Development of DFM(Double-Handle Force Measurement) System For Measuring Individual Finger Forces

다국어 초록 (Multilingual Abstract)

Objective: The purpose of this study was to develop DFM(Double-handle Force Measurement) System for measuring grip strength and individual finger force. Background: A handle shape has not been considered in man previous studies of grip strengths. Accordingly, Design of double-handle tools on ergonomic aspect have many limitations. Methods: In this study, five grip span of A-type was used for measuring total grip force, individual finger force, and finger force distributions. Ten males were recruited from University population for this study. Each participants were asked to exert their maximum grip strength with 3 repetitions for five grip spans(45, 50, 55, 60, 50mm). Results: The highest grip strength was performed on 45mm and 50mm grip spans. On the other hand, among the entire finger, middle and ring fingers showed the highest force as well as distribution to the total finger force. Discussions: The findings of this study might be important information, basically, for designing ergonomic doublehandle tool type.
