonymized.

Intra-partum part of the study This part of the project involves data collection on labor, delivery, and neonatal outcomes. The labor and delivery care-providers operate blindly with respect to the antepartum ultrasound measurements.

The study was powered based on the primary endpoint, which is the 40% reduction in LAM co-activation at term after perineal massage therapy. It is necessary to randomize 58 subjects (29 women per group).

The primary outcome of this trial is to assess whether the intervention "perineal massage", compared to the standard care, is able to significantly reduce the levator ani co-activation. Secondary outcomes are the standardization of the perineal massage and the comparison of perineal trauma prevalence between the 2 arms.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • perineal massageBehavioural

    women affected by LAM co-activation allocated to the intervention "perineal massage" are asked to perform the perineal massage once daily from 34 gestational weeks until delivery. Women are trained to correctly perform the perineal massage at 30 gestaitonal weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comparison of the percentages of women without levator ani muscle co-activation after treatment or after standard care, evaluated at 37-38 weeks of gestation, using chi square test.

    All women who consent to participate in the study will be scanned through a trans-perineal ultrasound at 20 weeks. Co-activation is defined when the levator ani muscle antero-posterior diameter under Valsalva manueuver is lower than the same diameter measured at rest, with trans-perineal ultrasound.

    In case of LAM co-activation women will be recruited and randomized into two groups: the perineal massage group vs the standard care group. All randomized women will be evaluated with trans-perineal ultrasound for the levator ani muscle antero-posterior diameter measurement at 37-38 gestational weeks.

    To evaluate the effectiveness of the perineal massage, the percentages of women without LAM co-activation after treatment or after standard care, evaluated at 37-38 weeks, will be compared. For the comparison a chi square test will be used.

    Measured: at 20 gestational weeks and at 37-40 gestational weeks

Secondary outcomes (2)
  1. Evaluation of significant differences in spontaneous or iatrogenic vaginal tears between the groups

    The comparisons between groups will occur through chi-square tests for categorical variables and Student's t-tests for continuous variables.

    Vaginal tears are classified into first- degree, second- degree vaginal laceration, obstetric anal sphincter injury (OASI) and episiotomy

    Measured: immediately after fetus delivery

  2. percentage of women who completely adhere to perineal massage, i.e. who perform the perineal massage once a day, at least 5 days a week, from 34 gestational weeks until delivery.

    for the effectiveness of perineal massage, participants in the "perineal massage" arm should perform the massage once a day, at least 5 days a week, from 34 gestational weeks until delivery. Participants will be asked to complete a diary, noting the days on which they perform the perineal massage.

    Measured: from 34 gestational weeks until the moment of delivery (between 37 weeks and 41 weeks and 3 days of gestation).
