The objectives of this study were to assess influence of multitasking involving locomotion and concurrent cognitive demands as well as locomotor internal situation model formulation on proactive gait control for hazards. Twenty-four participants navigated a virtual walking environment including locomotion hazards (puddles, potholes). Three variables were manipulated, including a-priori knowledge (three levels of training fidelity), navigation aid type (instructionbased, map-based), and physical cueing (visual only, visual and physical). Significant differences in weight acceptance force and centre of pressure slope suggest that higher environment knowledge and lower cognitive load lead to greater proactive control. Participants adopted a three-stride advance preparation strategy to accommodate hazards. The experiment demonstrated accurate task environment knowledge and situation processing to dictate gait control for hazards when performing concurrent cognitive tasks.

A major impact of information technology in health care has been the introduction of EMRs. Although numerous studies indicate use of EMRs to increase health care quality, there remain concerns with usability issues and safety. A literature search was conducted using Compendex, PubMed, CINAHL, and Web of Science databases to find EMR research published since 2000. Inclusion criteria included relevant English-language papers with subsets of keywords and any studies (manually) identified with a focus on EMR usability. Fifty studies met the inclusion criteria. Results revealed EMR and EHR usability prob...
