In the suspicion of an abdominal rectus abdominis diastasis, many people who present with some symptoms of the disease, feel the need to test its presence with self-assessment before even a proper specialist visit.
Subject position and ideal environment
In a quiet environment with adequate lighting the subject should be lying on the ground (gym mat is useful). It is necessary to expose the entire abdomen avoiding that clothing such as sweaters or sweaters obstruct the vision. A common mistake is to perform the test in one's own bed. The spinal column and the pelvis in fact must find a rigid support during the movements and the bed is not the right place.
Movements to be performed
Starting from the resting condition completely lying down with the head resting on the ground raise your legs slightly, keeping them together and rigid without bending the knees.
Keeping the position (rather tiring) one could notice the eversion improperly called "fin" by some. This deformity visible under stress is nothing but the effect of increased intra-abdominal pressure on the area of weakness caused by the pathology. It is frequent to find umbilical eversion suggestive of hernia in this location.
Returning to the resting condition, the deformity may disappear, but touching the hand, perpendicular to the midline(see pictures), you may feel an area of compliance precisely located where under stress the deformity was noted.
On either side of this area of compliance, it is common to perceive the two margins of the rectus muscles. It is useless to risk evaluating the maximum muscular distance (IRD - Inter Recti Distance), which should instead be measured more precisely during the specialist examination, using the appropriate instrumental tests if necessary.
In subjects who are particularly thin and have a thin adipose layer, the self-assessment is more reliable. A thick adipose layer, on the other hand, frequently masks any underlying abdominal wall defect. Finally, it should be remembered that the only valid and precise diagnosis is that of the surgeon after an appropriate examination and accompanied by any additional tests.
