Efficacy of pelvic floor training with surface electromyography feedback for female stress urinary incontinence

Aims The aim of the study is to compare the efficacy of an 8-week pelvic floor muscle training program with surface electromyography feedback, performed in different body positions (supine, sitting, and standing), in women with stress urinary incontinence. Design This is a prospective observational study performed January 2014 to May 2016. Methods The training program was performed by 110 women with stress urinary incontinence, each completing 4 individual training sessions. The main outcome was the electromyography activity of the pelvic floor muscles and of the synergistic abdominal muscles. Outcome measures were evaluated at 4 time points, namely at baseline and at 2, 4, and 8 weeks of training. Results A notable effect of training was identified at week 2, which was sustained through to week 8. Training yielded a significant improvement in increased sustained voluntary contraction of the pelvic floor muscles in all 3 positions. The efficacy of training was influenced by the duration of training, age, body mass index, and history of vaginal delivery. Conclusion Training of the pelvic floor muscles, with positive reinforcement by surface electromyography feedback of the pelvic floor muscles and of the synergistic abdominal muscles, was effective for the treatment of stress urinary incontinence in women and should be considered as a feasible option by healthcare providers.
