Abstract

ベッドから車椅子までの移乗介護動作を,3次元動作解析装置と床反力による測定により,局面化を分析した。右片麻痺の模擬利用者に対する移乗介護動作の映像データ及び介護者の重心に近い左右の上後腸骨棘の中点の移動軌跡と床反力の大きさと角度から,局面化を検証した。まず,位置,速度,加速度の各データからグラフ波形の極値を捉え,(1)開始期,(2)引き付け期,(3)立ち上がり期,(4)回旋期,(5)着座期,(6)座位期の6つに局面化した。この妥当性を,介護者の左右の上後腸骨棘の中点の移動軌跡,速度,加速度ならびに床反力から検証した。左右上後腸骨棘中点では3次元グラフ化した移動軌跡の方向転換点である極値,左右上後腸骨棘中点の移動の速度と加速度の極値,床反力では,力の大きさと方向性の極値からそれぞれの局面化の最大の同期性を検証した結果,6つの局面化において同期していることから,その妥当性が3次元動作解析で検証できた。

The process of wheelchair transfer assistance from a bed to a wheelchair was examined, and the division of the process into phases was examined by using a three-dimensional biomechanical analysis device and floor reaction force plate. Models that portrayed right hemiplegic patients were used in the simulation of the performance of wheelchair transfer assistance. The movements were tracked at the center point between the right and left posterior superior iliac spines, which is approximately the center of gravity of a human body. The floor reaction force, speed, and acceleration were measured. First, the extreme values in the graph were calculated from position data, speed data, and acceleration data. The movements were divided into the following phases: (1) beginning, (2) shifting, (3) standing up, (4) turning, (5) sitting down, and (6) adjusting seating position. After verifying the tracks of the movement, the verification of the phases of the wheelchair transfer assistance performance was obtained from the floor reaction force combined with the movement tracks, speed, and acceleration. After the tracks of the movement were graphed in three dimensions, the turning points of the tracks were found to be almost synchronous with changes in the floor reaction force, speed and acceleration, resulting in the validity for dividing the wheelchair transfer assistance performance into six phases.
