Systems and methods provide stimulation of peripheral targets such as targets in the lower limbs. Electrode arrays realized in circumferential or longitudinal embodiments have pads with horizontal and/or vertical offsets. Electrode array geometries are customizable and adaptable to individual users and treatment of different disorders. Novel systems of customization include software and hardware implemented solutions. A single device can provide treatment of two or more disorders or unwanted states using selected electrode geometries and stimulation protocols. Systems and methods for assessment of candidate stimulation sites and protocols use subjective or objective measures or both to determine which meet stimulation success criteria. Simulation is provided using transcutaneous, percutaneous, or implantable stimulators. A main advantage is the improved treatment of pelvic floor disorders, and especially overactive bladder (OAB).
