Investigating the Effect of Gripping on Upper Limbs Muscles by Modeling and Electromyography Test

Abstract

These days most of the workers use hand controller tools. Because of this it is useful to know the relations between hand and these kinds of tools. One of these relations is cylindrical power grip. For this reason first of all a device is prepared for measuring the torque value. After that by creating a model in ANYBODY software for gripping motion for forces and muscular activities have been calculated. In this case for solving the inverse kinetic problem several cost functions are defined and the results are compared. On the other hand, by using Electromyography tests in gripping motion the activity of 3 surface muscles are investigated and finally the modeling and Electromyography’s results are compared.

Estimating the optimum exercise pattern in upper extremity using musculoskeletal modeling and genetic algorithm

“…For each joint, there is a redundant set of muscles implying a statically underdetermined system of equilibrium equations, i.e., inverse dynamic analysis in most cases, leads to indeterminate problem. Many research have been performed to determine the muscle forces and joint reactions in a specific musculoskeletal system during limited motion patterns [1][2][3][4][5], and numerous researchers tried to develop musculoskeletal models or compare different computational methods for analysing these models [6][7][8][9][10][11][12][13][14][15][16][17][18]. These efforts prepare valuable knowledge for modelling and analysing musculoskeletal systems.…”
