Abstract
A closed loop feedback drug delivery system for controlling muscle activity, e.g., spasticity. The system includes a sensor, e.g., an EMG sensor, for monitoring muscle activity and generating a detected muscle activity signal. A controller automatically adjusts at least one of timing and dosage of a drug administered to control muscle activity based on the detected muscle activity signal and produces a control signal. Administering of the drug, e.g., an antispasmodic drug, for controlling muscle activity based on the control signal is performed by an infusion pump. The drug after being emitted from the pump is then delivered to the spinal cord of the patient using an intrathecal catheter.
