Clinical Trial Evaluating an Online Cognitive Dysfunction Evaluation System for Stroke Patients

Abstract

[Purpose] The purpose of this study was to verify the validation and usefulness of an online cognitive examination system to measure the degree of cognitive deficits of stroke patients. [Subjects] To verify the usefulness of the online examination system, thirty-one stroke patients and twenty normal, healthy volunteers as an age-matched control group were recruited. [Methods] The thirty-one stroke patients were classified into three groups according to the severity of their cognitive dysfunction. To evaluate the reliability of the online system we compared the results of our system with the results of the Korean version of the Mini-Mental Status Examination (MMSE-K). [Results] There were significant correlations between the results of the evaluation by the online-based system and those of MMSE-K, and there were also significant differences between patient subgroups and the control group. [Conclusions] We have investigated the usefulness of an online evaluation system and verified its effectiveness in the screening of patients for cognitive dysfunction.
