1. A method for providing sub-perception stimulation to a patient having an implantable spinal cord stimulator comprising a plurality of electrodes in an electrode array, the method comprising in order:
programming a first amplitude for the implantable spinal cord stimulator;
providing supra-perception biphasic stimulation pulses at a frequency via one or more first of the plurality of electrodes and one or more second of the plurality of electrodes, wherein the supra-perception biphasic stimulation pulses have first and second phases,
wherein during the first phases the one or more first electrodes provide the first amplitude in sum as an anodic current and the one or more second electrodes provide the first amplitude in sum as a cathodic current,
wherein during the second phases the one or more second electrodes provide the first amplitude in sum as an anodic current and the one or more first electrodes provide the first amplitude in sum as a cathodic current;
programming a second amplitude for the implantable spinal cord stimulator, wherein the second amplitude is lower than the first amplitude;
providing sub-perception biphasic stimulation pulses at the frequency via the one or more first electrodes and the one or more second electrodes, wherein the sub-perception biphasic stimulation pulses have third and fourth phases,
wherein during the third phases the one or more first electrodes provide the second amplitude in sum as an anodic current and the one or more second electrodes provide the second amplitude in sum as a cathodic current, and
wherein during the fourth phases the one or more second electrodes provide the second amplitude in sum as an anodic current and the one or more first electrodes provide the second amplitude in sum as a cathodic current.
