First Claim
1. A method comprising:
- monitoring at least one physiological parameter of a patient via a medical device that delivers a therapy to the patient;
determining a plurality of values of a metric that is indicative of sleep quality over time based on the at least one physiological parameter;
associating each of the determined values of the sleep quality metric with a current therapy parameter set;
for each of a plurality of therapy parameter sets, determining a representative value of the sleep quality metric based on the values of the sleep quality metric associated with the therapy parameter set; and
automatically selecting one of the therapy parameter sets for delivery of the therapy based on the representative sleep quality metric values for the therapy parameter sets,wherein monitoring at least one physiological parameter comprises monitoring at least one of electrocardiogram morphology, subcutaneous temperature, muscular tone, electrical activity of a brain of the patient or eye motion.

Abstract
A medical device, such as an implantable medical device (IMD), determines values for one or more metrics that indicate the quality of a patient'"'"'s sleep, and controls delivery of a therapy based on the sleep quality metric values. For example, the medical device may compare a sleep quality metric value with one or more threshold values, and adjust the therapy based on the comparison. In some embodiments, the medical device adjusts the intensity of therapy based on the comparison, e.g., increases the therapy intensity when the comparison indicates that the patient'"'"'s sleep quality is poor. In some embodiments, the medical device automatically selects one of a plurality of therapy parameter set available for use in delivering therapy based on a comparison sleep quality metric values associated with respective therapy parameter sets within the plurality of available therapy parameter sets.
