To date, there is no consensus about the definition and diagnostic grading of bruxism. A written discussion was held among an international group bruxism experts as to formulate a suggest system for its operationalisation. The expert defined repetitive jaw-muscle activity characterised by clenching or grinding teeth and/or bracing thrusting mandible. Bruxism has two distinct circadian manifestations: it can occur during sleep (indicated bruxism) wakefulness awake bruxism). For...
Summary In 2013, consensus was obtained on a definition of bruxism as repetitive masticatory muscle activity characterised by clenching or grinding the teeth and/or bracing thrusting mandible and specified either sleep awake bruxism. addition, grading system proposed to determine likelihood that certain assessment actually yields valid outcome. This study discusses need for an updated has following aims: (i) further clarify 2013 develop separate definitions bruxism; (ii) whether is disorder...
One hundred thirty-three cases of restless legs syndrome (RLS), diagnosed with criteria recently formulated by an international study group, were studied questionnaire and all-night polysomnographic recordings. Results show that RLS starts at a mean age 27.2 years before 20 in 38.3% patients. Symptoms often appear one leg only also involve upper limbs about half all cases. Most patients (94%) report sleep-onset insomnia or numerous nocturnal awakenings due to symptoms. A strong relationship...
A survey conducted through personal interviews was done in Canada to estimate the prevalence of subjective symptoms related restless legs syndrome (RLS) and sleep bruxism. Of 2,019 respondents, all over 18 years age, 15% reported leg restlessness at bedtime; 10% unpleasant muscle sensations associated with awakening during irresistible need move or walk. Both these complaints are RLS. The RLS-related increased linearly age. Tooth grinding, a symptom bruxism, by 8% subjects; contrast...
The clinical validity of diagnostic criteria for sleep orofacial motor activity--more specifically, bruxism--has never been tested. Polysomnographic recordings from 18 bruxers and asymptomatic subjects, selected according to American Sleep Disorders Association criteria, were analyzed (1) discriminate bruxism other activities (2) calculate sensitivity, specificity, predictive values research criteria. Clinical observations reports revealed that all reported frequent tooth-grinding during...
<b>Objectives: </b> To assess heart rate (HR) and blood pressure (BP) changes associated with periodic leg movements during sleep (PLMS) or without EEG signs of arousal in subjects primary restless legs syndrome (RLS). <b>Methods: Ten patients RLS (4 women, aged 47.3 ± 13.5 years) underwent one night polysomnography along noninvasive beat-to-beat BP monitoring. PLMS microarousals (PLMS-MA) 10 (PLMS-noMA) were analyzed each subject. Systolic diastolic (SBP, DBP) measured within a 25-beat...
Spontaneous rhythmic masticatory muscle activity (RMMA) during sleep occurs in relation to transient activation the cerebral and autonomic nervous systems of normal subjects patients with bruxism (SB). In this study, we made a quantitative assessment sequential changes cortical electroencephalographic (EEG) autonomic-cardiac activities associated micro-arousals preceding RMMA episodes. We matched 10 SB subjects. The onset episodes was defined terms suprahyoid muscles. patients, an increase...
Rhythmic Masticatory Muscle Activity (RMMA) is frequently observed during sleep in normal subjects and bruxers. We hypothesized that some exhibit RMMA at a lower frequency than Polysomnographic data from 82 were compared with 33 episodes defined as three or more consecutive bursts of masseter EMG activity, without tooth-grinding. Such nearly 60% subjects. A was noted Sleep organization similar between groups. Bruxers had twice many muscle per episode higher amplitude controls RMMA. The high...
Sleep bruxism research diagnostic criteria (SB-RDC) have been applied since 1996. This study was performed to validate these and challenge the hypothesis that pain is associated with lower frequencies of orofacial activities. Polygraphic recordings were made 100 individuals presenting a clinical diagnosis sleep 43 control individuals. TwoStep Cluster analyses (SPSS) variables reveal groupings among bruxers Participants completed questionnaires during screening, diagnosis, recording sessions....
Sleep disturbances are frequently reported in victims following burn injuries. This prospective study was designed to assess sleep quality and examine its daily relationship pain intensity within the first week of hospitalization. Twenty-eight non-ventilated patients were interviewed during 5 consecutive mornings (number observations=140) collect information about perceived (visual analogue scale, number hours, awakenings, presence nightmares). Pain assessed at rest (nighttime, morning, day)...
Oral splints are widely used in the treatment of myofascial pain masticatory muscles, even though their mechanism action is unknown. The present study evaluated therapeutic efficacy using a parallel, randomized, controlled and blind design. Following sample size estimation, 63 subjects were recruited assigned to 3 groups: (1) passive control: full occlusal splint worn only 30 min at each appointment: (2) active palatal 24 h/day: (3) treatment: h/day. On 7 visits over 10 weeks, rated on 100...
<b><i>Objective: </i></b> To assess the frequency of periodic leg movements (PLM) in idiopathic REM sleep behavior disorder (RBD) and to analyze their polysomnographic characteristics associated autonomic cortical activation. <b><i>Background: PLM during (PLMS) wakefulness (PLMW) are typical features restless legs syndrome (RLS), but also frequently observed patients with RBD. <b><i>Methods: Forty RBD underwent one night recording PLMS frequency. features, PLMS-related cardiac activation...
Although the multidimensional nature of pain is now well recognized, there are, nevertheless, very few quantitative tests to measure separate dimensions and little data concerning their relative sensitivity. The present study compares 2 currently available methods, verbal descriptor visual analogue scales. Eight subjects rated painful near-painful heat stimuli by using scales for intensity or unpleasantness choosing most appropriate phrases from lists descriptors. In dimension, relationship...
Abstract Patients with restless leg syndrome (RLS) complain of motor restlessness, usually occurring while they rest in the evening. Two immobilization tests have been described to assess restlessness these patients. In first test, patient sits bed his or her legs outstretched electromyograms are recorded from right and left anterior tibialis muscles for an hour (Suggested Immobilization Test [SIT]); second immobilized a stretcher (Forced [FIT]). current study, SIT FIT were compared patients...
<b><i>Objective:</i></b> To investigate other physiologic changes that occur with periodic leg movements during sleep (PLMS) might be considered to more sensitive indices of fragmentation. <b><i>Background:</i></b> Although PLMS are associated recurrent microarousals (MA), the frequency MA does not correlate objective daytime sleepiness. It is postulated lack correlation results from low sensitivity standard criteria used score MA. <b><i>Methods:</i></b> Ten drug-free patients a polygraphic...
