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…
