- Postural Stability Assessment during Manual Material Handling Tasks – Case StudyPublication . Azevedo, Rui; Martins, Cristina; Sá, Maria Manuel; Teixeira, José; Barroso, MónicaHuman body is a system of segments connected by joints; any voluntary motion of the body causes internal perturbation of balance. Manual handling of loads such as load lifting may increase these perturbations. In a bi-manual whole body lifting task, the grasp of a load and pick it up from the floor induces a forward shift in the position of the centre mass, challenging the dynamic balance regulation while simultaneously impending the ongoing extension movement. In order to compare the disturbance of balance both in back lifting or leg lifting of a frontal load a laboratory-based case-study was performed through the simulation of lifting tasks. A twenty-eight male worker frontally lifted a box from the floor. Two experimental conditions were applied: the participant used leg lift (straight back, bent legs) or back lift (straight legs, bent back) with combinations of two different weight materials. Through the application of the Index of Proximity to the Stability Boundary it was found that both techniques adopted for load lifting seem to equally influence postural balance control. In addition, it was concluded that manual lifting of heavier loads may jeopardize postural balance increasing the occurrence of falls.
- Psychophysical study of manual loads transportation - a comparative study between students and seasoned workersPublication . Oliveira, Elsa; Rodrigues, Matilde; Silva, Manuela; Azevedo, Rui; Carvalho, AlbertoThe psychophysical criteria are important to develop manual material handling guidelines. It is essential that the studies that use a psychophysical approach be carried out as accurately as possible. However, the sample used in these studies can influence the results, if not appropriate. This work intends to analyze the influence of the sample in determining the maximum acceptable weight (MAW) in tasks of manual transport of loads transportation. The study involved 10 students and 10 workers. The participants’ task was to carry a box for 13 minutes and travel six meters. The box had the dimensions of 60 cm length × 40 cm width x 40 cm deep and the handles had 2.7 cm width and 9.0 cm in length. Moreover, subjects were required to carry out the movement of the box with the trunk erect and the forearms perpendicular to the body. In the end, the MAW and the rate of perceived exertion (RPE) were determined. A strength test was applied to each individual. The MAW was higher for students (11.6kg) than for workers (10.8kg), however, it was not verified significant differences between groups. For students, the MAW depended on the selected IW. Students also assigned RPE values higher than workers. These results suggest that the workers' experience may be a determining factor in the MAW. Although the study has not provided conclusive results, it can be argued that samples comprised by students may affect the results, being that these groups of samples should be used with caution. So, whenever possible it should be used experienced workers in real work context for psychophysical studies.
