A Comparison Between Joint Coordinate System and Attitude Vector for Multi-segment foot Kinematics

Kamiar Aminian, Julien Favre, Xavier Crevoisier, Hossein Rouhani

The joint angles of multi-segment foot models have been primarily described using two mathematical methods: the joint coordinate system and the attitude vector. This study aimed to determine whether the angles obtained through these two descriptors are com ...

Comparing localized and nonlocalized dynamic 31P magnetic resonance spectroscopy in exercising muscle at 7T

Christine Nabuurs

By improving spatial and anatomical specificity, localized spectroscopy can enhance the power and accuracy of the quantitative analysis of cellular metabolism and bioenergetics. Localized and nonlocalized dynamic 31P magnetic resonance spectroscopy using a ...

Simulation of total ankle replacement using numerical modeling

Sara Molins Cabaní

The ankle is a complex joint of the human body which is most often affected by trauma. Osteoarthritis is a joint disease that can require surgical intervention and when it affects the ankle there are two options to achieve pain relief. For years ankle fusi ...

Model-Based Estimation of Knee Stiffness

Serge Pfeifer

During natural locomotion, the stiffness of the human knee is modulated continuously and subconsciously according to the demands of activity and terrain. Given modern actuator technology, powered transfemoral prostheses could theoretically provide a simila ...

Development of patient-specific numerical musculoskeletal model to assess patellar resurfacing

Francesc Levrero Florencio

Osteoarthritis is the most common joint disease, with the knee being the most commonly affected joint. It is usually found in elder population, affecting more than a third of the people aged over 65 years old. Total knee arthroplasty (TKA) is the most sati ...

Distribution of muscular forces in a numerical musculoskeletal model of the shoulder

Valérie Hélène Emilie Malfroy Camine

The shoulder is a complex joint with many muscles acting between the scapula and the humerus. Thus it is obvious that the mechanical system is indeterminate and an optimization method has to be used to find the muscular forces acting on the glenohumeral jo ...

Plasticization of polylactide foams for tissue engineering

Pierre-Etienne Bourban, John Christopher Plummer, Matthieu Cuénoud

Supercritical CO2 foaming of amorphous and semicrystalline polylactides plasticized by blending with 20 wt% polyethylene glycol has been investigated as a means of producing low-stiffness bioresorbable scaffolds for tissue engineering. For a given set of f ...

Oscillator-based assistance of cyclical movements: model-based and model-free approaches

Auke Ijspeert, Jesse van den Kieboom, Renaud Ronsse

In this article, we propose a new method for providing assistance during cyclical movements. This method is trajectory-free, in the sense that it provides user assistance irrespective of the performed movement, and requires no other sensing than the assist ...

Anchoring the SLIP template: The effect of leg mass on running stability

Auke Ijspeert, Soha Pouya, Rico Möckel

Spring-like leg behavior was found in the global dynamics of human and animal running in sagittal plane. The corresponding template model, the conservative spring-loaded inverted pendulum (SLIP), shows stability for a large range of speeds and is, therefor ...

Neuromuscular Modeling and Visualization of the Human Lower Extremities

Anders Sandholm

Today the field of neuromuscular simulations is widely used to understand the underlying dynamics of the movement of living beings, from gait research, treatment of patient with gait problems, to the teaching of physicians and the development of ergonomic ...
