Objectives

Narrative objectives1

This study aims to evaluate the effectiveness and adherence to a structured home-based exercise program for the prevention and treatment of pelvic floor dysfunction and low back pain among Brazilian postpartum women living in Japan. The study also seeks to identify barriers and challenges related to access to pelvic floor rehabilitation services that those women may face in Japan.

Assessment

Primary outcomes

Change in pelvic floor dysfunction symptoms will be assessed using the Pelvic Floor Distress Inventory-20 (PFDI-20) from baseline to 8 weeks after the start of the intervention period in both the intervention and control groups.

Key secondary outcomes

The following secondary outcomes will be assessed from baseline to 8 weeks after the start of the intervention period in both the intervention and control groups:
Pelvic Floor Impact Questionnaire-7 (PFIQ-7): to assess changes in pelvic floor-related quality of life; Oswestry Disability Index (ODI): to assess changes in low back pain-related disability; Numeric Pain Rating Scale (NPRS): to assess changes in pain intensity.

Exercise adherence will be assessed using a weekly adherence questionnaire throughout the 8-week intervention period among participants in the intervention group only.

Exploratory outcome:
In addition, potential barriers to accessing pelvic floor rehabilitation services among Brazilian postpartum women living in Japan will be explored using a self-developed questionnaire.
