Outline of Research at the Start |
脳卒中片麻痺患者は,高齢者と比較して歩行中の転倒が多いことが報告されている.転倒予防に向けた歩行中の転倒予測は重要な課題である.従来,歩行中の転倒予測には,歩行速度や歩幅などの歩行指標が用いられてきたが,脳卒中片麻痺患者は歩行の非対称性や非定常性といった疾患特有な歩行障害を呈すため,従来の歩行指標からの転倒予測は不十分であり,「歩容(歩き方)」に着目する必要性が指摘されている.しかし,脳卒中片麻痺患者の歩容と転倒との関連は明らかにされていない.本研究の目的は脳卒中片麻痺患者の歩容と転倒の関連性を明らかにすることで,歩行評価に基づく転倒予測システムの構築へと発展させることである.

Outline of Final Research Achievements |
Falls in stroke patients occur most frequently while walking. Decreased walking ability is a risk factor for falls. Prediction of falls based on gait assessment is important to prevent falls in stroke patients. Therefore, we considered the prediction of falls based on "kinematic gait asymmetry" using joint angles during gait. The gait index we developed can capture gait in more detail and comprehensively. This study revealed that (1) stroke patients show significant kinematic gait asymmetry in the hip, knee, and ankle joints compared to healthy adults, (2) kinematic gait asymmetry in the hip and knee joints is associated with walking speed, balance, and daily living activities, and (3) kinematic gait asymmetry in the hip and knee joints is associated with fear of falling.

Academic Significance and Societal Importance of the Research Achievements |
本研究の結果は,脳卒中患者のリハビリテーション場面で主観的に評価されていた歩容を定量化したことで今後のデータ蓄積に貢献できると考える.今回示した運動学的歩行非対称性が臨床指標と関連したことから,歩行能力や日常生活活動を改善するための歩行リハビリテーション戦略の一助になりえる.また,運動学的歩行非対称性が転倒との直接的な関連はないものの転倒恐怖感と関連したことは,歩行評価に基づく転倒予測システム構築に向けて貴重なデータとなったと考える.
