摘要

Completing a functional grasping task with five digits requires the control of numerous degrees of freedom in digit force. However, the waveform repeatability of applied force during such tasks remains unknown. This study aimed to analyze the waveform repeatability of force in each digit during grasping. Twenty right-handed subjects were recruited. The digit forces in radial and longitudinal directions during lift-hold-lower and drinking tasks were obtained by a custom simulator with five force transducers and one accelerometer. The repeatability was higher for radial than longitudinal force during the lift-hold-lower task. The repeatability of longitudinal force was higher during the drinking task than lift-hold-lower task. The fair to good repeatability of force waveform implies the flexibility in the control of digit forces to compensate for various task demands and coordinate with other digits in counterbalancing instantaneous changes of the object's gravity force in motion.
