Our abdomen has two layers of muscles: the rectus abdominus (the six pack muscle) and the transverse abdominus. The rectus abdominus is connected down the middle by a piece of connective tissue called the linea alba. When this connective tissue gets stretched or torn, the rectus muscle can become separated, which is known as Diastasis Recti (DR). DR often happens during pregnancy but can also occur in people who are not pregnant (including men and children). Physical therapy offers a number of ways to treat this separation while restoring optimal strength and stability to the core system as a whole.
