ObjectiveDysfunction of the pelvic floor muscles (PFM) is associated with sexual dysfunction in women with stress urinaryincontinence (SUI). The EasyK7 device was developed to stimulate the PFM by surface electrical stimulation duringsitting (SESdS). We investigated the effects of SESdS on PFM function and sexual function in women with SUI. MethodsWomen with SUI were randomized into the SESdS and control groups. PFM function and sexual function wereassessed using a perineometer and the pelvic organ prolapse–urinary incontinence sexual function questionnaire (PISQ),respectively. After 8 weeks, the groups were compared using either analysis of covariance with the baseline values ascovariates or the paired Student’s t-test. ResultsThe final analysis included 16 subjects from each group. There were significant differences between the SESdS andcontrol groups after the intervention, as well as within the SESdS group between the pre- and post-interventionmeasurements. The P-values for the differences in PFM measurements between the groups, and between the preandpost- intervention measurements within the SESdS group, were 0.001 and 0.004 for power, 0.015 and 0.011 forstrength, and 0.012 and 0.034 for endurance, respectively. In addition, in the PISQ, there were significant differencesbetween the groups and between the pre- and post-intervention measurements within the SESdS group in thepartner-related domain (between groups: P=0.003; within SESdS group: P=0.024) and total score (between groups:P<0.001; within SESdS group: P=0.001). ConclusionSESdS can improve PFM function and sexual function in women with SUI. Trial RegistratiClinical Research Information Service Identifier: KCT0003357
