A participatory approach could be used to implement work place or organizational improvements. However, the question is which participants should be involved and how. In this paper the theoretical involvement in different steps of a linear stepwise approach is described and compared with the latest projects of 300 practitioners. From a theoretical point of(More)
The influence of an artificial leg length discrepancy (= ALLD) on stride times, pelvic rotations and activity of the intrinsic lumbar back muscles (= ILBM) was investigated for 20 subjects. An ALLD was created by shoes with a raised sole. Walking with an ALLD produced an increase of the swing phase time and a decrease of the stance phase time for both feet.(More)
In the last few years context awareness has emerged as an important element in distributed computing. It offers mechanisms that allow applications to be aware of their environment and enable these applications to adjust their behavior to the current context. Considering the dynamic nature of context, the data flow of relevant contextual information can be(More)
A simple model of the thorax, pelvis and three columns of the intrinsic lumbar back muscles (= ILBM) was constructed. The model was used to study the length of the ILBM during the different stages of the walking cycle. The length of the right ILBM (especially the lateral column) was largest at right toe off, exactly the stage of the walking cycle in which(More)
Lifting, carrying, pushing and pulling at work are assumed to be related to increased risks of musculoskeletal injury, mainly in the low back and shoulder region. The implementation of products to reduce the physical load in heavy work is a well-known strategy to attack this problem. The success of these products depends not only on the product itself, but(More)
The aim of this paper was to provide recommendations for ergonomists involved in project design and evaluation. Twelve research and consultancy projects involving ergonomics interventions in a variety of settings in The Netherlands were analysed to identify factors important to success. Projects included participatory and non-participatory cases. Eight(More)
Context awareness has emerged as an important element in distributed computing. It offers mechanisms allowing applications to be aware of their environment and enabling them to adjust their behavior to the current context. In order to keep track of the relevant context information, a flexible service mechanism should be available for the client(More)
Participatory ergonomics is reported in an increasing number of case studies, but there is little evidence of emerging supportive theory and relatively little generic advice or guidance. The paper describes an effort to provide clarity and organization to the field of participatory ergonomics. A framework has been developed to define a range of different(More)
This review aimed at producing insight into the effectiveness of interventions to reduce the physical work demands associated with manual (materials) handling in the work situation and musculoskeletal symptoms in the longer-term. A systematic electronic literature search between 1990 and February 2003 was performed in the following databases: Embase,(More)
In a Department of Salary Records where VDU tasks were performed at a high work rate, a participative ergonomic study was undertaken. First, the 'old' workplace was investigated for all 45 employees. Work stations appeared to be of poor ergonomic quality. Second, 12 employees participated in an experiment at the actual workplace. Objective and subjective(More)
