産後の回復のための治療的運動 (PelviRecover)
産後回復における腰盤安定化運動と低圧運動の比較：無作為化臨床試験
Pelvic floor dysfunctions (PFDs) are common conditions that affect women, especially after vaginal childbirth. These disorders can cause urinary or fecal incontinence, pain during sexual activity, and prolapse of pelvic organs, leading to a significant decrease in quality of life. Current scientific evidence shows that early and specific physiotherapy-based interventions after childbirth may help reduce the risk of developing long-term PFDs.
Pelvic floor muscle training (PFMT) is currently the first-line conservative treatment for women with PFD, but in recent years other exercise methods, such as hypopressive exercises, have become increasingly popular, despite limited supporting evidence. At the same time, some women need to return early to physically demanding jobs or impact sports, but there are no clear guidelines on how to safely prepare the abdominopelvic region for progressive exposure to increased intra-abdominal pressure.
This study aims to compare two postpartum recovery exercise programs:
A program based on lumbopelvic stabilization exercises that progressively expose women to increases in intra-abdominal pressure and impact activities.
A program based on hypopressive exercises, which focus on avoiding intra-abdominal pressure.
The goal is to determine which approach is safer and more effective in improving pelvic floor recovery after childbirth and in supporting women in their gradual return to daily, work, and sports activities.
調査の概要

詳細な説明
Pelvic floor dysfunctions (PFDs) are highly prevalent conditions that impose a substantial burden on women's health, particularly following vaginal childbirth. Vaginal delivery has been identified as a major risk factor due to potential trauma to the pelvic floor, including overstretching of muscles and nerves, damage to connective tissue supporting pelvic organs, and direct perineal injury. Obstetric interventions such as forceps or vacuum-assisted delivery, episiotomy, and epidural anesthesia may further exacerbate the risk of PFDs. Longitudinal studies indicate that a considerable proportion of women continue to experience urinary or fecal incontinence, dyspareunia, or prolapse for many years after childbirth, highlighting the chronic nature of these dysfunctions and the need for preventive strategies.
Physiotherapy-based interventions have demonstrated promise in reducing the incidence and severity of PFDs when applied early in the postpartum period. Pelvic floor muscle training (PFMT) is considered the gold standard conservative therapy, supported by randomized controlled trials and systematic reviews. PFMT effectively improves muscle strength and function, and its use is endorsed by international guidelines, such as those from the National Institute for Health and Care Excellence (NICE).
In recent years, hypopressive exercises (HE) have been promoted as an alternative or complementary approach to PFMT. HE were originally developed to restore abdominal wall function without provoking increases in intra-abdominal pressure, which is considered a risk factor for pelvic floor overload. Preliminary studies suggest potential benefits in muscle activation and patient satisfaction, yet the quality of evidence remains low, with most research limited to observational designs, small sample sizes, and short follow-up periods. Therefore, the effectiveness and safety of HE in postpartum populations remain uncertain.
Parallel to this, lumbopelvic stabilization exercises (LSE) have been proposed as a means to strengthen the transversus abdominis, multifidus, and pelvic floor muscles through a staged protocol beginning with isometric and coordinated contractions and progressing to integrated functional tasks. Importantly, LSE involve gradual exposure to increased intra-abdominal pressure and impact-related forces, which may facilitate safer return to occupational or athletic activities requiring lifting or high-impact loading. While these exercises have shown benefit in postpartum lumbopelvic pain, there is insufficient evidence on their role in pelvic floor recovery.
Given the growing number of women who resume physically demanding work or impact sports shortly after childbirth, the absence of clear, evidence-based guidelines for abdominopelvic conditioning represents a significant gap in postpartum care. The International Continence Society (ICS) has described PFDs as a "silent epidemic," underlining the urgent need for preventive and rehabilitative interventions supported by rigorous clinical trials.
The present randomized controlled trial is designed to address this gap by directly comparing two structured postpartum rehabilitation approaches: (1) a program of lumbopelvic stabilization exercises incorporating progressive exposure to intra-abdominal pressure and impact, and (2) a program of hypopressive exercises aimed at minimizing intra-abdominal pressure.
This study is expected to generate high-quality evidence regarding the comparative safety and efficacy of these two exercise-based strategies. The findings will provide valuable guidance for clinicians, physiotherapists, and policymakers, contributing to the development of standardized postpartum rehabilitation protocols. Ultimately, the trial seeks to improve long-term pelvic health outcomes and support women in safely returning to their daily, occupational, and athletic activities after childbirth.
