Medical researchers have known for over 30 years that the sacral nerves control all the functions of the pelvis and its organs. Electrical impulses travel from the brain to the organs and muscles in the pelvis via the sacral nerves. These impulses are responsible for urinary and fecal elimination, muscle coordination, reproduction organs and the genitals. Sacral Nerve Stimulation is the introduction of gentle, soothing stimulation or pulsing just below the surface of the skin over the sacrum where the sacral nerves reside. The stimulation is provided by an implanted unit the size of a silver dollar. The unit is placed underneath the skin so as not to place limitations of any kind on the activities of the patient.
