Diaphragm Characteristics and Respiratory Muscle Function in Parous Women With and Without Diastasis Recti Abdominis

What this Trial Is About

Diastasis Recti Abdominis (DRA) is a common condition affecting many women after childbirth, where the abdominal muscles separate along the midline due to stretching. This condition may impact abdominal support, posture, breathing, and trunk function. Researchers are studying how DRA relates to diaphragm function and accessory breathing muscles, as little is currently known about this connection. The study aims to compare these muscle characteristics in women who have given birth, with and without DRA. This observational study divides adult women who have given birth into two groups based on the presence or absence of DRA, determined by standardized ultrasound imaging of the abdominal muscles. Participants undergo a single assessment session that includes rehabilitative ultrasound imaging (RUSI) to examine diaphragm thickness and movement during breathing. Inspiratory muscle strength is also tested using a POWERbreathe KH2 device. Additional information about pregnancy history and physical activity is collected. Women involved in the study will have one session where measurements of diaphragm thickness during inhalation and exhalation, diaphragm movement, and inspiratory muscle strength are taken. Demographic and clinical data such as age, body mass index, number of births, and time since last delivery are recorded. The main focus is to understand if women with DRA have altered diaphragm function or weaker respiratory muscles compared to those without DRA, which may guide future postpartum rehabilitation strategies.
