Edema development of the foot and ankle region should be evaluated by an objective measurement. We hypothesized, that 3D optical scanning of this region can serve as an alternative to clinically established measurement techniques.
Two investigators determined the volume by 3D optical scanning and the figure-of-eight method in a random order at 2 separate time points. Plots were created and ICCs were calculated for determination of reliability. The Pearson correlation coefficient served as a measure of the association between both measures.
40 healthy volunteers with mean age of 28.3±9.9 years underwent four sequences of measurements. The inter- and intraobserver reliability of both methods was excellent with high intraclass correlation coefficients (ICC 3,1). A strong correlation (r=0.96, P<0.001) between measured ankle volumes was noted.
3D optical scanning turned out to be more reliable than the figure-of-eight method in a preclinical set-up. A clinical use should be aimed at.
足踝部水肿的发展情况应通过客观测量来评估。我们推测，该区域的三维光学扫描可作为临床既定测量技术的替代方法。
两名研究人员在两个不同时间点以随机顺序通过三维光学扫描和“8”字测量法确定体积。绘制图表并计算组内相关系数（ICC）以确定可靠性。皮尔逊相关系数用作两种测量方法之间关联程度的指标。
40名平均年龄为28.3±9.9岁的健康志愿者接受了四次测量。两种方法在观察者间和观察者内的可靠性均极佳，组内相关系数较高（ICC 3,1）。观察到测量的踝关节体积之间存在强相关性（r = 0.96，P < 0.001）。
在临床前设置中，三维光学扫描比“8”字测量法更可靠。应致力于临床应用。
