Therapy control based on a patient movement state
First Claim
1. A method comprising:
- sensing a brain signal within a dorsal-lateral prefrontal cortex of a brain of a patient;
determining the brain signal indicates prospective movement of the patient; and
controlling operation of a device, based on determining the brain signal indicates prospective movement of the patient, to deliver at least one neurostimulation therapy or fluid therapy to the patient.

Abstract
A movement state of a patient is detected based on brain signals, such as an electroencephalogram (EEG) signal. In some examples, a brain signal within a dorsal-lateral prefrontal cortex of a brain of the patient indicative of prospective movement of the patient may be sensed in order to detect the movement state. The movement state may include the brain state that indicates the patient is intending on initiating movement, initiating movement, attempting to initiate movement or is actually moving. In some examples, upon detecting the movement state, a movement disorder therapy is delivered to the patient. In some examples, the therapy delivery is deactivated upon detecting the patient is no longer in a movement state or that the patient has successfully initiated movement. In addition, in some examples, the movement state detected based on the brain signals may be confirmed based on a signal from a motion sensor.

18. A system comprising:
-
a sensing module configured to sense a brain signal within a dorsal-lateral prefrontal cortex of a brain of the patient; and a controller configured to determine the brain signal indicates prospective movement of the patient and control a device, based on the determination the brain signal indicates prospective movement of the patient, to deliver at least one of neurostimulation therapy or fluid therapy to the patient. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

35. A non-transitory computer-readable medium comprising instructions that, when executed by the processor, cause the processor to:
-
receive a brain signal sensed within a dorsal-lateral prefrontal cortex of a brain of the patient; determine the brain signal indicates prospective movement of the patient; and control operation of a device, based on determining the brain signal indicates prospective movement of the patient, to deliver at least one of neurostimulation therapy or fluid therapy to the patient.
