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. In one example, the disclosure relates to a technique including delivering therapy to a patient from a medical device, wherein the therapy is delivered to the patient according to a detected posture state of the patient; and automatically adjusting at least one aspect of the therapy delivered from a medical device based at least in part on one or more of time or patient posture state behavior, wherein automatically adjusting at least one aspect of therapy comprises suspending at least one aspect of the therapy or decreasing a posture state detection frequency

Claims

1. A method comprising:

delivering therapy to a patient from a medical device, wherein the therapy is delivered to the patient according to a detected posture state of the patient; and

automatically adjusting at least one aspect of the therapy delivered from a medical device based at least in part on one or more of time or patient posture state behavior,

wherein automatically adjusting at least one aspect of therapy comprises suspending at least one aspect of the therapy or decreasing a posture state detection frequency.

2. The method of claim 1, wherein suspending at least one aspect of the therapy comprises suspending posture state detection.

3. The method of claim 1, wherein suspending at least one aspect of the therapy comprises suspending delivery of therapy to the patient but not suspending posture state detection.

4. The method of claim 1, wherein suspending at least one aspect of the therapy comprises suspending all delivery of therapy to the patient.

5. The method of claim 1, further comprising:

determining the time; and

comparing the determined time to automatic adjustment time information,

wherein automatically adjusting at least one aspect of the therapy delivered from a medical device based at least in part on time comprises automatically adjusting at least one aspect of the therapy delivered from a medical device based at least in part on the comparison of the determined time to the automatic adjustment time information.

6. The method of claim 5, wherein the automatic adjustment time information comprises one or more automatic adjustment time periods.

7. The method of claim 1, further comprising:

determining an amount of time the patient has occupied a current posture state; and

comparing the amount of time the patient has occupied a current posture state to automatic adjustment time information,

wherein automatically adjusting at least one aspect of the therapy delivered from a medical device based at least in part on patient posture state behavior comprises automatically adjusting at least one aspect of the therapy delivered from a medical device based at least in part on the comparison to the amount of time the patient has occupied a current posture state to the automatic adjustment time information.

8. The method of claim 7, wherein the current posture state comprises a plurality of individual posture states.

9. The method of claim 1, wherein automatically adjusting at least one aspect of therapy further comprises resuming at least one aspect of the therapy or increasing a posture state detection frequency.

10. The method of claim 1, further comprising:

monitoring one or more posture sensor signal outputs; and

automatically increasing the detection frequency based on the one or more posture sensor signal outputs.

11. The method of claim 1, wherein decreasing the posture state detection frequency comprises decreasing one or more of a posture sensor sampling frequency or posture state calculation frequency.

12. A system comprising:

a therapy delivery module configured to deliver therapy to a patient;

a timing unit configured to determine time; and

a processor configured to control the therapy module to deliver therapy to the patient according to a detected posture state of the patient, and automatically adjust at least one aspect of the therapy delivered from a medical device based at least in part on one or more of time or patient posture state behavior,

wherein the processor at least one of suspends at least one aspect of the therapy or decreases a posture state detection frequency to automatically adjust the at least one aspect of the therapy.

13. The system of claim 12, wherein the processor in configured to suspend posture state detection to suspend the at least one aspect of the therapy.

14. The system of claim 12, wherein the processor suspends delivery of therapy to the patient but does not suspend posture state detection to suspend the at least one aspect of the therapy.

15. The system of claim 12, wherein the processor suspends all delivery of therapy to the patient to suspend the at least one aspect of the therapy.

16. The system of claim 12, wherein the processor is configured to compare the time determined via the timing unit to automatic adjustment time information, and automatically adjusts at least one aspect of the therapy delivered from a medical device based at least in part on the comparison of the determined time to the automatic adjustment time information.

17. The system of claim 16, wherein the automatic adjustment time information comprises one or more automatic adjustment time periods.

18. The system of claim 12, wherein the processor is further configured to determine an amount of time the patient has occupied a current posture state, compare the amount of time the patient has occupied a current posture state to automatic adjustment time information, and automatically adjust at least one aspect of the therapy delivered from a medical device based at least in part on the comparison.

19. The system of claim 18, wherein the current posture state comprises a plurality of individual posture states.

20. The system of claim 12, wherein the processor resumes at least one aspect of the therapy or increases a posture state detection frequency to automatically adjust at least one aspect of the therapy.

21. The system of claim 12, wherein the processor is configured to monitor one or more posture sensor signal outputs, and automatically increase the detection frequency based on the one or more posture state signal outputs.

22. The system of claim 12, the processor is configured to decrease one or more of a posture sensor sampling frequency or posture state calculation frequency to decrease the posture state detection frequency.

23. A system comprising:

means for delivering therapy to a patient from a medical device, wherein the therapy is delivered to the patient according to a detected posture state of the patient; and

means for automatically adjusting at least one aspect of the therapy delivered from a medical device based at least in part on one or more of time or patient posture state behavior,

wherein automatically adjusting at least one aspect of therapy comprises suspending at least one aspect of the therapy or decreasing a posture state detection frequency.

24. A computer-readable storage medium comprising instructions for causing one or more processors to:

deliver therapy to a patient from a medical device, wherein the therapy is delivered to the patient according to a detected posture state of the patient; and

automatically adjust at least one aspect of the therapy delivered from a medical device based at least in part on one or more of time or patient posture state behavior,

wherein the instructions may cause the one or more processor to suspend the at least one aspect of the therapy or decrease a posture state detection frequency to automatically adjust at least one aspect of the therapy.
