In all human movements, in particular those related to work activities, variability is observed. Even for a repetitive task, trajectories, muscular activities, or exerted forces are never identical, both for different people and for the same person…

Outline of reasons and objectives
The computer is in common use at work. In 2010, in France, 52% of workers used a computer at work and 23% of them remained in front of a screen for 20 hours or more per week. If the computer is in common use, then so is the mouse…

Movement variability is often neglected when analysing work situations. It is also practically ignored when designing work situations, designers being focused on the aim of defining standard procedures that minimize production cycle times…

Movement variability is an essential characteristic of human movement: the same motor task is never performed in exactly the same way twice. This variability is related to the numerous redundancies in the human locomotor system, and depends…

This study simultaneously compared four working postures (sitting on an office chair, on a ball, standing and pedaling on an ergocycle) and five pointing device configurations (traditional and slanted mouse placed next to and in front of the keyboard…

Background and Objectives The most commonly observed working posture among computer-based employees is sitting on an office chair. If prolonged, this posture leads to sedentary behavior, which is harmful to health. In order to limit exposure…

Digital humans are software tools used for work equipment design. They can simulate the future workers’ activity and assess the workplace ergonomics. They therefore offer genuine advantages when prevention (safety and health) is to be integrated…

This study compared muscular and postural stresses, performance and user preference when using a standard mouse and two vertical mice - one with a 35 angle and the other with a 65 angle to the horizontal - placed in 3 different positions on the desktop…

Our study compared muscular activity and resultant external force measurements during a clip fitting activity. Clips were inserted with two methods: with bare hands and with a pneumatic tool. Measurements were compared with the thresholds…

Within the framework of its missions of assistance for the prevention of WRMSD of the Upper Limb, the INRS was requested to study the possible relation between the use of two-hand control devices and the development of WRMSD. This request came…
