健康な大学生の男女 48 名を対象に,速度計・加速度計・体圧分布測定器を装着したス トレッチャーを用いて,અkm/時,ઇkm/時,ઉkm/時と速度を変えて定められた経路 に従って移送を行い,方向転換時における乗車者にかかる加速度と頭部の重心移動の大 きさを測定した.その結果,ストレッチャー移送の方向転換時においては,速さが速く なるにつれ,前後・左右方向ともに加速度が大きくなり,それに伴い頭部の重心移動距 離も大きくなった.さらに,すべての速度の加速度と頭部の重心移動距離は,左右・前 後方向ともに,正の相関関係が認められた.速度の上昇に伴い,頭部が大きく振られる ことから,頭部外傷や頸椎損傷の患者の容態に悪影響を及ぼす可能性があることを念頭 において移送する必要があるとの示唆を得た. キーワード:ストレッチャー,重心移動,速度の違い,方向転換 With 48 healthy university students, male and female, as subjects, using a stretcher to which a velocimeter, accelerometer

The results were that during course changes in stretcher transportation, when the velocity was high, the acceleration was also high, in both forward-backward and left-right directions, and accompanying that, the distance of the shift in the center of gravity was also large. Additionally, a positive correlation was observed in acceleration and distance of the shift in the center of gravity at all velocities, in both forward-backward and left-right directions. Accompanying an increase in velocity, from the fact that the head undergoes significant movement, it is indicated that there is a necessity, while transporting, of keeping in mind the possibility that the condition of patients with head trauma or cervical spine injury may be negatively affected.
