Mechanisms of Improving Fecal Continence Muscles Motor Function

The c-RED consists of a noncompliant cylindrical balloon (intra-anal balloon) that is connected to a small compliant balloon (external balloon) by a 2 mm diameter tube and a stopcock to allow for air to be filled and sealed in the system. The system is prefilled with air to determine the amount of air needed for a given internal pressure, or desired resistance of the intra-anal balloon. This is determined using a sphygmomanometer gauge in a sealed system.
