One in four women with stress urinary incontinence who are taught “the knack” maneuver adopt this motor pattern while coughing: A prospective interventional cohort study

Abstract

AbstractQuestionsDo women with stress urinary incontinence (SUI) who receive instruction to perform the knack maneuver as part of a 12‐week pelvic floor muscle training (PFMT) program perform it during voluntary coughing without specific instruction to do so, and are subjective and objective outcomes better among those who do than among those who do not demonstrate the knack during voluntary coughing?DesignSecondary analysis of a prospective interventional cohort.ParticipantsWomen with SUI.Intervention12‐week PFMT intervention including instruction to perform the knack.Outcome measuresPerformance of the knack before a voluntary cough as confirmed through ultrasound imaging. SUI severity determined subjectively (International Consultation on Incontinence Modular Questionnaire‐Female Lower Urinary Tract Symptoms [ICIQ‐FLUTS] overall score, ICIQ‐FLUTS UI subscale score, 3‐day bladder diary) and objectively (30‐min pad test).ResultsOutcome data were available from 69 participants. At baseline, no participants performed the knack when asked to cough. At follow‐up, more participants performed the knack during a voluntary cough [18/69 (26%), 95% confidence interval [CI] 15%–35%] than at baseline. The extent of improvement in SUI symptoms was not different between participants who did and did not demonstrate the knack during a voluntary cough [FLUTS‐UI subscale score (d = 0.31, 95% CI –0.78 to 2.77, n = 69), FLUTS overall score (d = 0.26, 95% CI −1.52–4.23, n = 69), 30‐min pad test (d = 0.03, 95% CI −9.35 to 10.32, n = 69), 3‐day bladder diary (d = 0.03, 95% CI −4.07 to 3.60, n = 51)].ConclusionApproximately one in four women appear to adopt the knack as a motor response to a cough command, however, adopting the knack was not independently associated with greater improvements in SUI.
