The revolutionary contoured shape of the Anuform® provides a sound electrode/tissue interface which allows for comfortable muscle stimulation and accurate biofeedback. As Anuform always sits in the same position, comparable EMR readings can be taken over different sessions. When the Anuform® is inserted, the probe allows the anal sphincter to close around the narrow neck of the probe. This secures the correct positioning without the need for holding the probe in place. Revolutionary shape for repeatable positioning and ambulatory use.
