Modification profiles for posture-responsive therapy
First Claim
1. A method comprising:
- controlling the delivery of 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 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 therapy delivered to the patient;
detecting, subsequently, a second posture state transition of the patient; and
modifying the 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 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
In general, the disclosure describes techniques for modifying therapy provided to a patient by a medical device. The techniques may be applicable to electrical stimulation therapy or other therapies. Modification of therapy may include adjustment of one or more therapy parameter values that define one or more characteristics of stimulation therapy delivered to a patient. The therapy modification may be based on activity of a patient that is detected by an IMD, such as a change in a detected posture state occupied by the patient. Different therapy modifications may be applied for different changes in detected posture state. An IMD may modify therapy based on a transition from one posture state to another posture state, and apply different modifications for different transitions. In some aspects, the modification may include a profile, such as a ramp up or ramp down in a parameter value over a period of time. The profile may be different for different posture transitions. A ramp slope may be steeper for one transition than for another transition. When a patient transitions from an upright to a lying posture state, for example, the profile may be especially abrupt. In some examples, a modification profile may define a dwell time.

41. A non-transitory computer-readable storage medium comprising instructions for causing one or more processors to:
-
control a medical device to deliver therapy to a patient according to a posture state of the patient; detect a posture state transition of the patient; modify 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 therapy delivered to the patient detect, subsequently, a second posture state transition of the patient; and modify the 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 therapy delivered to the patient that is different than the first rate of change defined by the first modification profile.
