Objectives: The repeatability and reproducibility of MIR-2, a newly developed impedance measurement device (four electrode method) on skin are of the meridian system, is evaluated and a method to improve the reliability is discussed. Methods: Multiple gage R&R studies were conducted for the impedance measurements over bilateral KI3 acupoint in ten participants by three assessors using MIR-2 device. Gage R&R studies were repeated after controlling the acupoint locating method or one value correction by replacing one assessor`s outlying value with an average of the other assessors` values to explore any feasibility of improvement of measurement reliability. Results: Controlling acupoint locating method and replacing one value with an average of other assessors` value led to improved variation metrics in a gage R&R study. Conclusions: Measurement reliability can be improved by controlling measurement procedures or by using repeated measurement method, which will facilitate development of clinically applicable measurement device with reliability.
