COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
Group 1 (Control): Perform standardized pelvic floor exercises (PFMT),
designed by the physiotherapy team that will participate in the study, following the
current clinical practice guidelines and determining a duration of at least 12
weeks for the completion of the exercises.
Group 2 (Intervention-a): Perform the pelvic floor exercises established by the
physiotherapy equipment while using the vaginal spheres. The duration of it
They will also be 12 weeks.
Group 3 (Intervention-b): they will use the vaginal spheres in their life activities
daily during the 12 weeks of the intervention and intensively, according to the
program determined by the physiotherapy team that will participate in the study.

- material used: Group 2 and 3 will use one vaginal ball (24gr) during the intervention
- procedures/activities/exercices: Pelvic floor Muscle training (PFMT) exercices,
designed by the physiotherapy team
- who will deliver the intervention: the midwifes and the physiotherapist in charge of the program
- the mode of delivery: group 1 and 2 will assist to one class per week and subsequently will apply the new exercises learned in the class, at home during the next week.
- frequency: group 1 and 2 will do twice a day exercises at home (10 minutes in the morning + 10 minutes in the afternoon) Group 3 will do their daily life activities with the vaginal balls during 20 minutes per day (preferably in the mornings)
- We will use whatsapp groups to monitor the adherence to the treatment.

Comparator / control treatment

• Group 1 (Control) = PFMT would perform the exercises exclusively designed by the team of Physiotherapy participating in the study.

• Group 2 (Intervention-a) = PFMT would perform exercises with the use of vaginal spheres.

• Group 3 (Intervention-b) = would perform intensive treatment, designed for physiotherapy equipment vaginal areas.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The study will be a Controlled and Randomized Clinical Trial, single-blind (Technical
opaque envelopes), with three parallel groups for intervention and subsequent
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (GP.Power programme in version In which we will apply an effect size of 0.8, comparing in parallel the three focus groups.

Statistical methods / analysis
After a scan statistic of the data input to detect errors in the base, the same will be
described as the three study groups. Quantitative variables are expressed in means
and standard or medians and 25th and 75th percentiles, if skewed distributions
deviations, and qualitative variables with frequency and percentage.
Next, an analysis of baseline comparability between the two groups will be performed.
for analyse the relationships between qualitative variables, contingency tables will be
made and the Chi-square test or non-asymptotic test methods and Monte Carlo exact
test will be applied.
To see if there are differences in average of numerical variables between the two
groups, T-Student's test will be used for independent samples or Mann-Whitney-U
Test for non-normal distributions. Significant mean differences will be quantified with
confidence intervals at 95% and, if not normal, the differences between medians with
confidence intervals Hodges-Lehman 95%.
Furthermore, to contrast changes in a numerical parameter measured at different time
points (possible intra-intervention assessments) within each group, the Friedman Test
or the nonparametric Wilcoxon Test is applied in the case of only two moments. The
change between two time points of a qualitative variable is analysed with the
McNemar Test.
The data analysis will be performed with the statistical program SPSS 23.0 for

Brief summary
- In order to determine the effectiveness of using vaginal areas for improving the
perineal strength of women in the postpartum period, we have designed a randomized
experimental clinical trial. We will take as a reference population all primiparous
women who give birth in the metropolitan area of Seville, in the course of a year.

- To determine the effectiveness of 3 types of muscle training for recovery pelvic floor
postpartum and evaluate their effectiveness by perineometer, Test and Modified
Oxford ICIQ Incontinence Questionnaire SF.

- Therefore, women in the puerperal period, perform pelvic floor exercises (PFMT) with
vaginal spheres, have more rapid and effective recovery of the perineal strength .
