Work-related Musculoskeletal Disorders, a tri-sector exploration
High rates of WRMSD-related sick leave put pressure on employers and businesses, hitting their bottom lines and potentially leading to understaffing, reduced productivity and lower staff morale. Directly affected workers not only suffer pain but also consequences that can be felt across their working, home and social lives. The construction, healthcare and transportation and storage industries were selected as the focus of this research because they have significantly higher rates of WRMSDs compared with the average rate for all industry. Qualitative research was commissioned to: - Explore what...
Occupational biomechanical risk factors for surgically treated ulnar nerve entrapment in a prospective study of male construction workers
Evidence was provided for forceful hand-grip work, with and without vibration, as a risk factor for ulnar nerve entrapment (UNE) surgery in a large cohort of Swedish construction workers. Several individual biomechanical factors comprising such work were associated with increased risk of UNE, including: increased grip force, upper extremity load, frequency of hand-held tool use, and hand arm vibration.

La prévalence des troubles musculosquelettiques (TMS) et les liens avec les contraintes de travail dans une population d'électriciens ont été étudiés par le questionnaire TMS de l'INRS, les échelles de Borg, des mesures de vibrations et des études de poste ergonomiques. Les principaux TMS concernaient le rachis, notamment lombaire, et le poignet droit, en lien avec une exposition intense à des contraintes posturales. Les TMS du poignet et de l'épaule étaient également liés à l'exposition...
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...
Associations of objectively measured sitting and standing with low-back pain intensity
A 6-month follow-up of construction and healthcare workers This study investigated associations between sitting and standing, respectively, and low-back pain with objectively measured exposures for several days and a prospective design. Sitting at work and during full-day is negatively associated with cross-sectional- and prospective low-back pain intensity. This association was seen for the healthcare sector, but not for the construction sector. Source: Lunde, L. K., Koch, M., Knardahl, S., & Veiersted, K. B. (2017).

Workers' compensation claims for musculoskeletal disorders and injuries of the upper extremity and knee among union carpenters in Washington State, 1989-2008
BACKGROUND: Numerous aspects of construction place workers at risk of musculoskeletal disorders and injuries (MSDIs). Work organization and the nature of MSDIs create surveillance challenges. METHODS: By linking union records with workers' compensation claims, we examined 20-year patterns of MSDIs involving the upper extremity (UE) and the knee among a large carpenter cohort. RESULTS: MSDIs were common and accounted for a disproportionate share of paid lost work time (PLT) claims; UE MSDIs were three times more common than those of the knee. Rates declined markedly over time and were most pronounced...
Ergonomic design of crane cabin interior
The path to improved safety Many procedures in the development process of crane cabins today are still based on the specific experience of manufacturers and historical guidelines. It is not surprising that they fail to meet the needs of a large proportion of operators. Accordingly, the need for more objective, theoretically justified and consistent models, that will minimize crane operators' biomechanical and visual problems through anthropometric characteristic analysis to improve safety and prevent crane related fatalities and injuries, arises. In that aim we firstly identified the critical...

Are elderly construction workers sufficiently fit for heavy manual labour?
This study analysed the work ability of elderly construction workers. Forty male construction workers, 20 young (age < 33 yrs) and 20 senior (age>44 yrs) workers, were tested regarding aerobic power (VO2max) and muscle strength. The aerobic demand of a number of tasks in construction work was measured and compared with the workers' aerobic power. VO2max was higher for the young, and they performed better on most muscle strength tests. The measurements showed that about half of the senior workers had to use more than 30% of their maximum oxygen uptake on some tasks. In conclusion, because...
Shoulder muscle loading and task performance for overhead work on ladders versus mobile elevated work platforms
A high incidence of Musculoskeletal Disorders (MSDs) has been reported in the construction sector. The use of ladders in the workplace has long been identified as a significant risk that can lead to workplace accidents. However, it is unclear if platform types have an effect on the physical risk factors for MSDs in overhead work. The aim of this study is to perform a pilot study on the effects of hand activity on both shoulder muscle loading and task performance while working on ladders versus Mobile Elevated Working Platforms (MEWPs). It is hypothesised that work on ladders would result in greater...
Declining rates of work-related overexertion back injuries among union drywall installers in Washington State, 1989-2008
Improved work safety or shifting of care? INTRODUCTION: Construction workers are at high risk of work-related musculoskeletal back disorders, and research suggests medical care and costs associated with these conditions may be covered by sources other than workers' compensation (WC). Little is known about the back injury experience and care seeking behavior among drywall installers, a high-risk workgroup regularly exposed to repetitive activities, awkward postures, and handling heavy building materials. METHODS: Among a cohort of 24,830 Washington State union carpenters (1989-2008), including...
Efficient assessment of exposure to manual lifting using company data
"The objective of this study, based on an extensive dataset on manual materials handling during scaffolding, was to explore whether routinely collected company data can be used to estimate exposure to manual lifting. The number of manual lifts of scaffold parts while constructing/dismantling scaffolds was well predicted by the number of scaffolders in the team and the type of worksite, in combination with company data of either the number of scaffold parts or the scaffold volume. The proportion of explained variance in the number of lifts ranged from 77% to 92%, depending on the variables...

An Intervention for Overhead Drilling into Concrete
One of the most physically demanding tasks associated with musculoskeletal injuries (MSIs) in the construction industry is overhead work, particularly drilling into concrete ceilings in order to hang pipes, ducts, conduit, and wiring trays. This research project refined and tested an intervention device called an Inverted Drill Press (IDP) that is designed to reduce the shoulder force, awkward neck postures, dust exposure and risk of falling associated with overhead drilling. The IDP supports a hammer drill at the top of a ground-supported column that can be raised to the drilling site so the user...
Reducing Work-Related Musculoskeletal Disorders among Rodbusters
NIOSH evaluated reinforcing ironworkers' (rodbusters) exposures to risk factors for developing low-back and hand disorders when tying together reinforcing steel bars (rebar) on a freeway bridge. Rodbusters used three techniques to tie rebar together—a pliers and a tie wire wheel, a battery operated power tier (PT), and a PT with an extension handle (PTE). NIOSH found that using the PT and PTE reduced the rodbusters' exposures to risk factors for work-related low-back and hand-wrist disorders. In addition, power tying was twice as fast as than pliers tying. Source : http://www.cdc...

Study tests ways to increase uptake of ergonomic innovations
Ergonomic innovations in the construction sector could potentially reduce soft-tissue injuries or musculoskeletal disorders (MSDs), which represent 35 per cent of the sector's injuries in Ontario. However, introducing change is difficult because of the ever-changing nature of construction work. This study aimed to find out if “opinion leaders” — influential people from companies identified as respected trend-setters — might be a good way to promote new health and safety ideas within this complex sector. http://www.iwh.on.ca/highlights/study-tests-ways-to-increase-uptake...
Ergonomics case study: Car parts manufacturer realizes benefits of PE program
An Ontario manufacturer opened its doors to researchers who helped implement a participatory ergonomics (PE) program to improve the musculoskeletal health of workers. The company has since learned that the PE program saved it almost a quarter-of-a-million dollars — and in the most unexpected place. http://www.iwh.on.ca/at-work/57/pe-case-study
