Collecting posture information to evaluate therapy
First Claim
1. A method for evaluating therapy comprising:
- monitoring, with a processor, a signal generated by a sensor as a function of movement of a patient during the delivery of a therapy to the patient by a medical device that delivers the therapy to the patient according to therapy parameters that change over time according to a plurality of therapy parameter sets;
identifying a plurality of movement events based on the signal during the delivery of the therapy to the patient;
for each therapy parameter set in the plurality of therapy parameter sets, associating each of the movement events in the plurality of movement events that occur during the delivery of the therapy to the patient according to that particular therapy parameter set with that particular therapy parameter set;
for each therapy parameter set in the plurality of therapy parameter sets, determining a value of a metric based on the movement events associated with that particular therapy parameter set, the value of the metric indicating an efficacy of that particular therapy parameter set; and
storing, for each therapy parameter set in the plurality of therapy parameter sets, the value of the metric based on the movement events associated with that particular therapy parameter set in a computer-readable memory.

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.

18. A method for evaluating therapy comprising:
-
monitoring, with a processor, 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; 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; and storing, for each therapy parameter set in the plurality of therapy parameter sets, the value of the metric based on the movement events associated with that particular therapy parameter set in a computer-readable memory. - View Dependent Claims (19, 22)
