本文研制了三种测试方法来迅速地定量评价病人神经性假手的输入输出特性与抓握时的控制。每一测试是在行走时利用视觉跟踪使受试者控制抓力和手的张开(位置)。第一种测试方法能表明输入输出的静态特性,其输入是病人自身产生的一种缓慢改变的命令信号,输出为抓力和手的张开位置。在输入输出关系中,我们发现了非线性和某些突变的斜率,在有些例子中还须进行系统重调。当要抓的物体较大时,假手产生的抓力也较大。对某些受试者,其输入输出关系曲线的形状还随物体 This paper developed three test methods to quickly quantitatively evaluate the patient’s input and output characteristics of nerve prostheses and grip control. Each test uses visual tracking while walking to allow the subject to control the grip and hand opening (position). The first test method can show the static characteristics of the input and output, the input is a slowly changing command signal generated by the patient itself, the output is grasping force and hand open position. In the input-output relationship, we found the slope of the non-linearity and some mutations, and in some cases, the system retargeted. When you want to grasp the larger object, the hand grip generated greater grip. For some subjects, the shape of the input-output relationship curve follows the object
