Abstract
In general, the disclosure describes techniques for providing conditional electrical stimulation to a patient for pelvic health. An implantable medical device (IMD) may adjust the delivery cycle of the electrical stimulation applied to a patient in response to receiving a delivery cycle parameter associated with one or more of the following: a time in a time schedule, a control device output from a control device, and physiological information from a physiological information sensing device. As an example, the IMD may monitor a status of one or more inputs of the IMD and adjust the delivery cycle of the electrical stimulation applied to the patient based on the status of the input(s).
