to evaluate the use of the 2D-FlexRuler as a facilitating tool for the early calculation of the predictive scar factor of chronic wounds.
a descriptive study with a quantitative, experimental, longitudinal and prospective approach. The sample consisted of 22 outpatients. 32 chronic wounds were analyzed. The wound edges were identified and drawn on the 2D-FlexRuler. The calculations of the areas of chronic wounds were obtained by manual, traditional methods, by software and Matlab algorithm. These areas were compared with each other to determine the efficiency of the proposed ruler in relation to traditional methods.
the calculation of the wound area by the traditional method and Kundin's coefficient show average errors greater than 40%. The manual estimation of the area with the 2D-FlexRuler is more accurate in relation to traditional measurement methods, which were considered quantitatively disqualified. When compared with the reference method, for example, the Klonk software, the data obtained by 2D-FlexRuler resulted in an error of less than 1.0%.
the 2D-FlexRuler is a reliable metric platform for obtaining the anatomical limits of chronic wounds. It facilitated the calculation of the wound area under monitoring and allowed to obtain the scar predictive factor of chronic wounds with precocity in two weeks.
评估二维柔性尺作为一种辅助工具用于早期计算慢性伤口预测性瘢痕因子的情况。
采用定量、实验、纵向和前瞻性的描述性研究方法。样本包括22名门诊患者，共分析了32处慢性伤口。在二维柔性尺上识别并绘制伤口边缘。通过手动、传统方法、软件和Matlab算法获得慢性伤口面积的计算结果。将这些面积相互比较，以确定所提出的尺子相对于传统方法的效率。
传统方法和昆丁系数计算伤口面积的平均误差大于40%。与被认为在定量方面不合格的传统测量方法相比，使用二维柔性尺手动估计面积更为准确。例如，与参考方法Klonk软件相比，二维柔性尺获得的数据误差小于1.0%。
二维柔性尺是获取慢性伤口解剖学边界的可靠测量平台。它便于计算监测中的伤口面积，并能在两周内提前获得慢性伤口的瘢痕预测因子。
