Candidate leg movement

One 2-second EMG burst • Not a PLMS series

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.

  • The highlighted burst lasts 2 seconds and exceeds an 8 µV rise above resting EMG.
  • A candidate LM is 0.5–10 seconds; assess sleep context and exclusion rules.
