Distinct viscoelastic behavior of internal and external rectus abdominis fascia, consequences for our notion of abdominal wall function.

Abstract

Introduction: In recent decades fascia has gained scientific interest, underpinning its unique role in physical function. Several studies consider the abdominal fascia as a stabilizer of the spine (Hodges et al 2003; Stokes et al 2010). From an evolutionary perspective, this is peculiar because bone developed much later than fascia (Perry et al 2010). Should it not be the other way around: the spine as subordinate to fascia? To explore this notion we need a better understanding of the function of fascia. This study explores the viscoelastic behavior of internal and external rectus abdominis fascia, as significant components of the abdominal fascial system (Deeken & Lake, 2017).
