To assess the degree of dysfunction, three measurements must be taken into account. First, an anatomic landmark known as the pubococcygeal line must be determined, which is a straight line connecting the inferior margin of the pubic symphysis at the midline with the junction of the first and second coccygeal elements on a sagittal image. After this, the location of the puborectalis muscle sling is assessed, and a perpendicular line between the pubococcygeal line and muscle sling is drawn. This provides a measurement of pelvic floor descent, with descent greater than 2 cm being considered mild, and 6 cm being considered severe. Lastly, a line from the pubic symphysis to the puborectalis muscle sling is drawn, which is a measurement of the pelvic floor hiatus. Measurements of greater than 6 cm are considered mild, and greater than 10 cm severe. The degree of organ prolapse is assessed relative to the hiatus. The grading of organ prolapse relative to the hiatus is more strict, with any descent being considered abnormal, and greater than 4 cm being considered severe.[2]

Building and maintaining a strong pelvic floor is crucial for women of all ages. The pelvic floor is a group of muscles at the bottom of your pelvis that supports the womb, bladder, and bowels. So if these muscles become weak—whether it's due to childbirth, pregnancy, aging, or weight gain—it may be challenging to control your bladder and bowel activity. This is referred to as incontinence, a condition that affects nearly 25 million Americans, 75% to 80% of which are women.
You’ve likely already heard of kegels, the most common method for strengthening the pelvic floor. But there are plenty of additional exercises you can try to help train your pelvic floor. Watch this video to see yoga and fitness expert Kristin McGee (who recently gave birth to twins!) demonstrate three simple yet effective moves for strengthening your pelvic floor.
