Modeling and Analysis of Human Jump Dynamics for Future Application in Exoskeletons

Due to the high rate of accidents causing motor and neural injury, the number of victims with partial or total gait loss has been increasing. One of the main traumas is the spinal cord injury, which can cause paraplegia. Researchers face challenges to assist in the development of rehabilitation techniques, provide better living conditions for these individuals, and help in the reintegration into society. Exoskeleton are promising technological innovations and could be used here. Thus, the objective of this work was to perform a biomechanical and dynamic analysis of human gait, represented by a simple spring mass system, initially analyzing the jump. We used Matlab^® to perform algebraic calculations, implement the algorithm, and data analysis. The results successfully showed the displacement behavior, speed, and power of the system to perform the jump, as well as the possibility of defining the best parameters for modeling and verification of physical and physiological limitations.
