Measurements of the hand are common in studies that use anthropometric data. However, despite widespread usage, relatively few studies have formally assessed the degree of measurement error associated with standard measurements of the hand. This is significant because high amounts of measurement error can invalidate statistical results. In this paper, intraobserver precision estimates for measures of total hand length and total 3rd-digit length were evaluated from repeated measures on 90 subjects (180 separate hands and fingers). From this replicate data, three precision estimates were calculated: the technical error of measurement (TEM), the relative technical error of measurement (rTEM), and the coefficient of reliability (R). For both measurements, all three estimates yielded a very high degree of precision (TEM < 2 mm, rTEM < 1%, and R > or = 0.95). These results suggest that both total hand length and 3rd-digit length are sufficiently precise for anthropometric research applications.
手部测量在使用人体测量数据的研究中很常见。然而，尽管应用广泛，但相对较少的研究正式评估了与手部标准测量相关的测量误差程度。这很重要，因为大量的测量误差会使统计结果无效。在本文中，通过对90名受试者（180只手和手指）的重复测量，评估了观察者内手部总长度和第三指总长度测量的精度估计。根据这些重复数据，计算了三个精度估计值：测量技术误差（TEM）、相对测量技术误差（rTEM）和可靠性系数（R）。对于这两种测量，所有三个估计值都产生了非常高的精度（TEM<2毫米，rTEM<1%，R≥0.95）。这些结果表明，手部总长度和第三指长度对于人体测量研究应用来说都足够精确。
