Aim Musculoskeletal disorders are a major public health problem in most developed countries. As a main cause of chronic pain, they have resulted in an increasing prescription of opioids worldwide. With regard to the situation in Germany, this study aimed at estimating the prevalence of musculoskeletal diseases such as chronic low back pain (CLBP) and hip/knee osteoarthritis (OA) and at depicting the applied treatment patterns. - Subject and methods German claims data from the InGef Research Database were analyzed over a 6-year period (2011–2016). The dataset contains over 4 million people, enrolled in German statutory health insurances. Inpatient and outpatient diagnoses were considered for case identification of hip/knee OA and CLBP. The World Health Organization (WHO) analgesic ladder was applied to categorize patients according to their pain management interventions. Information on demographics, comorbidities, and adjuvant medication was collected. - Results In 2016, n = 2,693,481 individuals (50.5% female, 49.5% male) were assigned to the study population; 62.5% of them were aged 18–60 years. In 2016, n = 146,443 patients (5.4%) with CLBP and n = 307,256 patients (11.4%) with hip/ knee OA were identified. Of those with pre-specified pain management interventions (CLBP: 66.3%; hip/knee OA: 65.1%), most patients received WHO I class drugs (CLBP: 73.6%; hip/knee OA: 68.7%) as the highest level. - Conclusion This study provides indications that CLBP and hip/knee OA are common chronic pain conditions in Germany, which are often subjected to pharmacological pain management. Compared to non-opioid analgesic prescriptions of the WHO I class, the dispensation of WHO class II and III opioids was markedly lower, though present to a considerable extent.

Work-related musculoskeletal disorders (WMSDs) due to overexertion and consequently the low back pain (LBP) are one of the most prevalent sources of nonfatal occupational injuries and illnesses in all over the world. In the past several years, the industrial exoskeletons especially the passive ones have been proposed as alternative intervention and assistive devices, which are capable of reducing the risk of WMSDs and LBP. However, more research is warranted to validate the applicability of these exoskeletons. In addition, because the majority of previous studies have been limited to specific lifting tasks using only one type of lift assistive exoskeleton, more research is needed to examine the effect of alteration of different lift-assistive exoskeletons on reducing the activity of back muscles and metabolic reduction. The main objective of this dissertation is to render an overview of three studies that attempt to improve the literature by providing comprehensive biomechanical evaluations and metabolic assessments of three passive lift-assistive exoskeletons (VT-Lowe's Exoskeleton (developed in ARLab at VT), Laevo and SuitX). This dissertation has been composed of three related studies. The first study aimed to investigate and examine the capability of a novel lift assistive exoskeleton, VT-Lowe's exoskeleton, in reducing the peak and mean activity of back and leg muscles. Findings revealed that the exoskeleton significantly decreased the peak and mean activity of back muscles (IL(iliocostalis lumborum) and LT(longissimus thoracis)) by 31.5% and 29.3% respectively for symmetric lifts, and by 28.2% and 29.5% respectively for asymmetric lifts. Furthermore, the peak and mean EMG of leg muscles were significantly reduced by 19.1% and 14.1% during symmetric lifts, and 17.4% and 14.6% during asymmetric lifts. Interestingly, the VT-Lowe's exoskeleton showed higher reduction in activity of back and leg muscles compared to other passive lift-assistive exoskeletons available in the literatures. In the second study, the metabolic cost reduction associated with the use of VT-Lowe's exoskeleton during freestyle lifting was theoretically modelled, validated and corresponding metabolic savings were reported. The metabolic cost and the oxygen consumption results supported the hypothesis that the VT-Lowe's exoskeleton could significantly reduce the metabolic demands (~7.9% on average) and oxygen uptake (~8.7% on average) during freestyle lifting. Additionally, we presented a prediction model for the metabolic cost of exoskeleton during repetitive freestyle lifting tasks. The prediction models were very accurate as the absolute prediction errors were small for both 0% (< 1.4%) and 20% (< 0.7%) of body weight. In the third study, the biomechanical evaluation, energy expenditure and subjective assessments of two passive back-support exoskeletons (Laevo and SuitX) were examined in the context of repetitive lifting tasks. The experimental lifting tasks in this study were simulated in a laboratory environment for two different levels of lifting symmetry (symmetric vs. asymmetric) and lifting posture (standing vs. kneeling). Results of this study demonstrated that using both exoskeletons during dynamic lifting tasks could significantly lower the peak activity of trunk extensor muscles by ~10-28%. In addition, using both exoskeletons could save the energy expenditure by ~4-13% in all conditions tested by partially offsetting the weight of the torso. Such reductions were, though, task-dependent and differed between the two tested exoskeletons. Overall, the results of all three studies in this dissertation showed the capability of passive lift-assistive exoskeletons in reducing the activity of back and leg muscles and providing metabolic savings during repetitive lifting tasks. / Doctor of Philosophy / Low back pain (LBP) due to overexertion is known as one of the most important sources of nonfatal occupational injuries especially for the workers or manual material handlers who are involved in frequent or repetitive lifting tasks. Every year, many workers are temporarily or permanently disabled due to overuse injuries at workplace. In the past several years, industrial exoskeletons have gained growing interest among biomechanist, roboticist, and other human factor researchers as potential assistive devices to reduce the risk of LBP. In general, the industrial exoskeletons are either “passive or “active”; Active exoskeletons are powered by mechanical/electrical motors and actuators, however, the passive exoskeletons often work using cheaper devices such as gas or metal springs, elastic elements, etc. The exoskeletons discussed in this dissertation are categorized as passive rigid lower-back exoskeletons and they function by storing energy in a spring when the wearer bends and returning the stored energy when the wearer lifts. This dissertation consists of three studies that attempt to provide comprehensive biomechanical evaluations and metabolic assessments of three passive lift-assistive exoskeletons (i.e., VT-Lowe’s Exoskeleton, Laevo and SuitX). The first study examined the efficacy of a novel lift-assistive exoskeleton, VT-Lowe’s exoskeleton, in reducing the peak and mean activity of back and leg muscles. The results of this study demonstrated that the exoskeleton reduced the peak and mean activity of back and leg muscles for symmetric and asymmetric lifting tasks. VT-Lowe’s exoskeleton also showed higher reduction in activity of back muscles compared to other passive lift-assistive exoskeletons available in the literature. In the second study, the metabolic cost reduction with VT-Lowe’s exoskeleton was theoretically modeled and the modeling outcomes were compared to metabolic costs measurements when the exoskeleton was worn. The experimental findings of this study supported the applicability of the exoskeleton by significantly reducing the metabolic cost and oxygen uptake during the freestyle repetitive lifting tasks. Moreover, the prediction metabolic cost model of the exoskeleton showed high accuracy as the absolute prediction errors were within 1.5%. In the third study, the biomechanical evaluation, energy expenditure and subjective assessments of two passive back-support exoskeletons (Laevo and SuitX) were examined in repetitive lifting tasks. The lifting tasks of this study were simulated in a laboratory environment for two different levels of lifting symmetry (symmetric vs. asymmetric) and lifting posture (standing vs. kneeling). Findings of this study showed that both exoskeleton significantly lowered the peak activity of back muscles during the dynamic lifting tasks. Moreover, using both exoskeletons provided metabolic cost savings in all of the studies conditions. Overall, results obtained from the three studies in this dissertation verified the capability of these passive lift- vi assistive exoskeleton in reducing the activity of back and leg muscles and providing the metabolic savings during repetitive lifting tasks.

With the advancement of technology, innovative control measures have been introduced to mitigate the risk of work-related musculoskeletal disorders (WMSDs). Among these measures, wearable passive exoskeletons have emerged as promising solutions for addressing WMSDs. Previous studies have demonstrated the effectiveness of wearable passive exoskeletons for improving awkward postures and reducing muscle workload in tasks involving neck extension, limbs, and back. However, the effectiveness of newly developed industrial exoskeletons designed for neck flexion remains uncertain. This study aimed to evaluate the neck exoskeleton's effects on muscle activities and work postures, by comparing the working conditions of floor workers wearing and not wearing these devices. Six subjects were recruited for field measurements. Muscle activity of the neck extensors, as well as the forward inclination angle of the head and trunk, were assessed during the measurements. Data comparison between wearing and not wearing the neck flexion exoskeleton was conducted using the related samples Wilcoxon signed-rank test. Spearman’s rank correlation coefficient was utilized to analyze the correlation between different parameters while wearing the neck flexion exoskeleton. The results showed that compared to not wearing the exoskeleton, wearing the neck flexion exoskeleton significantly reduced muscular activity at the 10th percentile (p=0.028), 50th percentile (p=0.028), and 90th percentile (p=0.028). Wearing the neck flexion exoskeleton also reduced the 10th percentile (p=0.028) and 90th percentile (p=0.046) of the head angle, and the neck angle at the 50th percentile (p=0.028) and 90th percentile (p=0.028). Additionally, the trunk angle was significantly higher with the exoskeleton at the 50th percentile (p=0.046) and 90th percentile (p=0.027). The correlation analysis when wearing the exoskeleton revealed a negative correlation between neck angle and trunk angle at the 10th percentile (r=-0.829, p=0.021). Additionally, a significant negative correlation was found between neck angle and trunk angle at the 90th percentile (r=-0.943, p=0.002), as well as between head angle and trunk angle at the 90th percentile (r=-0.829, p=0.021). Moreover, a strong negative correlation was observed between RMS and head angle at the 50th percentile (r=-0.771, p=0.036) and 90th percentile (r=-0.829, p=0.021). In conclusion, the results show that wearing neck flexion exoskeletons during actual work tasks among floor layers reduces neck extensor muscle activity, excessive neck flexion, and forward head inclination, and it may lead to an increase in forward trunk inclination, without influencing work efficiency. / trätt som en möjlighet för att minska risken för WMSD. Tidigare studier har visat att bärbara passiva exoskelett är effektiva för att minska belastningen vid besvärliga arbetsställningar och minska muskelbelastningen vid arbetsuppgifter som involverar nackextension, extremiteter och rygg. Dock är effektiviteten av nyligen utvecklade industriella exoskelett designade för nackflexion fortfarande osäker. Denna studie syftade till att undersöka effekten av ett nackflexionsexoskelett, med avseende på muskelbelastning och arbetsställningar hos golvarbetare. Sex försökspersoner rekryterades för fältmätningar. Muskelaktiviteten hos nackextensorerna, samt framåtlutningsvinkeln av huvudet och bålen, mättes under arbetet. Statistisk jämförelse mellan att bära och inte bära nackflexionsexoskelettet utfördes med hjälp av Wilcoxon signed-rank test för relaterade prover. Spearman rangkorrelationskoefficient användes för att analysera korrelationen mellan olika parametrar när nackflexionsexoskelettet bars. Resultaten visade att exoskelettet signifikant minskade muskelaktiviteten ; vid 10:e percentilen (p=0.028), 50:e percentilen (p=0.028) och 90:e percentilen (p=0.028). Vidare minskade även huvudvinkeln signifikant, 10:e percentilen (p=0.028) och 90:e percentilen (p=0.046) av, liksomnackvinkelns 50:e percentilen (p=0.028) och 90:e percentilen (p=0.028). Bålvinkeln, däremot, var signifikant högre med exoskelettet både vid 50:e percentilen (p=0.046) och 90:e percentilen (p=0.027). Korrelationsanalysen avslöjade en negativ korrelation mellan nackvinkel och bålvinkel vid 10:e percentilen (r=-0.829, p=0.021) när exoskelettet bars. Dessutom var det en signifikant negativ korrelation mellan nackvinkel och bålvinkel vid 90:e percentilen (r=-0.943, p=0.002), samt mellan huvudvinkel och bålvinkel vid 90:e percentilen (r=-0.829, p=0.021) när exoskelettet bars. Dessutom observerades en stark negativ korrelation mellan muskelaktivitet och huvudvinkel vid 50:e percentilen av de båda måtten (r=-0.771, p=0.036) och vid 90:e percentilen (r=-0.829, p=0.021) när exoskelettet bars. Sammanfattningsvis visar resultaten att användning av nackflexionsexoskelett under faktiska arbetsuppgifter bland golvläggare minskar nackextensorernas muskelaktivitet, nackflexion och framåtlutning av huvudet, samt ökar framåtlutningen av av bålen utan att påverka arbetseffektiviteten.

在台灣人口逐漸老化的情況下，如何延緩勞動者退出就業市場，攸關台灣的社會保險、年金體系及照顧體系之存續，但要勞工能夠延後退休，先決條件是身體健康與否，因此勞工的健康狀況，就不僅僅是個人問題，而是台灣社會面臨的整體危機。主管職業健康的各部門，未能意識到每個政策對於整體勞動生產力，之於經濟發展和社會福利、保險的深遠影響，以致於過度聚焦於對於勞工個人影響的層面，而缺乏思考這些行動背後，對於國家整體的宏觀意義 而在執行工作時中造成肌肉骨骼系統的任何不適、困難或疼痛，更是困擾的許多歐洲的勞工，因此歐盟無不以積極的政策來干預MSD，希望能延長停留在勞動市場的期間，並說明對於雇主、勞工、政府、財政所帶來的幫助。另外透過訪談發現，台灣的物流業從業人員，所處在的工作環境，恰如文獻所提，反覆、負重、工時過長…等，時常有受傷而繼續從事工作的情形，也導致物流業流動率高、從業人員較年輕及容易成為MSD的高風險群。 因此必須從增進MSD的概念、提升勞動條件及減少因病缺勤著手。政府方面則必須建構更完整的MSD數據，並制訂讓MSD勞工留在職場的積極性勞動力市場政策以及廣辦宣導會說明MSD對我國的重要性；雇主的重要性更是不可言喻，不僅扮演第一線的觀察者，快速做出因應措施，並著手改善從業人員勞動條件，並將干預措施予以制度化；勞工則必須透過積極參與有關MSD政策或方案的討論，更重要的是養成並維持良好的生活方式的習慣。 / Taiwan population is rapidly aging. How to persuade workers to delay withdrawing from employment market becomes an urgent challenge because this concern has significant implications to our social insurance, the annuity system and healthcare system. Therefore, the health of workers is not just a personal issue, but a public concern that everyone in this society needs to face. Government officials in charge of healthcare policy are not yet aware of its profound impact on labor productivity, economic development, social welfare and social insurance. Policy wise, we put too much attention on individual health promotion while lose sight of its macro impact. MSD, either caused by work or gene, inflicted many European workers, so that the EU actively deal with this issue with the hope that workers are able to stay longer around the labor market as long as possible. This study finds through the interview that workers of the logistics industry in Taipei endure heavy work-load, long working time, and often time have high rate of presenteeism (the tendency of workers to go to work when they are ill enough to stay at home), causing the logistics industry to have not only high exit rate but also high risk of MSD. Therefore, we have to promote the MSD concept, improve labor conditions and reduce presenteeism. For example employers have to include MSD into their pre-employment training courses for those new entrants, to reduce the hours of working time and to decrease presenteeism through providing subsidy to those who suffer from MSD. The government then has to build up a more complete MSD database, and introduces the concept of MSD and its preventive practice through seminars or workshops. Employers have key roles and duty in this issue. Specifically, they have to adopt as well as carry out preventive measures, and take quick actions whenever incidence of MSD occurs in the frontline of workplace. In addition, they have to improve working conditions and institutionalize those intervention measures. Workers then need to actively participate in MSD policy discussion other than maintaining a healthy life style. Workers, employers, health care system and social welfare system have a cause to this joint effort in keeping workers in Taiwan as healthy as possible so that every nationals can Fit For Work.

Malgré des années de recherches sur la douleur et les incapacités chroniques, peu de conclusions claires émergent quant aux facteurs de risque les plus pertinents. La majorité des auteurs s’entendent toutefois sur un fait, les troubles musculo-squelettiques et l’adaptation à leurs nombreuses conséquences est un processus complexe, multidimensionnel et déterminé par l’interaction de facteurs biopsychosociaux. Deux articles sont présentés avec comme objectifs généraux d’identifier les déterminants importants de l’ajustement à un trouble musculo-squelettique. Le premier article consiste en une recension des écrits systématique visant à résumer tous les facteurs pronostiques biopsychosociaux de l’ajustement multidimensionnel aux troubles musculo-squelettiques et examinant leur pertinence à déterminer ces divers indicateurs d’ajustement, principalement la participation au travail, les limitations fonctionnelles, la douleur, la qualité de la vie, la détresse psychologique et la rechute. Les 105 études prospectives recensées et correspondant aux critères d’inclusion et d’exclusion ont été analysés et chaque association significative a été résumée. Par la suite, 68 études qui ont inclus des facteurs sociodémographiques, biologiques, psychologiques et sociaux ont été analysées séparément. Leur qualité méthodologique a été évaluée, un niveau d’évidence a par la suite été établi pour chaque association entre les facteurs de risque et les diverses variables de résultats. Les divergences dans ces associations entre les différentes phases de chronicité ont également été identifiées. Un niveau d’évidence élevée a été découvert concernant le rôle des attentes de rétablissement, certaines pratiques de gestion intégrées de l’incapacité, les stratégies d’adaptation (coping), la somatisation, la comorbidité, la durée de l’épisode symptomatique et un niveau modéré d’évidence a été découvert pour les comportements de douleur. Lorsque vient le temps de prédire les divers indicateurs d’ajustement de sujets souffrant de troubles musculo-squelettiques, chacun tend à être associé à des facteurs de risque différents. Peu de différences ont été relevées lorsque les phases de chronicité ont été prises en compte. Ces résultats confirment la nature biopsychosociale de l’ajustement aux troubles musculo-squelettiques bien que les facteurs psychosociaux semblent être prédominants. Le second article est une étude prospective avec un suivi de 2 et 8 mois. Elle a été menée auprès de 62 travailleurs accidentés, principalement en phase de chronicité et prestataires d’indemnités de revenu de la CSST (Commission en Santé et Sécurité du Travail du Québec). L’objectif de cette étude était d’identifier les déterminants de l’engagement actif dans un processus de retour a travail par opposition à l’incapacité chronique, tout en adoptant une approche biopsychosociale. Cet objectif a été poursuivi en faisant l’étude, d’une part, de la pertinence de facteurs de risque ayant déjà fait l’objet d’études mais pour lesquelles aucun consensus n’est atteint quant à leur utilité prédictive et d’autre part, de certains facteurs de risque négligés, voire, même omis de ce domaine de recherche. Suite à des analyses multivariées, le genre, les attentes de rétablissement en terme de capacité à retourner au travail et l’importance du travail ont été identifiés comme des déterminants de l’incapacité chronique liée au travail. Après 8 mois, l’âge, la consolidation médicale, les symptômes traumatiques, le support au travail et l’importance du travail ont été également identifiés comme des déterminants d’incapacité chronique liée au travail. Ces résultats démontrent l’importance d’aborder l’étude de l’incapacité chronique et de la réinsertion professionnelle selon une perspective multidimensionnelle. Ces résultats corroborent également les conclusions de notre recension des écrits, puisque les facteurs psychosociaux ont été identifiés comme étant des déterminants importants dans cette étude. / Despite years of research on chronic pain and disability, there is yet little consensus on a core set of risk factors. One thing that most agree on, is the fact that musculoskeletal disorders and the adjustment to its consequences is a complex, multidimensional process determined by biopsychosocial factors interacting with one another. Two articles are presented with the overall goal of identifying significant determinants of adjustment to musculoskeletal disorders. The first article is a systematic literature review that aimed at reviewing all pertinent biopsychosocial prognostic factors of adjustment to musculoskeletal disorders and assessed their relevance in predicting multidimensional outcomes, namely work participation, functional disability, pain, quality of life, psychological distress and recurrence. The 105 prospective studies identified and fitting the inclusion and exclusion criteria were analyzed and all significant associations were summarized. Then, 68 studies that included sociodemoraphic and biopsychosocial risk factors were separately analysed for their methodological quality, level of evidence (LOE) was established for each association between risk factors and outcome variables and existing differences were highlighted between phases of chronicity. Strong evidence was found for recovery expectations, coping, somatization, comorbidity, duration of episode, disability management and moderate evidence was found for pain behaviours. When it comes to predicting different outcomes reflecting the adjustment process of subjects with musculoskeletal disorders, each tends to have a different set of predictors. Few significant differences were found according to phases of chronicity. These results support the biopsychosocial nature of the adjustment to musculoskeletal disorders with a predominance of psychosocial determinants. The second article is a prospective study with follow-ups at 2 and 8 months and was conducted on a sample of 62 mostly chronic occupationally injured workers receiving compensation benefits from the CSST (Quebec Workers’ Compensation Board). The study aimed to identify determinants of active involvement in a return to work process while adopting a biopsychosocial approach. It did so by investigating the pertinence of previously studied risk factors but for which no consensus yet exists, but also by investigating the pertinence of previously neglected or even omitted risk factors. After multivariate analysis, gender, work recovery expectations and importance of work were predictive of work outcomes at 2 months. After 8 months, age, medical consolidation, trauma symptoms, work support and importance of work predicted work outcomes. The results show the importance of approaching chronic work disability from a multidimensional perspective, although corroborating our literature review’s findings that psychosocial variables appear to be more significant predictors in this study.

Introduction La santé est considérée comme un idéal, un objectif et un but à atteindre; pour l'améliorer, certains ergothérapeutes utilisent les approches habilitantes. Ces dernières démontrent des résultats positifs pour la prévention des troubles musculosquelettiques (TMS). Objectif L’objectif de cette recherche est de mesurer les effets d'un programme en partenariat pour la prévention des TMS dans une pharmacie communautaire. Méthodologie Un devis mixte (quantitatif, qualitatif et descriptif) avant-après avec un groupe témoin non équivalent est utilisé. Le recrutement des participants se fait sur une base volontaire. Ceux-ci sont âgés de 18 ans et plus (groupe expérimental (n = 18) et témoin (n = 17)) et occupent trois titres d'emplois distincts. Différentes mesures via des questionnaires et des entrevues sont prises avant et après l’intervention. L’intervention, quant à elle, comprend trois rencontres élaborées à partir des concepts de l’ergonomie. Résultats En lien avec les connaissances acquises et la mobilisation, une diminution des sensations douloureuses est constatée chez les participants du groupe expérimental. De même, pour ceux-ci, une tendance à la généralisation des connaissances est notée. Conclusion Inspirée des principes de la prévention, de l’ergonomie et de l’habilitation, cette recherche, malgré ses limites, permet de mieux documenter les effets d'un programme en partenariat en entreprise de services pour la prévention des TMS. / Introduction Health is regarded as an ideal, a goal to improve and to achieve; in order to enhance it some therapists using enabling approaches. The latter show positive results for the prevention of musculoskeletal disorders (MSD's). Objective The objective of this research is to measure the effects of a partnership program in a community pharmacy for the prevention of MSD's. Methodology A mixed design (quantitative, qualitative and descriptive) before and after with a non-equivalent control group is used. Participant recruitment is done on a voluntary basis. They are aged 18 years and over (experimental group (n = 18) and control (n = 17)) and occupy three distinct job titles. Different measures through questionnaires and interviews are taken before and after the intervention. The intervention, meanwhile, includes three session developed from the concepts of ergonomics. Results Results are related to the acquired knowledge and mobilization, and there is a decreased of pain sensation is measured among the participants of the experimental group. Similarly, for these participants, a disposition or proneness to generalize knowledge is observed. Conclusion Inspired by the principles of prevention, ergonomics and empowerment, this study, despite its limitations, allows to better document the effects of a program in partnership with business services for MSD's prevention.

Les troubles musculo-squelettiques du membre supérieur (TMS-MS) peuvent avoir un impact négatif sur l'autonomie d’une personne. À ce jour, il n’existe pas d’outils en français évaluant les limitations d'activités et les restrictions de participation, disposant de bonnes propriétés métrologiques et d'applicabilité dans un contexte clinique marqué par des contraintes de temps. L’Upper Limb Functional Index (ULFI), qui présente de bonnes qualités métrologiques et applicabilité clinique adéquate, s'avère un outil intéressant pour les ergothérapeutes de par son approche centrée sur la personne. Toutefois, il n'était disponible qu'en anglais et en espagnol. La présente recherche, constituée de deux études, visait à adapter l’ULFI à la population canadienne française et à évaluer ses propriétés métrologiques et son applicabilité clinique. La première étude a examiné sa cohérence interne, sa validité convergente et son applicabilité clinique auprès de 50 patients bilingues atteints de TMS-MS. La seconde étude visait à analyser sa fidélité test-retest et sa sensibilité au changement auprès de 60 patients francophones. Les résultats ont révélé que l'ULFI-CF possède des propriétés métrologiques solides : une cohérence interne élevée (α de Cronbach = 0,93), une excellente fidélité test-retest (CCI = 0,87-0,95), une excellente validité convergente (r = 0,70-0,85) et une sensibilité au changement de bonne à excellente (tailles d'effet = 0,49-0,88 et r = 0,64 pour la section 1). L'ULFI-CF démontre également une bonne applicabilité clinique. En conclusion, l’ULFI-CF s’avère un outil pertinent pour les cliniciens œuvrant auprès d’une clientèle canadienne française souffrant d'un TMS-MS dans un contexte clinique marqué par des contraintes de temps. / Upper limb musculoskeletal disorders (UL-MSD) can negatively impact on patients' autonomy. There are no existing outcome measures available in French to assess activity limitations and participation restrictions caused by UL-MSD that have sound metrological properties and are applicable in a clinical context where clinicians have limited assessment time for each patient. The Upper Limb Functional Index (ULFI), having good metrological qualities and clinical applicability, is a relevant tool for clinicians since it promotes a patient-centered approach. However, the tool was only available in English and Spanish until now. This research project included two studies and aimed at adapting the ULFI to the French Canadian population and to assess the metrological properties of the adapted version (ULFI-FC) and its clinical applicability. The first study examined its internal consistency, convergent validity and clinical applicability among 50 bilingual patients with UL-MSD. The second study aimed to analyse its test-retest reliability and responsiveness among 60 French-speaking patients. The findings revealed that the ULFI-FC possesses sound metrological properties: a high internal consistency (Cronbach α = 0.93 for Part 1), an excellent test-retest reliability (ICC = 0.87-0.95), an excellent convergent validity (r = 0.70-0.85), and good to excellent responsiveness (effect size = 0.49-0.88; and r = 0.64 for Part 1), as well as good clinical applicability in a context where assessment time devoted to each patient is limited. In conclusion, the ULFI-CF is a relevant and attractive tool assessing activity limitations and participation restrictions for clinicians working with French Canadian UL-MSD patients in a busy clinical setting.

INTRODUÇÃO: Os trabalhadores dos Serviços de Nutrição Hospitalar são submetidos às exigências físicas, cognitivas e psíquicas que levam à distúrbios osteomusculares relacionados ao trabalho. O objetivo deste estudo foi implantar ações de melhorias nas situações de trabalho de um serviço de nutrição hospitalar e avaliar a percepção dos trabalhadores e as repercussões sobre os sintomas osteomusculares. MÉTODO: Esta pesquisa foi desenvolvida em um hospital público especializado em cardiologia, localizado em São Paulo, Brasil, após aprovação pelo comitê de ética da instituição. A coleta de dados foi realizada por meio da aplicação de questionários e análise ergonômica do trabalho. Os questionários continham dados sócio-demográficos, história ocupacional, situação de trabalho atual, sintomas osteomusculares e satisfação no trabalho. Do total de 130 trabalhadores, 115 participaram voluntariamente. A análise ergonômica do trabalho foi efetuada de acordo com Guérin et al (2001), sendo realizadas entrevistas, medições do ambiente da cozinha e análises biomecânicas. A partir dos resultados foram implantadas ações de intervenção baseadas na ergonomia participativa durante um ano. Após esta fase, 89 (77%) trabalhadores responderam novamente ao questionário, sendo incluídas perguntas sobre a percepção das modificações. A análise dos dados incluiu testes estatísticos para verificar se houve mudança da prevalência de sintomas antes e após as intervenções, com nível de significância de 5%, por meio dos Programas SPSS 13.0 e Excel 2003. Além disso, foram analisados os dados de percepção dos trabalhadores e dos especialistas em ergonomia sobre o impacto das melhorias na saúde e no processo de trabalho. RESULTADOS: A população constitui-se, em sua maioria, por mulheres, na faixa etária de 25 a 34 anos, com grau médio de escolaridade, casadas, com filhos, e ocupavam o cargo de atendente de nutrição. A maioria trabalhava de 5 a 10 anos no hospital e em jornada de trabalho de 40 horas semanais. Os principais problemas observados foram espaço físico reduzido, equipamentos e materiais de trabalho inadequados, absenteísmo e déficit de pessoal, volume excessivo de trabalho com elevado esforço mental, alta prevalência de sintomas osteomusculares, principalmente nos membros inferiores e ombros. Após as intervenções realizadas, houve melhoria na situação de trabalho com redução nos sintomas osteomusculares e os trabalhadores perceberam as seguintes mudanças nas situações de trabalho: melhoria na iluminação e no controle do ar condicionado, aquisição de batedeira de tamanho médio, conserto de equipamentos, substituição dos pratos de vidro por descartáveis, aquisição de cadeiras, introdução de pausas durante a jornada de trabalho, ginástica laboral e treinamento em liderança para as chefias. Neste período houve ampliação no número de leitos do hospital com conseqüente aumento no volume de trabalho e diminuição da satisfação no trabalho associados à crise financeira da instituição com suspensão de contratações e da compra de materiais e equipamentos. CONCLUSÕES: As intervenções repercutiram em melhorias, principalmente quanto ao ambiente e equipamentos, e na redução dos sintomas osteomusculares nos membros inferiores, ombros, pescoço/região cervical, antebraço e região lombar, apesar desta redução não ter sido estatisticamente significativa. / INTRODUCTION: Hospital food service workers have high level of physical, cognitive and mental demands that are associated with musculoskeletal disorders. The objective of this study was to introduce improvements in the working conditions in a hospital food service and to evaluate the workers perceptions and its effects on musculoskeletal symptoms. METHOD: this study was performed in a public cardiac hospital in São Paulo, Brazil, after its approval by the Ethics Committee. The data were collected by questionnaires and ergonomic analysis of the work. The questionnaire included: socio-demographic, workhistory, work conditions, musculoskeletal symptoms and job satisfaction. A hundred and fifteen questionnaries were applied from 130 workers. The work ergonomic analysis was carried out in accordance with Guérin et al (2001), by means of interviews, observations of kitchen working conditions and biomechanical analyses. Based on the results, interventions have been undertaken by means of a participatory ergonomic approach over one year. After this, another ergonomic analysis was carried out and 89 workers (77%) answered a new questionnaire that also included questions about their perception of the improvements. Data analysis was done by statistical tests to verify symptom prevalences before and after the interventions with a 5% level of significance. SPSS 13.0 and Excel 2003 software was used. RESULTS: The workers were women in the 25-34 age-group, had secondary education, were married, had children and occupied the position of nutrition attendants. They were in this hospital for from 5 to 10 years and on a 40 hour working week schedule. Most of problems observed were reduced space, inadequate equipment and work materials, absenteeism, insufficient number of workers, great volume of work with mental demands, high prevalence of musculoskeletal symptoms mainly in lower members and shoulders. After the improvements in working conditions, the symptoms of musculoskeletal disorders reduced and the workers perceived the following changes in the work process: better lighting and control of air conditioning, acquisition of low capacity mixer, repair of equipment, use of disposable utensils instead of glass plates, acquisition of more chairs, introduction of breaks during working hours, work related gymnastics, workshops for leadership training. In this period the number of hospital beds was increased with a corresponding intensification of the work load and a decline on job satisfaction. The hospital was in a financial crisis with consequences in terms of the hiring of personnel and the acquisition of equipment and materials. CONCLUSION: Interventions brought improvements mainly as regards the work environment and equipment and in the reduction of musculoskeletal symptoms in the lower members, shoulders, neck/cervical region, forearm and lumbar region, though this reduction has not been statistically significant.

O presente estudo nasce da necessidade de melhorar a integralidade da atenÃÃo à saÃde dos trabalhadores, destacando o trabalhador com lesÃes por esforÃos repetitivos e distÃrbios osteomusculares relacionados ao trabalho - LER/DORT. Assim tivemos como objetivo construir participativamente uma linha de cuidado integral para o trabalhador com LER/DORT no Ãmbito do SUS a partir da experiÃncia dos profissionais, gestores e usuÃrios que compÃem as redes de atenÃÃo à saÃde. Desenvolvida no municÃpio de Sobral- CearÃ, esta pesquisa à de natureza qualitativa do tipo exploratÃria. A pesquisa aÃÃo foi a metodologia de escolha por constitui-se como uma metodologia que visa à aÃÃo e promove a capacidade de transformaÃÃo da realidade pelos sujeitos da pesquisa. Para tal, utilizamos a pesquisa em grupo, onde os participantes, profissionais das redes de atenÃÃo à saÃde de Sobral, foram os responsÃveis pela construÃÃo da linha de cuidado em um processo que levou à formulaÃÃo, dos fluxos e atribuiÃÃes que os prÃprios participantes da pesquisa e seus pares deverÃo desenvolver nos serviÃos em que trabalham com o objetivo de promover a integralidade da atenÃÃo à saÃde do trabalhador. Ressaltamos que estas aÃÃes da linha de cuidado foram construÃdas no ano de 2012 coletivamente, apÃs quatro encontros do grupo. O primeiro encontro foi para debater sobre integralidade e definir as aÃÃes prioritÃrias apontadas pelo grupo, o segundo encontro foi uma oficina que teve como objetivo construir o fluxo da linha de cuidado, o terceiro encontro a segunda oficina que teve como objetivo definir as atribuiÃÃes dos profissionais dos serviÃos que atendem o trabalhador, e o quarto encontro, e Ãltima oficina, tiveram como objetivos apresentar o fluxo construÃdo pelo grupo e validar as atribuiÃÃes da rede de serviÃos que atende o trabalhador com LER/DORT. Como mÃtodo de tratamento dos dados obtidos utilizamos a anÃlise do discurso. Os resultados apontam que trabalhadores com a doenÃa podem buscar diversos pontos da rede de atenÃÃo, dentre eles serviÃos da AtenÃÃo Primaria a SaÃde, da AtenÃÃo Ambulatorial Especializada, da AtenÃÃo Hospitalar e da UrgÃncia e EmergÃncia. Surgiram apÃs a validaÃÃo 36 atribuiÃÃes para os profissionais. As atribuiÃÃes identificadas incluÃram aÃÃes promocionais, preventivas, curativas e de reabilitaÃÃo. Ressaltamos que para construir a linha de cuidado pensamos na necessidade do trabalhador como o aspecto central para seu fluxo de atendimento e assistÃncia. Dessa forma, a linha de cuidado proposta demonstra uma possibilidade da garantia da integralidade relacionada à organizaÃÃo dos serviÃos de saÃde, mostrando o caminho a ser percorrido por um usuÃrio, desde a APS e passando por diferentes serviÃos na busca de um leque de cuidados necessÃrios para resolver seu problema de saÃde. Para o funcionamento da linha de cuidado proposta à necessÃrio à existÃncia de um trabalho compartilhado entre os profissionais da APS e os demais serviÃos de saÃde. Nesse processo, alÃm da construÃÃo e pactuaÃÃo do fluxo da atenÃÃo, à necessÃrio a elaboraÃÃo de estratÃgias para efetivar esse caminho a ser percorrido pelo trabalhador na rede de atenÃÃo, estabelecer e negociar responsabilidades para garantir a qualidade e continuidade do cuidado.

Introdução: O Código de Processo Civil determina que nos processos judiciais em que a matéria depender de conhecimento técnico ou científico, o juiz será assistido por perito, que produzirá um laudo. Foram analisados 83 laudos de processos judiciais do Tribunal Regional do Trabalho da 2ª Região (TRT-2), referentes a reclamantes com Lesões por Esforços Repetitivos ou Distúrbios Osteomusculares Relacionados ao Trabalho (LER/Dort), que abrangem afecções crônicas do sistema musculoesquelético de origem ocupacional e são decorrentes, dentre outros motivos, da execução de movimentos repetitivos por tempo prolongado e sobrecarga estática, sem que haja tempo para uma recuperação fisiológica. Deveriam abordar os vários aspectos do adoecimento para auxiliar a decisão judicial quanto à existência de agravo à saúde relacionado ao trabalho, assim como sua extensão e repercussões sobre a vida e capacidade laboral do trabalhador. Objetivos: Identificar e analisar, nos laudos, conceitos sobre adoecimento ocupacional e incapacidade laboral, bem como as principais linhas de argumentação, para a descaracterização do nexo causal nos casos em que havia nexo causal presumido pelo critério epidemiológico. Material e método: O material de estudo (83 laudos) foi buscado dentre os processos arquivados no período de 2012 a 2016 na Coordenadoria de Gestão de Arquivo do TRT-2, que abrange 30 municípios da região metropolitana de São Paulo e Baixada Santista. Atributos associados aos grandes temas da pesquisa foram codificados com o objetivo de melhor sistematização para uma análise de conteúdo. Resultados: Os laudos periciais foram elaborados, na sua quase totalidade por médicos, dentre os quais 56 (67,47%) médicos do trabalho, 13 (15,66%) médicos sem especificação de especialidade, 9 (10,84%) médicos com especialização em perícia ou legistas e 4 ortopedistas (4,82%). Um deles (1,21%) foi elaborado por fisioterapeuta. Do total de laudos, 25 (30,12%) não tinham quaisquer informações sobre o processo de adoecimento e apenas 23 (27,71%) contemplaram uma história clínica abrangente. Em 34 (40,96%) não havia qualquer informação sobre as características da atividade de trabalho e em 30 (36,15%) havia a citação de alguns aspectos biomecânicos. Apenas 19 (22,89%) apresentaram uma análise da atividade de trabalho, incluindo aspectos biomecânicos e organizacionais. Nenhum laudo continha uma análise da incapacidade para o trabalho de forma ampla, sendo que em 50 laudos (60,24%), o perito considerou apenas o diagnóstico para se pronunciar sobre a incapacidade. Do total dos laudos, apenas 13 (15,66%) utilizaram o conceito de multicausalidade e 12 (14,46%) o de concausalidade. Dos 15 laudos com nexo causal presumido pelo critério epidemiológico, descaracterizados no caráter ocupacional na perícia, nenhum continha uma análise da atividade de trabalho, embora 9 deles tenham utilizado argumentos biomecânicos, 8 tenham utilizado o argumento de que se tratava de doença degenerativa e 3 de que o quadro era de fibromialgia não ocupacional. Foram discutidos conceitos de adoecimento ocupacional, nexo causal e incapacidade, além da relação de desigualdade, presenteísmo, individualização do adoecimento e culpabilização. Conclusão: A maioria dos laudos periciais peca pela falta de consistência conceitual, metodológica e argumentos fundamentados, deixando lacunas na área clínica, na análise da atividade de trabalho e na avaliação de incapacidade. / Introduction: The Civil Code Procedure determines that in judicial proceedings in which the matter depends on technical or scientific knowledge, the judge will be assisted by experts, who will produce a forensic report. A total of 83 reports, from the Regional Labor Court of the 2nd Region (TRT-2), were analysed, concerning claimants suffering from Repetitive Strain Injury or Work-Related Musculoskeletal Disorders (RSI/WRMD), which include occupational chronic conditions of the musculoskeletal system, that are due, among other reason to the execution of repetitive movements for a prolonged time and static overload without pause foa a physiological recoevery. They should address the various aspects of illness in order to assist the judge in his decision regarding the existence of as aggravated health related to work, as well as its extent and repercussions on the life and work capacity of the worker. Objectives: To identify and analyse concepts about occupational illness and disability to work, expressed in the reports, as well as the main lines of argument, for the de-characterization of the causal nexus in cases where there was causal nexus presumed by the epidemiological criterion. Material and method: The study material was searched from the archived processes from 2012 to 2016 in the File Management Coordination of TRT-2, which covers 30 municipalities in the metropolitan region of São Paulo and Baixada Santista. Attributes associated with the major themes of the research were codified with the aim of better systematization for a content analysis. Results: The expert reports were elaborated almost entirely by physicians, among them 56 (67.47%) occupational physicians, 13 (15.66%) doctors without a declared specialty, 9 (10.84%), forensic doctors, 4 orthopedists (4,82%). One of the reports (1.21%) was elaborated by a physiotherapist. Of the total reports, 25 (30.12%) did not have information about the illness process and only 23 (27.71%) contemplated a comprehensive medical history. In 34 (40.96%) there was no information about the characteristics of the work activity and in 30 (36.15%) there were citation of some biomechanical aspects. Only 19 (22.89%) presented an analysis of the work activity, including biomechanical and organizational aspects. No report contained an embrancing analysis of disability to work comprehensively, and in 60.24% of them, the expert considered only the diagnosis to pronounce on the disability. Of the total reports, only 13 (15.66%) used the concept of multicausality and 12 (14.46%) the concept of concausality. Of the 15 reports with a presumed causal nexus by the epidemiological criterion, which were not characterized in the occupational character, none contained an analysis of the work activity, although 9 of the 15 reports used biomechanical arguments to de-characterize the occupational character, 8 used the argument that it was degenerative disease and 3 that the condition was non-occupational fibromyalgia. Concepts of occupational illness, causal nexus and disability were discussed, as well as the relationship of inequality, presenteism, individualization of illness and blame. Conclusions: Most of the expert reports are lacking in conceptual, methodological and reasoned arguments, leaving relevant gaps in the clinical area, in the analysis of the work activities and in the assessment of disability.
