Performing pelvic-floor muscle training can improve symptoms of urinary incontinence, but there is no benefit to adding electromyographic biofeedback, a study suggests.

In a randomised trial that included nearly 600 women with urinary incontinence, researchers saw no benefit at the end of two years from adding electromyographic biofeedback to pelvic floor muscle training.

The researchers from Glasgow Caledonia University in the UK wrote that overall electromyographic biofeedback should not be routinely offered as part of pelvic-floor muscle training.

Electromyographic biofeedback makes use of a vaginal probe to capture the electrical activity of the pelvic floor muscles, which is displayed on a screen, the researchers explain in the BMJ.
