Collecting activity information to evaluate therapy
First Claim
1. A medical system comprising:
- an implantable medical device that that delivers a therapy to a patient, monitors a signal that varies as a function of patient activity, periodically determines an activity level of the patient based on the signal, and associates each of the determined activity levels with a therapy parameter set that was used by the implantable medical device to deliver the therapy to the patient when the activity level was determined; and
an external programming device including a display that is configured to receive information identifying a plurality of therapy parameter sets and associated activity levels from the implantable medical device via telemetry, determine a value of an activity metric for each of a plurality of therapy parameter sets based on activity levels associated with the therapy parameter sets, and present a list of the plurality of therapy parameter sets and activity metric values associated with the therapy parameter sets via the display.

Abstract
A medical device delivers a therapy to a patient. The medical device may periodically determine an activity level of the patient, and associate each determined activity level with a current therapy parameter set. A value of at least one activity metric is determined for each of a plurality of therapy parameter sets based on the activity levels associated with that therapy parameter set. A list of the therapy parameter sets is presented to a user, such as a clinician, for evaluation of the relative efficacy of the therapy parameter sets. The list may be ordered according to the one or more activity metric values to aid in evaluation of the therapy parameter sets. Where values are determined for a plurality of activity metrics, the list may be ordered according to the one of the activity metrics selected by the user.

14. A programming device comprising:
-
a telemetry circuit; a user interface including a display; and a processor that is configured to receive information identifying a plurality of therapy parameter sets and activity levels associated with the therapy parameter sets from an implantable medical device via the telemetry circuit, determine a value of an activity metric for each of a plurality of therapy parameter sets based on activity levels associated with the therapy parameter sets, and present a list of the plurality of therapy parameter sets and activity metric values associated with the therapy parameter sets via the display, wherein each activity level of the activity levels associated with the therapy parameter sets is associated with a therapy parameter set that was used by the implantable medical device to deliver a therapy to a patient when the activity level was determined. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
