Biofeedback and the electromyographic activity of pelvic floor muscles in pregnant women.

Background: Maintaining continence is among the functions of the pelvic floor muscles (PFM) and their dysfunction can cause urinary incontinence (UI), which is a common occurrence during pregnancy and the puerperal period. Pelvic floor muscle training (PFMT), therefore, is important during pregnancy, although most women perform the muscle contractions unsatisfactorily.

Objectives: This study is an exploratory analysis of the results of three electromyographic (EMG) activity biofeedback sessions in pregnant women.
