An evaluation method on hand function to accomplish specific tasks

Currently evaluation of hand function is mainly based on scales, but it is unattached with objective measurement results and the classification boundary of ability to complete specific tasks is not obvious. This paper presented an evaluation method on hand function to accomplish specific tasks with standard posture, and figured out that the angle of finger joint showed obvious regularity in accomplishing different difficulty levels of specific tasks. Based on the reference standard concluded, we can predict the hand potential ability to complete various tasks in the scales through joint angles measured, finally improving the quantitative level and statistical efficiency of scales.
