Which of the following interventions is most aligned with the KNACK technique?

• A. Teaching rapid pelvic floor contractions during arousal
• B. Conscious contraction of pelvic floor muscles to prevent leakage during coughing
• C. Routine long-duration pelvic floor contractions
• D. Deep breathing with relaxation of pelvic floor muscles

Answer: (B)

The KNACK technique centers on a quick, preemptive pelvic floor contraction to tighten the urethra just before and during activities that raise intra-abdominal pressure, like coughing. This brief, conscious squeeze helps prevent leakage by increasing urethral closure at the critical moment. That’s why the best choice describes consciously contracting the pelvic floor to stop leakage during coughing. It isn’t about arousal, and it isn’t about long, sustained contractions; KNACK is deliberately brief and rapid to respond to sudden pressure. It also wouldn’t be achieved by deep breathing with pelvic floor relaxation, which would lessen urethral support when leakage risk is highest.
