Methods and systems for obtaining and analyzing electromyography responses of electrodes of an implanted neurostimulation lead for use neurostimulation programming are provided herein. System setups for neural localization and/or programming include a clinician programmer coupleable with a temporary or permanent lead implantable in a patient and at least one pair of EMG sensing electrodes minimally invasively positioned on a skin surface or within the patient. The clinician programmer is configured to determine a plurality of recommended electrode configurations based on thresholds and EMG responses of the plurality of electrodes and rank the electrode configuration according to pre-determined criteria. The clinician programmer further includes graphical user interface on which the plurality of recommended electrode configurations are displayed for modification and/or selection by a clinician in programming an IPG or EPG coupled with the lead to apply a neurostimulation treatment according to the selected electrode configuration.

A method of programming a neurostimulation device coupleable with a plurality of electrodes of a neurostimulation lead implanted near a target nerve, the method comprising: obtaining a stimulation threshold for each of the plurality of electrodes with a clinician programming device, wherein the stimulation threshold is based, at least in part, on a first electromyographic (EMG) recording of at least one neuromuscular response during stimulation of a given electrode of the plurality of electrodes;generating a plurality of electrode configurations of the plurality of electrodes for use in therapy based, at least in part, on the stimulation thresholds obtained by the clinician programming device;identifying a plurality of neurostimulation programs corresponding to the plurality of electrode configurations of the plurality of electrodes of the lead based, at least in part, on the stimulation thresholds obtained by the clinician programming device;applying the plurality of identified neurostimulation programs with the clinician programming device and recording at least a second EMG response of at least one neuromuscular response during applying each of the plurality of identified neurostimulation programs with the clinician programming device;determining a first neurostimulation program based on the plurality of identified neurostimulation programs applied with the clinician programming device based, at least in part, on the second EMG response and selecting the first neurostimulation program for application as a current therapy with the neurostimulation device; andprogramming the neurostimulation device with the clinician programming device with the first neurostimulation program as a current therapy. 2. The method of claim 1, wherein the applying the plurality of identified neurostimulation programs and recording at least a second EMG response comprises applying sub-threshold stimulation with the plurality of electrodes. 3. The method of claim 2, wherein determining the first neurostimulation therapy program from the plurality of neurostimulation programs comprises adjusting parameters of one neurostimulation program of the plurality of neurostimulation programs based on the at least a second EMG recording of a big toe response to stimulation lower than that required to elicit an outwardly visible big toe movement. 4. The method of claim 2, wherein recording the at least a second EMG response comprises recording an EMG of only a single neuromuscular response. 5. The method of claim 4, wherein the target nerve comprises a sacral nerve and the single neuromuscular response is a big toe response or an anal bellows response. 6. The method of claim 5, wherein the single neuromuscular response is the big toe response. 7.

The method of claim 1, wherein the stimulation thresholds obtained are previously recorded stimulation thresholds determined by the clinician programming device during placement of the lead. 9. The method of claim 1, wherein the stimulation thresholds are determined by the clinician programming device after placement of the lead. 10. The method of claim 1, wherein the clinician programming device is directly electrically coupled to the plurality of electrodes of the lead during programming via input ports of the clinician programming device. 11. The method of claim 1, wherein the clinician programming device includes a graphical user interface display, the method further comprising: recording the at least a second EMG response with the clinician programming device; andoutputting user feedback as to an electrode configuration of the plurality of electrodes based on the determined stimulation thresholds. 12.
