1. A system for stimulating tissue, the system comprising:
at least one sensor configured to measure one or more physiological parameters of a body;
user interface; a stimulation array including at least two electrode assemblies; and
a control unit including a processor and a non-transitory computer readable medium storing instructions that, when executed by the processor, cause the processor to identify an electrode combination and determine a threshold charge for stimulating tissue;
wherein identifying the electrode combination includes:
selecting a set of electrode combinations;
stimulating from each electrode combination of the set of electrode combinations; and
for each stimulation from an electrode combination, receiving an input via the at least one sensor or the user interface, the input corresponding to whether a first requisite stimulation was detected from the stimulation; and
wherein determining the threshold charge for stimulating tissue includes:
performing an electrode sweep at a first charge;
receiving an input via the at least one sensor or the user interface, the input corresponding to whether a second requisite stimulation was detected from the electrode sweep at the first charge; and
either (a) setting a coarse threshold charge at a charge of the most recent electrode sweep, based on the second requisite stimulation being detected; or (b) performing an electrode sweep at a second charge greater than the first charge, based on the second requisite stimulation not being detected;
wherein identifying an electrode combination includes identifying an electrode combination for each electrode assembly; and
identifying a threshold charge includes identifying a threshold charge for each electrode assembly.
