Urinary incontinence is defined as the involuntary loss of urine. The urethra is the tube that carries urine to the outside of the body. The factors that must be present for stability in the low back and pelvic girdle are also required to close the urethra properly. These include:
Proper function of bones, joints, and ligaments
Proper function of muscles and fascia
Proper motor control (timing)
A recent multi-centered study in Holland found that 52% reported low back pain with pelvic dysfunction (difficulty voiding of urine or stool, incontinence, and/or sexual dysfunction). Of the 52%, 82% reported that symptoms began either with low back pain or pelvic pain. Physical therapy can help both of these conditions by restoring joint mobility, correcting alignment, restoring timing of the stabilizing muscle system, and retraining functional motions.
