Texto completo da fonteIntroduction : Knowledge about the role of kinesophobia in the chronicization of pain is limited. This work therefore sought to associate neurophysiological aspects to try to understand how it is involved in this chronicization. In addition, an alternative measurement tool for kinesiophobia was translated and validated in French. Methods : Five studies were conducted. The first three sought to evaluate the relationships between kinesiophobia and adaptations induced by shoulder pain on the descending pain modulation system in 20 subjects (via conditioned pain modulation), corticospinal excitability (via recruitment curves in transcranial magnetic simulation), as well as on the kinematics, muscle activity and muscle synergies of the shoulder (in 30 subjects) during a pointing task. The fourth study evaluated the feasibility of inducing kinesiophobia with a false ultrasound diagnosis in 20 subjects (including 10 controls) while measuring the effect on corticospinal excitability. The fifth translated and validated the scale of the components of fear and avoidance in a study of 55 chronic pain patients. Results : for the first three studies, pain reduced shoulder muscle activity and, coupled with high kinesiophobia, led to a reduction in the distance traveled by the finger to the target. Correlations were found between the kinesiophobia score and the variation in the slopes of the recruitment curves ans between the variation in S₅₀ and the dot product of the synergies. Negative correlations were found between conditioned pain modulation and variation in recruitment curve slopes and between variation in S₅₀ and kinesiophobia scores. The fourth study revealed that a false diagnosis had no impact on kinesiophobia or corticospinal excitability due to the absence of a history of pain in the subjects. The fifth study provided better psychometric results than some usual questionnaires. Conclusion : These interactions between the motor system, kinesiophobia ans pain provide clues about the potential elements involved in the chronicization of pain

Texto completo da fonteAbstract : Introduction: Hitherto, our understanding about the neurophysiological mechanisms responsible for the development of chronic pain is still relatively limited. It is suggested that modifications in the efficacy of endogenous pain inhibitory mechanisms could contribute to this phenomenon. Considering the importance of monoaminergic neurotransmission in descending pain modulation, either of inhibitory or facilitatory influence, we hypothesize that temporal persistence of pain can trigger modifications in the functionality of the two major systems (serotoninergic and noradrenergic) underlying these endogenous control mechanisms, thus participating in the development and progression of chronic pain states. General objective: Adopting a translational approach, we explored the association between the functionality (central & peripheral) of monoaminergic neurotransmission and the efficacy of descending inhibitory mechanisms during the development and progression of chronic pain. Clinical results: Our results replicate several observations emanating from the literature demonstrating a diminution in the efficacy of descending pain inhibitory mechanisms (using a conditioned pain modulation paradigm; CPM) in subjects with chronic musculoskeletal pain (CP subjects). In these CP subjects, we also highlight a reduction in basal plasma concentrations of noradrenaline and metanephrine, when compared with pain-free subjects (PF subjects). For all tested subjects (PF and CP subjects), a positive association is observed between CPM efficacy and basal plasma concentrations of noradrenaline and metanephrine. Therefore, basal plasma catecholamines concentrations could be used as molecular indicators of the latent CPM efficacy. Conversely, no difference in monoaminergic activity and no association with CPM efficacy are observed when looking at the molecular content of cerebrospinal fluid. Preclinical results: Here, we expose a new double-hit model of pain in rodents (i.e., initial induction of a persistent pain [the 1st hit] and subsequent activation of descending pain modulatory mechanisms with tonic pain [the 2nd hit]). This experimental paradigm allows us to evaluate the efficacy of decending pain modulation in rodents in the context of chronic pain. Interestingly, we detect a reduction in the behavioral response to tonic pain (in the formalin test), 28 days after the induction of neuropathic pain (chronic constriction injury model; CCI), when compared to sham rats. Even though this reduction in nociceptive behaviors is still present 168 days after neuropathy, the effect seems to wane down over time. Concomitantly, in absence of tonic nociceptive stimulation, an elevation in central concentrations (i.e., cerebrospinal fluid) in serotonin and noradrenaline is observed 12 days after the induction of neuropathic pain, before returning to sham levels on day 28. Moreover, the behavioral response described on day 28 is only observed in a neuropathic pain model (CCI), and absent when inflammatory pain is used as the initial pain. Conclusions: In the context of chronic pain, our results in humans confirm the advent of modifications in the efficacy of descending pain inhibitory mechanisms, while supporting the emerging concept suggesting that individual differences in these mechanisms may be associated with individual differences in peripheral processes (such as the release of catecholamines in plasma), that could ultimately be involved in cardiovascular control. Moreover, our results in rodents suggest that dynamic changes (specific to pain types) in the efficacy of descending pain modulation, as well as in the central functionality of monoaminergic neurotransmission, are present during the progression of chronic pain. Overall, this thesis provides novel information concerning temporal neurophysiological changes in descending pain modulatory mechanisms that may be involved in the development and progression of chronic pain states.

Texto completo da fontePain evaluation in animal experimentation always encountered a limit in the subjectivity of the researcher. In order to allow both better understanding of the nociceptive mechanisms and care of painful patients, it is useful to develop new and objective tools for pain evaluation. Firstly, I validated two new protocols of pain evaluation used on unrestrained animals: dynamic hot/cold plate in order to measure simultaneously hyperalgesia and allodynia, and dynamic weight bearing in order to monitor the postural impairment of the animal. Then, I used radiotelemetry to continuously record body temperature, heart rate and locomotor activity in freely moving animals. Thus, I detected the physiological alterations associated with a spontaneous painful event. Moreover, I developed and validated a new postoperative pain model which have allows demonstrating the preventive analgesia effect of ropivacaine. Finally, I studied the spinal modulation by neurosteroids of nociceptive signal through their relative impact of GABA- and glycinergic inhibition. Furthermore, I showed the implication of spinal endogenous neurosteroidogenesis in the analgesic effect of oxytocin inhibitory control. This work lead to new tools for pain evaluation in unrestrained animals, to the use of the radiotelemetry in the evaluation of pain associated symptoms in freely moving animals, and to a better understanding of the role of spinal endogenous neurosteroids in pain processing

Texto completo da fonteChronic pain often accompanied by anxiety and depression is a global scourge. The modulation of pain by neuropeptides (NP) is well known at the level of primary afferents and the spinal cord. However, little data is available on their role in pain in the brain. The relaxin family includes relaxin, which is present in the central nervous system (CNS) and has antifibrotic properties, and relaxin-3, which is strictly expressed in the CNS and has anxiolytic and antidepressant effects. Our objective is to study the modulation of pain by the neuropeptides relaxin and relaxin-3 in a mouse model of persistent inflammatory pain.Our results show that not only the relaxin-3 / RXFP3 system, but also the relaxin / RXFP1 system, which is still poorly explored in the CNS, have analgesic effects in conditions of inflammatory pain. The sites of action of these peptide systems include cortical (cingulate cortex, claustrum) and subcortical (amygdala) regions that regulate descending pathways and sensory integration in the spinal cord. Our data highlight the therapeutic potential of this peptide family, whose role in pain has never been tested before

Texto completo da fonteThe amygdala is a major control center of the emotions, but also integrates sensory, especially nociceptive information. Cortical afferents to the amygdala largely target its basolateral complex. The basolateral amygdala (BLA) then projects to the central amygdala nucleus, which in turn projects densely to the periaqueductal gray and thus can drive a behavioural output via the spinal cord. Data obtained during my thesis have shown that the balance between excitation and inhibition in the BLA triggers an tonic control of pain. Therefore modulating one of the neurotransmission directly influences the pain threshold of control or nociceptive mice. My thesis work also focused on the functioning of an anxiolytic and non benzodiazepinic drug ; Etifoxin (EFX). This molecule as a positive modulator of GABAA receptors and indirectly by increasing the synthesis of neurosteroids, also known as strong modulator of these receptors. In our team, we already showed that EFX has anti-nociceptive effects when injected intraperitonealy in rats. Here we wanted to determine the action of EFX on pain descending control drive by BLA. We showed that EFX infusion in the BLA seems to be anti-nociceptive, inducing a recover of the pre-cuff mechanical threshold level. We also used a patch-clamp approach to study directly in vitro the modulation of the inhibitory synaptic transmission produced by EFX. We showed that EFX potentiate the inhibition in BLA neurons via different and complementary mechanisms. These potentiating effects are mostly dependent of a neurosteroidogenesis increase
