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…

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…

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…

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…

Standard laparoscopy is responsible for musculoskeletal problems because of surgeons anti-ergonomic positions. Robot-assisted laparoscopy seems to reduce these musculoskeletal disorders because of the surgeons seated position. The…

Movement variability is an essential characteristic of human movement. However, despite its prevalence, it is almost completely ignored in workstation design. Neglecting this variability can lead to skip over parts of the future operator’s…

Increasing age of workers should be taking into account in the work station conception. It is known that functional capacities and muscle properties physiologically change with ageing. This experiment wanted to investigate motor adaptation…

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…
