may be ruled out using ultrasound. In infants, they typically result from a minor defect of the linea alba between the rectus abdominis muscles. This allows tissue from inside the abdomen to herniate anteriorly. On infants, this may manifest as an apparent 'bubble' under the skin of the belly between the umbilicus and xiphisternum (bottom of the breastbone). Examination is performed with the subject lying on the back, knees bent at 90° with feet flat, head slightly lifted placing chin on chest. With muscles tense, the examiner then places fingers in the ridge that is presented. Measurement of the width of separation is determined by the number of fingertips that can fit within the space between the left and right rectus abdominis muscles. Separation consisting of a width of 2 fingertips (approximately 1 1/2 centimeters) or more is the determining factor for diagnosing diastasis recti. Diagnosis Diastasis recti can be diagnosed by physical examination, which may include measuring the distance between the rectus abdominis muscles at rest and during contraction at several levels along the linea alba. Abdominal ultrasonography provides objective evidence for the diagnosis, and also confirms that the bulge is not a hernia. An abdominal CT scan is an acceptable alternative to an ultrasound. Treatment During pregnancy - No treatment is necessary for women while they are still pregnant. After delivery - Typically the separation of the abdominal muscles will lessen in the mother within the first 8 weeks after childbirth; however, the connective tissue remains stretched for many. The weakening of the musculature may also cause lower back pain, weakened pelvic alignment, and altered posture. For many, Diastasis Recti is a condition which they have to live with for many years later In children - Complications include development of an umbilical or ventral hernia, which is rare and can be corrected with surgery. If an infant with the condition develops vomiting, or redness or pain in the abdominal area, medical attention should be sought. Strength training A systematic review of the evidence found that exercise may or may not reduce the size of the gap in pregnant or postpartum women. The authors looked at 8 studies totaling 336 women and concluded: "Due to the low number and quality of included articles, there is insufficient evidence to recommend that exercise may help to prevent or reduce DRAM," or diastasis of the rectus abdominis muscles, also stating that "non-specific
