In-shoe plantar pressures and ground reaction forces during overweight adults' ...
Castro, Marcelo Peduzzi; Abreu, Sofia; Sousa, Helena; Machado, Leandro; Santos, Rubim; Vilas Boas, JoãoPurpose: Because walking is highly recommended for prevention and treatment of obesity and some of its biomechanical aspects are not clearly understood for overweight people, we compared the absolute and normalized ground reaction forces (GRF), plantar pressures, and temporal parameters of normal-weight and overweight participants during overground walking. Method: A force plate and an in-shoe pressure system w...
Anticipatory postural adjustments during sitting reach movement in post-stroke ...
Pereira, Soraia; Silva, Cláudia; Ferreira, Sílvia; Silva, Cláudia; Oliveira, Nuno; Santos, Rubim; Vilas Boas, João; Correia, Miguel V.The study assessed the effect of velocity of arm movement on the generation of APAs in the contralateral and ipsilateral muscles of individuals with stroke in the sitting position. In the sitting position, 10 healthy and 8 post-stroke subjects reached for an object placed at the scapular plane and mid-sternum height at self-selected and fast velocities. Electromyography was recorded from the anterior deltoid (A...
Ground reaction forces and plantar pressure distribution during occasional load...
Castro, Marcelo Peduzzi; Abreu, Sofia; Sousa, Helena; Machado, Leandro; Santos, Rubim; Vilas Boas, JoãoThis study compared the ground reaction forces (GRF) and plantar pressures between unloaded and occasional loaded gait. The GRF and plantar pressures of 60 participants were recorded during unloaded gait and occasional loaded gait (wearing a backpack that raised their body mass index to 30); this load criterion was adopted because is considered potentially harmful in permanent loaded gait (obese people). The re...
Alterações no recrutamento dos músculos abdominais na dor lombopélvica
Carvalho, Paulo; Moreira, Camilo; Santos, Rubim; Vilas Boas, JoãoObjectivo: Verificar se existem alterações no padrão de recrutamento do transverso do abdómen/oblíquo interno, recto abdominal e oblíquo externo em indivíduos com história de dor lombopélvica aguda. Métodos: Foi realizado um estudo do tipo observacional, analítico e transversal, cuja amostra consistia num grupo de 15 indivíduos que nunca tiveram dor lombopélvica e por outro de 14 indivíduos do sexo feminino que...
Force and pressure analysis during occasional loaded gait
Castro, Marcelo Peduzzi; Santos, Rubim; Abreu, Sofia; Sousa, Helena; Machado, Leandro; Vilas Boas, JoãoThe aim of this study was to compare the ground reaction forces and plantar pressure parameters between unloaded and occasional loaded gait. The ground reaction forces and plantar pressure of 60 participants were recorded during unloaded and occasional loaded gait (wearing a backpack which raises the participant´s body mass index to 30). The results indicate an overall increase of forces and plantar pressure du...
Caracterização biomecânica do gesto de alcançar em individuos pós Acidente Vasc...
Silva, Cláudia C.; Correia, Miguel V.; Vilas Boas, João; Santos, RubimÉ objectivo deste trabalho caracterizar biomecanicamente o gesto de alcançar em indivíduos pós Acidente Vascular Encefálico. A amostra é constituída por 4 indivíduos sem patologia do foro neuro-músculo-esquelético e 4 indivíduos com confirmação imagiológica do diagnóstico de AVE único e unilateral no território da artéria cerebral média, há pelo menos 3 meses; ausência de neglet; ausência de alterações visuais,...
EMG of the transverse abdominus and multifidus during pilates exercises
Carvalho, Paulo; Pereira, Ana; Santos, Rubim; Vilas Boas, JoãoThe purpose of this research study was to evaluate the intensity of muscle activation of Transverse Abdominus /Oblique Internal (TrA/OI) and Multifidus (Mu) during the performance of four Pilates exercises (and variations), compared, in order to understand the importance of these exercises in the lumbopelvic stability in healthy subjects. The sample consisted of 8 individuals. Using the surface electromyography...
The influence of differente speeds on backpacker's gait kinectics
Castro, Marcelo Peduzzi; Abreu, Sofia; Sousa, Helena; Figueiredo, Cristina; Machado, Leandro; Santos, Rubim; Vilas Boas, JoãoThis study analyzed the influence of different speeds on ground reaction force’s (GRF), impulses and mean vertical force during gait of people submitted to occasional overload (backpack). A force plate was used to record the GRF data of 60 young adult subjects walking in two different cadences: 69 steps/min (slow gait) and 120 steps/min (fast gait). During the slow gait, the impact and propulsive impulses of ve...
Caracterização cinética e cinemática da marcha de indivíduos adultos obesos
Sousa, Helena; Santos, Rubim; Vilas Boas, João; Vaz, M.; Abreu, Sofia; Castro, Marcelo PeduzziO presente estudo apresenta a caracterização cinemática e cinética da marcha de indivíduos obesos. Envolveu instrumentos como Pedar-Novel, para recolha de dados da pressão plantar; Plataforma Bertec 4060-10, para dados de Força de Reacção ao Solo (FRS), Câmaras digitais Sony, 50Hz para ângulos do pé; IPAQ para dados de actividade física. Foram seleccionados individuos com IMC≥30Kg/m2, para o grupo experimental ...
Comparative analysis of the ground reaction forces, during the support phase, i...
Santos, Rubim; Gil, Belandina; Marques, Alda; Vilas Boas, João; Silva, JoséTo analyze and compare the Ground Reaction Forces (GRF), during the stance phase of walking in pregnant women in the 3rd trimester of pregnancy, and non pregnant women. 20 women, 10 pregnant and 10 non pregnant, voluntarily took part in this study. GRF were measured (1000 Hz) using a force platform (BERTEC 4060-15), an amplifier (BERTEC AM 6300) and an analogical-digital converter of 16 Bits (Biopac). The study...
