The human skeleton from mechanical point of view is a multi degree of freedom system supporting
structure. Depending upon the fact whether the muscle groups are tightened, the supporting
structure can be either determinate structure or statically indeterminate structure. The
tightened muscles turn into the part of the supporting structure, the slack muscles make it possible
that the structure operates as a mechanism. In this paper the simplified kinematics model
of the lower limb and its analysis are presented.
