Sensitivity analysis for selecting therapy parameter sets
First Claim
1. A method comprising:
- delivering a therapy to a patient via a medical device according to each of a plurality of therapy parameter sets, each of the parameter sets including a value for each of a plurality of therapy parameters;
monitoring a value of a performance metric of the patient in response to therapy delivered according to each of the plurality of therapy parameter sets, wherein the performance metric comprises a sleep quality metric;
conducting 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
identifying a baseline value for each of the 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.
