This is a good article talking about visceral manipulation for Diastasis recti (DR), I have had good success with some women in helping reduce their diastasis, some were within 1 to 2 years of having their child, in another case the DR had been there for a long time. Whats amazing is the simplicity of the technique. This also point out the need to balance the person's pelvis via reducing tension in the psoas, iliacus and then the posterior musculature.
Why Do I Still Look Pregnant: Part II
By Fiona McMahon, DPTDiastasis recti (DR) can be the bane of many women who are trying to decrease the size of their stomach following pregnancy. DR occurs when the two six pack muscles (rectus abdominus) separate from one another, leaving the appearance of visible gapping and bulging of the stomach, creating the look of a belly or paunch. We most commonly see DR following pregnancy; however, it can be seen in men and women with abdominal obesity, children with bowel issues, and people who have undergone abdominal surgery. Aside from its cosmetic effects, DR can also cause problems with the low back, bowel, and bladder.
