Brain dysfunction assessment method, brain dysfunction assessment device, and program thereof

A program for causing a data processing device connected to a body movement presenting device for presenting a body movement to be executed by a subject, and to a body movement detection sensor for detecting execution data of a body movement executed by the subject according to the presented body movement, to execute:

• a body movement instruction step of generating body movement instruction data of a body movement to be executed by the subject, and presenting a body movement that is based on the generated body movement instruction data, via the body movement presenting device to the subject, to instruct execution of the body movement;
• a body movement data acquisition step of chronologically acquiring, via the body movement detection sensor, body movement data of a body movement executed by the subject;
• a body movement accuracy calculation step of calculating a positional accuracy and a time-series accuracy of a body movement of the subject based on the body movement instruction data and the body movement data;
• and
• a cognitive impairment degree evaluation step of evaluating a cognitive impairment degree of the subject by comparing a value indicating an accuracy of a body movement of the subject that is obtained from the calculated positional accuracy and time-series accuracy, with statistical data indicating an accuracy of a body movement of a healthy subject that has been acquired in advance.

A cerebral dysfunction evaluation apparatus comprising:

• a body movement presenting device configured to present a body movement to be executed by a subject;
• a body movement detection sensor configured to detect body movement data of a body movement executed by the subject according to the presented body movement;
• and
• a data processing device connected to the body movement presenting device and the body movement detection sensor,
• wherein the data processing device includes:
• a body movement instruction unit configured to generate body movement instruction data of a body movement to be executed by the subject, and to present a body movement that is based on the generated body movement instruction data, via the body movement presenting device to the subject, to instruct execution of the body movement;
• a body movement data acquisition unit configured to chronologically acquire, via the body movement detection sensor, body movement data of a body movement executed by the subject;
• a body movement accuracy calculation unit configured to calculate a positional accuracy and a time-series accuracy of a body movement of the subject based on the body movement instruction data and the body movement data;
• and
• a cognitive impairment degree evaluation unit configured to evaluate a cognitive impairment degree of the subject by comparing a value indicating an accuracy of a body movement of the subject that is obtained from the calculated positional accuracy and time-series accuracy, with statistical data indicating an accuracy of a body movement of a healthy subject that has been acquired in advance.
