1. A system comprising:
- at least one physical computing device configured todirect an implantable stimulator to sequentially present a plurality of substantially identical stimulation events to a patient;
record a plurality of electromyography (“
EMG”
) signals generated by a muscle in the patient and each corresponding to a presentation of a particular stimulation event included in the plurality of substantially identical stimulation events;
determine an asynchronous component of each of the recorded EMG signals, the asynchronous components of the recorded EMG signals each being unsynchronized with the sequential presentation of the stimulation events;
determine an amount of energy contained within each of a plurality of phases of each of the asynchronous components;
analyze the amounts of energy contained within each of the plurality of phases of each of the asynchronous components; and
determine, based on the analysis of the amounts of energy, whether an EMG response is evoked by the stimulation events.

Abstract
An exemplary EMG response detection system may be configured to 1) direct an implantable stimulator to sequentially present a plurality of substantially identical stimulation events to a patient, 2) record a plurality of EMG signals generated by a muscle in the patient and each corresponding to a presentation of a particular stimulation event included in the plurality of substantially identical stimulation events, 3) determine an asynchronous component of each of the recorded EMG signals, and 4) utilize the asynchronous components of the recorded EMG signals to determine whether an EMG response is evoked by the stimulation events.

16. A method comprising:
-
directing, by an electromyography (“
EMG”
) response detection system, an implantable stimulator to sequentially present a plurality of substantially identical stimulation events to a patient;recording, by the EMG response detection system, a plurality of EMG signals generated by a muscle in the patient and each corresponding to a distinct stimulation event included in the plurality of substantially identical stimulation events; determining, by the EMG response detection system, an asynchronous component of each of the recorded EMG signals, the asynchronous components of the recorded EMG signals each being unsynchronized with the sequential presentation of the stimulation events; determining, by the EMG response detection system, an amount of energy contained within each of a plurality of phases of each of the asynchronous components; analyzing, by the EMG response detection system, the amounts of energy contained within each of the plurality of phases of each of the asynchronous components; and determining, by the EMG response detection system based on the analysis of the amounts of energy, whether an EMG response is evoked by the stimulation events. - View Dependent Claims (17, 18, 19, 20)
