Automatic therapy adjustments
First Claim
1. A method comprising:
- monitoring an output of a sensor, the output of the sensor reflecting a physiological parameter of a patient;
initially defining an event based on the monitoring of the sensor output, wherein initially defining the event comprises storing an indication of the monitored sensor output within a memory as the defined event;
monitoring therapy delivered by a medical device while the output of the sensor was monitored during the event to initially define the event;
generating therapy information based on the monitoring of the therapy while the output of the sensor was monitored during the event to initially define the event;
associating the therapy information with the defined event within the memory;
subsequently detecting the defined event by monitoring the output of the sensor and comparing the sensor output to the defined event; and
automatically providing therapy to the patient via the medical device according to the therapy information associated with the defined event in response to the detection.

Abstract
A medical device detects a previously defined event, and controls delivery of therapy to a patient according to therapy information associated with the previously defined event. In exemplary embodiments, the medical device enters a learning mode in response to a command received from a user, e.g., the patient or a clinician. In such embodiments, the medical device defines the event, collects the therapy information, and associates the therapy information with the defined event while operating in the learning mode. In some embodiments, the medical device defines the event based on the output of a sensor that indicates a physiological parameter of the patient during the learning mode. The sensor may be an accelerometer, which generates an output that reflects motion and/or posture of the patient. The medical device may collect therapy information by recording therapy changes made by the user during the learning mode.
