Dynamic simulation of RSA

Start date:
January 2017

End date:
December 2017

Funding:
Hirslanden Clinique La Colline

Coordinator:
Artanim

Summary

The goal of this project is to simulate reverse shoulder prostheses (RSA) to evaluate the variability of several biomechanical factors and the impact on the range of motion. In particular, we are interested in evaluating the effect of glenoid lateralization, humeral inclination and critical shoulder angle (CSA). These computer-assisted simulations will provide operating parameters which aim to minimize the onset of articular conflicts and luxations.

In this project, Artanim is responsible for dynamically simulating reverse shoulder prostheses from kinematic data.

Coordinator:
Geneva University of Art and Design (HEAD)

Summary

A sample model on a higher technological level, such as a precise virtual 3D prototype, contains innovative numerical fitting information (e.g., data about the areas of compression of a garment) that could improve the design and quality of the final sports garment and better satisfy the customer.

The aim of this research project is thus to reform existing garment prototyping processes for the active sportswear sector. The main focus is on the definition of accurate physical and mechanical high-tech sports fabric properties and on the use of virtual sports body animations to perform accurate simulation of sports garments.

In this project, Artanim is in charge of providing realistic body animations of different sports (alpine skiing, Nordic skiing, running and hiking). Moreover, Artanim works on the development of software tools to improve the fabric measurements protocol by analyzing body motion and deformation.

Summary

Social interaction generally involves a multi-layered interaction where there is an interplay of self and other representations together with a participatory factor where people feel “they do things together”. Descriptions of this interaction range from high-level intentional descriptions on shared representations down to precise motor, gestural and postural studies on behavioral coordination.

In this project, we use motion capture in order to record and study specific motor factors of two people when they engage in joint action tasks and/or in social interaction. It is hence possible to obtain quantitative measurements at the behavioral level (body posture, motor coordination and synchronization, nonverbal language, etc.) in order to explore the brain and bodily mechanisms that relate to it. Respiration coupling and dual electroencephalography are also performed in this project.

Coordinator:
Artanim

Summary

The goal of this project is to develop several surgical planning tools taking into account both the anatomy and kinematics of the patient’s joint. We intend to continue and extend our previous research works by integrating them into a 3D surgical planning solution, called ArthroPlanner, which could be used in clinical routine and could thus directly benefit patients.

This project mainly aims at developing solutions for the dynamic planning of the hip and shoulder and to extend our work to the knee.

Dynamic evaluation of instability

Coordinator:

Summary

Shoulder instability is a common pathology in young or athletic adult that results in chronic dislocations or subluxations. When multiple dislocations episodes occur, surgical treatment is indicated. But this treatment really stabilizes the joint or only prevents it to dislocate?

The objective of this study is to investigate and compare the shoulder stability in patients with anterior instability by performing a dynamic motion capture analysis before and after surgical treatment. The results of this study will provide a better understanding of this disease, and evaluate the effectiveness of the proposed surgical treatment.
