Covid-19 Delays and Upcoming eBook Edition

Unfortunately due to impacts of Covid-19 it has become too expensive to ship to certain parts of the world with tracking and delivery can take months. As a result we are currently developing an eBook version of the DRA Guide. We expect this to be available around the end of July 2022.

A Clinical Guide for Those who are Split Down the Middle

It is well known that the abdominal wall plays a key role in function of the trunk and that pregnancy and delivery can have a significant, and long lasting, impact on both its appearance and function. Widening of the linea alba and separation of the recti, known as diastasis rectus abdominis (DRA), may impact both the appearance of the abdomen and the function of the trunk and many believe that closure of the DRA is a pre-requisite for improving appearance and function.  Women with this condition often ask whether surgery will help them and currently there are no evidence-based guidelines for clinicians to know which patients with DRA are appropriate for conservative treatment and which ones will also require surgery. Who to treat, who to refer and how to close the DRA were the initial questions in 2006 that prompted further study (and ultimately this clinical guide) for this subgroup of postpartum women.

  • How wide can the linea alba be and still ensure a functional abdominal wall?
  • What is the best way to close the DRA and restore both the appearance and function of the abdominal wall? Is closing a DRA necessary or the best goal?
  • Are there key clinical findings that suggest when surgery should be recommended for postpartum women with DRA?

Clinical Guide Research

After over a decade of clinical and research enquiry on best ways to help postpartum women recover their abdominal wall appearance and function, the answers to these questions are becoming clear. This clinical guide, complete with over 130 online videos, will present an evidence-based approach (current available research combined with clinical expertise) for clinicians and trainers working with postpartum women who aim to improve the function and appearance of their abdominal wall.

Book Review on

The creator and author of is Matthew S. Thomason PT, DPT, OCS, CFMT, FFMT, CMPT, FAAOMPT has posted his review of the DRA Guide.  Here are some highlights.

“Clinicians that are interested in this particular field of physical therapy should read this book right away.  And don’t let the title limit that audience.  Diane does a wonderful job throughout the entire text explaining how abdominal wall dysfunction impacts wide ranging problems throughout this region of the human body.”

“The concepts presented in this clinical guide are not overly complex, but are presented in a very logical and evidence-based manner.”

“The reader (myself) quickly understands the paucity of guidance that we clinicians have to treat, manage, or direct care for conditions that compromise the abdominal wall (LBP, PGP, POP, UI, DRA).”

“Each layer of the abdominal wall is described and detailed with phenomenal pictures of fresh cadavers, coronal sections of (not so fresh) cadavers, and pictures from Guimberteau and Armstrong’s Architecture of Human Living Fascia.  The most important part of this chapter though is how Diane ties in all their inter-related function.”

“One very nice feature for this book is the use of QR codes that are placed throughout each chapter. These link to online videos that show live patients for assessment and treatment demonstrations. Another benefit of these linked videos are the images of real-time ultrasound that Diane has performed on her patients to further give credence to the concepts that she presents in this clinical guide.”

  1. Well recommended course for professonal and client


    Very well explained from theory to proof (evidence and ultrasound), to practice. Detailed explanation, conditions plus progression of exercise. Very much enjoyed reading and watching. Thank you.

  2. I will read and watch this many times. A great course with lots of practical information.


    One of the benefits of the internet is that experts like Diane get to share their knowledge with many more practitioners. I loved the ultrasound videos. I’ve taught many of these exercises for years but watching and rewatching has helped me really understand the deep system more.

  3. DRA Guide supplemental videos


    Very informative. The video demonstrations were helpful to understand the exercises.

  4. Very good information


    Very good course with a lot of valuable theoretical and practical information. The best part was video

  5. DRA Guide


    Exceptional book and videos. Diane Lee is obviously an exceptional therapsit, teacher,mentor, and author. We are very blessed to have such an amazing lady learn, understand and then teach such valuable information. Thank you. Warmly Jennifer Williamson BScPT, Msc.PT, DOMP.

  6. diastasis recti


    I felt this book was very well written and covered this topic effectively. I felt it helped me to develop my evaluation skills and helped to build my clinical skills in exercise progression. Would highly recommend this book to any therapist treating abdominal issues.
