Resumo
É grande o número de mulheres que faz uso de sapatos com saltos na atualidade durante várias horas por dia, sendo freqüentemente sujeitas a andarem por diversos tipos de superfícies, sejam elas planas ou inclinadas, submetendo o sistema músculoesquelético a esforços variados. Os objetivos do presente estudo foram: adaptar uma esteira para realização de análise biomecânica; analisar a marcha de mulheres com uso de sapatos com saltos em comparação com a condição descalça; analisar a influência da inclinação da superfície sobre o padrão de marcha dos indivíduos e relacionar o efeito da utilização do calçado com salto com o efeito da inclinação da superfície. Uma esteira elétrica foi adaptada através da colocação de plataformas de força independentes para o pé direito e esquerdo, com o uso de 8 anéis e 32 extensômetros em localização estratégica.Um tripé e uma câmera fotográfica digital foram utilizados para a análise cinemática do joelho direito no plano sagital.Dez voluntárias jovens e saudáveis participaram do estudo, andando sobre a esteira descalças e com uso de sapatos com saltos de 5,0 cm, no plano horizontal, inclinado a 1,83° e 3,61°. Cada condição foi analisada durante 10 segundos, totalizando 60 segundos de análise de cada voluntária. A análise estatística não-paramétrica (teste de Wilcoxon) (p<0,10) demonstrou que o uso de sapatos com saltos com 5 cm de altura associado à marcha em plano horizontal e inclinado de 1,83° e 3,61° não altera o ângulo mínimo de flexão do joelho no plano sagital, porém exerce influência sobre o ângulo máximo do mesmo no plano horizontal, diminuindo-o com o uso do calçado. Foi constatado também que o uso do referido calçado apresenta relação com a velocidade da marcha de forma inversamente proporcional à inclinação da superfície, com exceção da inclinação de 3,61° com...
Actually it's large the number of women that make use of high-heeled shoes for several hours a day, often being subdued to gait different types of surfaces, smooth and/or inclined, subjecting the musculoskeletal system to a variety of efforts. The present study’s intentions were: to adapt a treadmill for the biomechanical analysis; to analyze women’s gait using high heels in comparison with the barefoot condition; to analyze the influence of a slope surface over the march pattern of individuals and to relate the effect of high-heeled shoes utilization with the effect of a slope surface. An electronic treadmill was adapted with the installation of independent force platforms for the right and the left foot, using 8 rings and 32 strain gages in a strategic location. These were connected trough 2 channels to the Spider 8, responsible for acquisition and processing the signals which, connected to a computer, allowed the data analysis by the Catman® 3.1 software. It was necessary the utilization of a gear motor for the high-heels gait’s velocity adaptation. A tripod and a digital camera were used for kinematic analysis of the right knee in the sagittal plane. For synchronization of kinematic and kinetic data, we used a light signaling that allowed the simultaneous start of data acquisition. Ten healthy young women volunteers participated on the study, walking on the treadmill barefoot and wearing shoes with heels of 5.0 cm on the horizontal plane, inclined 1.83 ° and 3.61 °. Each condition was analyzed for 10 seconds, summarizing 60 seconds of analysis of each volunteer. The images were fragmented in Quintic Player ® software and relayed to the software ImageJ ®, through which were analyzed the angular variation. Statistical analysis Non-parametric (Wilcoxon test) by using significance p <0.10 showed that the use of shoes with with 5 cm heels associated with motion...
