Knowledge of ergonomics/human factors plays an important role in the creation and design of safety shoes and insoles, contributing to worker protection, comfort, and stability. The purpose of this study is to compare previous insole designs and analyze the plantar pressure and gait pattern kinematics using the Oxford foot model protocol. The tests were performed comparing the environments on the three rockers o...
Background and aims – The muscular co-contraction of the quadriceps, hamstrings, and hip external rotators presents a crucial role in the dynamic control of joint stability, and so does specifically the frontal plane knee valgus mechanism. The purpose of this study was to describe the relationship between muscle activation and the frontal plane knee angle variation during the vertical jump stance phase. Methods...
Introduction – Futsal is a demanding sport, so the application of Kinesio tape bands emerges as an intervention hypothesis to take into consideration. Objectives – To analyze Kinesio tape effects on the muscular range and activation of the peroneal muscle and tibialis anterior muscle during the execution of a pass. Methodology – For each specified situation (without and with Kinesio tape band for the tibialis a...
Physiological perfusion asymmetries in the lower limb are known, although poorly understood, as are asymmetries reported in plantar pressure and stance. This preliminary study aims to explore potential relationships between perfusion and pressure variables in humans. A convenience sample of eight healthy individuals (25.25 ± 5.37 years old) of both sexes, was selected. Chosen variables were perfusion, plantar p...
Aims: Dynamic joint stiffness (DJS) is used as a joint stability indicator. The objective of the present study is to verify the influence of footedness in ankle joint stability during the gait stance phase. Study Design: Comparative study. Place and Duration of Study: MovLab/ CICANT/ Universidade Lusófona de Humanidades e Tecnologias, between November 2013 and June 2014 Methodology: 31 subjects (20 female and 1...
Objetivo: A avaliação do perfil de lateralidade, medida composta pela avaliação de quatro índices de dominância que incluem a da mão, do pé, visual e auditiva, é amplamente utilizada em várias áreas do conhecimento. O Lateral Preference Inventory (LPI) é um instrumento simples que permite esta avaliação. O objetivo deste estudo é o de traduzir e adaptar culturalmente o LPI para a língua portuguesa, bem como tes...
Introdução – O futsal é um desporto exigente, pelo que a aplicação de bandas de kinesio tape surge como uma vertente de intervenção a considerar. Objetivos – Analisar o efeito do kinesio tape na ativação e amplitude muscular do longo peroneal e tibial anterior na execução de um passe. Metodologia – Foram estudados 40 passes por cada situação definida (sem banda de kinesio tape e com banda para o tibial anterior...
Introdução e objetivos – A contração muscular do quadricípete, isquiotibiais e rotadores externos apresenta um papel crucial no controlo da estabilidade articular dinâmica, nomeadamente no valgo de joelho no plano frontal. O objetivo deste estudo foi descrever a existência de relação entre a ativação muscular (medida pela recolha eletromiográfica do reto anterior, dos isquiotibiais e do grande glúteo) e a varia...
