The MBY Education Synergy Series Presents

Managing Diastasis Recti Based On Current Research & Clinical Expertise: An Update for Pilates Movement Professionals


Melanie Byford-Young Presents Diane Lee


Friday, June 14, 3 pm - 5 pm PST

Livestreaming on Zoom


This session will be recorded and available to all registrants for 7 days.


Melanie is thrilled to have the opportunity to host Diane Lee to share current perspectives on the science and art of managing rectus diastasis. Many women, and men, develop a separation of the linea alba and/or rectus abdominis of varying sizes and magnitudes of dysfunction. Over the years, the study of how to measure, interpret and manage a DRA has evolved, and yet there are still misconceptions and divergent opinions.  During this presentation, Diane Lee will share her wealth of knowledge on the topic of Diastasis (DRA). This presentation will help movement professionals understand the current science, interpret the literature, and update their Pilates approach.

Diane Lee's Presentation Overview

Title: The Inter-recti distance and Diastasis Rectus Abdominis: Is the IRD a valid measurement to inform care for DRA?
There are many unknowns surrounding diastasis rectus abdominis (DRA), particularly whether intervention should aim to reduce the inter-recti distance (IRD) or improve the transmission of force between sides, which reduces the distortion of the linea alba but with increased IRD; whether IRD changes over time; and the factors that influence management choices. The IRD is often measured in research at a limited number of time points; whereas clinically it is measured at almost every visit. Decisions for prognosis of severity of DRA, intervention (training vs surgery), and outcome over time (what happens to the width of this gap) are often based on this measure.

Evolving evidence, and clinical experience, support that there is no validity for the sole use of the IRD in this condition. In other words, the distance or gap, between the recti are not a valid indicator for

1.     Classification of severity of DRA
2.     How to intervene/prescribe treatment/exercises
3.     Predicting outcome.

Distortion of the linea alba, and its relationship to the IRD, is likely the more valid measure particularly over time.

This presentation will present the results of 3 studies (1 published and 2 in submission) to support the conclusion that for many individuals with DRA, the IRD does not change beyond the natural period of healing and is not impacted by exercise training, whereas distortion of the linea alba is.

During this workshop, you will learn:

  • Understand what is meant by DRA and IRD
  • How DRA and IRD are measured and their significance
  • Understand how diastasis can vary during postpartum stages
  • Understand how to cue the core for clients with DRA
