Abstract

This paper describes a system for the quantitative analysis of posture and stance in the freely standing quadruped. The focal point of the system is a moving force platform operated by hydraulic servos under computer control. Cats are trained to stand on a support consisting of 4 force plates. Stance is perturbed by the controlled movement of the platform and the evoked postural responses are quantified in terms of the ground reaction forces, the activity of selected muscles, and the movements of the body segments. New developments that are described include: (1) the moving platform, (2) a miniature, triaxial force plate for detecting ground reaction forces under each paw, and (3) a new video camera capable of freezing rapid movements.

摘要

本文描述了一种用于对自由站立的四足动物的姿势和 stance 进行定量分析的系统。该系统的核心是一个由计算机控制的液压伺服驱动的移动力平台。猫被训练站在由 4 个力板组成的支撑物上。通过平台的受控运动对 stance 进行扰动，并根据地面反作用力、选定肌肉的活动以及身体各部位的运动对诱发的姿势反应进行量化。所描述的新进展包括：（1）移动平台，（2）用于检测每个爪子下方地面反作用力的微型三轴力板，以及（3）一种能够冻结快速运动的新型摄像机。
