Rehabilitation of Abdominal Diastasis After Childbirth: Trunk and Inspiratory Muscle Training

Summary

Diastasis Recti Abdominis (DRA) is the separation of the rectus muscles caused by stretching and thinning of the linea alba during pregnancy and childbirth. It's a common condition, affecting 66-100% of women post-birth and can persist for many years, leading to abdominal protrusion, discomfort, and aesthetic concerns. It might also contribute to back pain, urinary issues, and reduced abdominal strength, impacting quality of life. Recent guidelines propose that conservative management, such as rehabilitation interventions, should be prioritized for DRA. However, there is a lack of consensus among researchers regarding the most effective exercise regimen, resulting in diverse rehabilitation programs. Recent evidence advocates not only for closing the gap but also for achieving optimal function. Current studies often neglect to address functional rehabilitation, underscoring the necessity for robust clinical trials, which is the primary focus of this study.

Additionally, although breathing exercises are commonly prescribed for DRA, the precise role of the diaphragm, the primary respiratory muscle, in rehabilitation hasn't been fully examined. The diaphragm forms the upper boundary of the abdominal cavity and plays a key role in the stability of the trunk, working together with the abdominal and pelvic floor muscles. A recent study found reduced diaphragm excursion in postpartum women with lumbopelvic pain during a low postural demanding task, while previous studies suggest that diaphragm training could alleviate such symptoms influencing factors such as diaphragm thickness and excursion, which may be linked to improved trunk stability. Hence, training the diaphragm and accessory inspiratory muscles through Inspiratory Muscle Training (IMT) could potentially play a crucial role in managing DRA.

In summary, the goal of this study is to develop and assess a comprehensive rehabilitation program aimed at effectively reducing DRA and addressing associated dysfunctions. The program will integrate evidence-based rehabilitation interventions, such as trunk stabilization exercises and IMT, targeting all related dysfunctions caused by DRA, and introducing a novel therapeutic protocol not previously implemented. The study will take the form of a prospective, randomized controlled trial (RCT).

Conditions

• Diastasis Recti And Weakness Of The Linea Alba
• Diastasis, Muscle

Interventions

BEHAVIORAL

Trunk exercise

Trunk stabilization exercises including the following components: (a) progressive deep abdominal muscle retraining (transversus abdominis), (b) progressive pelvic floor muscle retraining, (c) abdominal muscle strengthening exercises (rectus abdominis and obliques), (d) combination of abdominal muscle control and distal extremity movements, and (e) progressive functional exercises.

BEHAVIORAL

Inspiratory Muscle Training (IMT)

Inspiratory muscle strengthening exercises using inspiratory resistance (IMT devices)

BEHAVIORAL

Control Group

Participants in the Control Group will receive general management information for DRA, written instructions and a single educational exercise session for contracting the deeper abdominals and pelvic floor muscles.
