Abstract

The temporal correlation between a bioelectrical brain signal of a patient and patient motion data, such as a signal indicative of patient motion or a patient posture indicator, is displayed by a display device. In some examples, the patient posture indicator comprises a graphical representation of at least a portion of a body of the patient. In some examples, the temporal correlation between a bioelectrical brain signal, a signal indicative of patient motion, and a signal indicative of cardiac activity of the patient is displayed by the display device.

Claims

1. A method comprising:

displaying, with a display device, a bioelectrical brain signal of a patient; and

generating and displaying, with the display device, a patient posture indicator that is temporally correlated with a segment of the bioelectrical brain signal, wherein the patient posture indicator comprises a graphical representation of at least a portion of a body of the patient.

2. The method of claim 1, further comprising displaying a representation of a temporal correlation between a bioelectrical brain signal of a patient and a signal indicative of motion of the patient.

3. The method of claim 2, further comprising displaying a sliding window that highlights the segment of the bioelectrical brain signal and a portion of the signal indicative of motion of the patient that were sensed during a common time period.

4. The method of claim 1, wherein generating the patient posture indicator comprises:

determining a posture state of a patient indicated by a portion of a signal indicative of patient motion temporally correlated with the segment of the bioelectrical brain signal; and

determining the patient posture indicator based on the determined posture state.

5. The method of claim 4, wherein the patient posture state comprises a posture state associated with at least one of a fall, a sitting upright after a fall, standing upright after a fall, a tonic seizure component, a clonic seizure component, a tonic-clonic seizure, convulsive activity, nocturnal seizure activity, a dystonic-type movement, a compulsive motor activity, or a tic behavior.

6. The method of claim 1, wherein displaying the patient posture indicator comprises displaying, with the display device, a plurality of patient posture indicators that are temporally correlated with respective segments of the bioelectrical brain signal of the patient.

7. The method of claim 1, wherein displaying the plurality of patient posture indicators comprises displaying one patient posture indicator of the plurality of patient posture indicators at a time.

8. The method of claim 1, further comprises generating a marker that identifies a portion of the bioelectrical brain signal temporally correlated with a change in a posture state of the patient.

9. The method of claim 1, further comprising displaying a signal indicative of cardiac activity of the patient that is temporally correlated to the bioelectrical brain signal of the patient and the patient posture indicator.

10. The method of claim 1, further comprising receiving user input selecting a type of patient posture indicator, wherein displaying, with the display device, the bioelectrical brain signal of a patient comprises displaying the bioelectrical brain signal that temporally correlates to the type of patient posture indicator.

11. A system comprising:

a user interface; and

a processor that displays via the user interface a bioelectrical brain signal of a patient and a patient posture indicator that is temporally correlated with a segment of the bioelectrical brain signal, wherein the patient posture indicator comprises a graphical representation of at least a portion of a body of the patient.

12. The system of claim 11, wherein the processor displays via the user interface a signal indicative of motion of the patient.

13. The system of claim 11, wherein the processor generates the patient posture indicator based on a signal indicative of motion of the patient by at least determining a posture state of the patient indicated by a portion of the signal temporally correlated with the segment of the bioelectrical brain signal and determining the patient posture indicator based on the determined posture state.

14. The system of claim 11, wherein the processor displays a sliding window that highlights the segment of the bioelectrical brain signal and the patient posture indicator that indicates the patient posture state when the segment of the bioelectrical brain signal was sensed.

15. The system of claim 11, wherein the processor generates and displays a plurality of patient posture indicators that are temporally correlated with respective segments of the bioelectrical brain signal of the patient.

16. The system of claim 11, wherein the processor displays, via the user interface, an indication of a change in a posture state of the patient on the bioelectrical brain signal.

17. The system of claim 11, further comprising a first sensor that senses the bioelectrical brain signal of the patient and a second sensor that generates a signal indicative of patient motion, wherein the processor generates the patient posture indicator based on the signal indicative of patient motion.

18. The system of claim 11, wherein the processor displays a signal indicative of cardiac activity of the patient that is temporally correlated to the representation of the bioelectrical brain signal of the patient and the patient posture indicator.

19. The system of claim 11, further comprising a user interface, wherein the processor receives user input via the user interface selecting a type of patient posture indicator, and displays the bioelectrical brain signal that temporally correlates to the type of patient posture indicator.

20. A system comprising:

means for displaying a bioelectrical brain signal of a patient; and

means for generating a patient posture indicator that is temporally correlated with a segment of the bioelectrical brain signal, wherein the patient posture indicator comprises a graphical representation of at least a portion of a body of the patient, wherein the means for displaying displays the patient posture indicator such that the patient posture indicator is temporally associated with the segment of the bioelectrical brain signal.

21. The system of claim 20, further comprising means for displaying a sliding window that highlights the segment of the bioelectrical brain signal and the patient posture indicator that indicates the patient posture state when the segment of the bioelectrical brain signal was sensed.

22. The system of claim 20, further comprising means for generating a signal indicative of cardiac activity and means for displaying the signal and indicating a temporal correlation with the representation of the bioelectrical brain signal of the patient.

23. A computer-readable medium comprising instructions that cause a programmable processor to:

display a bioelectrical brain signal of a patient; and

generate and display a patient posture indicator that is temporally correlated with a segment of the bioelectrical brain signal, wherein the patient posture indicator comprises a graphical representation of at least a portion of a body of the patient.

24. The computer-readable medium of claim 23, further comprising instructions that cause the processor to display a sliding window that highlights the segment of the bioelectrical brain signal and the patient posture indicator.

25. The computer-readable medium of claim 23, further comprising displaying a signal indicative of cardiac activity of the patient that is temporally correlated to the representation of the bioelectrical brain signal of the patient.
