Outline of Final Research Achievements

This research aimed to clarify human hand function by analyzing its movement with coupled joint range of motion (ROM) model. As grasping is essential for daily activity, we first captured and observed postures to grasp variously-sized objects. While grasping, an object applies external force to the hand, which leads to postures not only in active ROM but also in passive ROM. According to our analysis, such extension happened not uniformly but in specified joints such as metacarpo-phalangeal joint of the thumb. We also developed fingertip reachability expression considering coupled joint movement. As this metric describes the hand function in working space, it is expected to be applied to the hand function evaluation.
