POSTURE STATE CLASSIFICATION FOR A MEDICAL DEVICE
First Claim
1. A system, comprising:
- a sensor to provide a signal indicative of a posture state of a patient;
a processor adapted to determine based on the signal whether the posture state of the patient is stable, and if so, to create an association between the posture state and a corresponding therapy parameter value; and
a memory to store the association.

Abstract
Techniques relate to operating a medical device in response to a detected posture state of a patient. A trigger event such as a request to modify how therapy is being delivered to the patient may cause a determination to be made as to whether the patient'"'"'s posture state is stable. If the posture state is stable, an association is created between the posture state and one or more therapy parameter values. Over time, a library of such associations is created that may reflect any posture state in three dimensional space, wherein a posture state comprises at least one of a posture and an activity component. The library of associations may be used to automatically control therapy delivery. Similar ones of the associations may automatically be grouped into posture state regions to facilitate more efficient classification of the patient'"'"'s posture state to control therapy delivery.

21. A method, comprising:
-
obtaining an indication of a posture state; determining, with a processor, whether the indication indicates a patient is in a stable posture state; and if the patient is in a stable posture state, storing an association between the posture state and at least one therapy parameter value. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)

42. An article of manufacture comprising a computer-readable medium storing executable instructions to cause a processor to:
-
obtain a parameter indicative of a posture state; determine whether the parameter indicates a patient is in a stable posture state; and if the patient is in a stable posture state, create an association between the posture state and at least one therapy parameter value used to control delivery of therapy to the patient. - View Dependent Claims (43, 44, 45, 46)

47. A system, comprising:
-
processor means for obtaining at least one indication of a posture state of a patient, for determining whether the at least one posture state is stable, and for creating an association between each stable posture state and a corresponding therapy parameter value; and memory means for storing the association between each stable posture state and a corresponding therapy parameter value.
