A 36-year-old female who gave birth to three children over the span of nine years is referred to physical therapy during her fourth pregnancy. The patient presents with complaints of involuntary urine leakage when she coughs or sneezes and when she participates in an aerobics class. Which type of incontinence is MOST consistent with the described presentation?

• A. Urge
• B. Functional
• C. Overflow
• D. Stress

Answer: (D)

Leakage with activities that raise intra-abdominal pressure, such as coughing, sneezing, or exercising, points to stress incontinence. This occurs when the pelvic floor and urethral support are weakened (often from childbirth and pregnancy), so the urethra cannot stay closed during sudden increases in pressure. In multiparous women, the pelvic floor may be stretched or weakened, leading to urethral hypermobility and reduced urethral closure pressure. The result is leakage during tasks that load the pelvis, rather than a need to urinate urgently or leakage from bladder emptying problems. This differs from urge incontinence (leakage with a strong, uncontrollable urge to void), functional incontinence (leakage due to inability to reach the toilet), and overflow incontinence (dribbling from a bladder that’s overfilled or obstructed). Therefore, the described presentation best fits stress incontinence.
