Abstract

The disclosure provides a system that displays an indicator of patient posture state that changes according to posture state data. The posture state data may be transmitted from a medical device, for example, in or near real-time. In some examples, the disclosure relates to a method comprising receiving posture state data for a patient from a medical device; and presenting an indicator indicative of two or more of posture states based on the received posture state data, wherein each posture state of the two or more posture states is determined based on different detection criteria.

Claims

1. A method comprising:

receiving posture state data for a patient from a medical device;

determining a first posture state of the patient at a time based on the posture state data using a first detection criteria;

determining a second posture state of the patient at the time based on the posture state data using a second detection criteria different from the first detection criteria; and

presenting an indicator indicative of the determined first posture state and second posture state,

wherein at least one of the receiving, determining the first posture state, determining the second posture state, and presenting is performed by at least one processor.

2. The method of claim 1, wherein the first posture state and second posture state include at least one of real-time patient posture state, asserted patient posture state, and stable patient posture state.

3. The method of claim 1, wherein the medical device is configured to deliver therapy to the patient.

4. The method of claim 1, wherein presenting the indicator comprises presenting one or more graphical representations representative of the first posture state and the second posture state.

5. The method of claim 1, wherein the received posture state data is transmitted from the medical device in real-time or near real-time with generation of the posture state data.

6. The method of claim 1, further comprising presenting at least one of a posture state text, an activity level, and a raw signal data graph based upon the posture state data.

7. The method of claim 1, wherein presenting an indicator indicative of the determined first posture state and second posture state comprises presenting a stable posture state indication indicative of a stable posture state used by the medical device to deliver therapy and presenting an unstable posture state indication indicative of an unstable posture state not used by the medical device to delivery therapy.

8. The method of claim 7, wherein the unstable posture state comprises at least one of a real-time posture state or asserted posture state.

9. The method of claim 1, wherein receiving posture state data for the patient from the medical device comprises receiving posture state data for the patient from the medical device at a stream rate between about 1 Hz and about 3 Hz.

10. The method of claim 1, wherein the indicator indicative of the determined first posture state and second posture state is at least one of an upright posture state indicator, a reclining posture state indicator, a lying back posture state indicator, a lying front posture state indicator, a lying left posture state indicator, a lying right posture state indicator, a running posture state indicator, and a biking posture state indicator.

11. The method of claim 1, further comprising displaying a playback field configured to allow a user to review historical posture state data on a temporal basis.

12. The method of claim 1, further comprising delivering electrical stimulation therapy to the patient according to the posture state data.

14. The method of claim 1, wherein the first posture state is different from the second posture state.

15. The method of claim 1, wherein presenting an indicator indicative of the determined first posture state and second posture state comprising presenting a first indicator indicative of the first posture state at substantially a same time as presenting a second indicator of the second posture state.

16. The system of claim 1, wherein the user interface presents a first indicator indicative of the first posture state at substantially a same time as presenting a second indicator of the second posture state.

13. A system comprising:

a user interface; and

at least one processor configured to receive posture state data from a medical device, determine a first posture state of the patient at a time based on the posture state data using a first detection criteria;

determine a second posture state of the patient at the time based on the posture state data using a second detection criteria different from the first detection criteria,

control the user interface to present an indicator indicative of the determined first posture state and second posture state.

17. The system of claim 13, wherein the first posture state and second posture state include at least one of real-time patient posture state, asserted patient posture state, and stable patient posture state.

18. The system of claim 13, wherein the medical device is configured to deliver therapy to the patient.

19. The system of claim 13, wherein the user interface presents the indicator by at least presenting one or more graphical representations representative of the first posture state and the second posture state.

20. The system of claim 13, wherein the processor receives the posture state data from the medical device in real-time or near real-time with generation of the posture state data.

21. The system of claim 13, wherein the user interface is configured to present at least one of a posture state text, an activity level, and a raw signal data graph based upon the posture state data.

22. The system of claim 13, wherein the user interface presents a stable posture state indication indicative of a stable posture state used by the medical device to deliver therapy and presents an unstable posture state indication indicative of an unstable posture state not used by the medical device to delivery therapy.

23. The system of claim 22, wherein the unstable posture state presented by the user interface comprises at least one of a real-time posture state or asserted posture state.

24. The system of claim 13, wherein the processor receives the posture state data from the medical device at a stream rate between about 1 Hz and about 3 Hz.

25. The system of claim 13, wherein the user interface presents at least one of an upright posture state indicator, a reclining posture state indicator, a lying back posture state indicator, a lying front posture state indicator, a lying left posture state indicator, a lying right posture state indicator, a running posture state indicator, and a biking posture state indicator.

26. The system of claim 13, wherein the user interface is configured to display a playback field configured to allow a user to review historical posture state data on a temporal basis.

27. The system of claim 13, wherein the medical device is configured to deliver electrical stimulation therapy to the patient according to the posture state data.

28. The system of claim 13, wherein the first posture state is different from the second posture state.

29. A system comprising:

means for receiving posture state data for a patient from a medical device;

means for determining a first posture state of the patient at a time based on the posture state data using a first detection criteria;

means for determining a second posture state of the patient at the time based on the posture state data using a second detection criteria different from the first detection criteria; and

means for presenting an indicator indicative of the determined first posture state and second posture state.

30. A non-transitory computer-readable storage medium comprising instructions that cause one or more processors to:

receive posture state data for a patient from a medical device; and

determine a first posture state of the patient at a time based on the posture state data using a first detection criteria;

determine a second posture state of the patient at the time based on the posture state data using a second detection criteria different from the first detection criteria;

control a user interface to present an indicator indicative of the determined first posture state and second posture state.
