La fibromyalgie (FM) touche 1,4 à 2,2 % de la population générale avec une nette prédominance féminine (80 % des sujets). Ce syndrome est caractérisé par des douleurs chroniques diffuses, des troubles du sommeil, des troubles cognitifs, des perturbations émotionnelles et une fatigue chronique. Les mécanismes physiopathologiques de la FM ne sont pas complètement élucidés. Cependant, la FM est considérée comme un syndrome lié au stress. Des déséquilibres du système nerveux autonome (SNA) et de l'axe hypothalamo-hypophyso-surrénalien (HHS) ont été mis en évidence dans la FM. Ce déficit de l’axe du stress (SNA et HHS) induirait secondairement des dysfonctionnements des contrôles endogènes de la douleur. A partir de cette hypothèse et en s’appuyant sur deux essais cliniques, notre objectif est d’évaluer l'efficacité d'un programme d’entraînement spécifique, sur les douleurs et les symptômes des patientes FM. Une première étude observationnelle de cinq ans, démontre qu’une prise en charge globale, associée à un entraînement physique spécifique [3 sessions de 45 minutes par semaine d’entraînement continue à intensité modérée (MICT), progressivement couplé à un entraînement fractionné à haute intensité (HIIT)] améliore considérablement les symptômes de la FM. Les premiers résultats d'une seconde étude, contrôlée et randomisée de 24 mois, confirment des dysfonctionnements des mécanismes de modulation centrale de la douleur, ainsi qu’un déficit de la régulation autonome, chez au moins une fraction des patientes FM. Ce programme d’entraînement spécifique, encadré et individualisé, dont l’intensité des exercices est définie pour rééquilibrer la balance neurovégétative (tonus parasympathique et réactivité sympathique), permettrait via des mécanismes de neuroplasticité centrale, associés aux effets périphériques tels que l'augmentation de la perfusion vasculaire au niveau musculaire, de soigner la fibromyalgie. / Fibromyalgia affects 1.4–2.2% of the general population, predominately women (more than 80% of subjects). This syndrome is characterised by chronic widespread pain, sleep disturbances, cognitive dysfunction, emotional disorders and chronic fatigue.Physiopathological mechanisms of FM are not fully elucidated but FM is considered a stress related syndrome. Studies on the stress axis in FM have demonstrated dysfunction of both the Autonomic Nervous System (ANS) and the Hypothalamic-Pituitary-Adrenal (HPA) axis. This stress axis deficit (ANS and HPA) could consequently induce dysregulation of pain modulation. According to this hypothesis and using two clinical trials, our main objective is to assess the efficacy of a specific training program on pain and symptoms in female fibromyalgia patients.Firstly, a 5-year observational study shows that overall care coupled with specific physical training [3 sessions of 45 minutes per week of Moderate Intensity Continuous Training (MICT) gradually associated with High Intensity Interval Training (HIIT)] may lead to dramatic improvement of FM symptoms. Secondly, the initial results of a 24-month, controlled, randomised trial (RCT) confirm dysregulation of central pain modulation and a deficit of the autonomic balance, at least in a percentage of FM patients. This specific, supervised, individualised training program with exercise intensity defined to rebalance the neurovegetative system (parasympathetic tone and sympathetic reactivity), associated by peripheric effects as the improvement of muscle perfusion, may allow FM to be treated through central neuroplasticity.

<p>This thesis presents hormonal, emotional, physical and visual status changes in female fibromyalgia (FMS) patients after treatment with the Creative Art therapy; dance/movement therapy, compared to controls. FMS is a syndrome of chronic pain involving musculoskeletal aches, stiffness and pain where perturbations in the stress-axis and high scores on somatic anxiety and muscular tension also have been found. The study comprises thirty-six female FMS patients divided in treatment- and control group. Serum concentrations of the hormones prolactin, dehydroepiandrosterone sulphate (DHEA-S), cortisol and neuropeptide Y (NPY) in plasma and cortisol in saliva were analysed. Different verbal self-rating scales concerning well-being, pain, personality and life events among other things have been used. Assessments of the condition of the FMS patients affected by video-viewing were evaluated together with interviews about the self-perception phenomenon of video viewing (a phenomenological hermeneutic method). </p><p>The results of the study show that six months of dance/movement therapy appears sufficient to improve both psychological and physical function, as indicated by the visual analyses. The video interpretation technique (VIT) and self-figure drawings captured treatment effects that were not evident from verbal scales or reflected in hormone levels. The biological markers probably need a longer treatment period to activate the HPA axis and its inter-related hormones and peptides. </p><p>The use of different assessment techniques most likely has affected the treatment outcome. Difficulties perceiving information through verbal/cognitive modalities as well as alexithymia are factors discussed. The VIT may be useful for early identification of maladaptive movement patterns and as a mirror of facial and bodily expressions of emotions. In conclusion, this study indicates that both the dance/movement therapy and the VIT have had great influence on the FMS patient’s well-being, self-perception and perception of pain. </p>

It may be associated with sleep or mood disorders and fatigue, and progresses with functional disability. Its pathogenesis consists of disorders of central pain modulation, involvement of the descending inhibitory system and substance P hyperactivity. The drug most commonly used for treatment of this syndrome is amitriptyline, which leads to an improvement in up to 50% of cases. Patients are interested in trying alternative or complementary medicine for the treatment of fibromyalgia. Panax ginseng C.A. Meyer is an herb that has been used for hundreds of years in oriental medicine. Preclinical studies have confirmed the antinociceptive effect of its active metabolites (ginsenosides) on substance P-induced pain, demonstrating an ability to inhibit calcium channels in dorsal medullary neurons. Clinical trials have shown an improvement in quality of life and fatigue with the use of ginseng. The study had as objective to evaluate the therapeutic efficacy of the extract of P. ginseng roots in controlling pain, fatigue, sleep quality, anxiety and quality of life in fibromyalgia. Fifty-two women of 21-60 years of age, who fulfilled the inclusion criteria of the study, were selected. A randomized, double-blind, controlled clinical trial was carried out over 12 weeks to compare the effect of P. ginseng (100 mg/day) with amitriptyline (25 mg/day) and placebo. Variables evaluated were pain, fatigue, sleep quality and anxiety using a visual analogue scale (VAS); pain was evaluated using a tender points count and quality of life using the Fibromyalgia Impact Questionnaire (FIQ). The patients were evaluated at six follow-up visits and results were expressed as means ± standard error (SE) of the mean using analysis of variation (ANOVA) and Tukey s post-hoc test. Thirty-eight women with a mean age of 43 years concluded the study. There were no statistically significant differences between the three groups with respect to baseline characteristics. VAS revealed a reduction in pain in the ginseng group (p<0.0001) with an improvement ≥ 30% from the sixth week of treatment onwards, an improvement in fatigue (p<0.0001) with a reduction ≥ 25% on the sixth week and ≥ 40% on the ninth week; and an improvement in sleep (p=0.0003) with a reduction ≥ 40% in the frequency of this complaint by the 6th week of treatment. The VAS evaluation of pain, fatigue and sleep detected an improvement compared to baseline values; however, there was no statistically significant difference between the three groups. With respect to anxiety, an improvement occurred in the ginseng group compared to baseline (p<0.0001); however, amitriptyline treatment resulted in a significantly greater improvement (p<0.05). Ginseng reduced the number of tender points and improved patients quality of life, as evaluated by the FIQ, compared to baseline in both cases (p<0.0001); however, no difference was found between the groups. Treatment with ginseng resulted in an improvement in all the parameters evaluated compared to baseline; however, there was no difference between this group of patients and those using placebo and amitriptyline, and this one was more effective than placebo or ginseng in improving anxiety. The beneficial effect on all parameters evaluated suggests that further studies should be performed with larger sample sizes and/or higher doses of ginseng to evaluate this herb for future use as a complementary therapy for fibromyalgia. / A fibromialgia é uma síndrome dolorosa crônica que afeta até 5% da população mundial. Pode associar-se com distúrbios do sono, do humor e fadiga, e cursar com incapacidade funcional. Sua patogênese envolve distúrbio de modulação central da dor, comprometimento do sistema inibitório descendente e hiperatividade da substância P. O fármaco mais utilizado na sua terapia farmacológica é a amitriptilina, com melhora em até 50% dos casos. Há muito interesse dos pacientes sobre a medicina alternativa e complementar na terapia da fibromialgia. O Panax ginseng C.A. Meyer é uma erva utilizada pela medicina oriental há centenas de anos. Estudos pré-clínicos comprovaram a ação antinociceptiva dos seus metabólitos ativos (ginsenosídeos) sobre a dor induzida pela substância P, e demonstraram sua capacidade de inibir canais de cálcio nos neurônios da região dorsal medular. Ensaios clínicos sugeriram melhora da qualidade de vida e da fadiga com uso do ginseng. O estudo teve como objetivos: avaliar a eficácia terapêutica do extrato das raízes do P. ginseng no controle da dor, fadiga, qualidade do sono e ansiedade, e qualidade de vida na fibromialgia. Foram selecionadas 52 mulheres, com idades entre 21 e 60 anos, após preencherem os critérios de inclusão para o estudo. Foi desenvolvido um ensaio clínico, randômico, duplo-cego, controlado, por 12 semanas, comparando a ação do P. ginseng (100 mg/dia) com amitriptilina (25 mg/dia) e placebo. Variáveis avaliadas: dor, fadiga, qualidade do sono e ansiedade, por escala visual analógica (EVA); dor, por contagem dos pontos dolorosos; e melhora da qualidade de vida, por meio do Fibromyalgia impact questionnaire (FIQ). As pacientes foram avaliadas em 6 visitas, e os resultados foram dados em média ± EPM, utilizando ANOVA e pós-teste de Tukey. Trinta e oito mulheres concluíram o estudo, com média de idade de 43 anos. Não houve diferença significante nas características basais médias nos três grupos. Na EVA, observou-se: redução da dor no grupo do ginseng (p<0,0001), com melhora ≥ 30% a partir da 6ª semana de terapia; melhora da fadiga (p<0,0001), com redução ≥ 25% a partir da 6ª semana, e ≥ 40% na 9ª semana; e melhora do sono (p= 0,0003), reduzindo ≥ 40% a partir da 6ª semana de terapia. Nas três variáveis avaliadas na EVA, houve melhora em relação ao período basal, mas não houve diferença entre os três grupos. Com relação à ansiedade, o ginseng mostrou-se melhor em relação ao período basal (p<0,0001), mas foi inferior à amitriptilina (p<0,05), na comparação entre os grupos. O ginseng reduziu o número de pontos dolorosos e melhorou a qualidade de vida das pacientes (FIQ), ambos em relação ao período basal (p<0,0001), mas não houve diferença entre os grupos. O ginseng foi capaz de melhorar todos os parâmetros avaliados em relação ao período basal, mas não foi diferente do placebo ou da amitriptilina, e esta foi superior ao placebo e ao ginseng na melhora da ansiedade. Sua atuação benéfica nos parâmetros avaliados sugere a realização de novos ensaios clínicos, com amostras maiores, e/ou com dose maior do ginseng, para uma futura indicação como terapia complementar na fibromialgia.

abstract: There is increasing interest in the medical and behavioral health communities towards developing effective strategies for the treatment of chronic diseases. Among these lie adaptive interventions, which consider adjusting treatment dosages over time based on participant response. Control engineering offers a broad-based solution framework for optimizing the effectiveness of such interventions. In this thesis, an approach is proposed to develop dynamical models and subsequently, hybrid model predictive control schemes for assigning optimal dosages of naltrexone, an opioid antagonist, as treatment for a chronic pain condition known as fibromyalgia. System identification techniques are employed to model the dynamics from the daily diary reports completed by participants of a blind naltrexone intervention trial. These self-reports include assessments of outcomes of interest (e.g., general pain symptoms, sleep quality) and additional external variables (disturbances) that affect these outcomes (e.g., stress, anxiety, and mood). Using prediction-error methods, a multi-input model describing the effect of drug, placebo and other disturbances on outcomes of interest is developed. This discrete time model is approximated by a continuous second order model with zero, which was found to be adequate to capture the dynamics of this intervention. Data from 40 participants in two clinical trials were analyzed and participants were classified as responders and non-responders based on the models obtained from system identification. The dynamical models can be used by a model predictive controller for automated dosage selection of naltrexone using feedback/feedforward control actions in the presence of external disturbances. The clinical requirement for categorical (i.e., discrete-valued) drug dosage levels creates a need for hybrid model predictive control (HMPC). The controller features a multiple degree-of-freedom formulation that enables the user to adjust the speed of setpoint tracking, measured disturbance rejection and unmeasured disturbance rejection independently in the closed loop system. The nominal and robust performance of the proposed control scheme is examined via simulation using system identification models from a representative participant in the naltrexone intervention trial. The controller evaluation described in this thesis gives credibility to the promise and applicability of control engineering principles for optimizing adaptive interventions. / Dissertation/Thesis / M.S.

Etude longitudinale comparative de l’efficacité d’un programme cognitivo-comportemental de groupe pour l’autogestion de la fibromyalgie : 112 patients suivis en ambulatoire à l’hôpital, âgés entre 18 et 66 ans, répartis au hasard dans un bras traitement GTCC (8 séances, 2 heures par semaine) ou dans un bras témoin GTEM (1 séance, 2 heures d’information d’éducation thérapeutique) organisés en groupes de 5 à 9 patients. Tous ont répondu à des questionnaires avant l’intervention et ont été réévalués avec des tests cliniques 3, 6 et 12 mois après le traitement. Les résultats montrent : il n’y pas de différences significatives entre GTCC et GTEM. Pour GTCC nous constatons des changements significatifs : amélioration de la motivation au maintien des acquis, de la qualité de vie spécifique à la fibromyalgie, de l’état de santé général ; et diminution du coping dramatisation, de l’intensité de la douleur, de l’anxiété et de la dépressivité. La sévérité de la douleur, reste inchangée. La dépressivité et la douleur peuvent jouer un rôle prédictif du développement de facteurs cliniques. Un programme TCC pour l’autogestion de la fibromyalgie est efficace à court et long terme / A longitudinally comparative study assessed a group self-management CBT program efficacy for 112 fibromyalgia hospital outpatients, aged 18 to 66. They were andomized in treatment group GTCC (8 weekly 2 hours sessions) and reference group GTEM (one 2 hours therapeutic patient education session), both organized with 5 to 9 patients. All patients were submitted a socio-demographic data and clinical questionnaire before intervention and a clinical re-evaluation at 3, 6 and 12 months after treatment. No significant differences between GTCC and GTEM groups were found. GTCC results shows significant short and long-term improvement in motivation to maintain the new strategies, quality of life and health status; and in decreased catastrophizing coping strategies, pain intensity, anxiety and depression propensity. No change in pain severity was found. Depression and pain can predict the development of psychological and clinical factors. A fibromyalgia self-management CBT program is efficient at short and long term.
