1. A method of evaluating a pathological condition of a patient, comprising:
- sensing muscle movement signals;
implantably storing sensed muscle movement data indicative of the sensed muscle movement signals;
implantably analyzing the stored muscle movement data and detecting a presence of an involuntary muscle movement disorder using the stored muscle movement data;
detecting whether the patient is asleep;
providing a first therapy to treat the involuntary muscle movement disorder in response to a determination that the patient is asleep; and
withholding the first therapy in response to a determination that the patient is not asleep.

Abstract
Methods and systems are directed to evaluating a pathological condition and involve acquiring muscle movement signals, such as electromyogram (EMG) or accelerometer signals, and detecting the presence of the pathological condition. Methods and systems also provide for detecting sleep-related involuntary muscle disorders and non sleep-related involuntary muscle disorders using muscle movement signals. Drug therapy, transcutaneous electric nerve stimulation therapy, or other therapy may be delivered to treat a detected or diagnosed involuntary muscle disorder.

17. A system for evaluating a pathological condition of a patient, comprising:
-
a sensor configured to sense movement of skeletal musculature; a first detector coupled to the sensor; a sleep detector that detects whether the patient is asleep; implantable memory configured to store sensed data associated with an involuntary muscle movement disorder; and an implantable processor coupled to the first detector and the sleep detector, the processor configured to analyze the stored data and to determine a presence of the involuntary muscle movement disorder; and a therapy delivery system coupled to the processor and configured to; provide a first therapy to treat the involuntary muscle movement disorder in response to a determination that the patient is asleep; and withhold the first therapy in response to a determination that the patient is not asleep. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
