Background: Diastasis Recti Abdominis (DRA) can occur during pregnancy and postpartum [1-7]. It is defined as an increase of the inter-recti distance (IRD) beyond normal values . The diagnosis of DRA is inconsistent within the literature and varies depending on measurement instrument  and activity during measurement (rest versus active curl-up). DRA is characterized by the stretching of linea alba (LA) and contributes to a protrusion of the anterior abdominal wall due to increased laxity in the myofascial system that supports abdominal viscera . DRA has been postulated to affect lumbopelvic support and function due to laxity of the LA and altered angle of muscle insertion [6, 11-13], but recent studies have not confirmed this [5, 7, 14]. Risk factors for the development of DRA have been investigated in pregnancy to 12-months postpartum [4, 5, 7, 15-20]. Objective: Rehabilitation for DRA has been traditionally focused on reducing the IRD, but recent research has proposed that a sole focus on closing the DRA is suboptimal . Results: It is important alongside the rehabilitation of the abdominal wall that there is the consideration of the pelvic floor (PF). In healthy individuals, with the activation of the transversus abdominis, there is a sub-maximal co-contraction of the PF muscles [21-23]. This co-contraction can be lost or altered in women with urinary incontinence . An increase in intra-abdominal pressure without simultaneous co-contraction of the PF may cause caudal displacement of the PF . Conclusion: The aim of this review is to bring the reader up to date on the evidence on DRA and to propose a rehabilitation framework for the whole abdominal wall in DRA with consideration of the impact on the PF.
