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.

Évaluation de la prévalence des plaintes de troubles musculosquelettiques et du lien avec les contraintes de travail chez des électriciens du BTP
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...
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...
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...
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 investigation into the use of plasterboard manual handling aids in construction
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.
