The paper presents the experimental approaches to mathematical model creation for the lower limb movement of a human's locomotor system. The experimental research data based on analysis of four persons manner  of walking has been used as initial conditions. The data has been obtained in the kinesiology and biomechanics laboratory of Tartu University, Estonia. The model has been constructed with the use of the measurement data of hip and knee flexion kinematic parameters. The frequency ratio of oscillatory  movements during the hip and knee flexion has been established.. The research has been performed on the "toe-to-ground contact" phase kinematics that gave the possibility to discover the constancy parameter being of great concern for the model of system with one degree of freedom (in the jump-off phase backed on the forefoot) and with two degrees of freedom (in transfer phase). We took into account elastic and viscoelastic model parameters in the calculation.

Keywords: lower limb mathematical model, step phases, biomechanics, elastic and viscoelastic model parameters, constancy parameter
