1. A method comprising:
- applying, via one or more electrodes, stimulation therapy to a patient according to a set of stimulation therapy parameters;
detecting, using at least one electrode of the one or more electrodes used for applying the stimulation therapy to the patient, a signal including an evoked compound muscle action potential (eCMAP) in response to the application of the stimulation therapy;
detecting, using a posture state module, a posture state of the patient; and
adjusting, by a processor, one or more stimulation therapy parameters of the set of stimulation therapy parameters based on the detected signal and the detected posture state.

Abstract
An example system includes a stimulation generator configured to deliver electrical stimulation therapy to tissue of a patient in accordance with a stimulation therapy program. The stimulation therapy program may include a set of stimulation therapy parameters. The system may include at least one sensor configured to detect a signal including an evoked compound muscle action potential (eCMAP) in response to the application of stimulation according to the stimulation therapy program. The system may also include a processor configured to adjust one or more or the stimulation therapy parameters based on the detected signal that includes the eCMAP.
