Quizplus · Accepted Answer

The sleep disturbance described is periodic limb movement syndrome, which is characterized by repetitive muscle movements, usually in the legs, that occur every 20 to 40 seconds during sleep and can severely interrupt sleep. This is not associated with narcolepsy (inappropriate sleep attacks), somnambulism (sleepwalking), or hypnic jerk syndrome (brief muscle jerks that occur as someone is falling asleep).
