movement disorder\n\nOverview\n\nSymptoms\n\nDiagnosis\n\nCauses\n\nProviders (8)\n\nPediatric periodic limb movement disorder (pe·ri·od·ic - limb - move·ment - dis·or·der) or PLMD describes the uncontrolled and repetitive movements that occur during sleep.\n\nOverview\n\n## What is a pediatric periodic limb movement disorder?\nPLMD is a neurological disorder (impacting the brain, spine and connecting nerves) that affects a child’s ability to lie still during the night and may impact the duration and quality of sleep. Formerly known as sleep myoclonus or nocturnal myoclonus, PLMD can affect any age or gender.\n\nThe brief movements typically occur in the legs every 20 to 40 seconds. They happen in clusters, which can last from a few minutes to a few hours. The PLMD motions can come and go and may not happen every night. The clusters’ time lengths may also vary.\n\nMost children and adolescents are unaware that they are occurring, but stronger motions often wake a child up from sleep. The PLMD movements can be brief muscle twitches, jerking, leg kicks (jerky legs) or cause the foot to flex.\n\nChildren with PLMD also often have [restless leg syndrome (RLS)](https:\/\/www.childrens.com\/specialties-services\/conditions\/restless-legs-syndrome), which is an uncontrollable need to move their legs while awake, typically in response to pain or discomfort.\n\nPLMD and RLS are both unconscious and uncontrollable needs to move the lower limbs. The difference is when they occur – children with PLMD symptoms will be asleep and not aware that they are occurring. RLS symptoms occur when children are awake.\n\nRead More\n\n## What is a pediatric periodic limb movement disorder?\nPLMD is a neurological disorder (impacting the brain, spine and connecting nerves) that affects a child’s ability to lie still during the night and may impact the duration and quality of sleep.

Boilerpipe Text	PLMD is a neurological disorder (impacting the brain, spine and connecting nerves) that affects a child’s ability to lie still during the night and may impact the duration and quality of sleep. Formerly known as sleep myoclonus or nocturnal myoclonus, PLMD can affect any age or gender. The brief movements typically occur in the legs every 20 to 40 seconds. They happen in clusters, which can last from a few minutes to a few hours. The PLMD motions can come and go and may not happen every night. The clusters’ time lengths may also vary. Most children and adolescents are unaware that they are occurring, but stronger motions often wake a child up from sleep.

limb - move·ment - dis·or·der) or PLMD describes the uncontrolled and repetitive movements that occur during sleep. Overview ## What is a pediatric periodic limb movement disorder? PLMD is a neurological disorder (impacting the brain, spine and connecting nerves) that affects a child’s ability to lie still during the night and may impact the duration and quality of sleep. Formerly known as sleep myoclonus or nocturnal myoclonus, PLMD can affect any age or gender. The brief movements typically occur in the legs every 20 to 40 seconds. They happen in clusters, which can last from a few minutes to a few hours. The PLMD motions can come and go and may not happen every night. The clusters’ time lengths may also vary. Most children and adolescents are unaware that they are occurring, but stronger motions often wake a child up from sleep. The PLMD movements can be brief muscle twitches, jerking, leg kicks (jerky legs) or cause the foot to flex. Children with PLMD also often have [restless leg syndrome (RLS)](https://www.childrens.com/specialties-services/conditions/restless-legs-syndrome), which is an uncontrollable need to move their legs while awake, typically in response to pain or discomfort. PLMD and RLS are both unconscious and uncontrollable needs to move the lower limbs.

Signs and Symptoms ## What are the signs and symptoms of a pediatric periodic limb movement disorder? Children may and babies may wake up due to body movements in the middle of the night or have chronic [insomnia](https://www.childrens.com/specialties-services/conditions/difficulty-in-falling-asleep-or-staying-asleep). They may also have difficulty staying asleep, which can cause [extreme daytime tiredness](https://www.childrens.com/specialties-services/conditions/excessive-daytime-sleepiness) and may also lead to other [sleep disorders.](https://www.childrens.com/specialties-services/specialty-centers-and-programs/sleep) Additional PLMD symptoms may vary and come and go, including the following: - Behavioral health issues, including [anxiety](https://www.childrens.com/specialties-services/conditions/anxiety), anger, [depression](https://www.childrens.com/specialties-services/conditions/depression), hyperactivity, irritability, impulsiveness and poor concentration - Erratic leg movements during unconscious sleep (kicking, jerky legs, twitching or flexing the foot) - Falling asleep during the day - Resisting bedtime - Restless sleep - Tossing and turning in bed Read More ## What are the signs and symptoms of a pediatric periodic limb movement disorder?

The exact cause of PLMD is unknown. Experts have suggested the underlying sources may be related to low iron levels (with or without [anemia](https://www.childrens.com/specialties-services/conditions/anemia)) or problems with nerve conduction (the speed and strength of the nerve signal between cells) due to a chronic disease.

Readable Markdown	PLMD is a neurological disorder (impacting the brain, spine and connecting nerves) that affects a child’s ability to lie still during the night and may impact the duration and quality of sleep. Formerly known as sleep myoclonus or nocturnal myoclonus, PLMD can affect any age or gender. The brief movements typically occur in the legs every 20 to 40 seconds. They happen in clusters, which can last from a few minutes to a few hours. The PLMD motions can come and go and may not happen every night. The clusters’ time lengths may also vary. Most children and adolescents are unaware that they are occurring, but stronger motions often wake a child up from sleep. The PLMD movements can be brief muscle twitches, jerking, leg kicks (jerky legs) or cause the foot to flex. Children with PLMD also often have [restless leg syndrome (RLS)](https://www.childrens.com/specialties-services/conditions/restless-legs-syndrome), which is an uncontrollable need to move their legs while awake, typically in response to pain or discomfort. PLMD and RLS are both unconscious and uncontrollable needs to move the lower limbs. The difference is when they occur – children with PLMD symptoms will be asleep and not aware that they are occurring. RLS symptoms occur when children are awake.
