Abstract:
1. A non-transient computer-readable medium storing a software application executable by a processor and comprising instructions that, when executed by the processor, cause the following functions to be performed: (a) deliver a plurality of stimulation current signals to tissue including or adjacent to a spinal nerve, (b) in response to delivery of each one of the plurality of stimulation current signals, receive a plurality of voltage response values detected by a plurality of leg muscle sensor electrodes coupled to different leg muscles, (c) determine the value of an unknown threshold nerve stimulation current amplitude required to evoke a threshold voltage response from at least one of the leg muscles using the steps of: (d) determine which range from a predetermined group of ranges the determined threshold nerve stimulation current amplitude is located in; and (e) display the determined threshold nerve stimulation current amplitude in units of mA on a display device along with a color-coded indicator corresponding to the determined range from the predetermined group of ranges.
