Claim 11:
12. A system comprising:
a sensor configured to be implanted adjacent to an anterior lingual muscle of a subject;
an electrode configured to be implanted adjacent to a hypoglossal nerve of the subject and configured to deliver stimulation energy to the hypoglossal nerve; and
a computing device coupled to the electrode and the sensor, the computing device comprising a non-transitory, computer-readable medium storing instructions that, when executed by one or more processors of the computing device, cause the one or more processors to:
monitor EMG data recorded by the sensor over a duration of time, the EMG data characterizing activity of the anterior lingual muscle,
determine phasic activity and tonic activity of the anterior lingual muscle from the EMG data,
determine a sleep stage of the subject during one or more portions of the duration of time based on at least the tonic activity,
compare the determined sleep stage of the one or more portions of the duration of time to a previously determined sleep stage of a prior portion of the duration of time and, based on the previously determined sleep stage, determine whether to modify the determined sleep stage based on a predetermined physiological sequence of sleep stages,
determine one or more parameters of the stimulation energy based on the determined sleep stage of the subject, and
cause the electrode to deliver the stimulation energy having the one or more parameters to the hypoglossal nerve.
