title: Natural resolution of rectus abdominis diastasis. Two single case studies.
abstract: An increase in inter-recti distance (IRD) is common in the peripartum period, but is not well documented. This study evaluated the IRD from 36 weeks of gestation to 12 weeks postpartum using two single case studies. Measurements were taken with the rectus abdominis at rest and during contraction at three levels along the linea alba, using a pair of dial calipers. The maximum divarication in the antenatal period was 58mm (resting) and 55mm (active) at the level of the umbilicus. An increase of 200 to 400% was demonstrated at 12 weeks postpartum vis-à-vis the 36th week of gestation. In conclusion, despite individual variability, IRD persists in the postpartum period. Further study is required to establish generalisation.
