Characterization of lower-limbs inter-segment coordination during the take-off extension in ski jumping

Kamiar Aminian, Julien Favre, Julien Chardonnens

Take-off, the most important phase in ski jumping, has been primarily studied in terms of spatio-temporal parameters, with little known about its motor control aspects. This study aims to assess the inter-segment coordination of the shank-thigh and thigh-s ...

Cement distribution in vertebroplasties: imaging and simulation

Vincent Stadelmann

Prophylactic vertebroplasty, the percutaneous injection of bone cement into a weak vertebral body (VB), has been shown to reinforce the bone and possibly to minimize fracture risks. Cement leakage is still a common occurrence that can cause severe complica ...

Buckling-induced encapsulation of structured elastic shells under pressure

Pedro Miguel Nunes Pereira de Almeida Reis

We introduce a class of continuum shell structures, the Buckliball, which undergoes a structural transformation induced by buckling under pressure loading. The geometry of the Buckliball comprises a spherical shell patterned with a regular array of circula ...

Analysis of inter-segment coordination during the take-off of ski jumping

Kamiar Aminian, Julien Favre, Julien Chardonnens

In ski jumping, take-off (TO) is considered as the most important phase. While spatio-temporal features have been identified during this phase, inter-segment coordination has never been investigated. This study proposed a new method using body worn inertia ...

Penetration Depth Method-Novel Real-Time Strategy for Evaluating Femoroacetabular Impingement

Daniel Thalmann, Ronan Boulic, Ehsan Arbabi

We introduce a new method for computerized real-time evaluation of femoroacetabular impingement (FM). In contrast to previously presented stress analyses, this method is based on two types of predictions of penetration depths for two rotating bodies: curvi ...

Total shoulder arthroplasty: Downward inclination of the glenoid component to balance supraspinatus deficiency

Dominique Pioletti, Alexandre Terrier, Alain Farron, Francesco Merlini

Hypothesis: Supraspinatus deficiency associated with total shoulder arthroplasty (TSA) provokes eccentric loading and may induce loosening of the glenoid component. A downward inclination of the glenoid component has been proposed to balance supraspinatus ...

Fast collision detection methods for joint surfaces

Daniel Thalmann, Ronan Boulic, Ehsan Arbabi

In the recent years medical diagnosis and surgery planning often require the precise evaluation of joint movements. This has led to exploit reconstructed three-dimensional models of the joint tissues obtained from CT or MR Images (for bones, cartilages, et ...

Contact modeling and collision detection in human joints

Ehsan Arbabi

Collision detection among virtual objects is one of the main concerns in virtual reality and computer graphics. Usually the methods developed for collision detection are for either very general cases or very specific applications. The first main goal of th ...

Pelvic motion measurement during over ground walking, analysis and implementation on the WalkTrainer reeducation device

Reymond Clavel, Mohamed Bouri, Yves Stauffer, Patrick Métrailler, Jacques Fournier, Yves Allemand

Pelvic motions are of great importance while walking, and have thus to be taken into account when developing and controlling rehabilitation devices. This paper will first introduce a new reeducation devices for paraplegic people: the WalkTrainer. This devi ...
