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

Today, the complex sensations of comfort (interaction body – clothing, suitability of fabrics, etc.) are subjectively evaluated on a static body. The goal of this project is to provide new knowledge about garment comfort and fit taking into account the body movement. The comfort sensation is objectively measured with new 3D simulation tools on animated bodies, returning numerical fitting data.

Thus, with this research, new avenues can be opened up for the development of innovative applications of advanced garment design. In particular, new pattern making methods taking into account the body movement can be imagined, an aspect that current processes are not able to consider nor apply in clothing.

A pilot project was carried out within the framework of this research, watch the video here.

Summary

Strengthening of shoulder muscles in rehabilitation protocols and sport practice can be achieved by a wide range of different exercises and several types of technique. In presence of a rotator cuff lesion, articular cartilage pathology or instability, recommendations for design of a shoulder strength training protocol aim at avoiding or minimizing subacromial impingement and stress on the articular cartilages or labrum. Very limited objective data is at disposable to emit such recommendations.

The goal of this study is to capture and simulate 30 to 50 rehabilitation exercises to study the impact on the glenohumeral joint (e.g. cartilage’s compression, incidence of subacromial impingement) and rotator cuff (e.g. tendon lengthening of the subscapularis, supraspinatus, infraspinatus and teres minor). Ultimately, this study will better target rehabilitation exercises of the shoulder.

Summary

The shoulder has the widest range of motion of any joint in the body, but at the cost of inherent instability causing pain and functional disability. To better understand the mechanisms involved in shoulder stability, an in-depth analysis of the shoulder kinematics is instrumental. Therefore, the project aims at developing a new kinematic model to reliably evaluate the three-dimensional motion of the shoulder based on motion capture. To set up and evaluate the kinematic model, a clinical study involving tennis players is performed.

The expected results could open up new possibilities to orthopedic surgeons in order to improve assessment and treatment of patients with shoulder functional abnormalities.
