Impact of Effort Degree Developed in Fingers-Hand-Arm Assembly, on the Hand Dexterity. Case Study

Abstract

This paper presents some theoretical and practical aspects obtained from the analysis of upper limb movements under a controlled effort. For starters, the study of anatomical modeling of the upper limb components is necessary to identify sensitive areas in terms of normal stresses and dynamic overstressing of the joints respectively, or gripping area. Design and development of experimental approaches that emphasize these effects on joints, range of motion, or energy consumed during analysis constitute the second part of the work. Also, a particular interest is given to how to determine the level of dexterity by inducing a controlled effort. In the third part of the paper are presented the results and conclusions obtained after applying the methodology designed on a casuistry identified in the experimental procedures.
