ABSTRACT:
A system and method for patient control of the stimulation parameters of a Spinal Cord Stimulation (SCS) system, or other neurostimulation system, provides an increased Therapeutic Ratio (TR). Measurements of the just-perceptible stimulation level and the maximum-comfortable stimulation level are made for at least two values of pulse duration and two values of pulse amplitude. A Therapeutic Ratio is determined for stimulation level control strategies based on fixed pulse duration and variable pulse amplitude, and alternatively for fixed pulse amplitude and variable pulse duration. The control strategy providing the greatest therapeutic ratio is then selected for use by the patient. In an alternative embodiment, the pulse durations at the just-perceptible and maximum-comfortable stimulation levels are measured, and the pulse amplitudes at the just-perceptible and maximum-comfortable stimulation levels are determined using a curve-fitting process. Similarly, the pulse amplitudes may first be measured and the pulse widths determined using a curve-fitting process.
