Abstract

The disclosure relates to a method and system for obtaining baseline patient information. In some examples, a method may include acquiring first patient data, wherein the first patient data comprises at least one of first posture state data indicative of a plurality of posture states of a patient during a first time period or first therapy adjustment data indicative of a plurality of patient therapy adjustments made during the first time period; generating baseline patient information based at least in part on the first patient data; and comparing the baseline patient information to patient information generated based on second patient data. Therapy is not delivered to the patient according to a detected posture state of the patient during the first time period, and therapy is delivered to the patient according to the detected posture state of the patient during the second time period.

4. The method of claim 2, wherein the baseline therapy adjustment information comprises a number of therapy adjustments received over the first time period.

5. The method of claim 1, further comprising modifying one or more aspects of the therapy based on the comparison of the baseline patient information and the patient information.

6. The method of claim 5, wherein modifying one or more aspects of the therapy based on the comparison comprises at least one of terminating, adjusting, or initiating one or more aspects of posture-responsive therapy.

7. The method of claim 1, further comprising generating the first posture state data, wherein generating the first posture state data comprises receiving posture state sensor data and detecting the posture state of the patient based on the posture state sensor data.

8. The method of claim 1, wherein comparing the baseline patient information to patient information generated based on the second patient data comprises presenting at least a portion of the baseline patient information and at least a portion of the patient information to a user via a user interface display of an external device.

9. The method of claim 1, wherein comparing the baseline patient information to patient information generated based on the second patient data comprises determining one or more differences between the baseline patient information and the patient information generated based on the second patient data.

10. The method of claim 9, further comprising presenting the one or more differences between the baseline patient information and the patient information generated based on the second patient data to a user via a user interface display of an external device.

11. The method of claim 1, further comprising:

acquiring the second patient data; and

generating the patient information based at least in part on the second patient data.

12. The method of claim 1, wherein at least a portion of the first time period is after the second time period.

13. The method of claim 1, wherein the first time period comprises a time period after the second time period and a time period before the second time period, wherein the baseline patient information comprises first baseline patient information based on patient data from the time period after the second time period and second baseline patient information based on patient data from the time period before the second time period.

14. A system comprising:

a processor configured to acquire first patient data, generate baseline patient information based at least in part on the first patient data, and compare the baseline patient information to patient information generated based on second patient data,

wherein the first patient data comprises at least one of first posture state data indicative of a plurality of posture states of a patient during a first time period or first therapy adjustment data indicative of a plurality of patient therapy adjustments during the first time period,

wherein the second patient data comprises at least one of second posture state data indicative of a plurality of posture states of the patient during a second time period or second therapy adjustment data indicative of a plurality of patient therapy adjustments during the second time period,

wherein therapy is not delivered to the patient according to a detected posture state of the patient during the first time period, and therapy is delivered to the patient according to the detected posture state of the patient during the second time period.

15. The system of claim 14, wherein the baseline patient information comprises at least one of baseline posture state information or baseline therapy adjustment information.

16. The system of claim 15, wherein the baseline postures state information comprises at least one of sleep quality baseline information, proportional posture baseline information, or posture state adjustment information.

17. The system of claim 15, wherein the baseline therapy adjustment information comprises a number of therapy adjustments received over the first time period.

18. The system of claim 14, wherein the processor is configured to modify one or more aspects of the therapy based on the comparison of the baseline patient information and the patient information.

19. The system of claim 18, wherein the processor is configured to modify the one or more aspects of the therapy by at least one of terminating, adjusting, or initiating one or more aspects of posture-responsive therapy.
