Unlabelled: Prolonged repetitive lifting is a whole-body exertion. Despite this, the roles and physical exposures of the upper extremities are frequently neglected. The influence of precision requirements and cognitive distractions on upper extremity responses when lifting was evaluated by quantifying several biomechanical upper extremity quantiti...

Anthropometric studies typically require a large number of individuals that are selected in a manner so that demographic characteristics that impact body size and function are proportionally representative of a user population. This sampling approach does not allow for an efficient characterization of the distribution of body sizes and functions of...

Several observational methods are available for ergonomists to evaluate the exposure to musculoskeletal disorder (MSD) risk factors associated with work. Those methods can be used to evaluate the impact of modifications done at a workstation on the exposure to risk factors. Three methods (QEC, OCRA and 4D Watbak) were used to assess the exposure to...

Wheeled mobility device users face challenges in terms of access to the built environment and maneuverability within the built environment has received limited attention. As the wheeled mobility device user population has changed drastically in the recent years, there is a need to update accessibility standards and develop reliable methods for test...

Different sources can lead to modifications at a workstation such as external (out of control of the company) and internal (intended by the company) sources. Modifications from both source types could potentially influence the level of exposure of employees to different risk factors of work-related musculoskeletal disorders. The use of different er...

A classification of the literature on the effects of workplace posture on performance of different mental tasks showed few consistent patterns. A parallel classification of the complementary effect of performance on postural variables gave similar results. Because of a lack of data for signal detection tasks, an experiment was performed using 12 ex...

Every new edition of software brings their changes, sometimes important and other times almost unnoticeable. The new edition of Microsoft Word 2007 falls within the first category. An obvious change is the replacement of the menus and toolbars by ribbons. To evaluate the new interface, different methods have been used: interviews, usability testing...
