Periodic Limb Movement Disorder. Periodic limb movement disorder involves a rhythmic jerking of the legs and sometimes arms, which may result in poor quality sleep and daytime fatigue. Unlike restless leg syndrome, these movements are involuntary and usually take place when a person is asleep.
Functional movement disorders (FMDs) are clinical syndromes defined by the occurrence of abnormal involuntary movements that are incongruent with a known neurologic cause and are significantly improved on neurological exam with distraction or nonphysiologic maneuvers [ 1 ].n most reports of adults and children with FMD, functional tremor is the most frequent type of involuntary movement, followed by functional dystonia [ 20,27-29 ].
