Clinical photonumeric scales have been developed and validated to objectively measure the effectiveness of aesthetic treatments in specific anatomical areas; however, these are based on the typical features of Caucasian patients. No clinical scale for Asian calf appearance currently exists.
To develop and validate a calf assessment scale for use in the female Asian patient population.
During 2 validation sessions, 13 raters assessed calf images of female Asian subjects (N = 35) viewed from behind with feet flat on the floor (at rest) and on tiptoes (dynamic). Images were rated from 0 (very slim, linear profile) to 4 (very severe convex profile).
Inter-rater and intra-rater reliability were "substantial" (≥0.6, intraclass correlation coefficient [ICC] and weighted kappa) for the calf-at rest, calf-dynamic, and calf summary score. Reliability was "substantial" for calf-at rest and calf-dynamic (≥0.6, ICC and weighted kappa) and "almost perfect" (0.85) for the calf summary score. BMI and calf circumference were highly correlated with scale ratings, and calf circumference was a significant predictor.
This new photonumeric assessment scale has value for assessing the female Asian calf, providing a standardized measure of calf appearance in clinical practice and clinical research settings.
临床光子数字量表已经被开发和验证，用于客观测量特定解剖区域美容治疗的效果；然而，这些量表基于白种人患者的典型特征。目前还没有针对亚洲小腿外观的临床量表。
开发和验证一种适用于亚洲女性患者群体的小腿评估量表。
在 2 次验证会议中，13 名评估者对从后面看的亚洲女性受试者的小腿图像进行了评估（N=35），图像中受试者的脚平放在地板上（休息时）和踮起脚尖（动态）。图像从 0（非常苗条，线性轮廓）到 4（非常严重的凸面轮廓）进行评分。
小腿在休息时、小腿在动态时和小腿总分的评估者间和评估者内可靠性为“中等”（≥0.6，组内相关系数[ICC]和加权 kappa）。小腿在休息时和小腿在动态时的可靠性为“中等”（≥0.6，ICC 和加权 kappa），小腿总分的可靠性为“近乎完美”（0.85）。BMI 和小腿围度与量表评分高度相关，且小腿围度是一个显著的预测因素。
这种新的光子数字评估量表对于评估亚洲女性的小腿具有价值，为临床实践和临床研究环境中的小腿外观提供了一种标准化的衡量标准。
