Manual handling is recognised as a major cause of work-related back injuries. Although widely implemented, manual handling training programmes appear to have had limited success in reducing these injuries. This may stem from the inadequacy of training programmes and/or their inability to accommodate variations in task, workplace, and worker. Designing training programmes based on the techniques...

The purpose of this study was to measure dose of spinal load when different pacing methods were applied to lifting work and to develop methodology for such measurements. The compressive load on the spine computed by a dynamic biomechanical model and the electromyographic activity of back muscles were used for describing the spinal load. Five men and five women worked in a laboratory on two days...

The main purpose of this article is the structural analysis of a composite blade of a selected helicopter. In this study, the stresses on rotors' blades caused by centrifugal forces, lift, drag and torque are analyzed. The governing equations of the structure behavior and solving processes were carried out by MATLAB software, and simulation is carried out by ABAQUS software, and they are compar...

This study recruited 14 young male participants to examine human 4-h maximum acceptable weight of lifting (MAWL) and maximum weight of lifting (MWL) for different modes of asymmetric lifting and containers. The results showed that asymmetric lifting with trunk rotation decreased MAWL and MWL by 9.1 and 17.3%, respectively, and asymmetric lifting with body turn decreased MAWL and MWL by 6.1%, wh...

The action abilities of an individual observer modulate his or her perception of spatial properties of the environment and of objects. The present study investigated how joint action abilities shape perception. Four experiments examined how the intention to lift an object with another individual affects perceived weight. In Experiments 1, 2a, and 2b, participants judged the perceived weight of ...

Vincent Palmieri : Development of Test Methods for Evaluation of Wheelchair Cushions. That article and a related paper on details of test equipment employed appear in this issue of The Bulletin of Pros-thetics Research. This issue of the Bulletin reports some very commendable efforts to measure the pressure and shear stresses that impinge on human flesh as a result of sitting in a wheelchair on...
