Collecting activity and sleep quality information via a medical device
First Claim
1. A method comprising:
- monitoring a plurality of physiological parameters of a patient, wherein the plurality of physiological parameters includes at least one parameter indicative of patient physical activity;
determining when the patient is attempting to sleep;
determining values of at least one metric that is indicative of sleep quality based on at least one of the physiological parameters and a determination that the patient is attempting to sleep; and
periodically determining an activity level of the patient based on at least one of the physiological parameters and a determination that the patient is not attempting to sleep, wherein monitoring a plurality of physiological parameters comprises monitoring at least one of electrocardiogram morphology, subcutaneous temperature, muscular tone, brain electrical activity, or eye motion.

Abstract
A device, such as an implantable medical device (IMD), programming device, or other computing device determines when a patient is attempting to sleep. When the device determines that the patient is attempting to sleep, the device determines values for one or more metrics that indicate the quality of a patient'"'"'s sleep based on at least one physiological parameter of the patient. When the device determines that the patient is not attempting to sleep, the device periodically determines activity levels of the patient. Activity metric values may be determined based on the determined activity levels. A clinician may use sleep quality information and patient activity information presented by a programming device to, for example, evaluate the effectiveness of therapy delivered to the patient by a medical device.
