Details and patient eligibility

About

Demonstrate a response to stimulation of the posterior tibial nerve using the Biowave device and a microneedle patch electrode in patients with overactive bladder symptoms. The investigators hypothesize that after at least 6 weekly treatments there will be modest improvements in overactive bladder symptoms trending toward more improvement.

Full description

Women 18 years old and over with a score of equal to or greater than 4 on the OAB-q short form for urgency and average daily urinary frequency equal to or greater than 10 times based on a 3-day voiding diary plus other inclusion criteria will be reviewed for possible enrollment in this study. Outcomes measured include Global Response Assessment (GRA) for overall bladder symptoms, a change in the 3-day voiding diary parameters and adverse events.
