Claim One:
1. A method of providing electrical neurostimulation therapy to a patient to treat a medical condition, wherein said electrical neurostimulation therapy includes both an open-loop therapy mode and a closed-loop therapy mode and is characterized by a combined rate of electrical charge delivery to a neural structure, the method comprising: applying a first open-loop electrical signal to the neural structure, said first open-loop signal defined by a plurality of parameters and characterized by a first open-loop rate of electrical charge delivery to the neural structure, said first open-loop rate determined by said plurality of parameters defining said first open-loop signal; in response to a detection event, applying a closed-loop electrical signal to the neural structure, thereby causing said combined rate of electrical charge delivery to exceed said first open-loop rate; adjusting at least one of said plurality of parameters defining said first open-loop signal to define a second open-loop electrical signal characterized by a second open-loop rate of electrical charge delivery less than said first open-loop rate; applying said second open-loop electrical signal to said neural structure according to the second open-loop rate until said combined rate of electrical charge delivery is reduced to said first closed-loop rate; and resuming applying said first open-loop electrical signal to said neural structure.
