SOLUTIONS TO IMPROVE MOBILITY OF THE PLASTER WALKING BOOT IN PATIENTS WITH PATHOLOGIES OF THE LOWER LIMB

Adrian Ioan BOTEAN

Abstract


In this paper, two technical solutions are proposed to improve the mobility of the plaster walking boot in the case of patients with pathologies of the lower limb. Having as reference element the concepts of biomimicry and bionics, an analysis of the principle of locomotion in the animal kingdom (kangaroo) is made. Based on an extensive bibliographic study, the distribution of the load distributed in the contact area between the plastered boot and the bionic displacement system is defined. Using the finite element method, the two proposed bionic systems are modeled in order to determine the laws that govern the distribution of efforts (forces and moments). Knowing the laws of variation and the size of the efforts, the elements that make up these bionic displacement systems can be optimally dimensioned (from the condition of strength, rigidity, stability and / or economy).
