Outline of Final Research Achievements

Two kinds of finger arteriolar dilatability testing (ADA) using one's hands and only one hand have been developed and registered as the domestic and international patent for comprehensive but simple non-invasive assessment of endothelial function and stiffness of finger artery which would be deteriorated by chronically accumulated stress in body and the early stage in arteriosclerosis.
In this study, the concurrent validity and consistency of the ADA with a finger probe weakly clamping the finger circumference to a medical standard test (Endo-PAT) were examined and their compatibility was confirmed using healthy young participants. Furthermore, significant associations were revealed between ADA and negative and positive personality traits of anger, depression, sense of coherence and subjective happiness in healthy young participants. In addition, ADA was useful for the evaluation of arterial health in clinical patients of diabetes and/or hypertension.
