Movement

Bilateral leg movement

Left and right onsets are 1 second apart

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.

  • Onsets less than 5 seconds apart are treated as one LM, not two.
  • Check the full candidate-LM and series rules before including it in PLMS counts.
