THE BIOMECHANICAL REFLEXION OF MODERATE IDIOPATHIC SCOLIOSIS IN GAIT CYCLE OF YOUNG ADULTS

Abstract

Introduction: Scoliosis influences the optimal posture and locomotion of the human body. Lumbar and thoraco-lumbar scoliosis has possibly an even greater impact due to the close relation with the pelvic region, a major determinant of gait. The effect of moderate idiopathic scoliosis on the gait cycle of young adults is of major interesting. Discussion-Hypothesis and aims: Young adults (20-40 years old) with MIS (lumbar and thoraco-lumbar primary curves) present kinematic modifications regarding the convex (ipsilateral extremity) or concave (controlateral extremity) side of the body as well as variations compared to non-scoliosis individuals during the gait cycle. Aim of this study was to indentify these variations on the physical quantities exerted from the major joints of the lower extremities as well as the center of gravity too and examine their significance in adult patients with MIS. Materials and methods: A cohort of twenty young adult patients (group A, 12 females- 8 males, mean age 39,7 years) having MIS with mean Cobb's angle 29o (24o to 34o ) and a control group (B) of fifteen (8 females, 7 males) of healthy individuals were submitted in clinical examination and 3-D gait analysis. Direct linear transformation (DLT) was used for analysis of linear displacement on the three axes (x, y and z) as well...
