生活行為における力学環境の評価手法の提案 : 車椅子による段差越えを例として  [in Japanese] A PROPOSAL ON THE EVALUATING METHOD FOR MECHANICAL ENVIRONMENT IN DAILY ACTIVITIES : A case of barrier with wheelchair  [in Japanese]

The purpose of this study was to establish the appropriate guidelines on homes with barriers such as steps and stairs. For this, an evaluating method of mechanical environment was proposed: a combined method of measurement of acceleration obtained by the small triaxial accelerometers attached on a human body and the perceptual test (Semantic Differential Method) with five pairs of adjectives. In order to verify the effectiveness of this method, two different kinds of wheelchairs were employed in this study; 1) one with a caster to absorb the shock from bumping against the barriers 2) one without it. The findings are: 1) As the barrier became higher and the wheelchair speeded up, the acceleration was increased and the scores of the perceptual test were rated low. 2) The caster with a bumper successfully reduced the shock. 3) Measurement with the accelerometer was considered to be effective for the evaluation of mechanical environment in daily activities, although this research restricted only to barriers.
