Abstract

In general, the disclosure relates to the delivery of therapy according to a detected posture state of a patient. The disclosure contemplates a variety of techniques for managing therapy delivered to a patent, including patient and clinician interaction with a medical device configured to deliver therapy according to posture state. In one example, the disclosure relates to a technique including receiving an indication from a user indicating that at least one aspect of therapy delivered to a patient from a medical device should be suspended, wherein the at least one aspect of the therapy is delivered from the medical device to the patient according to a detected posture state of the patient; and suspending the at least one aspect of the therapy delivered from the medical device in response to receipt of the indication.

receiving an indication from a user indicating that at least one aspect of therapy delivered to a patient from a medical device should be suspended, wherein the at least one aspect of the therapy is delivered from the medical device to the patient according to a detected posture state of the patient;

controlling, via one or more processors, the medical device to suspend the at least one aspect of the therapy delivered from the medical device in response to receipt of the indication; and

controlling the medical device to deliver therapy to the patient not according to the detected posture state of the patient during at least a portion of time the at least one aspect of the therapy is suspended.

2. The method of claim 1, wherein the therapy comprises electrical stimulation therapy.

3. The method of claim 2, wherein the at least one aspect of the stimulation therapy comprises at least one stimulation therapy group.

4. The method of claim 1, wherein the user comprises the patient, and wherein receiving the indication from the user comprises receiving an indication via a user interface.

5. The method of claim 1, wherein all aspects of the therapy delivered according to the detected posture state of the patient are suspended in response to the indication.

6. The method of claim 1, wherein controlling the medical device to suspend the at least one aspect of the therapy comprises controlling the medical device to suspend less than all aspects of the therapy that are delivered according to the detected posture state of the patient.

7. The method of claim 1, further comprising controlling the medical device to resume the at least one aspect of therapy that was suspended.

8. The method of claim 7, further comprising receiving an indication from the user that at least one aspect of the therapy should be resumed, and wherein controlling the medical device to resume the at least one aspect of the therapy comprises resuming the at least one aspect of the therapy based on the receipt of the indication that the therapy should be resumed.

9. The method of claim 7, wherein controlling the medical device to resume the at least one aspect of the therapy comprises controlling the medical device to resume the at least one aspect of the therapy based at least in part upon expiration of a time period.

10. The method of claim 1, further comprising detecting the posture state of the patient while suspending the at least one aspect of the therapy.
