Pudental Nerve Function Test
Pudendal nerve function test studies the function of the nerves in the pelvic floor, which control the muscles in your back passage. This involves inserting a finger-sized probe, with a small electrode on it, through the back passage into the rectum.
A very small electric current is then passed over the nerves causing the pelvic floor muscles to twitch. You may feel a pulsing, twitching or prickling sensation in the back passage while we are taking measurements, which can be a little uncomfortable.
