Validation of the HSE manual handling assessment charts as predictors of work-related low back pain
The aim of this research was to ascertain whether HSE's ‘Manual handling Assessment Charts' (MAC tool) could be used to predict workers losing time from work due to low back pain (LBP). Results from the study suggest that as the ‘Hand distance from the lower back' increased, the risk of lost time due to LBP increased. For each 10 cm increase, the rate of lost time increased by approximately 20%. No evidence of relationships between other risk factors in the MAC and lost time was found. There was no evidence that the rate of lost time due to LBP increased with either increasing...
Practical Demonstrations of Ergonomic Principles
Musculoskeletal disorders (MSDs) often involve the back, wrist, elbow, and/or shoulder, and occur when workers are exposed over time to MSD risk factors, such as awkward postures, forceful exertions, or repetitive motions. These exposures sometimes occur due to poorly designed workstations, tasks, and/or hand tools [Chaffin et al. 2006; Sanders and McCormick 1993; Silverstein et al. 1996, 1997]. Workers must understand the nature of MSD risk factors and how to avoid exposure to them. In a classroom setting, trainers may discuss ergonomic principles and show examples of MSD risk factors with photographs...
