パーキンソン病の定量的診断支援を目指し,歩行時の圧分布よりパーキンソン病患者と健常者を識別可能な特徴量を抽出した.圧分布の計測には,シート型圧力センサを用いた.歩幅,ステップ時間,歩行速度,足軸方向の荷重中心変化を特徴量とした.パーキンソン病患者6名と健常者14名で歩行実験を行った.歩幅,歩行速度は健常者と比べてパーキンソン病患者が小さかった.ステップ時間は健常者より長いパーキンソン病患者もいるが,健常者と変わらないパーキンソン病患者もいた.足軸方向の荷重中心変化は歩幅の小さい被験者が小さかった.これらの特徴量により,パーキンソン病患者と健常者の識別可能性があることを示した. |

We extracted features of gait from the pressure distribution measured by using sheet-shaped pressure sensor in order to diagnoses quantitatively Parkinson's disease. Features were calculated step length, step time, gait velocity and transition of center of force to foot axis direction. We conducted gait experiments with 6 Parkinson’s disease subjects and elderly 14 normal subjects. The step length and gait velocities calculated in Parkinson’s disease subjects were lower than normal subjects. The step times calculated in 3 Parkinson’s disease subjects were longer than normal subjects, but the step times calculated in other Parkinson’s disease subjects were as long as normal subjects. The transitions of center of force to foot axis direction in the subjects whose step length were small were low. It was shown that it was possible to make a differentiation between Parkinson’s disease subjects and normal subjects by these features. |
