The use of Serious Games (SG) in the health domain is expanding. In the field of Neurodegenerative Diseases (ND) such as Alzheimer's Disease, SG are currently employed to provide alternative solutions for patients' treatment, stimulation, and rehabilitation. The design of SG for people with ND implies collaborations between professionals in ND and professionals in SG design. As the field is quite young, professionals specialized in both ND and SG are still rare, and recommendations for the design of SG for people with ND are still missing...

The Acheulean handaxe is one of the longest-known and longest-surviving artifacts of the Palaeolithic and, despite its experimentally tested functionality, is often regarded as puzzling. It is unnecessary to invoke a unique-for-mammals genetic mechanism to explain the handaxe phenomenon. Instead, we propose that two nongenetic processes are sufficient. The first is a set of ergonomic design principles linked to the production of sturdy, hand-held cutting tools in the context of a knapped-stone technology that lacked hafting...

Background: Workplace health promotion (WHP) strongly requires the employer's efforts to improve the psychosocial, ergonomic, and physical environments of the workplace. There are many studies discussing the socio-economic advantage of WHP intervention programmes and thus the internal and external factors motivating employers to implement and integrate such programmes. However, the socio-economic impacts of the employer's multifactorial efforts to improve the work environment need to be adequately assessed...

OBJECTIVE: Acquiring surgical skills requires regular practice. Medical evidence supports that these skills can be learned outside the operating room (OR). The aim of the current study was to describe the first laparoscopic simulator for ureteral reimplantation (LAP-SPUR) following Lich- Gregoir technique. MATERIALS AND METHODS: LAP-SPUR was manufactured using reusable and disposable materials. The technique can be summarized in the following five steps: (1) a transperitoneal approach; (2) extra-vesical ureteral dissection; (3) detrusor division until exposing the mucosa; (4) reimplanting ureter into the new tunnel; and (5) reapproximation and suturing of the detrusor...

BACKGROUND: No previous research has been performed into neck pain among forklift operators. This is a common complaint among these workers, who number around 150,000 in Sweden and six million in Europe. The aim of the study was to examine long-term exposure to unnatural neck positions among forklift operators as a risk factor for neck pain. METHODS: A retrospective cohort study was conducted of all eligible employees at a high-level warehouse. Forklift operators and office workers answered an 18-page questionnaire comprising questions about joint pain, work tasks, work postures and year of start for all items...

This article discusses some of the major theories of the science of human factors/ergonomics (HF/E) in relation to perioperative medicine, with a focus on safety and errors within these systems. The discussion begins with human limitations based in cognition, decision making, stress, and fatigue. Given these limitations, the importance of measuring human performance is discussed. Finally, using the HF/E perspective on safety, high-level recommendations are provided for increasing safety within the perioperative environment...

INTRODUCTION: Movement screens are frequently used to identify abnormal movement patterns that may increase risk of injury or hinder performance. Abnormal patterns are often detected visually based on the observations of a coach or clinician. Quantitative, or data-driven methods can increase objectivity, remove issues related to inter-rater reliability and offer the potential to detect new and important features that may not be observable by the human eye. Applying principal components analysis (PCA) to whole-body motion data may provide an objective data-driven method to identify unique and statistically important movement patterns, an important first step to objectively characterize optimal patterns or identify abnormalities...

Many researchers and practitioners argue the importance of end-user involvement in workplace safety management, but the research literature and practices remain fractured across orientations. The primary aim of this paper is to bridge the gap between two major participatory safety management approaches: behavioral safety and participatory ergonomics. First, an overview and brief history of participative management is presented to provide context for its application to workplace safety. Next, behavioral safety and participatory ergonomics are separately examined in terms of their origins and core elements...

The concept of User System Architectures (USA) is introduced as part of the overall systems architecture. A USA is defined as a set of ergonomics information and knowledge assembled to represent system structure and content. It is described in the context of the system development lifecycle. The characteristics associated with a USA are outlined. These include layers of description, viewpoints, coherency and traceability. The concept of coherency between layers and the techniques for tracing the design characteristics back to the requirements (i...

Most studies concerned with participative ergonomic (PE) interventions, focus on organizational rather than group level analysis. By implementing an intervention at a manufacturing plant, the current study, utilizing advanced information systems, measured the effect of line-supervisor leadership on employee exposure to risks. The study evaluated which PE dimensions (i.e., extent of workforce involvement, diversity of reporter role types and scope of analysis) are related to such exposure at the group level...

Exoskeletons are progressively reaching homes and workplaces, allowing interaction with virtual environments, remote control of robots, or assisting human operators in carrying heavy loads. Their design is however still a challenge as these robots, being mechanically linked to the operators who wear them, have to meet ergonomic constraints besides usual robotic requirements in terms of workspace, speed, or efforts. They have in particular to fit the anthropometry and mobility of their users. This traditionally results in numerous prototypes which are progressively fitted to each individual person...
