Abstract
Frequently users of wheelchairs are subject to vibrations due to soil irregularities. In many cases these vibrations can reach high levels and lead to damage to health of these users. Thus the goal of this work is to evaluate the exposure of wheelchair users to vibrations, who are continuously under these vibrations in their routine. This work was performed through vibration measurements carried out in two wheelchairs, one manual and the other motorized. The evaluations were performed according to the ISO-2631, where the limits of vibration levels and maximum exposure times were analyzed. The worst case was related to the stone pavement and motorized chair with a maximum exposure time of one hour and a half. 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.
