Acquisition of a Motion Analysis Facility for the Study of Primate Locomotion at SUNY, Stony Brook

在美国国家科学基金会的支持下，纽约州立大学石溪分校的灵长类动物运动实验室将获得仪器，以补充和提高他们研究灵长类动物运动的能力。购买3D运动分析系统将允许自动和手动跟踪肢体部分坐标，并将允许精确量化肢体部分的3D位移、速度和加速度。然后，这些数据将与肌电图数据、基底力和压力的动力学数据以及长骨负荷的应变数据进行协调。通过这笔拨款购买的压力板将用于确定手和脚接触处的压力分布。该实验室是美国为数不多的从事灵长类动物功能形态学实验分析的实验室之一，并在身体和灵长类动物的广泛解剖部位检查了肌肉和骨骼构象的功能。该小组计划进行一系列研究，包括：灵长类四足动物的运动学涉及骨应变研究，以确定个体间和肢间应变变化是否与肢体姿势差异相关。猴子和类人猿的攀爬运动学，以帮助确定攀爬适应是否导致了它们和古人类颅骨后形态的任何独特特征；3. 长臂猿和蜘蛛猴臂展运动的运动学和动力学4. 关节行走的运动学和动力学，以了解这种独特的运动适应在古人类树中的分布；这项研究将起到几个作用。它将为解析形式和函数之间的关系提供基本的见解。它还将为猿猴化石和人类化石的分析提供一个强大的数据库和出发点。许多来自大学内多个部门的研究人员以及研究生将受益于该仪器

With National Science Foundation support, the Primate Locomotion Laboratory at SUNY Stony Brook will acquire instrumentation to supplement and increase their capacity to study primate locomotion. Purchase of a 3D motion analysis system will permit automatic and manual tracking of limb segment coordinates and will allow accurate quantification of 3D displacements, velocities and accelerations of limb segments. These data will then be coordinated with EMG data on muscle recruitment patterns, kinetic data on substrate forces and pressures, and strain data on long bone loading. A pressure plate, also purchased through this grant will permit determination of pressure distribution at hand and foot contacts. The laboratory is one of a few in the US engaged in experimental analysis of functional morphology in primates and has examined the function of muscle and bone conformation across a wide range of anatomical parts of the body and primate species. The group plans to pursue a number of studies including: 1. the kinematics of primate quadrupeds involved in bone strain studies to determine if inter-individual and interlimb variations in strain correlate with limb posture differences: 2. the kinematics of climbing in monkeys and apes to help determine whether climbing adaptations are responsible for any of the unique features which distinguish are and fossil hominid postcranial morphology; 3. the kinematics and kinetics of gibbon and spider monkey brachiation; 4. the kinematics and kinetics of knuckle-walking to understand the distribution of this unique locomotor adaptation in the hominoid tree; The research will serve several functions. It will provide basic insight into the relationship between analytical form and function. It will also provide a powerful data base and point of departure for the analysis of fossil monkey ape and hominid remains. Many researchers from several departments within the university as well as graduate students will benefit from this instrumentation
