Avaliação da exposição de cadeirantes às vibrações mecânicas: um estudo comparativo de cadeiras manuais e motorizadas em pavimentos públicos

Abstract

The objective of the study is to evaluate the exposure of whole body vibration in wheelchair users, who are continuously under these effects in their routine. This study is carried out by means of vibration measurements carried out in two wheelchairs, one manual and one motorized. Based on the routine of wheelchairs in large cities, the predominance in three public floors, asphalt, stone pavement and paver pavement is evaluated. The evaluations were performed according to ISO-2631, where the limits of vibration levels and maximum exposure times were analyzed. The worst case was related to stone paving and motorized wheelchair with a maximum exposure time of one hour and thirty minutes. This work presents a scientific and social approach, since the experiments developed and their results can be used by wheelchair manufacturers, which can lead to improvements in wheelchair transportation.
