In the early stage, we developed an intelligent measurement APP for diabetic foot ulcers, named Diabetic Foot Smart APP. This study aimed to validate the APP in the measurement of ulcer area for diabetic foot ulcer (DFU).
We selected 150 DFU images to measure the ulcer areas using three assessment tools: the Smart APP software package, the ruler method, and the gold standard Image J software, and compared the measurement results and measurement time of the three tools. The intra-rater and inter-rater reliability were described by Pearson correlation coefficient, intra-group correlation coefficient, and coefficient of variation.
The Image J software showed a median ulcer area of 4.02 cm, with a mean measurement time of 66.37 ± 7.95 s. The ruler method showed a median ulcer area of 5.14 cm, with a mean measurement time of 171.47 ± 46.43 s. The APP software showed a median ulcer area of 3.70 cm, with a mean measurement time of 38.25 ± 6.81 s. There were significant differences between the ruler method and the golden standard Image J software (Z = -4.123, p < 0.05), but no significant difference between the APP software and the Image J software (Z = 1.103, p > 0.05). The APP software also showed good inter-rater reliability and intra-rater reliability, with both reaching 0.99.
The Diabetic Foot Smart APP is a fast and reliable measurement tool with high measurement accuracy that can be easily used in clinical practice for the measurement of ulcer areas of DFU.

在早期阶段，我们开发了一种名为 Diabetic Foot Smart APP 的智能测量 APP，用于测量糖尿病足溃疡（DFU）的溃疡面积。本研究旨在验证该 APP 在 DFU 溃疡面积测量中的应用。
我们选择了 150 张 DFU 图像，使用三种评估工具：Smart APP 软件包、尺子法和金标准 Image J 软件测量溃疡面积，并比较了三种工具的测量结果和测量时间。采用 Pearson 相关系数、组内相关系数和变异系数描述内部和外部的可靠性。
Image J 软件显示的溃疡面积中位数为 4.02cm，平均测量时间为 66.37±7.95s。尺子法显示的溃疡面积中位数为 5.14cm，平均测量时间为 171.47±46.43s。APP 软件显示的溃疡面积中位数为 3.70cm，平均测量时间为 38.25±6.81s。尺子法与金标准 Image J 软件之间存在显著差异（Z=-4.123，p<0.05），而 APP 软件与 Image J 软件之间无显著差异（Z=1.103，p>0.05）。APP 软件也表现出良好的内部和外部可靠性，两者均达到 0.99。
Diabetic Foot Smart APP 是一种快速、可靠、测量精度高的测量工具，可在临床实践中轻松用于测量 DFU 的溃疡面积。
