Closed-loop therapy adjustment
First Claim
1. A method comprising:
- sensing at least one of posture or activity of a patient via a sensor; and
,using one or more processors;
receiving a therapy adjustment from the patient via a user interface, wherein the therapy adjustment received from the patient comprises an adjustment of a value of at least one parameter of a therapy delivered by a medical device to the patient;
determining therapy information based on the therapy adjustment;
determining the at least one of posture or activity of the patient in response to the receipt of the therapy adjustment from the patient;
automatically associating the determined at least one of posture or activity of the patient with the therapy information in response to receiving the therapy adjustment;
subsequently detecting the at least one of posture or activity of the patient; and
automatically delivering therapy to the patient via the medical device according to the therapy information associated with the at least one of posture or activity of the patient in response to the subsequent detection.

Abstract
Techniques for detecting a value of a sensed patient parameter, and automatically delivering therapy to a patient according to therapy information previously associated with the detected value, are described. In exemplary embodiments, a medical device receives a therapy adjustment from the patient. In response to the adjustment, the medical device associates a sensed value of a patient parameter with therapy information determined based on the adjustment. Whenever the parameter value is subsequently detected, the medical device delivers therapy according to the associated therapy information. In this manner, the medical device may “learn” to automatically adjust therapy in the manner desired by the patient as the sensed parameter of the patient changes. Exemplary patient parameters that may be sensed for performance of the described techniques include posture, activity, heart rate, electromyography (EMG), an electroencephalogram (EEG), an electrocardiogram (ECG), temperature, respiration rate, and pH.
