1999 International Journal of Occupational Safety and Ergonomics  
The aim of this research was to develop a theoretical m ethod fo r the ergonom ic optim ization of the w ork space of the upper limb. This method is based on a model o f the upper extremity with 7 degrees of freedom. It consists of 3 rigid elements modeling the arm, forearm, and hand and 34 upper extremity muscles. The trunk is considered immobile. The shoulder jo in t is m odeled as a rotating kinem atics pair of third class, the elbow and wrist joints-o f fourth class. The m inim um sum of
more » ... m inim um sum of muscle force moments in the join ts and soft sa turation muscle cooperation criterion were used as merit criteria. The developed method makes it possible to effectively solve, in a defined w ork space, the task of w ork space optim ization. w ork space optim ization com puter m odeling upper extremity
