用逆动力学分析方法测定了3种小型兽形目哺乳动物（Scandentia：Tupaia glis，Rodentia：Galea musteloides和Lagomorpha：Ochotona rufescens）在站立期前肢（肩胛枢、肩关节、肘关节、腕关节）和后肢（髋关节、膝关节、踝关节、跖内关节）4个运动学相关关节的净关节力和力矩。通过放射性电影摄影（150帧/秒）测量运动。同时，地面反力由测力板获得。四肢的形态测量进行了扫描方法，使用结构照明。地面反力和重量矢量之和占关节力矢量的大部分。惯性效应可以忽略，因为净关节力的误差最多为10%。关节扭矩的一般时间过程是可比的所有物种在所有关节的前肢和踝关节。有尾和无尾物种的跗内关节扭矩不同。膝关节和髋关节的扭矩模式对于每个物种都是独特的。首次完整描述了前肢的扭矩模式，包括作为主要推进部分的肩胛骨。将结果与猫（Felis卡图斯）、狗（Canis lupus f. familiaris）、山羊（Capra sp.）和马（Equus przewalskii f.）caballus）。
In three species of small therian mammals (Scandentia: Tupaia glis, Rodentia: Galea musteloides and Lagomorpha: Ochotona rufescens) the net joint forces and torques acting during stance phase in the four kinematically relevant joints of the forelimbs (scapular pivot, shoulder joint, elbow joint, wrist joint) and the hindlimbs (hip joint, knee joint, ankle joint, intratarsal joint) were determined by inverse dynamic analysis. Kinematics were measured by cineradiography (150 frames s(-1)). Synchronously ground reaction forces were acquired by forceplates. Morphometry of the extremities was performed by a scanning method using structured illumination. The vector sum of ground reaction forces and weight accounts for most of the joint force vector. Inertial effects can be neglected since errors of net joint forces amount at most to 10 %. The general time course of joint torques is comparable for all species in all joints of the forelimb and in the ankle joint. Torques in the intratarsal joints differ between tailed and tail-less species. The torque patterns in the knee and hip joint are unique to each species. For the first time torque patterns are described completely for the forelimb including the scapula as the dominant propulsive segment. The results are compared with the few torque data available for various joints of cats (Felis catus), dogs (Canis lupus f. familiaris), goats (Capra sp.) and horses (Equus przewalskii f. caballus).
