1. A method, comprising:
- applying a first electrical signal to a neural structure at a first charge delivery rate according to a predefined pattern;
detecting an event;
applying a second electrical signal to the neural structure in response to detecting the event, thus applying a combined electrical signal comprising the first electrical signal and the second electrical signal to the neural structure, the combined electrical signal having a combined charge delivery rate exceeding the first charge delivery rate; and
in response to applying the second electrical signal, modifying a portion of the predefined pattern of the first electrical signal to generate a modified first electrical signal and applying the modified first electrical signal to the neural structure, the modified first electrical signal having a second charge delivery rate that is lower than the first charge delivery rate, thus causing said combined charge delivery rate to approach the first charge delivery rate.

Abstract
A method comprises applying a first open-loop electrical signal to a neural structure at a first rate. The method also comprises applying a closed-loop electrical signal to the neural structure in response to an event detection, thus causing an overall rate at which electrical stimulation is applied to the neural structure to exceed the first rate. The method further comprises applying a second open-loop electrical signal to a neural structure at a second rate that is lower than the first rate, thus causing the overall rate to be reduced to the first rate.
