Brain input influence on pelvic floor muscles.

In recent studies, non-invasive magnetic stimulation of the brain has been suggested as an ideal and pain-free way to evaluate the way in which the brain controls the pelvic floor muscles. However for clinical and research purposes, we need to be sure that measures obtained are repeatable- that is, that the numbers produced on one day are closely related to the numbers produced on a second day, when no treatment may have altered the measures. Through this study we are testing the response of the pelvic floor muscles to magnetic stimulation of the brain on two separate days to determine if the pelvic floor muscle responses are comparable between the days.  

It is expected that the results of this research will help us to determine if this measurement tool can be used in clinical and research contexts.
