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 was 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 provided a better understanding of this disease, and evaluated the effectiveness of the proposed surgical treatment.

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 was to provide new knowledge about garment comfort and fit taking into account the body movement. The comfort sensation was 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

The goal of this project was to develop a solution that aimed at creating a full body avatar of the user by merging head and body scans from different scanning technologies. The first task of this project was to investigate and prototype a solution that provided good quality textured head scans using an affordable multi-cameras system. Capturing the head with sufficiently high fidelity is of great importance to provide a convincingly realistic representation of the user.

The second task was to merge the results of the head scanning with body scan data using template fitting. This process allows easy extraction of body measurements for further usage and automatic generation of an internal skeleton for animation.

Summary

Thoracic outlet syndrome (TOS) is a rare condition that involves pain in the neck and shoulder, numbness and tingling of the fingers. It happens when the nerves or blood vessels are compressed in the thoracic outlet which is the area between the rib cage and clavicle.

The goal of this study was to better understand certain causes of TOS by performing a dynamic simulation of the shoulder complex. Repetitive arm and shoulder movements, as well as anatomical defects can play a role in the development of TOS. In this study, motion capture and medical imaging (CT, MRI) were combined to improve assessment of this condition in symptomatic patients.

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 was 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.
