It is well known that the abdominal wall plays a key role in how loads are transferred/controlled between the trunk and the extremities during all tasks. Non-optimal strategies for load transfer can have a significant, and long lasting, impact on the abdominal wall ultimately affecting both the form and function of the trunk and thus performance across multiple tasks (walking, running, continence, breathing etc). It is common to see non-optimal muscle synergies both during and after pregnancy (e.g. absent or delayed activation of transversus abdominis, over-activation of either internal or external oblique (neural system deficits)) that can perpetuate poor trunk motion/control and prevent the attainment of a woman’s postpartum goals (to run, jump, exercise etc). In addition, widening of the linea alba and separation of the recti (diastasis rectus abominis - myofascial deficits), while less common, may require surgical correction before training is successful. Diastasis rectus abdominis is often thought to only occur in women and be related to pregnancy and while this is the most common scenario seen in clinical practice, it is not the only one. The split abdominal wall can be seen in men who habitually use their abdominal wall non-optimally (usually by increasing intra-abdominal pressure) during loading tasks and, on occasion, after abdominal surgery.
Diane is well known both nationally and internationally for her clinical work on thoracic, lumbar and pelvic disability and pain. Her writing journey began in 1989 when Elsevier published the first edition of The Pelvic Girdle, which has been translated into several languages and updated in three subsequent editions. Diane is a co-founder of Discover Physio (along with Linda-Joy Lee) and is the owner, director and a practicing physiotherapy at Diane Lee & Associate sin White Rock, BC, Canada. Diane also serves as an editorial advisor for the journal Manual Therapy, a scientific committee member for the Interdisciplinary World Congress on Low Back and Pelvic Pain and is on the advisory board for Chicago's Woman's Health Foundation. She has been involved in clinical research pertaining to diastasis rectus abdominis after receiving a grant from the Clinical Center of Research Excellence (University of Queensland, Brisbane, Australia) and will share the results of this research during this lecture.
