Proficiency Assessment in Repetitive Pick-and-place Movements

Abstract

The Pick-and-place movements are used in the fields of light work and rehabilitation, but the evaluation method of the movements is based on the number of times and time, and the results may change depending on the subject’s intention. In this study, we used a synchronous pick-and-place movement to extract the temporal fluctuations of movements, and we investigated the degree of proficiency of the movement by focusing on the body control system. As a result of the experiment, it was shown that there is a relationship between the trigger period, which represents the frequency of pick-and-place, and the proficiency in the pick motion.
