RESUMO:

Traditional methods employed in the study of motor control and biomechanics have used linear relationships between system components. However, these relationships go beyond the linear equations can offer (growth, decay and steady state maintenance), requiring an approach that explores the richness of the interaction of the motor system elements. The theory of complex systems applied to movement science has brought a new perspective to this last field of knowledge and may be another way of trying to explain the result that arises from the interaction of the elements of the neuromuscular system. Assuming the applicability of the theory of complex systems for understanding the behavior motor, this thesis’s general aim is to understand the behavior of human movement of the lower limbs through scaling measures. The scope review mapped the literature of scaling methods applied to the analysis of gait and running and the results showed a wide range of conceptual interpretations of metrics and methods used and different assumptions of motor explanation for the results of the work. Eleven scaling methods and 6 metrics associated with them were found. The analysis of the relationship between methods and motor interpretation showed that most of the papers uses the Detrended Fluctuation Analysis (DFA) and explains the DFA results through hypotheses about the supraespinal influence and origin of long-range correlations adaptability and stability during gait and running. The results contributed to the suggestion of new research that can answer questions that are still open in the literature. The last chapter is a cross-sectional study in which various lower limbs tasks are assessed to verify if there is nonlinear relationship between the average velocity of motion and displacement elements. It was found that the nonlinear relationship is present in the task, but changes according to the type of task and restrictions imposed on the task. Nonlinearity can stem from the central nervous system's priority in fulfilling the task objective and the fractal property of human movement. The hypothesis that explains the difference in scaling ratio between different tasks and under restrictions, is changing the attentional focus during activities. The scaling methods can be useful for measuring human movement and should be further explored to deepen understanding of human movement, as well as serve as an assessment tool to identify and monitor movement disorders and help in the treatment of these.
