Rapid frequency cycling during electrical stimulation

A method of rapid frequency cycling during electrical stimulation, the method comprising:

• determining, by a controller of an electrical stimulation system, a plurality of frequency band groupings of discrete frequency bands of an electrical stimulation signal having a frequency range, wherein each frequency band grouping of the plurality of frequency band groupings includes at least one discrete frequency band, wherein at least one of a corresponding current amplitude or a corresponding voltage amplitude of the electrical stimulation signal is independently tuned within each of a plurality of the discrete frequency bands based on feedback received by the controller;
• determining, by the controller, a random sequence of the frequency band groupings;
• generating, by at least one signal generator controlled by the controller, the electrical stimulation signal according to the determined random sequence of the frequency band groupings;
• and
• delivering the generated electrical stimulation signal through an electrode array to a patient to provide therapy to the patient.
