Prediction models to identify workers at risk of sick leave due to low-back pain in the Dutch construction industry
Objective: The aim of this study was to develop a prediction model based on variables measured in occupational health checks to identify non-sick listed workers at risk of sick leave due to non-specific low-back pain (LBP). Methods: This cohort study comprised manual (N=22 648) and non-manual (N=9735) construction workers who participated in occupational health checks between 2010 and 2013. Occupational health check variables were used as potential predictors and LBP sick leave was recorded during 1-year follow-up. The prediction model was developed with logistic regression analysis among the manual...
Revised NIOSH Lifting Equation May generate spine loads exceeding recommended limits
The 1991 NIOSH Lifting Equation (NLE) is widely used to assess the risk of injury to spine by providing estimates of the recommended weight limit (RWL) in hands. The present study uses the predictive equations developed based on a detailed trunk musculoskeletal biomechanical model to verify whether the RWL generates L5-S1 loads within the limits (e.g., 3400 N for compression recommended by NIOSH and 1000 N for shear recommended in some studies). Fifty lifting activities are simulated here to evaluate the RWL by the NLE and the L5-S1 loads by the predictive equations. In lifting activities involving...
The Application of a Classification-Tree Model for Predicting Low Back Pain Prevalence Among Hospital Staff
Low back pain (LBP) is a widespread musculoskeletal condition that frequently occurs in the working-age population (including hospital staff). This study proposes a classification-tree model to predict LBP risk levels in Sacré-Cœur Hospital, Lebanon (as a case study—236 chosen staffs) using various predictor individual and occupational factors. The developed tree model explained 80% of variance in LBP risk levels using standing hours/day (90% in relative importance), job status/sitting hours per day (80% each), body mass index (71%), working days/week (63%), domestic activity...
Intervenir sur les TMS. Un modèle des Troubles Musculo-squelettiques comme objet intermédiaire entre ergonomes et acteurs de l’entreprise ?
Buchmann, W. & Landry, A. (2010). Intervenir sur les TMS. Un modèle des Troubles Musculo-squelettiques comme objet intermédiaire entre ergonomes et acteurs de l'entreprise, Activités 7(2), pp. 84-103, http://www.activites.org/v7n2/v7n2.pdf. Une étude de cas multiples menée sur plusieurs interventions visant la prévention des Troubles Musculo-squelettiques (TMS) nous a permis de tester les qualités opératives de l'utilisation par les ergonomes d'un modèle de TMS pour favoriser la prévention durable dans les entreprises...
