1. A patient therapy system, comprising:
a signal generator coupleable to at least one implantable signal delivery device, the signal generator programmed with instructions that, when executed (a) direct a non-paresthesia generating electrical signal to the patient via the implantable signal delivery device for a plurality of sequential amplitude sweep periods, and (b) step the electrical signal through multiple signal amplitudes of a same polarity for individual amplitude sweep periods of the plurality of sequential amplitude sweeps periods, wherein—
at least some of the sequential amplitude sweep periods include at least some of the same multiple signal amplitudes, and
pulses of the same amplitude in sequential amplitude sweep periods have a same pulse width.
