1. A medical system of measuring a physiological feedback from a patient in response to electrical stimulation, comprising:

  • an anal electrode device that is configured to be inserted into an anal canal of a patient, wherein the anal electrode device is configured to measure a compound motor action potential (CMAP) from an anal sphincter of the patient while a sacral nerve stimulation therapy is delivered to the patient;

    a stimulation lead having a plurality of electrode contacts, wherein the stimulation lead is implantable inside the patient;

    a pulse generator electrically coupled to the stimulation lead, wherein the pulse generator is configured to generate electrical pulses of the sacral nerve stimulation therapy to be delivered by one or more of the electrode contacts to the patient; and

    an electronic programmer telecommunicatively coupled to the pulse generator, wherein the electronic programmer is configured to program the pulse generator to generate the electrical pulses, and wherein the electronic programmer is configured to;

    ramp up a stimulation parameter of the sacral nerve stimulation therapy;

    receive measurements of the CMAP as the stimulation parameter of the sacral nerve stimulation therapy is being ramped up; and

    determine a stimulation threshold based on the received measurements of the CMAP.
