The aim of this paper was to examine the reliability and validity of a new measurement device that counters the disadvantages of the traditional method of arm circumference measurements.
We measured the arm on the non-operated side of breast cancer patients. Sixty-four patients were measured twice by the same assessor and 48 patients were measured twice by two different assessors. The arm circumferences were measured at the olecranon and each 4 cm proximal and distal of the olecranon. The measurements were performed with a self-developed device consisting of a stainless steel bar on which a tapeline was fixed at every 4 cm distance. The arm volume was calculated from the circumference measurements with the frustrum formula and was also measured directly with the water displacement method.
For the circumference measurements, intrarater and interrater ICCs ranged between 0.942 and 0.998. ICCs for the calculated arm volume were also very high. No systematic changes between the first to the second assessment could be found. The standard error of measurement for the circumference measurements as well as for the calculated arm volume was low (between 0.8% and 2.0%). An increase of 1.0 cm or more of the arm circumference at any measurement side and of 55 ml or more of the calculated arm volume was clinically significant.
Arm circumferences and also the calculated arm volume can be measured quickly and accurately with a simple and inexpensive device.
本文旨在检验一种新型测量装置的可靠性和有效性，该装置克服了传统臂围测量方法的缺点。
我们对乳腺癌患者未手术侧的手臂进行测量。64名患者由同一名评估者测量两次，48名患者由两名不同的评估者测量两次。在鹰嘴处以及鹰嘴近端和远端每4厘米处测量臂围。测量使用自行研制的装置进行，该装置由一根不锈钢棒组成，在上面每隔4厘米固定一条卷尺。根据测量的周长用截头圆锥公式计算手臂体积，同时也用排水法直接测量手臂体积。
对于周长测量，评估者内和评估者间的组内相关系数（ICC）在0.942至0.998之间。计算得到的手臂体积的ICC也非常高。在第一次评估和第二次评估之间未发现系统性变化。周长测量以及计算得到的手臂体积的测量标准误差较低（在0.8%至2.0%之间）。在任何测量部位，臂围增加1.0厘米或更多，以及计算得到的手臂体积增加55毫升或更多具有临床意义。
使用一种简单且廉价的装置可以快速、准确地测量臂围以及计算得到的手臂体积。
