Systems and methods for enhancing or affecting neural stimulation efficiency and/or efficacy
First Claim
1. A method for treating a neurological condition of a patient, comprising:
- applying electromagnetic signals to a patient'"'"'s nervous system over a first time period with a first waveform having a first set of parameters; and
applying electromagnetic signals to the patient'"'"'s nervous system over a second time period with a second waveform having a second set of parameters, wherein at least one parameter of the second set is different than a corresponding parameter of the first set, and wherein the at least one parameter is selected to resume, at least approximately maintain, or resume and at least approximately maintain a therapeutic benefit resulting from signals applied during the first time period.

Abstract
Systems and methods for enhancing or affecting neural stimulation efficiency and/or efficacy are disclosed. In one embodiment, a system and/or method may apply electromagnetic stimulation to a patient'"'"'s nervous system over a first time domain according to a first set of stimulation parameters, and over a second time domain according to a second set of stimulation parameters. The first and second time domains may be sequential, simultaneous, or nested. Stimulation parameters may vary in accordance with one or more types of duty cycle, amplitude, pulse repetition frequency, pulse width, spatiotemporal, and/or polarity variations. Stimulation may be applied at subthreshold, threshold, and/or suprathreshold levels in one or more periodic, aperiodic (e.g., chaotic), and/or pseudo-random manners. In some embodiments stimulation may comprise a burst pattern having an interburst frequency corresponding to an intrinsic brainwave frequency, and regular and/or varying intraburst stimulation parameters. Stimulation signals providing reduced power consumption with at least adequate symptomatic relief may be applied prior to moderate or significant power source depletion.
