A methodology to restrict the range of motion of joints: Application to the ank...
Silva, Mariana Rodrigues da; 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...
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...
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...
A compendium of contact force models inspired by Hunt and Crossley’s cornerston...
Silva, Mariana Isabel Santos Rodrigues; Marques, Filipe; Silva, Miguel Tavares da; Flores, PauloThe selection of the contact force model plays a crucial role in the modeling and analysis of dynamical systems. The seminal work by Hunt and Crossley, published in 1975, is one of the most prominent contact force models that finds application in different areas of science and engineering. The contact force approach proposed by Hunt and Crossley has motivated and inspired a large number of researchers that, eve...
On the modeling of biomechanical systems for human movement analysis: a narrati...
Roupa, Ivo; Silva, Mariana Isabel Santos Rodrigues; Marques, Filipe; Gonçalves, Sérgio B.; Flores, Paulo; Silva, Miguel Tavares daThe rising importance of movement analysis led to the development of more complex biomechanical models to describe in detail the human motion patterns. The models scaled from simplistic two-dimensional to three-dimensional representations of body including detailed joint, muscle, tendon, and ligament models. Different computational methodologies have been proposed to extend traditional kinematic and dynamic ana...
A novel methodology to restrict the range of motion of human articulations
Silva, Mariana Isabel Santos Rodrigues; Marques, Filipe; Silva, Miguel Tavares da; Flores, PauloThe human movement has long been a subject of extensive investigation by many authors, involving a vast interest in both clinical and sports applications. The use of biomechanical models of the human body can greatly contribute to the advancement of the body of knowledge in this scientific field as they provide rigorous information on several key biomechanical parameters. Thus, the modeling of human articulatio...
Current evidence on biomechanical modeling for the analysis of crutch-assisted ...
Silva, Mariana Isabel Santos Rodrigues; Marques, Filipe; Silva, Miguel Tavares da; Flores, PauloCrutches are utilized as a mean of locomotion by patients with a variety of long-term disabilities, such as cerebral palsy or spinal cord injury. These assistive devices help reducing the load imposed on the injured lower extremities, while allowing an upright posture. However, crutch-assisted gait places a considerable repetitive effort on the upper extremities (UE), which are not adapted to weight-bearing tas...
A comparison of spherical joint models in the dynamic analysis of rigid mechani...
Silva, Mariana Rodrigues da; Marques, Filipe; Silva, Miguel Tavares da; Flores, PauloSpherical joints, usually known as ball and socket joints, are utilized in several engineering applications. On the one hand, these types of joints may be found in mechanical systems acting as a pivot element between the wheels and the suspension in cars. On the other hand, ball and socket joints can also be used to model human articulations, as in the case of the hip and shoulder. From more simplistic to more ...
A review on foot-ground contact modeling strategies for human motion analysis
Saraiva, Leonor; Silva, Mariana Isabel Santos Rodrigues; Marques, Filipe; Silva, Miguel Tavares da; Flores, PauloThis review discusses the methodologies available in the literature, usually utilized to study the foot-ground interaction in the human locomotion. For this purpose, PubMed, Web of Science and Scopus databases were considered to identify publications focusing on foot-ground contact modeling strategies. As the consequence of a critical reading of those publications, some additional papers were identified and inc...
Current perspectives on the modeling of the foot-ground interaction for human m...
Saraiva, Maria Leonor de Barros; Silva, Mariana Isabel Santos Rodrigues; Marques, Filipe; Silva, Miguel Tavares da; Flores, PauloContact-impact events are multifaceted phenomena because their modeling process strongly depends on multiple factors, such as the geometry of the contacting surfaces, the local physical properties of the materials, and the numerical representation of the interaction between the contacting bodies. In particular, when the geometric and material properties are of complex nature, it is still a quite challenging pro...
