The purpose of this pilot study was to determine if body orientation, skin treatment, joint angle, and shoulder arch movements affect localized bioimpedance spectroscopy (BIS) measurement. Nowadays, there are various wearable and portable impedance measurement tools in different shapes and sizes. Therefore, the body position and orientation of the subject during measurement may be of great importance for the comparability of the results. Ultrasound machine was used to measure the thickness of the skin layers and then bioimpedance measurements were performed for ten young men (age=23 ± 5) at room temperature (22°C) for different body orientations, skin treatments, joint angle, and shoulder arch movements. The results were analyzed using statistical methods and graphical presentation using Python and MatLab. Our observations indicate that there is a significant difference between standing straight up, supine and sitting positions. The results show that there is a significant difference between the two skin treatments (alcohol vs tape stripping). Moreover, joint angle and shoulder arch movements also have an impact on the impedance data. Therefore, to be able to control these factors can potentially improve the quality and comparability of the measured impedance data.
这项初步研究的目的是确定身体方位、皮肤处理、关节角度和肩部弓状运动是否会影响局部生物电阻抗光谱（BIS）测量。如今，有各种形状和大小各异的可穿戴和便携式阻抗测量工具。因此，测量过程中受试者的身体位置和方位对于结果的可比性可能非常重要。使用超声仪测量皮肤层的厚度，然后在室温（22°C）下，针对十名年轻男性（年龄 = 23 ± 5），在不同的身体方位、皮肤处理、关节角度和肩部弓状运动情况下进行生物阻抗测量。使用统计方法对结果进行分析，并使用Python和MatLab进行图形展示。我们的观察结果表明，直立、仰卧和坐姿之间存在显著差异。结果显示，两种皮肤处理方式（酒精擦拭与胶带剥离）之间存在显著差异。此外，关节角度和肩部弓状运动也会对阻抗数据产生影响。因此，能够控制这些因素可能会提高所测阻抗数据的质量和可比性。
