Synergic movement of finger’s joints provides human hand tremendous dexterities, and the detection of ki-nematics parameters is critical to describe and evaluate the kinesiology functions of the fingers. The present work is the attempt to investigate how the angular velocity and angular acceleration of the joints of index finger vary with re-spect to time during conducting a motor task. A high-speed video camera has been employed to visually record the movement of index finger, and miniaturized (5-mm diameter) reflective markers have affixed to the subject’s index finger on the side close to thumb and dorsum of thumb at different joint landmarks. Captured images have been re-viewed frame by frame to get the coordinate values of each joint, and the angular displacements, angular velocities and angular acceleration can be obtained with triangle function. The experiment results show that the methods here can detect the kinematics parameters of index finger joints during moving, and can be a valid route to study the motor function of index finger.
