Objective To study the frequency and effective work/time ratio of pushing manipulation with one finger (PMOF). Methods One skilled expert and nine beginners of PMOF were chosen. The frequency, effective work time/ratio during different work periods were recorded and compared after the technique information of each subject operating PMOF was collected by Novel Pliance Mobile System software. Results The operation frequency of each subject was all below 110/min, while the frequency of skilled expert was about 78/min. The time ratio between secondary work period and primary work period for the skilled expert was smaller than that of beginners. Conclusions The operation frequency of PMOF is preferably at 78/min, and the preferred time ratio between secondary work period and primary work period should be slightly larger than 0.28.
