PFM training - defined as a program of repeated voluntary PFM contractions taught and supervised by a health care professional - is the most commonly used physiotherapy treatment for women with SUI and is effective in the treatment of female stress and mixed urinary incontinence and, therefore, is recommended as a first-line therapy (Dumoulin et al, 2014; Bø, 2012). As recommended by the International Consultation on Incontinence (ICI) PFM training should generally be the first step of treatment before surgery (Abrams et al, 2010). However, standard SUI physiotherapy concentrates on voluntary contractions even though the situations provoking SUI such as sneezing, coughing, jumping and running (Haylen et al, 2010) require involuntary fast reflexive pelvic floor muscle contractions. Although training procedures following the concepts of training science and sports medicine are generally well known and widely implemented in rehabilitation and sports (ACSM, 2009; Schmidtbleicher & Gollhofer, 1991), the optimal, and well standardized training protocol for involuntary, fast, and reflexive PFM contractions still remains unknown.
