Shoulder musculoskeletal disorders affect half a millions of Canadians, especially manual workers and overhead athletes. Scientific evidence is limited for both prevention and rehabilitation of these disorders. My research program consists in combining biomechanical analyses and musculoskeletal computer simulations to better understand the pathology mechanisms. My team has already developed software to personalize arm immobilisation after a rotator cuff repair and a dynamic orthosis to hasten rehabilitation. My research program focuses on the development of computer models and devices to analyse the shoulder biomechanics with applications to prevention and rehabilitation of shoulder disorders.

First, our models will be improved to better estimate shoulder constraints during movements. Also we will design a clinical tool for shoulder diagnosis that may potentially become a reference diagnostic tool for shoulder.
Using such models and tools, innovative indicators of shoulder exposure to risk of shoulder injuries which will be tested on warehousemen and athletes in longitudinal studies. These indicators will help in establishing safer labor norms for reducing shoulder injuries.

Based on these models and tools, we will discriminate dangerous movements following a rotator cuff repair and then assess the benefit of our dynamic orthosis compared to commonly used orthoses using a clinical trial with 90 patients. Our recommendations will improve present clinical practices in order to hasten patients' rehabilitation.
