As many as 50 percent of people with chronic constipation have pelvic floor dysfunction (PFD) — impaired relaxation and coordination of pelvic floor and abdominal muscles during evacuation. Straining, hard or thin stools, and a feeling of incomplete elimination are common signs and symptoms. But because slow transit constipation and functional constipation can overlap with PFD, some patients may also present with other signs and symptoms, such as a long time between bowel movements and abdominal pain.

What sets pelvic floor physical therapists apart is their in depth understanding of the muscles and surrounding structures of the pelvic floor, beyond what was taught in physical therapy graduate school. What that means for a patient who is seeking the help of a pelvic floor physical therapist, is that his or her pelvic floor issues will be examined and treated comprehensively with both internal and external treatment, provide them with lifestyle modifications to help remove any triggers, and receive specific exercises and treatment to help prevent the reoccurrence of pain once he or she has been successfully treated.
When mechanical, anatomic, and disease- and diet-related causes of constipation have been ruled out, clinical suspicion should be raised to the possibility that PFD is causing or contributing to constipation. A focused history and digital examination are key components in diagnosing PFD. The diagnosis can be confirmed by anorectal manometry with balloon expulsion and, in some cases, traditional proctography or dynamic magnetic resonance imaging defecography to visualize pathologic pelvic floor motion, sphincter anatomy and greater detail of surrounding structures.
Stephanie Prendergast, a pelvic floor physical therapist who is a co-founder and LA’s clinical director of the Pelvic Health & Rehabilitation Center, says that while information on pelvic floor issues isn’t always easily accessible, doctors can spend some time online looking at medical journals and learning about different disorders so they can better treat their patients.
