ABSTRACT

Introduction: Biomechanics in Cuba is not alien to international reality. Despite the technological difficulties, advances in the field of research on the biomechanics of human walking generate greater contribution to medicine, a fact that reports research of valuable impact applicable to physical medicine and rehabilitation.
Objective: To propose the application of a mathematical model that contributes to the recovery of the biomechanical pattern of gait, in the hip joint in children with cerebral palsy, spastic diparesia.
Methods: A functional and mechanical exploration of the joint was performed under normal conditions, which included the bones, muscles and ligaments, as well as the movements that it undergoes, and make up the cycle of normal bipedal gait. A review of cerebral palsy (type of spastic diparesia) was made from its concept and generalities that describe the behavior of this pathology and its way of affecting the normal gait cycle.
Results: The approach of the equation that describes the movement had its bases in the Lagrangian dynamics, that is, in the Euler-Lagrange expression, and to give functionality to said model. A videographic study was conducted, which provided the necessary kinematic parameters.
Conclusions: Kinetic and anthropometric parameters, resulted in obtaining angular acceleration curves against time for patients, establishing a comparative framework of great importance for decision making in the field of physical medicine and rehabilitation, achieving greater efficiency in the recovery of these patients or for the development of new technologies.
