The primary purpose of this study was to clarify the occurrence of sites of edematous changes using the measured circumferences of the thigh and lower leg via three-dimensional (3D) body scanning. The secondary purpose was to determine the relationship between the volume changes using 3D body scanning and the resistance changes as indicator of extracellular water (ECW) via segmental-bioelectrical impedance spectroscopy (S-BIS). Fifteen healthy women participated. Limb circumferences were measured using 3D body scanning at 10% intervals between 50% and 80% in the thigh circumference and between 0% and 80% in the lower leg circumference. The resistance of the ECW component (R) and total body water (R) was measured using S-BIS in the thigh and lower leg segments. These measurements were conducted at baseline and 6 hours postobservation. A paired -test was conducted for the differences in these parameters, and the effect sizes (ESs) were calculated using Cohen's . Correlations between changes in segmental volume and R were analyzed. Measurement-site circumferences and segmental volume significantly increased in the lower leg at postobservation but not in the thigh. The ES of circumference changes in the lower leg's central region were larger (ESs were 0.40-0.71 at 30%-50%) than in other regions. A significant correlation was observed between changes in segmental volume and R of the lower leg (ρ = -0.79, < 0.001). Assessing the circumference using 3D body scanning, we found the edematous changes to be significant in the lower leg's central regions. Moreover, volumetry using 3D body scanning can detect edematous change in the lower leg.
本研究的主要目的是通过三维（3D）体扫描测量大腿和小腿的周长，明确水肿变化部位的发生。次要目的是通过节段生物电阻抗谱（S-BIS）确定 3D 体扫描体积变化与作为细胞外液（ECW）指标的电阻变化之间的关系。 15 名健康女性参与了研究。在大腿周长的 50%至 80%和小腿周长的 0%至 80%之间的 10%间隔处，使用 3D 体扫描测量肢体周长。使用 S-BIS 在大腿和小腿节段测量 ECW 成分（R）和全身水（R）的电阻。这些测量是在基线和观察后 6 小时进行的。对这些参数的差异进行配对检验，并使用 Cohen's 计算效应大小（ES）。分析了节段体积变化与 R 之间的相关性。观察后，小腿的测量部位周长和节段体积显著增加，但大腿没有。小腿中央区域周长变化的 ES 较大（ES 在 30%-50%时为 0.40-0.71）。小腿节段体积变化与 R 之间存在显著相关性（ρ=-0.79， < 0.001）。 通过使用 3D 体扫描评估周长，我们发现小腿中央区域的水肿变化明显。此外，使用 3D 体扫描的容积测量可以检测到小腿的水肿变化。
