Restless Leg Syndrome: Sleep
built 615 days ago
Additional problems can be caused by periodic limb movement during sleep, which causes the leg muscles to contract for one or two seconds, making the restless leg twitch or jerk. This is repeated as much as three times every minute and can continue for up to an hour before stopping. Sleep is disturbed until the legs settle. The next phase can start an hour or two later and occur for varying lengths of time throughout the night, resulting in hundreds of small movements. This can cause insomnia or sleep disturbance resulting in fatigue and sleepiness during the day.

A disorder of the central nervous system, restless leg syndrome (RLS) is characterized by the irresistible urge to move the legs. This urge usually occurs during sleep or periods of inactivity and is frequently accompanied, or caused by, uncomfortable and unpleasant sensations that are partially or completely relieved by movement. Some of the words patients with RLS use to describe the feeling include “creepy-crawly,” “burning,” “tingling,” “twitching,” and “painful.”

[C]alled Ekbon syndrome, hereditary acromelalgia, anxietas tibialis, or leg jitters, RLS is a fairly common problem. It affects 20 percent of all pregnant women and 15 percent of all Americans over the age of 50. RLS frequently puts in a brief appearance during menopause, so the figures may be higher among menopausal women, but is most likely to bother women after menopause. RLS is both a movement and a sleep disorder, and tends to run in families.
