Patient directed therapy control
First Claim
1. A method comprising:
- detecting at least one biosignal from a brain of a patient that results from a volitional patient input; and
adjusting a therapy parameter of therapy delivered to the patient based on the biosignal.

Abstract
A patient controls the delivery of therapy through volitional inputs that are detected by a biosignal within the brain. The volitional patient input may be directed towards performing a specific physical or mental activity, such as moving a muscle or performing a mathematical calculation. In one embodiment, a biosignal detection module monitors an electroencephalogram (EEG) signal from within the brain of the patient and determines whether the EEG signal includes the biosignal. In one embodiment, the biosignal detection module analyzes one or more frequency components of the EEG signal. In this manner, the patient may adjust therapy delivery by providing a volitional input that is detected by brain signals, wherein the volitional input may not require the interaction with another device, thereby eliminating the need for an external programmer to adjust therapy delivery. Example therapies include electrical stimulation, drug delivery, and delivery of sensory cues.

29. A system comprising:
-
a sensing module configured to sense an electrical signal from within a brain of a patient; and a processor that evaluates one or more of an alpha, beta, gamma or high gamma frequency band of the electrical signal to determine whether the electrical signal includes a biosignal that is based on a volitional patient input, wherein the processor generates a control signal to control a therapy module if the electrical signal includes the biosignal. - View Dependent Claims (30)
