Abstract

OBJECTIVES:

€‚ Neuromuscular electrical stimulation (NMES) is commonly used to treat lower urinary tract dysfunctions. This study evaluated the efficacy of a novel externally applied stimulator in the treatment of stress urinary incontinence (SUI).

MATERIALS AND METHODS:

€‚ Nine women were included in this study. Provocative tests included a cough and jumping jack test assessed via pad weight. Ultrasound (US) imaging assessed pelvic floor muscle (PFM) contraction. A bladder filling protocol allowed for delineation of the bladder from the pelvic floor and standardized volume. External electrodes were used during 30 €ƒmin, at least four times per week treatment protocol at home for eight weeks. Participants were blinded to US and were not instructed regarding pelvic floor contractions.

RESULTS:

€‚ At week 1, participants could perform PFM contractions verified with US. More importantly, an 87.43% decrease in leakage was noted. At week 8, participants reported a 97.71% decrease in leakage (p= 0.0001). Changes noted in Incontinence Impact Questionnaire and Modified Oxford scores were significant (p= 0.0001 and p= 0.0001).

CONCLUSIONS:

€‚ NMES is frequently used to promote muscle strength and coordination. Studies have shown NMES to be effective in decreasing symptoms associated with SUI; however, few, if any, have used it as a primary treatment modality. The novel device in this study was shown to be effective in improving muscle strength, reducing or ablating the symptoms associated with SUI, and in eliciting PFM contractions. The device is noninvasive and can be used as a home treatment.
