Abstract
Purpose: The aim of the study was to quantitatively evaluate the vibrations received on the wheelchair footrest and to determine whether wheelchair users are at risk of vibration-white foot. This assessment was made using the ISO 2631 standard.
Methods: The measurements were taken on the footrest of a universal wheelchair. The tests were carried out on five surfaces frequently found in public spaces and measurements were carried out on a study group of eight non-disabled people.
Results: The vibration values received on the footrest of a universal wheelchair are higher compared to the vibrations received on the seat. It was found that the comfort limit defined by the ISO 2631 standard for frequencies in the range of 30–40 Hz was exceeded.
Conclusions: Research shows that a wheelchair user is exposed to whole body vibrations occurring on the footrest. It therefore seems reasonable to take steps to minimize this factor.
