Abstract
[Purpose] The purpose of this study was to investigate the interrelationships of assessments of motor imagery using different attributes. [Subjects] The subjects were 43 healthy persons. [Methods] Using the results of a paper questionnaire (VMIQ-2), mental chronometry tasks (iBBT and iTUG), and a mental rotation task (HLJT), we performed correlation and principal component analysis. [Results] We found correlations between VMIQ2-KI and VMIQ2-EVI, VMIQ2-IVI, iTUG, and HLJT. In principal component analysis, the major factors comprising the second principal component were VMIQ2-IVI, VMIQ2-KI, iTUG, and HLJT, and we consider that it is a principal component related to imagery of muscle sense. [Conclusion] In assessments of motor imagery ability, in addition to paper questionnaires, performance of iTUG and HLJT is useful.
