A manual handling task (an order picking task in a distribution warehouse) was investigated using concurrent verbal protocols and retrospective verbal protocols (applied at three different times after completion of the task). The study aimed to collect workers' thoughts during the task and to determine what workers are comfortable with reporting. Video(More)
The present study was conducted to review the literature on the methods that have been considered appropriate for evaluation of the effects of gloves on different aspects of hand performance, to make recommendations for the testing and assessment of gloves, and to identify where further research is needed to improve the evaluation protocols. Eighty-five(More)
An experiment was carried out to investigate the effects of handle design on postures in the use of pots. Six combinations of handle (sloping, vertical and curved) and spout designs (long and short) were tested during grasping, lifting and pouring. The fill load was 1000 ml of water at the prevailing room temperature (about 20 degrees C) and three males and(More)
Concurrent and retrospective verbal protocol methods were used to collect thoughts from 18 participants during a manual handling task involving the repeated transfer of loads between locations at two tables. The effectiveness of qualitative and quantitative methods of analysing the reported information was tested in the study. A simple taxonomy was(More)
Sewing machinists suffer from musculoskeletal problems, which have been attributed to poor working postures as well as to the repetitive hand and arm movements. Their posture is constrained by both the visual and the manual aspects of the task, and the design of the sewing machine and table have a considerable influence on the posture adopted. The potential(More)
An awkward and static work posture has been recognized as a risk factor for work-related musculoskeletal problems. The objective of this study was to investigate some of the factors that can influence the posture adopted during work and in particular aspects of the task and how their influence is affected by work height. Three types of task were studied: a(More)
No clear definition of 'posture' can be found in ergonomics literature. It may be regarded as the configuration of the body's head, trunk and limbs in space or as a 'quasistatic biomechanical alignment' (Rohmert and Mainzer 1986), depending on whether the particular context in which it is used is anatomical or biomechanical. The functional aspects of(More)
Isometric strength data have been collected for three of the awkward work situations often imposed by workplace constraints in industry, as found in jobs such as maintenance and repair. The effects of the task layout factors (location of the workpiece, reach distance and direction of force exertion) were investigated and the data has been tabulated to show(More)
Manual transport aids (trucks and trolleys) are in widespread use throughout most industries, but their use does not always result in the anticipated reduction of workload or musculoskeletal stress. A survey of users has shown that many of the aids currently used are poorly designed or inappropriate for the tasks performed. The information gained during the(More)
