Les charges excessives imposées sur la colonne vertébrale lombaire constituent un facteur de risques important pour les maux de dos. La modélisation biomécanique de la colonne vertébrale est la seule approche non invasive permettant d’estimer ces charges, mais la complexité de ces modèles limite leur utilisation par des ergonomes. Pour aider ces derniers à identifier des situations à risque de blessures au dos afin de limiter le chargement aux structures lombaires, il existe des outils d’aide à la décision comme l’équation de levage du NIOSH (Revised NIOSH Lifting Equation, Waters et al., 1993) ainsi que les tables …

Structural Remodeling Of The Lumbar Multifidus, Thoracolumbar Fascia And Lateral Abdominal Wall Perimuscular Connective Tissues: Medium-Term Test-Retest Reliability Of Ultrasound Measures, Christian Larivière, Dany H. Gagnon, Richard Preuss
Études primaires
Abstract
Introduction
Growing interest is being paid to the lumbar multifidus (LM) intramuscular fatty infiltrations and fibrosis that are secondary to low back pain as well to the remodeling of perimuscular connective tissues (fasciae) such as the thoracolumbar fascia and fascia sheets separating the abdominalwall muscles. Magnetic resonanceimaging and computed tomography have traditionally been used but rehabilitative ultrasound imaging (RUSI) is much more affordable and practical, which can accelerate research and clinical applications on this topic. The aim of this study was to test the medium-term (8 weeks) test-retest reliability of the corresponding RUSI measures.

Rapports de recherche scientifique
Environ une personne sur trois dans le monde vivrait avec un trouble musculosquelettique (TMS) persistant. Plusieurs auteurs soulignent l’influence significative des facteurs psychosociaux, dont l’anxiété, sur le développement de l’incapacité prolongée. Associées à l’anxiété, des inquiétudes excessives ont été documentées chez des travailleurs ayant une douleur persistante d’origine musculosquelettique. Les inquiétudes ne favorisent pas l’adaptation en contexte d’une situation problématique. Cependant, aucune étude n’a jusqu’à présent tenté de comprendre ces inquiétudes, en lien avec l’environnement de travail. Une meilleure compréhension de ce phénomène semble un incontournable pour offrir une action mieux ciblée aux travailleurs ayant une incapacité au travail prolongée. …

L’atteinte de troubles musculosquelettiques (TMS) parmi les travailleurs et travailleuses au Québec était récemment estimée à 732 000 cas (Stock et al., 2014). Ces TMS sont associés aux activités professionnelles impliquant des efforts physiques prolongés, intenses et/ou répétitifs, telles que des tâches d’assemblage, de manutention, d’aide à la personne ou encore de maintien de posture prolongée sur un poste de travail. Les membres supérieurs, qui représentaient 30,1 % des cas de TMS déclarés et acceptés au Québec de 1998 à 2007 (Michel et al., 2010), sont les plus touchés après le dos. Plus particulièrement, l’épaule figure comme l’articulation …

Études primaires
Purpose:Lack of adherence to home exercise programmes is hypothesised to partially explain the modest clinical effects seen in patients with low back pain. This study explored the association between the main biopsychosocial factors and adherence using a theory-driven approach including the fear-avoidance model, the common-sense model and the working alliance concept.
Methods: A repeated measures design was used. During and after an eight-week clinical exercise programme, 48 participants with non-acute and disabling low back pain followed a home exercise programme. Questionnaires assessed home exercise adherence and biopsychosocial factors at baseline, after the eight-week clinical programme and at the six-month follow-up. …

Études primaires
Maximum voluntary exertion (MVE) tasks quantify trunk strength and maximal muscle electromyography (EMG) activities with both clinical and biomechanical implications. The aims here are to evaluate the performance of an existing trunk musculoskeletal model, estimate maximum muscle stresses and spinal forces, and explore likely differences between males and females in maximum voluntary exertions. We, therefore, measured trunk strength and EMG activities of 19 healthy right-handed subjects (9 females and 10 males) in flexion, extension, lateral and axial directions. MVEs for all subjects were then simulated in a subject-specific trunk musculoskeletal model, and estimated muscle activities were compared with EMGs. Analysis …

Trunk Postural Adjustments: Medium-Term Reliability And Correlation With Changes Of Clinical Outcomes Following An 8-Week Lumbar Stabilization Exercise Program, Jean-Alexandre Boucher, Richard Preuss, Sharon M. Henry, Marilee Nugent, Christian Larivière
Études primaires
Background
Low back pain (LBP) has been previously associated with delayed anticipatory postural adjustments (APAs) determined by trunk muscle activation. Lumbar stabilization exercise programs (LSEP) for patients with LBP may restore the trunk neuromuscular control of the lumbar spine, and normalize APAs. This exploratory study aimed at testing the reliability of EMG and kinematics-based postural adjustment measures over an 8-week interval, assessing their sensitivity to LBP status and treatment and examining their relationship with clinical outcomes.
Methods
Muscle activation of 10 trunk muscles, using surface electromyography (EMG), and lumbar angular kinematics were recorded during a rapid arm-raising/lowering task. Patients with …
