Collecting posture information to evaluate therapy
First Claim
1. A medical system comprising:
- a medical device that delivers a therapy to a patient according to therapy parameters that change over time according to a plurality of therapy parameter sets;
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 during the delivery of the therapy to the patient,identifies 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, associates each of the movement events in the plurality of movement events that occur during the delivery of the therapy to the patient according that individual therapy parameter set with that individual therapy parameter set, and,for each therapy parameter set in the plurality of therapy parameter sets, determines a value of a metric based on the movement events associated with that individual therapy parameter set, wherein the value of the metric indicates an 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.

11. A medical system comprising:
-
means for delivering a therapy to a patient according to therapy parameters that change over time according to a plurality of therapy parameter sets; means for monitoring a signal generated by a sensor as a function of movement of a patient during the delivery of the therapy to the patient; means for identifying a plurality of movement events based on the signal during the delivery of the therapy to the patient; means for associating, for each therapy parameter set in the plurality of therapy parameter sets each of the movement events in the plurality of movement events that occur during the delivery of the therapy to the patient according that individual therapy parameter set with that individual therapy parameter set; and means for determining, for each therapy parameter set in the plurality of therapy parameter sets, a value of a metric based on the movement events associated with that individual therapy parameter set, wherein the value of the metric indicates an efficacy of that individual therapy parameter set. - View Dependent Claims (12)
