Collecting activity information to evaluate therapy
First Claim
1. A method comprising:
- monitoring a signal that varies as a function of patient activity;
periodically determining an activity level of the patient based on the signal;
associating each of the determined activity levels with a therapy parameter set currently used by a medical device to deliver a therapy to a the patient when the activity level is was determined, wherein the therapy comprises at least one of a movement disorder therapy, psychological disorder therapy, or deep brain stimulation; and
determining 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.

Abstract
A medical device delivers a therapy to a patient. The medical device or another 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.
