1. A method comprising:
- determining an amplitude of each of a multiplicity of stimulation signals each corresponding to a distinct channel included in an implantable stimulation system;
using said amplitudes of said stimulation signals to determine a plurality of probabilities, each probability within said plurality of probabilities corresponding to a different stimulation signal within said multiplicity of stimulation signals;
obtaining a plurality of random numbers, each random number within said plurality of random numbers corresponding to a different stimulation signal within said multiplicity of stimulation signals;
identifying each stimulation signal included in the multiplicity of stimulation signals that has a corresponding probability greater than a corresponding random number;
selecting the identified stimulation signals to be applied to a patient during a stimulation frame; and
applying the selected stimulation signals to the patient during the stimulation frame through a subset of a total number of channels in the implantable stimulation system.

Abstract
Methods of selecting a number of channels for stimulation within a neural stimulation system include determining an amplitude of a multiplicity of stimulation signals each corresponding to a channel within a multiplicity of channels in the implantable stimulation system, using the amplitudes of the stimulation signals to determine a probability of each of the stimulation signals, and using the probabilities of one or more of the stimulation signals to randomly select a predetermined number of channels from the multiplicity of channels through which one or more of the stimulation signals are applied to a patient during a stimulation frame.
