SENSITIVITY ANALYSIS FOR SELECTING THERAPY PARAMETER SETS
First Claim
1. A computer-readable medium comprising instructions that cause a programmable processor to:
- monitor a value of a performance metric of a patient for each of a plurality of therapy parameter sets, wherein a medical device delivers a therapy to the patient according to each of the therapy parameter sets, each of the therapy parameter sets includes a value for each of a plurality of therapy parameters, and the performance metric comprises a sleep quality metric;
conduct a sensitivity analysis of the performance metric for each of the plurality of therapy parameters based on the monitored values of the performance metric; and
identify a baseline value for each of the plurality of therapy parameters based on the sensitivity analysis to form a baseline therapy parameter set.

Abstract
Techniques for controlling delivery of a therapy to a patient by a medical device, such as an implantable medical device (IMD), involve a sensitivity analysis of a performance metric. The performance metric may relate to efficacy or side effects of the therapy. For example, the performance metric may comprise a sleep quality metric, an activity level metric, a movement disorder metric for patients with Parkinson'"'"'s disease, or the like. The sensitivity analysis identifies values of therapy parameters that defines a substantially maximum or minimum value of the performance metric. The identified therapy parameters are a baseline therapy parameter set, and a medical device may control delivery of the therapy based on the baseline therapy parameter set.

5. A system comprising:
-
a therapy device that delivers a therapy to a patient according to each of a plurality of therapy parameter sets, each of the therapy parameter sets including a value for each of a plurality of therapy parameters; a monitor that monitors values of at least one physiological parameter of a patient during delivery of therapy according to each of the plurality of therapy parameter sets; and a computing device that receives the physiological parameter values from the monitor, identifies a value of a performance metric of the patient for each of the plurality of parameter sets based on the physiological parameter values monitored during delivery of therapy according to each of the plurality of therapy parameter sets, conducts a sensitivity analysis of the performance metric for each of the plurality of therapy parameters based on the monitored values of the performance metric, and identifies a baseline value for each of the therapy parameters based on the sensitivity analysis to form a baseline therapy parameter set. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
