The relationship between the trajectories of the pressure center (CoP) and the Mass Center (CoM) is determinant for the human stability during gait. To understand the relationship between these trajectories it is necessary to access the coordinating pattern that is maintained during the performance of this daily activity. Nonlinear dynamics and dynamical systems approaches and methodologies are increasingly being implemented in biomechanics and human movement coordination research. Therefore, the aim of this preliminary study was to investigate the coordinative patterns between the movements of the CoP and the CoM during the human gait, So that in the near future it is possible to propose a new gait stability criterion based on this approach. Using the kinematics and dynamometry, the CoP and CoM trajectories were calculated and then using the continuous relative phase method (CRP) the coordinative patterns of one subject were obtained in 3 gait attempts. The phenomena analyzed showed similarity of amplitude and in the temporal location. The variability of the coordinative patterns was also calculated and this variable inspires the continuity of the study with different samples.
