Pelvic floor dysfunction is an umbrella term for a variety of disorders that occur when pelvic floor muscles and ligaments are impaired. Although this condition predominantly affects females, up to 16% of males suffer as well. Symptoms include pelvic pain, pressure, pain during sex, incontinence, incomplete emptying of feces, and visible organ protrusion. Tissues surrounding the pelvic organs may have increased or decreased sensitivity or irritation resulting in pelvic pain. Underlying causes of pelvic pain are often difficult to determine. The condition affects up to 50% of women who have given birth.
Paradoxical Puborectalis Contraction: The puborectalis muscle is part of the control muscles that control bowel movements. The puborectalis wraps like a sling around the lower rectum. During a bowel movement, the puborectalis is supposed to relax to allow the bowel movement to pass. If the muscle does not relax or contracts during paradoxical contraction, it may feel like you are pushing against a closed door.
