Abstract: In some examples, the disclosure relates to system, devices, and techniques for delivering electrical stimulation therapy to treat patient disorders. In some example, the disclosure is directed to a method including controlling, using processing circuitry, the delivery of an electrical stimulation therapy to a patient via a medical device, wherein the electrical stimulation therapy includes a plurality of bi-phasic pulses, each pulse of the di¬phasic pulses including a first phase followed by a second phase, and wherein the plurality 7 of bi-phasic pulses are configured to substantially block transmission of neural activity? along nerve fibers.
