Method and apparatus for closed-loop deep brain stimulation in treating neurological diseases
First Claim
1. A device, comprising:
- a stimulation sequence generator device;
at least one implantable electrode for insertion in a brain of a human being, wherein the at least one implantable electrode is coupled to the stimulation sequence generator;
a surface-electromyographic (EMG) sensor for placement on a body part of the human being; and
a controller coupled to the stimulation sequence generator device and the sensor, wherein the controller is operable to;
receive a signal from the surface-EMG sensor;
extract from the signal characteristics corresponding to desirable movements of the body part of the human being to generate output data;
detect a condition from the output data for predicting an upcoming tremor; and
cause the stimulation sequence generator device to apply a stimulation to the at least one implantable electrode for a first period responsive to the detected condition to prevent the upcoming tremor.

Abstract
A system that incorporates teachings of the present disclosure may include, for example, a device having a stimulation sequence generator device, at least one implantable electrode for insertion in a brain of a human being, where the at least one implantable electrode is coupled to the stimulation sequence generator, a sensor for placement on a body part of the human being, and a controller coupled to the stimulation sequence generator device and the sensor. The controller can be operable to receive a signal from the sensor, extract from the signal characteristics corresponding to desirable movements of the body part of the human being to generate output data, detect a condition from the output data for predicting an upcoming tremor, and cause the stimulation sequence generator device to apply a stimulation to the at least one implantable electrode for a first period responsive to the detected condition to prevent the upcoming tremor.
