我们的目的是量化日本孕妇下躯干节段的惯性参数，并将使用本研究估计的参数计算的任务期间的动力学数据与使用标准参数计算的数据进行比较。八名孕妇和七名未产妇参加了研究。躯干下部贴有二十四个红外反射标记，八个红外摄像机捕捉到站立位置。将下躯干分为几部分，并计算惯性参数。孕妇执行一项运动任务，包括从椅子上站起来，拿起盘子，向右转后向前走。使用标准惯性参数和新计算的参数进行动力学分析。不同方法在妊娠后期的动力学数据差异更为显着。本研究中计算的惯性参数应用于确保日本孕妇生物力学研究的有效性。 (C) 2016 年作者。由爱思唯尔有限公司出版
We aimed to quantify the inertial parameters of the lower trunk segment in pregnant Japanese women and compare kinetic data during tasks calculated with parameters estimated in this study to data calculated with standard parameters. Eight pregnant women and seven nulliparous women participated. Twenty-four infrared reflective markers were attached to the lower trunk, and the standing position was captured by eight infrared cameras. The lower trunk was divided into parts, and inertial parameters were calculated. Pregnant women performed a movement task that involved standing from a chair, picking up plates, and walking forward after turning to the right. Kinetic analysis was performed using standard inertial parameters and the newly calculated parameters. There were more significant differences between methods in the kinetic data at the latter stages of pregnancy. The inertial parameters calculated in this study should be used to ensure the validity of biomechanical studies of pregnant Japanese women. (C) 2016 The Authors. Published by Elsevier Ltd.
