生物阻抗谱（BIS）经常用于监测健康和临床人群的体液和身体成分。BIS指南指出，电极部位不应有皮肤损伤，如果存在损伤，则应改变电极位置。然而，替代电极位置尚未报告。本研究旨在确定腹侧电极放置是否是全身和节段BIS测量的合适替代方案。使用腹侧手部和足部电极放置的组合，评估全身BIS的三种替代电极放置。评估了上半身和下半身节段性BIS的替代位置。结果表明，对于全身BIS，如果手上的驱动和感知电极移动到腹侧位置，但脚电极保持在标准位置，则全身BIS变量与标准电极定位相当（百分比差异范围= 0.01 - 1.65%，p = 0.211-0.937）。上肢节段性BIS的替代电极放置导致BIS变量与标准定位相当（百分比差异范围= 0.24- 3.51%，p = 0.393-0.604）。备用下肢电极位置显着改变了全身和下肢节段性BIS的所有电阻和预测BIS变量（百分比差异范围= 1.06- 12.09%，p < 0.001）。如果手部和/或腕部存在伤口，则本研究中描述的替代电极位置对全身和上肢节段性BIS有效。
Bioimpedance spectroscopy (BIS) is frequently used to monitor body fluid and body composition in healthy and clinical populations. BIS guidelines state that there should be no skin lesions at the site of electrodes, and if lesions are present, electrode positions should be changed. However, alternate electrode positions are yet to be reported. This study aimed to determine if ventral electrode placements were suitable alternatives for whole body and segmental BIS measurements. Three alternate electrode placements were assessed for whole body BIS using a combination of ventral hand and foot electrode placements. An alternate position was assessed for upper and lower body segmental BIS. The results demonstrated that for whole body BIS, if drive and sense electrodes on the hand are moved to ventral positions, but foot electrodes remain in standard positions, then whole body BIS variables were comparable to standard electrode positioning (percentage difference range = 0.01 to 1.65%, p = 0.211-0.937). The alternate electrode placement for upper limb segmental BIS, results in BIS variables that are comparable to that of the standard positioning (percentage difference range = 0.24-3.51%, p = 0.393-0.604). The alternate lower limb electrode position significantly altered all resistance and predicted BIS variables for whole body and lower limb segmental BIS (percentage difference range = 1.06-12.09%, p < 0.001). If wounds are present on the hands and/or wrist, then the alternate electrode position described in this study is valid, for whole body and upper limb segmental BIS.
