| Abstract |
パーキンソン病患者 (PD)、健常高齢者、健常若年者を対象にLaser計測システムを用いてTimed up and go test (TUG) を評価した際の、足接地位置、下肢移動軌跡、歩行の時空間指標について検証し、PD患者は方向転換の際、視覚指標の近くに足を接地し、その足接地パターンが方向転換時の歩幅の低下と関連することを解明した。
新たに、画像と深度情報を同時に取得可能なRGB-Dセンサを複数台用いた非接触型3次元動作計測システムを構築し、歩行動作時の計測値の妥当性を実験的に検証した。また、変形性膝関節症の高齢者の動作計測実験に適用し、有用性を確認した。
We evaluated the timed up and go test (TUG) using the Laser measurement system in patients with Parkinson's disease (PD), healthy elderly subjects (HO), and healthy young subject (HY) and investigated the characteristics of foot contact positions, leg trajectories and spatiotemporal gait parameters.
As a result, it was confirmed that the minimum distance from the turning point to foot contact position and the turning-phase step length in the PD group are significantly smaller versus those of the HO group, and the two parameters were significantly positively correlated.
We constructed a novel non-contact type 3D motion measurement system using multiple RGB-D sensors that can simultaneously acquire images and depth information, and experimentally verified the validity of the measured gait parameters. The effectiveness of the proposed system was confirmed by applying it to the motion measurement experiment of the elderly with knee osteoarthritis.
