In clinical practice, the distance between the rectus abdominis muscle and the midpoint of the stomach can be determined by lying on the back and straining the rectus abdominis muscle to determine the degree of separation of the rectus abdominis muscle by a few fingers. To measure the degree of diastasis recti separation in a woman, the woman is asked to lie flat on her back and bend her knees, and then the tension in the diastasis recti muscle is felt by raising her head, for example. When the muscles in the abdomen are tense, it can be felt from the abdominal wall, and the degree of diastasis recti separation can be determined by judging the distance between the tense area and the midline. If the rectus abdominis muscle is separated by less than two fingers, then it can be relieved on its own. If the separation is more than three fingers, it may cause hernia and other conditions that require active treatment. When the rectus abdominis muscle separation occurs, it is recommended to consult a doctor and take appropriate treatment under the doctor’s guidance to promote the improvement of symptoms.
