在许多生物力学研究中,特别是步态分析中,获得身体节段参数(BSP)的准确值是基础。凸脱壳,其中最小可能的凸对象,周围的一组点计算,已被建议作为一种有效的和时间效率的方法来估计这些参数在灭绝的动物,其中软组织很少保存。我们研究了凸船体BSP估计在一系列现存哺乳动物中的有效性,以告知这种技术在灭绝类群中的潜在未来用途。计算机断层扫描的骨骼和皮肤的每一个物种的调查实际上是分段的。BSP(质量,质心的位置和惯性张量的每段)计算从所得的软组织段,而骨段被用作凸船体重建的基础。我们进行了系统发育广义最小二乘和普通最小二乘回归,比较从软组织段计算的BSP与使用凸包估计的BSP,为每个身体段找到一致的预测关系。由此产生的回归方程,因此,在未来的体积重建和哺乳动物的生物力学分析,在灭绝和现存的物种,这样的数据可能无法使用的信心。
Obtaining accurate values for body segment parameters (BSPs) is fundamental in many biomechanical studies, particularly for gait analysis. Convex hulling, where the smallest-possible convex object that surrounds a set of points is calculated, has been suggested as an effective and time-efficient method to estimate these parameters in extinct animals, where soft tissues are rarely preserved. We investigated the effectiveness of convex hull BSP estimation in a range of extant mammals, to inform the potential future usage of this technique with extinct taxa. Computed tomography scans of both the skeleton and skin of every species investigated were virtually segmented. BSPs (the mass, position of the centre of mass and inertial tensors of each segment) were calculated from the resultant soft tissue segments, while the bone segments were used as the basis for convex hull reconstructions. We performed phylogenetic generalized least squares and ordinary least squares regressions to compare the BSPs calculated from soft tissue segments with those estimated using convex hulls, finding consistent predictive relationships for each body segment. The resultant regression equations can, therefore, be used with confidence in future volumetric reconstruction and biomechanical analyses of mammals, in both extinct and extant species where such data may not be available.
