Fragmentary myoclonus pattern

Brief, irregular EMG potentials • Enlarged 10-second view

Educational reference, not a diagnostic tool. A scored event, an elevated index and a clinical diagnosis are different things. Follow your facility’s scoring manual, notification policies and clinical protocols.

Very brief potentials occur asynchronously, without a periodic LM sequence.
This excerpt cannot establish excessive fragmentary myoclonus; longer NREM review is needed.

Synthetic teaching example: Fragmentary myoclonus pattern. Brief, irregular EMG potentials • Enlarged 10-second view. Asynchronous brief potentials in Left TA and Right TA over 0–10 seconds. EMG amplitude: µV (synthetic scale); EEG amplitude is illustrative. Original channel labels, time axes and captions preserved.
