本文介绍了在伸展和抓握实验中观察到的五指掌指关节(MCP)和近端指间关节(PIP)的角速度分布的时变协同效应。五名右撇子受试者被要求接触并抓住28个不同的物体，在这个实验中，用数据手套测量关节角度。我们的结果表明，在28个不同的任务中，仅使用3个协同效应，就能准确地再现10个关节(每个手指2个)在0.86秒内的角速度分布。有趣的是，物体大小和速度分布之间存在相关性，这导致在实现自然运动的这些协同效应的组合中存在独特的区别。
This paper presents time-varying synergies that were observed during reach and grasp experiments in angular velocity profiles of metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints of five fingers of the hand. Five right handed subjects were asked to reach and grasp 28 different objects and during this experiment joint angles were measured by a data glove. Our results showed that the angular velocity profiles for a period of 0.86 seconds of ten joints (two per finger) were accurately reproduced by using only 3 synergies in 28 different tasks. Interestingly, there were correlations between the object size and velocity profiles which lead to unique distinctions in the combinations of these synergies in achieving the natural movements.
