The objective of this study was to investigate how the kinematic parameters of the human index finger have influenced the manipulability of the tip of the index finger. The subjects were the fourteen healthy males, aged 21 to 25. The flexion and extension of the index finger of the subjects was measured using a 3-dimensional motion measurement system (OPTOTRAK3020, Northern Digital Inc.). The cooperation between the proximal interphalangeal (PIP) joint angle and the distal interphalangeal joint angle during the flexion and extension of the index finger was determined based on the measurement results. It was possible that the motion of the tip of the index finger was controlled by the angular velocity input whose size was minimum.
