Multiple Choice

PLMS stands for which of the following?

Periodic Limb Movements in Sleep describe repetitive, brief limb movements that occur during sleep, usually in the legs. On a sleep study, these show up as bursts of leg muscle activity separated by quiet periods, typically with inter-movement intervals of about 5 to 90 seconds. When several movements occur in succession (usually four or more), that pattern is identified as PLMS. The term uses “in Sleep” to distinguish these movements from daytime motor phenomena; the other options use terms like “Syndrome” or “Disorder,” which are not how the acronym PLMS is defined.
