Strategies to evaluate musculoskeletal disorders to the human arm hand system using similarity metrics

The study of the behavior of the hand-arm system can present quantitative knowledge through the overall A(8) daily vibration exposure with the possibility of establishing significant properties of the state and output of the hand-arm system. The present research proposes the qualitative and quantitative analysis of the asymptotic behavior of the arm system by Popov’s theorem. The hand-arm system consists of subsystems, such as the operator’s fingers, wrist, el bow, and shoulder. The back offers a support structure to the arm-hand system. Using Popov’s theorem, the study of stability allows the evaluation of the stability of the individual subsystems in the presence of vibrations
