The main aim of the article is to define a criterion of dynamic stability based on the Flash-
Hogan principle and the ZMP method. The gait researches were focused on analysis and
observation of the human biomechanism with the optical system Optitrack. The smooth
reference trajectory is defined forming a stability pattern. The optimal, due to the minimum
jerk criterion, ZMP trajectory is illustrated in the results Section in order to demonstrate the
dynamic stability pattern for the needs of rehabilitation in cases of neuromuscular damage
or injuries affecting gait stability.
