Systems, devices, and methods for electrical stimulation using feedback to adjust stimulation parameters
First Claim
1. An electrical stimulation system, comprising:
- an implantable control module configured for implantation in a body of a patient and comprising an antenna and a processor coupled to the antenna, wherein the implantable control module is configured to provide electrical stimulation signals to an electrical stimulation lead coupled to the implantable control module for stimulation of patient tissue;
an external programming unit configured to communicate with the processor of the implantable control module using the antenna and to provide or update stimulation parameters for production of the electrical stimulation signals;
a sensor configured to be disposed on or within the body of the patient and to measure a biosignal indicative of muscle tremor or rigidity; and
a biosignal processor configured to communicate with the sensor to receive the biosignal, to determine a disease/disorder status from the muscle tremor or rigidity indicated by the biosignal, and to generate an adjustment to one or more of the stimulation parameters based on the determined disease/disorder status and the biosignal, wherein the adjustment is configured to steer the electrical stimulation signals to stimulate a region of the patient tissue that is different, at least in part, from a region of the patient tissue stimulated prior to the adjustment.

Abstract
An electrical stimulation system includes a control module that provides electrical stimulation signals to an electrical stimulation lead coupled to the control module for stimulation of patient tissue. The system also includes a sensor to be disposed on or within the body of the patient and to measure a biosignal; and a processor to communicate with the sensor to receive the biosignal and to generate an adjustment to one or more of the stimulation parameters based on the biosignal. The adjustment can be configured and arranged to steer the electrical stimulation signals to stimulate a region of the patient tissue that is different, at least in part, from a region of the patient tissue stimulated prior to the adjustment. Alternatively or additionally, the biosignal is indicative of a particular patient activity and the adjustment is a pre-determined adjustment selected for the particular patient activity.
