Researchers have published new insights on pelvic floor muscle (PFM) dysfunction, which is one of the key risk factors for pelvic floor disorders, a set of morbid conditions that include pelvic organ prolapse and urinary and fecal incontinence, that impact close to a quarter of women in the U.S. and have a strong association with vaginal childbirth. The work is part of a larger effort to advance understanding, treatment and prevention of pelvic floor muscle dysfunction in humans.
