Pelvic Muscle Dysfunction (PMD) or Pelvic Floor Dysfunction (PFD) is a specialized biofeedback treatment area, which covers elimination disorders and chronic pelvic pain syndromes. These disorders include: urinary and anal incontinence, chronic constipation resulting from pelvic floor dyssynergia, bladder sphincter dyssynergia, pelvic floor myalgias and vulvodynia.

What causes Pelvic Floor Dysfunction?

Pelvic Floor Dysfunction is caused by a weakness of the muscles in the pelvis surrounding the anus and rectum. However, because this group of muscles is voluntarily controlled to some extent, biofeedback training is somewhat successful in retraining the muscles to function normally and improving the ability to have a bowel movement.

Functional constipation that stems from problems in the structure of the anus and rectum is known as anorectal dysfunction, or anismus. These abnormalities result in an inability to relax the rectal and anal muscles that allow stool to exit.

People with IBS predominantly experiencing constipation also have pain and bloating as part of their symptoms.
