Periodic limb movement disorder (PLMD) involves repetitive movements of the arms, legs, or feet during sleep. RLS only occurs while a person is awake or on the verge of sleep, but more than 80% of people with RLS also have a sleep-related movement disorder that happens during sleep-called periodic limb movement disorder. Although thereвЂ™s no single medication for more severe RLS, nutritional supplementation, medical treatments, and lifestyle changes are usually effective at reducing symptoms. The symptoms of RLS are usually relieved by moving the affected limbs. This condition is sometimes associated with genetics, pregnancy, nutrient deficiencies, and medical conditions, but often the exact causes of RLS are unknown.

People with RLS describe sensations that occur in the legs, arms, and even the neck as uncomfortable, irritating, or painful. RLS affects between 7% and 10% of the population. Virtually all patients with RLS report disturbed sleep. The strong desire to move or relieve these urges makes it difficult to fall asleep or go back to sleep after waking up during the night. Urges most often occur during the evening when a person is inactive. Restless leg syndrome (RLS) is a condition in which a person experiences strong, sometimes irresistible urges to move their limbs. They differ from more complex movements seen in parasomnias, like sleepwalking and night terrors. These movements are usually simple, like a quick jerk or twitch. Sleep-Related Movement DisordersДЄccording to the International Classification of Sleep Disorders (ICSD-3), sleep-related movement disorders are a category of sleep disorder in which repetitive movements interfere with sleep. Understanding these conditions is a helpful first step to finding relief. Fragmented or interrupted sleep can lead to daytime consequences, such as fatigue and trouble concentrating at school or work. They can also make sleep more challenging for anyone sharing a bed with someone coping with one of these disorders. But for millions of people diagnosed with a sleep-related movement disorder, nighttime movements increase before or during sleep.ДЄbnormal movements can make it difficult to get sufficient, quality rest. For most of us, this movement slows once we find a comfortable position and fall asleep.

People commonly shift and move around after getting into bed.
