Is Periodic Limb Movement Disorder similar to Restless Legs Disorder?
No it isn’t. See for youself:
Periodic Limb Movement Disorder (PLMD), is also known as Nocturnal myoclonus. It is categorized as a sleep disorder and it is displayed when a person moves his or her limbs unwillingly during sleep. They also have some problems related to the movement. Fortunately, if the person moves limbs during sleep but without experiencing any negative sensations, this condition is just Periodic Limb Movements of Sleep (PLMS).
Not all patients with Periodic Limb Movements of Sleep possess Periodic Limb Movement Disorder.
Actually, most people with Periodic Limb Movements of Sleep do not have a sleep disorder.
For that reason, they don’t require any treatment.
Study shows that PLMS varies from a small muscle movement in toes and ankles, and capable of reaching rough swing around of all four limbs, quite violently and/or uncontrollably.
These movements are happening more often in the person’s legs than arms.
The occurrence of Periodic Limb Movements of Sleep and/or Periodic Limb Movement Disorder is in the range from a fraction of a second to several seconds, with repetitive intervals between 5 sec and 1.5 minutes.
