Outline of reasons and objectives
Working under time constraints is particularly difficult for ageing workers. “Leeway” or “room for manoeuvre” may enable regulation strategies to be put in place or production contingencies to be coped with more…

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…

Time constraints can be particularly stressful for older workers in repetitive work. Opportunities for work rate regulation could offer a way of dealing with production variations. The aim of this laboratory study was to investigate the effects…

Repetitive work at required pace, as observed on assembly lines, is often characterized by reduced amounts of temporal margin of maneuver (TMM). Various epidemiological studies have shown that working under time constraints is particularly…

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…

Optical Motion Capture Systems (OMCS) are considered the gold standard for kinematic measurement of human movements. However, in situations such as measuring hand kinematics during a hairdressing activity, markers can be obscured, resulting…

Skill acquisition is traditionally assessed based on productivity measures, such as Movement Time (MT), which reflect task execution speed. However, movement smoothness may provide additional insights into skill progression by assessing improvements…

For ergonomical, purpose, we looked at posture and vertical force applied on a workstation when doing a standing repetitive assembly task at different rhythm and as a matter of age. These two factors seem to increase the vertical force used to make…

Test methods that use pushing forces to evaluate the maximal load capacities of carts in design standards require a flat, smooth and horizontal steel plate, and thus didn t take into account the real conditions of work. Resistive forces of a single…
