Periodic Limb Movement (PLM)

Periodic limb movement disorder is continuous or wild movements of the feet, arms, or legs during sleep. These movements can last for up to 10 seconds and may repeat after 5 to 90 seconds and can interfere with sleep and cause excessive daytime sleepiness. Periodic limb movement disorder is typically treated with medicines that prevent the movements or help with sleep during the movements. Periodic limb movement disorder is more common in older adults than in younger people.
