Objectives: This research is about the reliability of pulse wave analyzer and heart rate variability analyzer which are often used in the oriental medical clinics. Materials and Methods: Pulse wave analyzer and heart rate variability analyzer's reliability were compared with other devices-bioelectrical impedance analyzer, thermographer and transcranial sonography-. For each device, they were measured three times in a row. Here are the results of measuring intraclass correlation coefficients between first and second, and the ones between first and third. Results: 1. For pulse wave analyzer, seven items are higher than 0.7 in intraclass correlation coefficients, fourteen items are higher than 0.5 and eleven items are higher than 0.5. 2. Heart rate variability analyzer show that an item is higher than 0.9 and two are higher than 0.7. three items are higher than 0.5 and four are lower than 0.5. 3. For bioelectrical impedance analyzer, thermographer and transcranial sonography, nineteen items are higher than 0.9 and two are higher than 0.7. Conclusion: Pulse wave analyzer and heart rate variability analyzer showed low test-retest reliability compared to the one of bioelectrical impedance analyzer, thermographer and transcranial sonography. But both of analyzer's reliability are more than midium quality. Diagnosis trough these analyzers have a utility value. More research will be needed.
