The official World Association of Sleep Medicine (WASM) standards for recording and scoring periodic leg movements in sleep (PLMS) and wakefulness (PLMW) developed in collaboration with a task force from the International Restless Legs Syndrome Study Group (IRLSSG).

摘要

The definition and scoring criteria for periodic leg movements (PLM) during sleep have not changed since 1990 and 1993 and are substantially based on the work carried out by Coleman et al. in 1982 . The aim of the Atlas and Scoring Rules was to provide recommendations for the correct recording of motor events, the use of standard terminology and the definition of some common rules to quantify PLM.
