Programming posture responsive therapy
First Claim
1. A method comprising:
- controlling the delivery of electrical neurostimulation therapy to a patient from a medical device according to a posture state of the patient;
detecting a first posture state transition of the patient;
modifying, based on the detection of the first posture state transition, the electrical neurostimulation therapy according to a first modification profile defined for the first posture state transition, wherein the first modification profile defines a first rate of change for an adjustment of at least one parameter of the therapy delivered to the patient;
detecting, subsequently, a second posture state transition of the patient; and
modifying, based on the detection of the second posture state transition, the electrical neurostimulation therapy according to a second modification profile defined for the second posture state transition, wherein the second modification profile defines a second rate of change for an adjustment of the at least one parameter of the electrical neurostimulation therapy delivered to the patient that is different than the first rate of change defined by the first modification profile, andwherein at least one of the controlling, detecting, determining, and modifying are performed via one or more processors.

Abstract
A programming session for an implantable medical device that includes a posture responsive therapy mode includes at least two phases. In a first phase, a first set of therapy parameter values are modified while the posture responsive therapy mode is deactivated. In the posture responsive therapy mode, the medical device automatically selects one or more therapy parameter values that define therapy delivered to a patient based on a detected posture state. In a second phase, the posture responsive therapy mode is activated and a second set of therapy parameter values are adjusted after observing a patient response to the posture responsive therapy delivered with the first set of therapy parameter values selected during the first phase. The second set of therapy parameter values may, for example, define the patient posture states or the modification profiles with which the medical device adjusts therapy upon detecting a posture state transition.

12. A therapy system comprising:
-
a therapy delivery module configured to deliver electrical neurostimulation therapy to a patient from a medical device; and at least one processor configured to control the delivery of the electrical neurostimulation therapy to the patient from the medical device according to a posture state of the patient, detect a first posture state transition of the patient, modify, based on the detection of the first posture state transition, the therapy according to a first modification profile defined for the first posture state transition, wherein the first modification profile defines a first rate of change for an adjustment of at least one parameter of the electrical neurostimulation therapy delivered to the patient, detect, subsequently, a second posture state transition of the patient, and modify, based on the detection of the second posture state transition, the electrical neurostimulation therapy according to a second modification profile defined for the second posture state transition, wherein the second modification profile defines a second rate of change for an adjustment of the at least one parameter of the electrical neurostimulation therapy delivered to the patient that is different than the first rate of change defined by the first modification profile. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
