Proposed research:
Definition and comparison of musculoskeletal disorder (MSD) risk based on motion analyses of common working activities
/ Définition et analyse comparative d'un indice de troubles musculosquelettiques (TMS) reliés à l'analyse de mouvement lors d'activités de travail de la vie quotidienne.

Objectives
This research assistantship will be awarded to a student studying in the Master's of Applied Science (M.Sc.A.) programme of the Faculté d'ingénierie, Université de Moncton (courses in French) focusing in the field of ergonomics and MSD prevention using biomechanical modelling. The research assistant will use the relationship between motion-based task efficacy measures and indices of risk of developing upper limb MSDs to compare a population at greater risk (upper limb prosthesis users) with a general working age population. The result of this comparison will help formulate suggestions for changes to work environments and tools (including prosthesis design) to minimise MSD risk.

Requirements
Applicants should possess an undergraduate degree in engineering (industrial, systems or mechanical), ergonomics or kinesiology related field. Competence in French and English is required, French being the language of study at Université de Moncton, and the VICON system used for recordings being located at the English-language Institute of Biomedical Engineering at University of New Brunswick, Fredericton.

Funding:
$15000 per year CDN funding is available for a master's level graduate student working on this research while studying for two years. Additional funding through a teaching assistantship is possible.

Summary of the proposed research program:
This research will investigate the relationship between motion-based task efficacy measures and the risk of developing musculoskeletal disorders (MSDs) of the human upper limbs comparing an upper limb prosthesis users population with a general adult population. Task efficacy is defined as goal-oriented effectiveness, and to date has been based on composite segmental mechanical energy, calculated over the duration of a given goal-oriented task (Black 2001). Since adult upper limb prosthesis users are three times more likely than the general working population to develop pain associated with MSDs (Jones and Davidson 2001; Stocker and Neufeld 2001; Muggleton et al. 1999), this population comparison is particularly relevant.

Using an 8-camera VICON MCAM system, simultaneous motions of markers on both arms will allow detailed modelling of upper limb movements and efficacy variations between upper limb prosthesis users and non-users during common tasks to help reduce the risk of developing MSDs.

Sommaire de la recherche proposée :
On enquête le lien entre les moyens de mesure d'efficience basés de mouvements et le risque de développer des troubles musculosquelettiques (TMS) des membres supérieurs humains. On anticipe comparer une population générale d'adulte à d'autres à risque plus élevé, comme les amputés utilisant une prothèse à bras. Ces amputés souffrent de douleurs typiques des TMS trois fois plus souvent que la population générale (Jones et Davidson 2001; Stocker et Neufeld 2001; Muggleton et al. 1999).

L'efficience de tâche est l'efficacité d'arriver à un but prédéfini et elle a été associée à une mesure de l'énergie mécanique par segment de membre supérieur, ceci calculée sur la durée totale de la tâche (Black 2001). La déviation angulaire du bras de sa position neutre est associée à un risque accru de TMS, et montre du potentiel comme mesure simple (Black et al. 2005). En se servant d'un système VICON MCAM à 8 caméras, on est en mesure de capter les détails requis pour calculer l'efficience des deux bras simultanément. L'identification et la quantification des distinctions entre méthodes, mouvements et l'efficience associée aux individus à prothèse et ceux sans prothèse est une étape critique pour cibler la réduction des TMS chez les amputés.
