COLLECTING POSTURE INFORMATION TO EVALUATE THERAPY
First Claim
1. A method for evaluating therapy comprising:
- monitoring a signal generated by a sensor as a function of movement of a patient;
identifying a plurality of movement events based on the signal;
associating each of the movement events with a therapy parameter set that was used by a medical device to deliver a therapy to the patient when the movement event was identified; and
for each of a plurality of therapy parameter sets, determining a value of a metric based on the movement events associated with the therapy parameter set, the value of the metric indicating an efficacy of the 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.

11. A medical system comprising:
-
a medical device that delivers a therapy to a patient; a sensor that generates a signal as a function of movement of the patient; and a processor that monitors the signal generated by the sensor, identifies a plurality of movement events based on the signal, associates each of the movement events with a therapy parameter set that was used by the medical device to deliver the therapy to the patient when the movement event was identified, and, for each of a plurality of therapy parameter sets, determines a value of a metric based on the movement events associated with the therapy parameter set. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A medical system comprising:
-
means for delivering a therapy to a patient; means for monitoring a signal generated by a sensor as a function of movement of a patient; means for identifying a plurality of movement events based on the signal; means for associating each of the movement events with a therapy parameter set that was used by the means for delivering to deliver the therapy to the patient when the activity level was determined; and means for determining, for each of a plurality of therapy parameter sets, a value of a metric based on the movement events associated with the therapy parameter set.
