Consideration of measurement error on device for quantitative evaluation of adjustability for grasping force

Abstract

We are aiming for develop device for adjustability for grasping force that useful for both training and quantitative evaluation as finger motion function. Therefore, we measured measurement error from 19 healthy subjects in order to obtain an indicators on the quantitative evaluation of adjustability for grasping force. We used the Bland-Altman analysis for consideration. As a result, when measured at intervals of 2 days or more and 7 days or less, there was no systematic error and it was revealed that there was only accidental error. And using this measurement result, we created standard data and confirmed reproducibility of measurement protocol.
