Abstract

Introduction and hypothesis

This study was aimed at comparing the efficacy of Knack maneuver training taught using different techniques on pelvic floor muscle (PFM) function, urinary symptoms, and perception of improvement in women with stress urinary incontinence (SUI).

Methods

We conducted a prospective nonrandomized study of 46 women with SUI. Assessments included: PFM functions (secondary outcome, SO) using a Myomed 932 EMG biofeedback device, urinary incontinence symptoms using the International Consultation on Incontinence Questionnaire Urinary Incontinence-Short Form (ICIQ-SF; primary outcome), the Urogenital Distress Inventory-6 (UDI-6; SO), and the Incontinence Severity Index (ISI; SO), and perception of improvement using the Global Perceived Impact scale. The women were divided into three groups according to their preference: group 1 (Knack maneuver training with electromyography biofeedback), group 2 (Knack maneuver training with verbal instruction), and group 3 (Knack maneuver training with vaginal palpation). An education program was also given to all women individually. The training program was 1 day per week for 4 weeks.

Results

There was an improvement in UDI-6, ICIQ-SF, and ISI scores in all groups (p<0.05). The maximum voluntary contraction (MVC) of the PFMs increased in group 2 (p=0.002), whereas both the MVC of PFMs and PFM contraction during Valsalva increased in group 3 (p=0.011 and p=0.042).

Conclusions

Regardless of the teaching methods, the Knack maneuver and education programs were effective on urinary symptoms in women with mild to moderate SUI. The Knack maneuver training with vaginal palpation and verbal instruction improved MVC of PFMs. All three different teaching methods might be used in SUI treatment programs.

In der MONARCHE-3-Studie lebten Frauen mit fortgeschrittenem Hormonrezeptor-positivem, HER2-negativem Brustkrebs länger, wenn sie zusätzlich zu einem nicht steroidalen Aromatasehemmer mit Abemaciclib behandelt wurden; allerdings verfehlte der numerische Zugewinn die statistische Signifikanz.
