Pain, sleep and traumatology

In the population, between 10 and 30% of people, varying with age, report chronic pain and about 2/3 of these patients complain of non restorative sleep. A bad sleep night (fragmented with frequent awekenings, limbs movement and respiratory abnormalities) exacerbates pain and, inversly, a day with pain altears the ability to fall asleep and maintain sleep. A pattern could be installed: a vicious cycle between pain and sleep could affect life quality, daytime alertness and promotes anxiety and mood swings. In the factors that initiate or maintain pain in relation with sleep, there is the patient history of bad sleep hygiene, anxious and depressifs symptoms, catastrophizing events and sleep disorders (insomnia, periodic limbs movement disorder, obstructive sleep apnea). In addition, some predispositions or vulnerabilities could be in cause for sensory alteration leading to hypervigilance and pain.

The laboratory of Pain, Sleep and Traumatology aim to understand the sleep-pain interaction in population with muscoloskeletal pain, head aches as well as acute or chronic post-traumatic pain. On one hand, we aim to target biological factors (enzymatic, genetic), medical factors (cormorbidities) and psychophysiological factors (cyclic activities of the central nervous system and autonomic nervous system) which could contribute to initiate or maintain the pain-sleep vicious cycle in some individuals and not others. On the other hand, we have multiple projects aiming to understand the effect of sleep on the placebo analgesia (conditionning effect and relief expectations), the relationship between the use of painkillers and sleep loss (opiate analgesics and others) as well as the low efficiency of painkillers when sleep is affected. Finally, the study of bruxism (teeth grinding) during sleep allowed our laboratory to better understand the relationship between excessive muscular activity, pain, respiration and ponctual increases in autonomic nervous system activity. This research projects are financed with a Canada Research Chair in pain, sleep and traumatic injuries, the CIHR, FRQ-S and the Réseau Québécois de recherche sur la douleur.
