Abstract

Background: Diastasis recti is defined as an interrecti distance (IRD) over 23 mm in Beninese postpartum women. Its prevalence is 46%. The Curl-up acutely reduces the IRD but it increases the linea alba distortion and it is considered to be hyperpressive. When Curl-up is combined with Diaphragmatic aspiration (DA) the intra-abdominal pressure is lower. Moreover, combining Curl-up with transversus abdominis activation is recommended to decrease the linea alba distortion. However, the effect of this DA combined with Curl-up on the IRD is not known in postpartum women. 
Objectives: To study the acute effect of the DA combined with Curl-up, and of other abdominal exercises on IRD. 
Methods: Beninese postpartum women diagnosed with diastasis recti participated in this cross-sectional study. IRD was measured at 5 cm above umbilicus with an ultrasound in 6 conditions performed in random order: rest, DA, Curl-up, Drawing-in, DA+Curl-up, Drawing-in+Curl-up. Values were expressed as median ± IQR and IRD was compared across these conditions using Friedman test and Wilcoxon test for post-hoc pairwise comparisons.
Results: Forty-nine women aged between 22 and 39 participated in this study. Compared to rest (26.7 ± 9.5 mm), no significant IRD difference was observed during either DA (26.0 ± 8.5 mm) or Drawing-in (29.0 ± 10.0 mm), but IRD during Drawing-in was significantly larger than that during DA. Curl-up (18.7 ± 8.9 mm), Drawing-in+Curl-up (22.9 ± 9.7 mm) and DA+Curl-up (21.8 ± 9.3 mm) decreased the IRD (p<0.001). This decrease was the largest during Curl-up (p<0.001). 
Conclusion: Compared to rest, DA and Drawing-in did not decrease IRD but their combination with Curl-up slightly decreased IRD. Future studies are needed to investigate the acute effect of the combination of DA with Curl-up on the linea alba distortion.
Clinical Implication: Physiotherapists are regularly confronted with the management of the diastasis recti in postpartum women. DA combined with Curl-up can be used for management of diastasis recti in postpartum.
