After a baseline polysomnography (PSG), subject will receive 100 mg of placebo 30 minutes prior to their 2nd PSG and will receive 100mg trazodone 30 minutes prior to their 3rd PSG.

Sleep Bruxism

TMJ Pain

Chronic Pain

Sleep Disorder

BASELINE PSG Patient has to sleep over at the hospital (sleep lab). The technician will place several sensors on your scalp, temples, chest and legs to record all the data needed for your evaluation. You will be monitored throughout the duration of the test (approximately 6 hours). Brain waves, eye movements, chin muscle tone, breathing patterns, snoring, heart rate, blood pressure, blood oxygen level, body position and muscle activity will be recorded.

polysomnography

100 mg trazodone or placebo given once 30 minutes prior to 2nd PSG

Trazodone

placebo per os 30 minutes prior to 2nd PSG

Placebos

2nd psg, done 1 week after baseline. Patient has to sleep over at the hospital (sleep lab). The technician will place several sensors on your scalp, temples, chest and legs to record all the data needed for your evaluation. You will be monitored throughout the duration of the test (approximately 6 hours). Brain waves, eye movements, chin muscle tone, breathing patterns, snoring, heart rate, blood pressure, blood oxygen level, body position and muscle activity will be recorded.

100 mg trazodone per os 30 minutes prior to 3rd PSG

100 mg placebo per os 30 minutes prior to 3rd PSG

placebos

3rd PSG, done 2 weeks after baseline. Patient has to sleep over at the hospital (sleep lab). The technician will place several sensors on your scalp, temples, chest and legs to record all the data needed for your evaluation. You will be monitored throughout the duration of the test (approximately 6 hours). Brain waves, eye movements, chin muscle tone, breathing patterns, snoring, heart rate, blood pressure, blood oxygen level, body position and muscle activity will be recorded.

Accuracy and Efficacy of Trazodone (Desyrel) on Sleep Quality and Pain Management of TMD Patient

Stabilisation de la qualité du Sommeil Chez le Sujet en Douleurs Orofaciales Chroniques - étude expérimentale en chassé croisé : Trazodone/ Placebo

Based on visual analysis of these parameters:
Sleep stage shifts: change from deeper to lighter sleep stage (stage 2, 3&4, REM toward stages 1 or 2); measured as number/hour.
Awakening: presence of alpha and beta electroencephalography (EEG) activities, with rise in submental/chin muscle tone, lasting>10s; measured as number/hour.
Movement arousal: an EEG pattern or awakening associated with major body movement; measured as number/hour.
Microarousal (MA): abrupt shift in EEG frequency lasting more than 3s and less than 10, excluding spindles and K-complexes; measured as number/hour.
Heart rate rapid fluctuations: acceleration of heart beat within 15s recorded by 2 electrodes at thoracic positions. Measured as number/hour.
Presence and severity of abnormal values will be determined based on AASM recommended cutoffs. For value reference in TMD women participants, see Dubrovksy et al 2014. We hypothesize all these parameters would decrease in Trazodone group.

Based on visual analysis of these parameters:
Sleep duration: from time in bed to wake as estimated by EEG (minutes) Sleep efficiency: % time asleep/time in bed (time in minutes) Sleep fragmentation: index of all above criteria (point 1) number/hour Sleep latency: from light off to first sign of sleep on EEG (minutes). REM sleep latency: from sleep onset (on EEG) to first REM sleep stage (minutes).
Presence and severity of abnormal values will be determined based on AASM recommended cutoffs. For references of values in TMD women participants, see Dubrovksy et al 2014. We hypothesize that sleep duration and efficiency will improve in Trazodone group, while sleep fragmentation, sleep latency, and REM sleep latency will decrease.

Measured with a numerical rating scale (0 to 10) were 0 is poorest possible sleep quality and 10 is the greatest possible sleep quality

Measured with a numerical rating scale (0 to 100) were 0 is no pain and 100 is the most intense pain imaginable.
