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 via a medical device, wherein the plurality of physiological parameters includes at least one parameter indicative of patient physical activity monitored via at least one accelerometer;
determining when the patient is attempting to sleep;
determining when the patient is asleep based on at least one of the physiological parameters;
determining values of at least one sleep quality metric that is indicative of sleep quality based on at least one of when the patient is attempting to sleep, when the patient is asleep, or values of at least one of the physiological parameters when the patient is asleep;
periodically determining an activity level of the patient based on the at least one of the physiological parameters indicative of patient physical activity that is monitored via the at least one accelerometer; and
determining a value of at least one activity metric based on activity levels determined when the patient is not attempting to sleep.

Abstract
A device, such as an implantable medical device (IMD) or a programming 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 the medical device.
