1. A method of detecting sleep-related disorder events, comprising:

  • sensing a plurality of physiological signals including at least muscle movement signals comprising electromyogram signals;

    detecting the sleep-related disorder events using the sensed physiological signals, the sleep-related disorder events comprising involuntary muscle movement events of non-respiratory muscles and sleep-disordered breathing events, the detection of the sleep-disordered breathing events and the involuntary muscle movement events based at least in part on the electromyogram signals; and

    calculating a composite sleep disorder index, the composite sleep disorder index quantifying combined effect of the involuntary muscle movement events and the sleep-disordered breathing events, wherein at least one of calculating and detecting is implemented at least in part patient-internally using a circuit.
