Associating therapy adjustments with posture states using a stability timer
First Claim
Patent Images
1. A method comprising:
- detecting an adjustment to one or more parameters of electrical stimulation therapy delivered to a patient;
sensing a posture state of the patient; and
associating, by a processor, the detected adjustment with the sensed posture state when the sensed posture state does not change within a period of time subsequent to the detected adjustment, wherein the period of time is tracked by a single timer.

Abstract
The disclosure describes techniques for associating therapy adjustments with posture states using a timer. The techniques may include detecting a patient adjustment to electrical stimulation therapy delivered to the patient, sensing a posture state of the patient, and associating the detected adjustment with the sensed posture state if the sensed posture state is sensed within a first period following the detection of the adjustment and if the sensed posture state does not change during a second period following the sensing of the sensed posture state.
