Abstract
The human spine is a complex structure that can present deformities like kyphoscoliosis (KS). The patients with KS often present chronic back pain (50% to 61%). The aim of this paper investigates if the seated position creates areas with concentrated stress in the upper body, contributing to their chronic back pain. In order to achieve this, a finite element analysis (FEA) was done of an individual with KS while seated in two conditions: first with a concentrated force provided by the backrest, then with a more distributed one. The analysis was made with the mechanical properties of the Skeletal Muscle. The images generated as a result of FEA shows that the superior part of the spine as well as the sacral part have low values of stress. The lower back region, on the other hand, presents itself as a stress raiser which may cause back pain. It was also observed that the less concentrated force generated a result with lower values for the stresses within the object, which sugests that a distributed force could collaborate for the decrease of the back pain.
