Wheelchair users are exposed to whole-body vibrations on daily activities especially while running on the various road surfaces: the boundary curb between pavement and roadway, bumps, uneven terrain, damaged asphalt or concrete surfaces. Some extended exposure to such vibrations may cause discomfort and physiologic trauma such as chronic low back pain and neck pain, muscle ache and fatigue, hemiated discs, degradation of vertebrae. This research aims the quantitative evaluation of the wheelchair user's whole-body vibrations running on the various road conditions. And the goal of this study is to improve the mechanism of wheelchairs and to propose preferable road conditions of an easy-to-use for all by the universal design. The whole-body vibration were measured at the seat of wheelchair as the same methods as the ISO 2631-1. The results of Root Mean Squared (RMS) acceleration of whole-body vibration showed the similarity of characteristics between persons and dummy and the possibility to assume the influences of road surfaces by dummy instead of human body, and also, the risk for some injuries due to vibrations while running various road surfaces.
