Abstract. We have recently studied the rapidly increasing stroke in the elderly.
Stroke focuses on extracting meaningful variables for early diagnosis because
early diagnosis has a strong influence on the survival probability. Therefore, we
proceeded as follows. We measured vital signs and motion data from 80 stroke
patients and 50 normal elderly. This study is part of a study to compare the data
patterns of the elderly people by measuring daily life data, motion data, body
pressure, EEG (electroencephalogram), ECG (Electrocardiogram), EMG (elec-
tromyography), GSR (galvanic skin reflex) data of stroke patients. We experi-
mented with scenarios (walking, moving objects, sitting, etc.) to get natural
daily data from stroke patients.
We found that the data of the stroke patients and the normal elderly group
were clearly differentiated by the R-R interval parameter of the ECG data and
the brain wave data of the frontal and temporal lobe among the EEG data
(p < 0.05). These features are analyzed to develop algorithms that can detect
strokes early, compared with the conventional NIHSS questionnaire to deter-
mine stroke patients or the way physicians diagnose. In addition, the bio-signal
data is extracted from the experiment, and a judgment model is established by
taking the data of the participant’s 10-year health examination together. This
data includes various screening data such as height, smoking, exercise,
triglyceride, LDL-cholesterol, and HDL-cholesterol.
In addition to analyzing these vital signs and analysis data, we are analyzing
the cohort data of 2.5 million health checkup patients in the stroke patients
group to improve the accuracy of the diagnostic algorithm by extracting the
factors influencing the stroke.
The purpose of our research is to detect stroke in advance using big data and
bio-signal analysis technology, and contribute to human health promotion. The
data we are measuring is the data that elderly people often live in daily life. In
this experiment, data were measured with professional measurement equipment,
but items measurable in wearable device were selected for future service com-
mercialization. Because, in the future, the patient must be informed about his or
her health condition before going to the hospital. Therefore, if we introduce the
early detection algorithm of stroke, we think that many people will be able to
detect the stroke early and save many lives without going to the hospital.
