On the modeling crutch assisted locomotion: examining the interfaces with the g...
Sousa, Maria Francisca; Silva, Mariana Isabel Santos Rodrigues; Marques, Filipe; Silva, Miguel Tavares da; Flores, Paulo[Excerpt] Over the years, assistive devices for locomotion, such as crutches, have been developed to provide support to patients suffering from mobility and/or independence impairments [1]. According to the World Health Organization, more than a billion people worldwide depend on one or more assistive devices, and this number is estimated to double by 2050 [2]. Patients suffering from disabilities, such as spin...
Projeto integrador em engenharia mecânica
Flores, Paulo; Marques, Filipe; Silva, Mariana Isabel Santos Rodrigues; Novais, FranciscoEste livro aborda o ensino de projetos integradores no contexto da formação em Engenharia Mecânica, em que se dá particular destaque ao processo de teardown e ao estudo da dinâmica do carro. Após uma breve abordagem pedagógica aos projetos integradores, são apresentados os conceitos fundamentais relativos à metrologia dimensional e ao processo teardown. Subsequentemente, são detalhados os principais aspetos rel...
A new skeletal model for the ankle joint complex
Silva, Mariana Isabel Santos Rodrigues; Marques, Filipe; Miguel Tavares da Silva; Flores, PauloThe talocrural and the talocalcaneal articulations collectively form the ankle joint complex of the human foot and are the focus of investigation of this work. The talocrural articulation enables plantarflexion and dorsiflexion, while the talocalcaneal articulation allows inversion and eversion of the foot. A comprehensive analysis of the literature suggests that the ankle joint complex is modeled in different ...
A methodology to restrict the range of motion of joints: Application to the ank...
Silva, Mariana Isabel Santos Rodrigues; Marques, Filipe; Silva, Miguel Tavares da; Flores, PauloOne of the most critical aspects when developing biomechanical models is the formulation of the joints, which, in the case of the human body, have limited range of motion (RoM). Thus, restrictions to prevent joints from performing unacceptable movements and avoid unrealistic configurations of the adjacent bodies must be formulated. This study extends the authors’ previous work to demonstrate the potential of ap...
Experimental and computacional analisys of the human gait with crutches
Sousa, Maria Francisca; Silva, Mariana Isabel Santos Rodrigues; Marques, Filipe; Gonçalves, Sérgio B.; Silva, Miguel Tavares da; Flores, Paulo[Excerpt] 1. INTRODUCTION The use of mobility assistive devices, such as crutches, presentssignificant benefitsto disabled patients, as they not only promote independence, but also enable and enhance the participation in daily activities. However, the prolonged and repetitive use of such devices can be a source of secondary health problems, including shoulder and elbow tendinopathies [1]. The analysis of device...
A simple and comprehensive approach to formulate and solve problems in a non-tr...
Novais, Francisco; Silva, Mariana Isabel Santos Rodrigues; Gomes, Inês Varela; Puga, Hélder; Flores, Paulo[Excerpt] Learning and teaching dynamics is often considered by students and instructors to be a difficult and demanding subject, in the measure that it involves a good number of ingredients, chiefly those related to mechanics, physics, algebra, calculus, numerical methods and computational aspects [1]. This is particularly true when dealing with non-traditional courses. In this context, the present study is ca...
Modeling and analysis of the ankle joint complex with muscles
Silva, Mariana Isabel Santos Rodrigues; Sousa, Maria Francisca; Marques, Filipe; Gonçalves, Sérgio B.; Silva, Miguel Tavares da; Flores, Paulo[Excerpt] 1. INTRODUCTION The ankle joint complex of the human foot is composed of the talocrural and the talocalcaneal joints, and it is the focal point of this work. In general, plantarflexion and dorsiflexion are allowed by the talocrural joint, while the talocalcaneal joint permits inversion and eversion of the human foot. In this study, a spatial biomechanical multibody model of the ankle joint complex is ...
Multibody dynamics in robotics with focus on contact events
Silva, Mariana Isabel Santos Rodrigues; Coelho, Joana Sofia Falcato Pereira Lima; Gonçalves, Fernando; Novais, Francisco; Flores, PauloMultibody dynamics methodologies have been fundamental tools utilized to model and simulate robotic systems that experience contact conditions with the surrounding environment, such as in the case of feet and ground interactions. In addressing such problems, it is of paramount importance to accurately and efficiently handle the large body displacement associated with locomotion of robots, as well as the dynamic...
A comprehensive review on biomechanical modeling applied to device-assisted loc...
Silva, Mariana Isabel Santos Rodrigues; Marques, Filipe; Silva, Miguel Tavares da; Flores, PauloAccording to the World Health Organization, 15% of the world’s population lived with some form of disability in 2011 and, nowadays, more than one billion people worldwide require the use of one or more assistive devices (AD). The raising significance of this problem led several authors to develop biomechanical models capable of analyzing device-assisted locomotion. The scientific knowledge arising from this ana...
Modeling the ankle articular complex: a computational and experimental analysis
Silva, Mariana Isabel Santos Rodrigues; Marques, Filipe; Gonçalves, Sérgio; Silva, Miguel Tavares da; Flores, Paulo[Excerpt] The foot is a complex system that allows several movements of the daily life. Amongst its 31 anatomical articulations, the talocrural and the talocalcaneal ones, which collectively form the ankle articular complex of the human foot, are the focal point of this work. The axes of these articulations are non-coplanar, and the distance is defined as the height of the talus [1]. Literature review indicates...
