Méthodologie interdisciplinaire de prévention des TMS : association de la Biomécanique et de la Clinique de l’activité

Abstract

In both France and abroad, musculoskeletal disorders (MSD) remain the most widespread occupational diseases. The scientific literature has established that links exist between the occurrence of MSD and the professional gesture. The aim of this paper is to show how biomechanical analysis helps to create intervention tools implemented in a methodological framework in clinical activity with a view to preventing MSD through analysis of the gesture. The aim of this paper is to analyse how an intervention was conducted within the general methodological framework of occupational psychology using activity-clinic research based on professional gesture analysis and it also benefited from interdisciplinary co-operation with biomechanics. The interdisciplinary methodology employed in relation to eight gravediggers consisted of different steps that included a detailed analysis of the muscular activity of the shoulder and back muscles. The results show that the interdisciplinary methodology makes it possible to widen the potential development zone of the gesture in the gravediggers’ activity by stimulating their professional discussions. The creation of visibility and discussion in the profession of inter- and intra-individual variability has opened up the professional world to new forms of action to prevent MSD.
