Psychosocial aspects of chronic pain in a clinical pediatric sampleMiller, Megan M. 04 1900 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Chronic pain, defined as pain lasting more than 3 months, is a common and costly health condition. Thirty-three percent of adults and upwards of 35% of children report experiencing pain due to various diseases, disorders, or accidents. Recent research has identified perceived injustice and anger as important constructs in an adult’s pain experience and a possible focus for intervention efforts. The present study explored the extent to which perceived injustice and anger expression operate similarly in children with chronic pain as in adults. This was a retrospective analysis of data from 122 patients seeking treatment at a pediatric pain clinic. Results supported anger expression as a mediator in the relationship between perceived injustice and pain intensity but not psychological distress, suggesting that anger expression operates similarly in children as in adults with chronic pain. Unlike previous findings in adults with chronic pain, injustice did not moderate the relationship between pain intensity and psychological distress, suggesting that injustice operates differently in children with chronic pain compared to adults. The strong association between injustice and pain outcomes (i.e. pain intensity, quality of life, functional disability) suggests that injustice is an important construct to explore in the chronic pain experience of children.

Neurophysiological mechanisms of chronic primary spine pain relief by chiropractic spinal manipulation = Mécanismes neurophysiologiques du soulagement de la douleur vertébrale chronique primaire par les manipulations vertébrales chiropratiquesGevers-Montoro, Carlos 04 1900 (has links)
La chiropratique est une profession de la santé qui s’intéresse au diagnostic, au traitement, et à la prévention des troubles musculosquelettiques. L’intervention la plus communément utilisée en chiropratique est la manipulation vertébrale (dite « ajustement chiropratique »). D’ailleurs, les consultations en chiropratique sont principalement pour des douleurs vertébrales, particulièrement dans la région lombaire. La lombalgie est la principale cause d'incapacité à travers le monde. Elle engendre des coûts considérables pour la société et les individus atteints. Chez environ un tiers des individus, la lombalgie persiste et devient chronique, entraînant une incapacité et une diminution de la qualité de vie. Chez ces individus, aucun processus pathologique affectant les tissus vertébraux ne peut être mis en évidence. En effet, cette douleur, dite nociplastique, serait plutôt causée par des mécanismes pathologiques du système nociceptif. La lombalgie chronique, dite primaire chez ces individus, est ainsi considérée comme le diagnostic en soi, et non un symptôme secondaire à une pathologie sous-jacente. Chez certains individus, les manipulations vertébrales peuvent soulager la lombalgie chronique primaire. Cependant, leur efficacité comme intervention de première ligne et leurs mécanismes hypoalgésiques restent à démontrer.
L'objectif général de cette thèse est d’examiner les mécanismes hypoalgésiques des manipulations vertébrales. Le premier objectif spécifique est d’examiner les mécanismes hypoalgésiques d’une manipulation vertébrale à l’aide d’un modèle expérimental de douleur persistante chez des individus en santé. Le deuxième objectif spécifique est d’examiner les mécanismes du soulagement de la douleur lombaire chronique primaire par une intervention chiropratique de quatre semaines, qui comprend douze séances de manipulations vertébrales. La thèse comprend deux études empiriques, soit une étude expérimentale et une étude clinique, qui sont précédées d’une revue de littérature ciblée. Le premier article est une revue narrative explorant les mécanismes neurophysiologiques de la manipulation vertébrale pour soulager la douleur vertébrale. Le deuxième article décrit les résultats d’une étude expérimentale chez des individus en santé. Dans cette étude, nous avons examiné les mécanismes d'inhibition de la douleur en réponse à une manipulation vertébrale ciblant un segment vertébral dont la peau a été sensibilisée par une application topique de capsaïcine. Le troisième article est une revue narrative examinant l'efficacité des manipulations vertébrales pour le traitement des douleurs vertébrales. Le quatrième article décrit les résultats d’un essai contrôlé randomisé avec groupe placebo chez des individus atteints de lombalgie chronique primaire. Dans cette étude, nous avons examiné si le soulagement de la lombalgie chronique primaire par une intervention chiropratique s’accompagne d’une atténuation de processus pathologiques contribuant à la douleur nociplastique.
Les résultats indiquent qu’une manipulation vertébrale peut atténuer l’hyperalgésie mécanique secondaire observée avec le modèle expérimental de douleur persistante. Ceci suggère qu’une manipulation vertébrale pourrait agir sur des processus pathologiques qui mènent à la douleur chronique. Ces résultats sont cohérents avec la réduction de la douleur observée chez les patients atteints de lombalgie chronique primaire recevant des manipulations vertébrales. De plus, la réduction de la lombalgie chronique était accompagnée d’une réduction de l’hyperalgésie mécanique lombaire et de la dramatisation de la douleur. Dans l’ensemble, ces résultats suggèrent qu’une intervention chiropratique comprenant des manipulations vertébrales est efficace pour réduire la lombalgie chronique primaire, et que cet effet pourrait découler en partie d’une réduction de processus contribuant à la douleur nociplastique. Ceci renforce les recommandations cliniques sur l’utilisation de la chiropratique pour le soulagement de la lombalgie chronique primaire. D’autres études seront nécessaires pour clarifier les mécanismes neurophysiologiques et anti-inflammatoires des manipulations vertébrales. / Chiropractic is a health profession focused on the diagnosis, treatment, and prevention of musculoskeletal disorders, mainly through spinal manipulation (also known as "chiropractic adjustment"). The majority of patients consult a chiropractor seeking spine pain relief, primarily in the lower back. Low back pain is the leading cause of global disability, generating considerable costs for society and affected individuals. At least one third of people with low back pain experience persistent pain, leading to chronic disability and a decrease in quality of life. In affected individuals, no pathological process affecting the spinal tissues can be identified. Instead, this pain, called nociplastic, is presumed to be caused by pathological mechanisms within the nociceptive system. Thus, in these individuals, low back pain is considered as chronic primary pain, and not the symptom of an underlying disease. In some individuals, spinal manipulations can relieve chronic primary low back pain. However, their effectiveness as a first-line intervention and their hypoalgesic mechanisms remain to be demonstrated.
The overarching aim of this thesis is to examine the hypoalgesic mechanisms of chiropractic spinal manipulations. The first specific objective is to investigate the hypoalgesic mechanisms of a spinal manipulation using an experimental model of persistent back pain in healthy individuals. The second specific objective is to investigate the mechanisms of relief of chronic primary low back pain by a four-week chiropractic intervention, including twelve sessions of spinal manipulations. The thesis includes two empirical studies: an experimental study and a clinical study, both preceded by a targeted literature review. The first study is a narrative review exploring the neurophysiological mechanisms of spinal manipulation to relieve spine pain. The second article describes the results of an experimental trial on healthy individuals, where we examined the mechanisms of pain inhibition following a spinal manipulation targeting a spinal segment sensitized by the topical application of capsaicin The third article is a narrative review examining the effectiveness of spinal manipulation for the treatment of spine pain. The fourth article describes the results of a randomized placebo-controlled trial with individuals suffering from chronic primary low back pain. In this study, we examined whether the relief of chronic primary low back pain by a chiropractic intervention is accompanied by an attenuation of pathological processes contributing to nociplastic pain.
The results indicate that a single spinal manipulation can mitigate segmental mechanical hyperalgesia observed with the experimental model of persistent pain. This suggests that spinal manipulations could act on pathological processes that lead to chronic pain. These results are consistent with the pain reduction observed in patients with chronic primary low back pain receiving spinal manipulations. Furthermore, low back pain relief was accompanied by a reduction in mechanical hyperalgesia and in pain catastrophizing. Overall, these results indicate that a chiropractic intervention including spinal manipulations is efficacious in reducing chronic primary low back pain, and that this effect could in part stem from a reduction in processes contributing to nociplastic pain. This reinforces clinical recommendations on the use of chiropractic for the relief of chronic primary low back pain. Further studies will be needed to clarify the neurophysiological and anti-inflammatory mechanisms of spinal manipulations.

Musculoskeletal pain in primary health care : a biopsychosocial perspective for assessment and treatmentWestman, Anders January 2010 (has links)
Long-term musculoskeletal pain is a large public health problem with serious consequences for both the individual and society. Psychosocial factors have been shown to be good predictors of long-term disability and play an important role in the transition from acute to chronic pain. Early identification and intervention of those that run the risk of developing long-term disability would offer a great opportunity for reducing costs and personal suffering. The overall aim of this thesis was to assess a biopsychosocial approach to the assessment and management of musculoskeletal pain patients in primary health care. To this end, biopsychosocial assessment and treatment methods were tested in two different populations of primary care patients suffering pain. Results indicated that improvements in quality of life and work capacity one year after early multimodal rehabilitation were basically maintained after five years. The most salient prognostic factors determining return to work were educational level and the individual’s perceived health (Study I). Psychosocial factors as measured by the Örebro Musculoskeletal Pain Screening Questionnaire (ÖMPSQ) were related to disability and perceived health three years after treatment for non-acute pain problems (Study II). The experimental group in the controlled multimodal pain rehabilitation programme had lower health care utilization and a reduced risk of using large amounts of medication after three years compared with the participants in the control group. However, there were no significant differences between the groups on variables such as work capacity, function, catastrophizing and pain (Study III). Distinct profiles of catastrophizing, fear-avoidance beliefs, and distress were extracted and meaningfully related to future sick leave and dysfunction (Study IV). Our findings provide support for the biopsychosocial model and highlight the importance of psychosocial factors in long-term outcome. The results underscore the need for early identification of patients at risk. Further, multimodal treatment that covers not only biological but also psychosocial factors seems to be a key to successful treatment, and ideally this intervention should be matched to the patients' needs.
