The pelvic floor muscles are the muscles that form the base of the pelvis. While they are often only associated with dysfunction such as urinary incontinence, they are an important part of every day movement. They function as a “floor” to the “core.” Together with the diaphragm, these muscles – when contracted – can alter abdominal pressure and affect the tension of other muscles in the body. The main function of the pelvic floor muscles is to support the pelvic organs. They are also notably important in bladder and bowel as well as sexual function.
