Summary

Reverse Shoulder Prosthesis Simulation investigates how different implant and anatomical parameters affect shoulder range of motion after reverse shoulder arthroplasty (RSA).

The study focuses in particular on glenoid lateralization, humeral inclination and critical shoulder angle (CSA), using computer-assisted simulations to evaluate their influence on joint mechanics and the risk of impingement or instability.

The objective is to identify surgical parameters that can help optimize implant configuration and reduce the risk of articular conflict and dislocation.

Within the project, Artanim was responsible for the dynamic simulation of reverse shoulder prostheses using kinematic data.

Summary

3D Proto investigates how virtual 3D prototyping can improve the design, fit and performance of technical sportswear. Detailed simulations provide quantitative information on how garments interact with the body, including areas of compression and deformation that are difficult to assess using conventional static prototypes.

The project focuses on improving garment prototyping workflows for the active sportswear sector by characterizing the physical and mechanical properties of technical fabrics and combining them with animated 3D body models. This allows sports garments to be simulated and evaluated under realistic movement conditions.

Within 3D Proto, Artanim provided realistic body animations for alpine skiing, Nordic skiing, running and hiking. Artanim also developed software tools to support fabric measurement protocols through the analysis of body motion and deformation.

Summary

Motion and Unconsciousness investigates how people coordinate their bodies during joint action and social interaction. The project focuses on the relationship between self and other representations, shared action and the behavioral mechanisms that contribute to the feeling of acting together.

Motion capture was used to record pairs of participants performing joint-action and social-interaction tasks, allowing quantitative analysis of body posture, motor coordination, synchronization and nonverbal behavior.

These behavioral measurements were combined with respiratory coupling and dual electroencephalography (EEG) to investigate the bodily and neural mechanisms associated with interpersonal coordination and synchrony.

Summary

ArthroPlanner aimed to develop patient-specific surgical planning tools that combine 3D anatomy with functional joint kinematics. Building on Artanim’s previous research in medical imaging, motion capture and biomechanical simulation, the project explored how dynamic information could complement conventional static anatomical planning and support more personalized clinical decision-making.

A major application focused on shoulder surgery and the development of a computer-assisted planning solution for acromioplasty. Patient-specific 3D anatomical models and joint simulations were used to identify areas of subacromial impingement and estimate the bone resection required during surgery. This approach was subsequently evaluated through clinical studies comparing planned and actual resections as well as guided and conventional freehand acromioplasty.

A similar planning solution was developed for femoroacetabular impingement (FAI) of the hip. Patient-specific 3D models and joint simulations were used to identify impingement zones during movement and to support planning of the bone resection required to restore functional range of motion. Unlike the acromioplasty application, this hip planning solution was not clinically evaluated.

The project also extended these patient-specific modeling techniques to the knee. Motion capture, magnetic resonance imaging and biomechanical optimization were combined to improve the estimation of knee kinematics at high flexion angles and to analyze structures such as the posterior cruciate ligament during static and dynamic movements.

More broadly, ArthroPlanner contributed to Artanim’s research toward dynamic surgical planning solutions for the hip, shoulder and knee, integrating patient-specific anatomy and movement into clinically relevant 3D tools.

Summary

Anterior shoulder instability is a common condition in young and athletic adults and can lead to recurrent dislocations or subluxations. When instability becomes recurrent, surgical treatment may be required. Beyond preventing further dislocation, an important question is whether surgery also restores normal shoulder mechanics and joint stability during movement.

This study investigated shoulder kinematics in patients with anterior instability using dynamic motion capture before and after surgical treatment. By comparing joint motion pre- and post-operatively, the project aimed to better characterize the biomechanical effects of instability and assess how surgical treatment influences shoulder stability and movement.
