Collecting posture information to evaluate therapy
First Claim
1. A method comprising:
- monitoring at least one signal generated by a sensor as a function of at least one of activity or posture of a patient during delivery of a therapy to a patient from a medical device according to therapy parameters that change over time according to a plurality of therapy parameter sets;
periodically identifying a posture of the patient based on the at least one signal;
for each therapy parameter set in the plurality of therapy parameter sets, associating each of the identified postures that occurred during the delivery of the therapy to the patient according to that individual therapy parameter set with that individual therapy parameter set; and
for each therapy parameter set in the plurality of therapy parameter sets, displaying for a user the postures identified during the delivery of the therapy to the patient according to that individual therapy parameter set in a manner that is indicative of efficacy of that individual therapy parameter set.

Abstract
A medical device delivers a therapy to a patient. Posture events are identified, e.g., a posture of the patient is periodically determined and/or posture transitions by the patient are identified, and each determined posture event is associated with a current therapy parameter set. A value of at least one posture metric is determined for each of a plurality of therapy parameter sets based on the posture events 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 posture metric values to aid in evaluation of the therapy parameter sets. Where values are determined for a plurality of posture metrics, the list may be ordered according to the one of the posture metrics selected by the user.

25. A medical system comprising:
-
means for monitoring at least one signal generated by a sensor as a function of at least one of activity or posture of a patient during delivery of a therapy to a patient from a medical device according to therapy parameters that change over time according to a plurality of therapy parameter sets; means for periodically identifying a posture of the patient based on the at least one signal; means for associating each of the identified postures with the therapy parameter set of the plurality of therapy parameter sets that was used by the medical device to deliver the therapy to the patient when the posture was identified; and means for displaying for a user the postures associated with each of the therapy parameter sets in a manner that is indicative of efficacy of each of the therapy parameter sets.
