We investigated the characteristics of periodic leg movements (PLM) during nocturnal sleep and wakefulness in 13 drug-free patients presenting with the restless legs syndrome (RLS, n = 9) or with isolated PLM (n = 4). Eight-hour polygraphic sleep recordings included the electromyogram (EMG) of both tibialis anterior muscles. Scoring of leg movements was done according to established criteria for periodic movements in sleep, but movements occurring during episodes of wakefulness were scored as… Expand
Time course of arousal response during periodic leg movements in patients with periodic leg movements and restless legs syndrome
TLDR
These over-time variations occurred independently of changes in the rate of PLM associated or not with MA or associated with slow wave activity, suggesting that variations in arousal threshold and sleep propensity did not affect the PLM arousing effect. Expand
Periodic leg movements in REM sleep behavior disorder and related autonomic and EEG activation
TLDR
In idiopathic RBD, the reduction of cardiac and EEG activation associated with PLMS suggests the presence of an impaired autonomic and cortical reactivity to internal stimuli. Expand
Are periodic leg movements during sleep (PLMS) responsible for sleep disruption in insomnia patients?
TLDR
The lack of significant differences in both the macro‐ and micro‐structure of sleep and EEG activity content regarding the association with movements confirm the hypothesis that periodic leg movements did not primarily cause sleep disturbance. Expand
The influence of sex, age and sleep/wake state on characteristics of periodic leg movements in restless legs syndrome patients
TLDR
Results indicate that a single state dependent mechanism may be responsible for the periodicity of PLM noted both during sleep and wakefulness. Expand
Motor pattern of periodic limb movements in sleep in idiopathic RLS patients.
TLDR
The results suggest that there are different, independent, and unsynchronized generators forPLMS, suggesting that abnormal spinal cord hyperexcitability may act as the primary cause of PLMS, triggered by unidentified sleep-related factors. Expand
Periodic leg movements in sleep and periodic limb movement disorder: a polysomnographic finding and/or a disorder?
TLDR
periodic leg movements in sleep (PLMS) are a sleep related phenomenon with periodic episodes of repetitive and highly stereotypical movements of the lower extremities that influence some physiological measures such as heart rate, blood pressure and EEG-spectra during sleep. Expand
Periodic leg movements in RLS patients as compared to controls: Are there differences beyond the PLM index?
TLDR
PLM measures revealed a significantly longer mean duration of single PLM during wakefulness and non rapid eye movement (NREM) sleep in RLS patients as compared to controls, and high numbers of PLM sequences of short duration might be an indicator for the decreased sleep quality in R LS patients.

Periodic leg movements and sleep-disordered breathing in children
TLDR
The prevalence of periodic leg movements in sleep in OSAS patients was investigated to answer the question whether OSAS can be misinterpreted by insufficient diagnostics for example actigraphy alone to resolve by the therapy of sleep disturbed breathing. Expand
Motor pattern of periodic limb movements during sleep
TLDR
An abnormal hyperexcitability along the entire spinal cord, especially its lumbosacral and cervical segments, is hypothesize as the primary cause of PLMS, triggered by sleep-related factors located at a supraspinal but still unresolved level. Expand
Periodic leg movements in sleep and periodic limb movement disorder: prevalence, clinical significance and treatment.
TLDR
In sleep studies, PLMS are found most frequently in restless legs syndrome (RLS) and often occur in narcolepsy, sleep apnea syndrome and REM sleep behavior disorder and were found also in various medical and neurological disorders that do not primarily affect sleep. Expand
