摘要

Background and Purposes: Water displacement, circumference measurement and tissue tonometry are important clinical evaluation methods for the lymphedemous limbs. However, there are insufficient studies to investigate their reliability, and the measuring procedures are not standardized. The purposes of this study were to investigate the reliability of these measuring methods and to compare two kinds of tissue tonometry methods using standard tonometer and modified tonometer. Methods: This study recruited 32 upper extremities for water displacement and circumference measurement and 20 upper extremities for tonometry. Two investigators involved in each evaluation method. Results: The intra-rater reliability and inter-rater reliability of the water displacement and circumference measurement were high (ICC=0.99, p＜0.05). The coefficient of variation of both tonometry methods were ranging from 0.04 to 0.65. Intra-rater coefficients of variation were lower than that of inter-raters'. The coefficients of variation were lowest measured at forearm in comparison of at dorsum of hand and finger. Coefficients of variation of modified tonometry were lower than standard tonometry. Conclusion: Water displacement and circumference measurement have good reliability in measuring healthy subjects. The modified tonometry was more accurate, but took much time and effort to use it.
