Reliability of a new practical evaluation method for pitting edema based on the depth of the surface imprint

[Purpose] To develop and verify the reliability of a new practical evaluation method for pitting edema, which uses the depth of the surface imprint as an indicator. [Subjects] We included 26 inpatients (52 legs). [Methods] The subjects were diagnosed with edema, and we verified the inter- and intra-rater reliabilities of the edema gauge using intraclass correlation coefficients. [Results] For the first and second measurement values and the measured values between the examiners, the intraclass correlation coefficients were high. [Conclusion] Therefore, our findings suggest that the edema gauge, which measures the depth of the surface imprint, has sufficient intra- and inter-rater reliabilities.
