A study within the Danish National Birth Cohort Objectives : Pelvic pain during pregnancy is a common ailment, and the disease is a major cause of sickness absence during pregnancy. It is plausible that occupational lifting may be a risk factor of pelvic pain during pregnancy, but no previous studies have examined this specific exposure. The aim of this study was to examine the association between occupational lifting and pelvic pain during pregnancy. Methods : The study comprised 50 143 pregnant women, enrolled in the Danish National Birth Cohort in the period from 1996–2002. During pregnancy...
Objective: The aim of this study was to evaluate long-term efficacy of an ergonomics program that included patient-handling devices in six long-term care facilities (LTC) and one chronic care hospital (CCH). Background: Patient handling is recognized as a major source of musculoskeletal disorders (MSDs) among nursing personnel, and several studies have demonstrated effectiveness of patient-handling devices in reducing those MSDs. However, most studies have been conducted in a single facility, for a short period, and/or without a comprehensive ergonomics program. Method: Patient-handling devices...
Objectives: Mechanical load during patient handling activities is an important risk factor for low back pain among nursing personnel. The aims of this study were to describe required and actual use of ergonomic devices during patient handling activities and to assess the influence of these ergonomic devices on mechanical load during patient handling activities. Methods: For each patient, based on national guidelines, it was recorded which specific ergonomic devices were required during distinct patient handling activities, defined by transferring a patient, providing personal care, repositioning...
Objective: Using an observational research design and robust surveillance data, we evaluated rates of musculoskeletal (MS) injuries, days away from work, and restricted work days among patient care staff at a medical center and community hospital in the United States over 13 years, during which time a “minimal manual lift” policy and mechanical lift equipment were implemented. Methods: Workers’ compensation claims data were linked to human resources data to define outcomes of interest and person-time at risk to calculate rates. Poisson and negative binomial regression with lagging...
OBJECTIVES: Epidemiologic studies on physical exposure during computer use have mainly focused on average exposure duration. In this study, we aimed to relate periods of high peak exposure during computer use with the occurrence of neck-shoulder (NS) and arm-wrist-hand (AWH) symptoms. METHODS: A prospective cohort study among 1951 office workers was carried out for two years, with periodical questionnaires and continuous measurements of computer input use. To define peak exposure, a distinction was made between peak days and weeks. Peak days were defined as days with a long duration of computer...
An epidemiological prospective cohort study of the ability of the 1991 NIOSH Lifting Equation to predict loss of time from work due to low back pain (LBP) or to predict reports of LBP followed 515 industrial workers in jobs requiring manual handling for 18 months. Baseline measurements were made of their jobs, histories of musculoskeletal trouble and of psychosocial variables. Longitudinal analysis of tasks was based on 367 subject/job combinations. The strongest predictor of future LBP was a history of LBP. No relationship was found between the Composite Lifting Index (CLI) and either the incidence...
In 2009, the operating height of approximately one fourth of underground coal mines in the U.S. restricted mine workers to kneeling, crawling, and/or stooping posture to perform work [MSHA 2009). The large number of knee injuries to these workers is likely attributed to exposure to musculoskeletal disorder risk factors (prolonged kneeling, crawling, and twisting on one's knees). Therefore, the National Institute for Occupational Safety and Health has investigated three different biomechanical parameters (muscle activity of the knee flexors and extensors, pressure at the knee, and the net forces...
Une étude sur la charge de travail et la dépense énergétique des éducateurs physiques vient d'être publiée par l'IRSST. Elle démontre qu'en général la dépense énergétique des éducateurs physiques varie de faible à moyenne lorsqu'exprimée en valeur absolue. L'objectif principal de l'étude visait donc à quantifier la dépense énergétique de la tâche de l'éducateur physique dans son milieu de travail, en fonction de...
Des solutions pour mieux intervenir dans les milieux de travail Quelque 150 personnes ont participé à cet événement qui a permis de faire le point sur l'état de la recherche en matière de manutention manuelle. Les présentations PowerPoint des conférenciers sont disponibles sur le site de l'IRSST. Source : http://www.irsst.qc.ca/conference-manutention2010.html
Le succès mitigé des programmes de formation sur la prévention des blessures au dos en manutention s'explique peut-être par la faiblesse de nos connaissances pratiques sur ce que font les experts dans la réalisation de leur travail. Des études ont montré que des manutentionnaires d'expérience, reconnus par leurs collègues comme étant des experts, ont développé des façons de faire différentes des novices qui pourraient être à la fois sécuritaires et avantageuses en termes...
The purpose of this report is to investigate the manual handling and work related risk factors for MSD associated with the installation of plasterboard, and to evaluate the impact of manual handling aids in terms of risk reduction and the time taken to install plasterboard.

Adams, KJ, DeBeliso, M, Sevene-Adams, PG, Berning, JM, Miller, T, and Tollerud, DJ. Physiological and psychophysical comparison between a lifting task with identical weight but different coupling factors. J Strength Cond Res 24(2): 307-312, 2010-The objective of the revised NIOSH (National Institute for Occupational Safety and Health) lifting equation is to prevent or reduce lifting-related injuries. The coupling component of the equation relates to quality of the grip (i.e., hand-to-object interface) and can be rated good, fair, or poor. Good coupling is theorized to reduce lifting stress, whereas...
Working in an Uncontrolled Environment You hope the discharge planner was a good one. You hope the doors aren't too narrow for the wheelchair and the bed is higher than knee-level. Even then, as likely as not, your work area will be the size of a crawlspace and strewn with clutter and medical equipment. Welcome to life as a home healthcare provider. In 2007, America's 896,800 home healthcare workers reported a staggering 27,400 injuries. Some of these resulted from unintentional needlesticks, latex allergies, and violence against providers. However, the most common injuries were sprains...
A new downloadable tool is now available to help businesses and organisations reduce the likelihood of their employees suffering from musculoskeletal disorders (MSDs) of the upper limbs associated with repetitive tasks. MSDs are the most common occupational illness in Britain affecting more than 500,000 people every year and are often linked to repetitive work tasks such as packing on a production line or the regular use of hand tools. The Assessment of Repetitive Tasks (ART) tool, developed by the Health and Safety Executive (HSE) and Health and Safety Laboratory (HSL), can help identify where...
A systematic review Injuries caused by manual handling are a major burden to society. Manual handling training programmes have been designed to reduce the likelihood of injury among the workforce; however, concerns have been raised over the efficacy of current manual handling training methods.
