Methods and systems for evaluating a pathological condition include
acquiring movement information, such as electromyogram (EMG) information,
and sleep disordered breathing (SDB) information, and detecting the
presence of a pathological condition using both movement and SDB
information. Methods may involve sensing physiological signals including
at least muscle movement signals. Sleep-related disorders are detected
using the sensed physiological signals, the sleep-related disorders
including at least an involuntary muscle movement disorder and
sleep-disordered breathing. Methods and systems also provide for
detecting and treating a sleep-related disorder using movement and SDB
information. Cardiac, respiratory, nerve stimulation, drug, or a
combination of such therapies may be delivered to treat a detected or
diagnosed pathological condition.
