The original model describing planar movement dynamics of upper limb is presented. The upper limb is modelled as two-joints system loaded by external forces and internal forces of striated skeletal muscles. A behaviour of each muscle is modelled as a system composed of serially linked rheologic fragments that have different mechanical properties. These muscle models allow us to simulate a behaviour of short fusiform muscle (3DOF model), average fusiform muscle (5DOF model) and long fusiform muscle (7DOF model). The upper limb is modelled as a double pendulum (2DOF model) and a double pendulum in a planar movement (4DOF model). Taking into account in a model of upper limb dynamics an influence of: a) single short fusiform muscle model, one can obtain a model of upper limb dynamics increased by two degrees of freedom; b) single average fusiform muscle model, one can obtain a model of upper limb dynamics increased by four degrees of freedom; c) single long fusiform muscle model, one can obtain a model of upper limb dynamics increased by six degrees of freedom. The problem of control of upper limb dynamics model is also considered in a paper.
