歩行時の肩荷重計測と動作解析によるショルダーバッグの機能評価

抄録

The aim of this study is to evaluate the performance of a shoulder bag with a function that fits the body during walking. The load applied to the shoulder was measured using a small triaxial force sensor, the walking motion of the body and the shaking of the bag were evaluated using a motion analysis device. 12 participants walked for about 2 minutes on the treadmill. Two types of bags named “FIXTOTE” with different sizes（M and S）were used in this study. Each of the two types of bags has two conditions（without strap（without condition）and use strap（with condition））. The force of load on shoulder, the shake of bag and the step length were measured. It was clarified that the combined force of the load on the shoulder decreased, the shake of the bag was suppressed when the strap was used rather than not used. The step length has no significant difference whether the strap used or not. This study revealed the dispersion effect of load on shoulder, the suppression effect of bag shaking during walking and the influence on walking motion.
