Some embodiments provide a system for delivering neurostimulation. Some system embodiments comprise a lead configured to be implanted in the body, a stimulation output circuit configured to deliver neurostimulation pulses to the vagus nerve through the lead, an EMG sensing circuit configured to use the lead to sense EMG signals from laryngeal muscle activity, and an evoked muscular response detection circuit configured to use the EMG signals sensed by the EMG sensing circuit to detect evoked laryngeal muscle activity evoked by the neurostimulation pulse.
