Evaluation of Motion Adaptability of Jackets : By Using Sensory Test/Motion Time/EMG

Focusing on the stretch factors of the materials, the motion adaptability of jackets was evaluated to design comfortable clothing. A total of ten subjects, five healthy younger females and five elder females who resided alone in senior citizen houses, participated in the study. For movement to wear and to remove a jacket and 7 types of movement of the upper limbs were measured. In the sensory test was evaluated using a five-rank system. In the EMG, the deltoid muscles were measured by the surface electrode method. The movements were recorded with the digital video. The result of the sensory test for the material of the jacket was significant at 1% or 5% level in both the younger and elderly groups. In this test for evaluating the ease with which the jackets were worn and removed, those with higher stretch factors were highly ranked. There was a difference of time to wear and to remove the jacket by the material. These jackets were compared by using the integral values obtained for muscle activities pertaining to each movement of the upper limbs. The result revealed the integral values changed in two patterns depending on the stretch of the material.11KJ00004724519論文Articledepartmental bulletin pape
