Stimulation therapy for bladder dysfunction

A medical system comprising:

• a therapy delivery module configured to generate and deliver electrical stimulation therapy to a patient;
• and
• a control module configured to:
• control the therapy delivery module to deliver electrical stimulation at a first stimulation intensity for a duration of a first time period, wherein the first time period is at least about 5 minutes, and wherein the first stimulation intensity is between about 50% and about 100% of a threshold stimulation intensity;
• control the therapy delivery module to cease delivering electrical stimulation at the first stimulation intensity for a duration of a second time period and deliver electrical stimulation at a second stimulation intensity for the duration of the second time period, wherein the second time period immediately follows the first time period, wherein the second stimulation intensity is less than the first stimulation intensity, wherein the electrical stimulation elicits an inhibitory physiological response related to voiding in the patient during the second time period, and wherein the second time period is at least about 5 minutes;
• and
• control the therapy delivery module to cease delivering electrical stimulation at the second stimulation intensity for a duration of a third time period and begin delivering electrical stimulation at the first stimulation intensity for the duration of the third time period, wherein the third time period immediately follows the second time period.
