    What are Periodic Limb Movement Disorder (PLMD)?

    Periodic limb movement disorder (PLMD), is a condition in which a person’s legs or arms twitch, cramp or move involuntarily and periodically during sleep. Previously, PLMD was referred to as nocturnal myoclonus - rapid, rhythmic contractions of the muscles often seen in seizures. However, PLMD is not myoclonus.

    The movements encountered in PLMD are repetitive and rhythmic and typically occur every 20 to 40 seconds. These movements may sometimes occur five or more times in one hour, or on and off throughout the night during periods of non-REM sleep. Because the movements disrupt sleep and often lead to daytime sleepiness, PLMD is considered a sleep disorder. Usually, partial flexing of the big toe, knee, ankle and sometimes the hip are affected by these rhythmic episodes.

    It is often associated with restless leg syndrome, but they are both different. Restless leg syndrome is a condition characterized by unpleasant sensations in the legs (and sometimes arms) while awake, and an uncontrollable urge to move them for relief. Most people with restless leg syndrome suffer from PLMD. However, those with PLMD do not suffer from restless leg syndrome. As PLMD causes you to be very tired during the day, it can have a detrimental effect on your health and well-being, leading to depression, bad memory, short attention span and fatigue. PLMD is more common amongst middle-aged and older people but can occur at any age.

    Diagnosing Periodic Limb Movement Disorder (PLMD)

    Your doctor will perform a thorough physical examination and medical history to ascertain the diagnosis of PLMD. It is helpful if you can provide a sleep diary detailing your sleep patterns. An Epworth Sleepiness scale will also be able to rate your sleep and show how it affects your daily life.

    An overnight sleep study called a polysomnogram at a sleep center may have to be performed. This test charts your brain waves, heart beat, breathing, and also records your leg and arm movements. It is also useful in detecting any other sleeping disorders.

      • Knee, ankle and big toe joints bend as part of the movements
      • Movements vary from slight to wild kicking and thrashing
      • Movements are rhythmic and repetitive, occurring every 20 to 40 seconds
      • Movements last for about 2 seconds


    What Causes Periodic Limb Movement Disorder (PLMD)?

    The cause of PLMD is unknown, although there are numerous factors that may influence this disorder.

    PLMD is commonly found in people with the following sleeping disorders:

    Underlying conditions that contribute to PLMD

    Underlying medical conditions that contribute to PLMD include:

    • Spinal cord injury
    • Multiple system atrophy – a neurological disorder
    • Sleep-related eating disorder (SRED)
    • Low brain iron
    • Poor circulation
    • Metabolic disorders
    • Kidney disease
    • Rheumatoid arthritis

    Help for Periodic Limb Movement Disorder (PLMD)

    The first step to treating any sleeping disorder is to determine whether there are any underlying causes such as anemia, diabetes or the use of certain antidepressants. Because PLMD is commonly associated with restless leg syndrome, the same medications are used. To date, the most effective medication for PLMD is also used to treat Parkinson’s disease. Sleeping tablets, some anti-seizure medication and narcotic pain killers may also be prescribed.

    Natural Remedies

    Natural and holistic treatments are also extremely effective in promoting calm, rested limbs during sleep and reducing the symptoms of related sleep disorders. Treatments such as herbal and homeopathic remedies consist of entirely natural ingredients to deliver powerful results. Herbs such as Astragalus membranaceous improves functioning of all the body’s organ systems and boosts circulation.

    Aesculus hippocastum (Horse Chestnut) can relieve Periodic Limb Movement and RLS by keeping the blood flowing smoothly even during rest and sleep. Ruscus acluteatus (Butcher’s Broom) relieves pain and discomfort and is useful in the treatment of constipation, water retention, haemorrhoids and varicose veins. In addition, to ensure a quality, restful sleep use herbs such as Hypericum perforatum and Schizandra chinesis. Vitamin supplements such as Calcium lactate, Magnesium lactate and Vitamin B6 can also help to maintain regular sleep patterns.
