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:

determining, based on an output of a posture state sensor of a medical device, a posture state of a patient using first posture state detection criteria;

determining, based on the output of the posture state sensor, the posture state of the patient using the second posture state detection criteria in response to receipt of the user input; and

transmitting, to the medical device, instructions that control delivery of therapy from the medical device to the patient according to the posture state of the patient determined using the second posture state detection criteria,

wherein at least one of the determining the posture state of the patient using first posture state detection criteria, the receiving user input, the determining the posture state of the patient using the second posture state detection criteria, or the transmitting instructions is performed via at least one processor.

2. The method of claim 1, further comprising controlling delivery of therapy to the patient via the medical device according to the posture state of the patient determined using the second posture state detection criteria.

3. The method of claim 2, wherein controlling delivery of therapy to the patient via the medical device according to the posture state of the patient determined using the second posture state detection criteria comprises controlling the delivery of electrical stimulation therapy to the patient according to the posture state of the patient determined using the second posture state detection criteria.

4. The method of claim 1, wherein the determined posture state of the patient includes at least one of a real-time patient posture state, asserted patient posture state, and stable patient posture state.

5. The method of claim 1, further comprising presenting, via the user interface, an indicator indicative of at least one of the posture state of the patient determined using the first posture state detection criteria and the posture state of the patient determined using the second posture state detection criteria.

6. The method of claim 5, wherein presenting, via the user interface, an indicator indicative of at least one of the posture state of the patient determined using the first posture state detection criteria and the posture state of the patient determined using the second posture state detection criteria comprises presenting one or more graphical representations representative of the at least one of the posture state of the patient determined using the first posture state detection criteria and the posture state of the patient determined using the second posture state detection criteria.

7. The method of claim 5, wherein the indicator 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.

8. The method of claim 1, further comprising presenting, via the user interface, an indicator of at least one of the first posture state detection criteria and the second posture state detection criteria.

9. The method of claim 1, further comprising controlling delivery of therapy to the patient via the medical device according to the posture state of the patient determined using the first posture state detection criteria.

10. The method of claim 1, wherein the medical device comprises an implantable medical device, wherein the external device comprises an external programming device configured to program the implantable medical device, and wherein transmitting the instructions comprises transmitting the instruction from the external programming device to the implantable medical device via wireless telemetry.

11. The method of claim 1, wherein the posture state sensor includes a three-axis accelerometer sensor.

12. The method of claim 1, wherein the therapy comprises at least one of electrical stimulation therapy or therapeutic agent delivery therapy.

13. A medical device system comprising:

an external device including a user interface configured to receive user input; and

at least one processor configured to determine, based on an output of a posture state sensor of a medical device, a posture state of a patient using first posture state detection criteria, receive, via the user interface, user input indicating that the posture state of a patient should be determined using second posture state detection criteria, determine, based on the output of the posture state sensor, the posture state of a patient using the second posture state detection criteria in response to receipt of the user input, and transmit, to the medical device, instructions that control delivery of therapy from the medical device to the patient according to the posture state of the patient determined using the second posture state detection criteria.
