Outline of Final Research Achievements

This study examined the feasbility, reliability, construct validity, concurrent validity, and predictive validity of a novel motor-cognitive dual-task test, the Stepping Trail Making Test (S-TMT). The implementation rate of the S-TMT in the comprehensive geriatric survey was 99.1%. The S-TMT had good reproducibility. The S-TMT was a dual-task test that evaluates mobility as motor function and visual-dependent executive function as cognitive function. In addition, the discriminative and predictive power of the S-TMT for the global cognitive decline were superior to those of motor or cognitive function assessments in isolation.

Academic Significance and Societal Importance of the Research Achievements

これまでの先行研究では、運動・認知二重課題評価の全般的認知機能に対する判別または予測力は、運動または認知機能単独評価よりも優れるかどうか不明であった。本研究は、S-TMTによる運動・認知二重課題評価が、運動または認知機能単独評価よりも全般的認知機能低下者をより高い精度で判別・予測する能力があることを初めて報告した。S-TMTは、省スペースで簡便に、楽しみながら実施できる有用なテストとして、介護予防または保健事業等での活用が期待できる。
