Randomized controlled trial comparing the effectiveness of core stability exercise, static abdominal contraction, and yogic diaphragmatic breathing in reducing inter-recti distance in postnatal women with diastasis recti abdominis: Protocol for a randomized controlled trial

Diastasis recti abdominis, also known as DRA, is a disorder that occurs after childbirth and is defined by the separation of the rectus abdominis muscles along the linea alba. This disease has the potential to make core function, musculoskeletal stability, and quality of life difficulties. Objective: To compare the efficacy of core stability exercise, static stomach contraction, and yogic diaphragmatic breathing versus core stability exercise alone in reducing inter-recti distance among postnatal women. Methods: A single-blind randomized skilful trial will train 24 postnatal women (3-6 months postpartum) with clinically confirmed DRA from the Wardha community. Participants will be randomized (1:1) into an experimental group (combined interventions) or a comparison group (core stability only). Both groups will train 3× weekly for 8 weeks. Primary outcome: change in inter-recti distance measured using a digital nylon calliper. Results: It is anticipated that the experimental group will demonstrate significantly greater reductions in inter-recti distance than the comparison group following the 8-week intervention. Conclusions: Findings will provide high-quality evidence regarding effective, non-surgical rehabilitation strategies for postpartum DRA.
