Estimation of the Abduction/Adduction Movement of the Metacarpophalangeal Joint of the Thumb

Datasets analyzed in the study "Estimation of the Abduction/Adduction Movement of the Metacarpophalangeal Joint of the Thumb". Dataset contains kinematic data from thumb joints, and recorded by a Vicon motion capture system : Data used in the Experiment A (called as ExperimentA). Data used in the Experiment B (called as ExperimentB_1 and ExperimentB_2). ExperimentB_1 contains reach-to-grasp movements from 226 trials in experiment A: 9 subjects, reach-to-grasp movement of seven objects (book, cylinders, tennis ball and wallet, 3 repetitions of each). ExperimentB_2 contains grasping postures: 5 subjects, 7 cylinders of different sizes, 4 grasp types (cylindrical, five-finger, three-finger, two-finger grasp), 3 repetitions of each本研究所分析的数据集源自题为《拇指掌指关节（metacarpophalangeal joint）外展/内收运动评估》的研究。该数据集包含拇指关节的运动学数据，由Vicon运动捕捉系统（Vicon motion capture system）采集。 数据集涵盖实验A（记为ExperimentA）所用数据，以及实验B的两组数据（分别记为ExperimentB_1与ExperimentB_2）。其中ExperimentB_1包含源自实验A的226次伸手抓握运动试验数据，涉及9名受试者、7类物体（书本、圆柱体、网球与钱包），每类物体重复3次实验。ExperimentB_2则收录抓握姿态相关数据：共5名受试者参与，使用7种不同尺寸的圆柱体，涵盖4种抓握类型（圆柱形抓握、五指抓握、三指抓握、两指抓握），每种抓握类型重复3次实验。
