@article{Pattnaik_Kim_2011, title={New approach to model the hand-arm system for analysis of musculoskeletal disorders}, volume={39}, url={https://jcaa.caa-aca.ca/index.php/jcaa/article/view/2354}, abstractNote={A new analysis approach is developed for hand-arm vibration analysis of musculoskeletal disorders. At a given equilibrium point, the musculo-tendon system can be interpreted as a spring damper system. It is considered that the Flexor Digitorum Profundus (FDP) and Lumbrical (LU) are participating in the response to the vibration force. The study shows that realistic muscle models should be included in the vibration analysis of the hand-arm exposed to tool vibration. The hand-arm system is found to have a redundancy in muscles because it has many more muscles than the minimum number required to establish equilibrium in gripping. An important observation is that bigger extrinsic muscles carry most of the static load to generate the grip force, and smaller muscles carry most tool vibration force at high frequencies.}, number={2}, journal={Canadian Acoustics}, author={Pattnaik, Shrikant and Kim, Jay}, year={2011}, month={Jun.}, pages={54–55} }
