Análise computadorizada da marcha de adultos jovens saudáveis

Abstract

Ethnics and cultural differences can have influence in the gait parameters. These can also be influenced by the gender, the corporal dimensions and the condition of health or illness. The aim of this work was to verify if exist significant differences in the gait patterns of healthful young men and women. Thus, was realized a retrospective study with analysis of secondary data of the data base of the Movement Laboratory of Goiás State University, equipped with computerized three-dimensional system of gait analysis. The gait data of nine men and nine women with age averages of 26,33 years and 25,33 years respecttively had been evaluated. The results had shown that the evaluated women are lower and lighter than men, presenting high values of not normalized cadence and speed, and normalized cadence, step lengths and speed (p = 0,05). They also had significant differences in the kinematics of the sagittal plan, with the women presenting higher peak value of hip extension at the end of the stance, greater amplitude of knee flexion during stance and swing phases, and minor amplitude of the first ankle-foot complex rocker (p = 0,05). It can be concluded that the studied sample presented significant differences (intergenders) in several of the evaluated parameters of gait. It is assumed that these differences can be related to the anatomical variations of men and women and to the cultural habits.
