For this study, we evaluated two training interventions for improving gait parameters in individuals with poststroke hemiplegia using a training methodology that required them to step over objects. Gait velocity, step length, ability to step over obstacles, and walking endurance were compared before and after 2 weeks of training and 2 weeks after cessation of training. Twenty subjects with post...

The Kiel locomotor maze requires participants to choose five targets from among 20 locations marked by small red lights on the floor of a dimly lit circular environment having four wall-mounted extramaze cues and two intramaze cues at floor level. In the present study, acquisition of the real task was examined in 11-year-old children following prior accurate training in a virtual version, follo...

We set up a library of virtual fixtures with both haptic and graphic properties and behaviors. For a given task, Virtual Fixture Assembly Language (VFAL) could be used to construct various virtual fixture series, with graphic and force guidance rules, making the low-level haptic and graphic rendering details transparent to the developers. An experiment evaluated the application of virtual fixtu...

In virtual training scenarios, agent technology can be used to build a virtual tutor that assists a student during training. In a dialogue using argumentation schemes, the virtual tutor provides reasons to the students to explain why a particular action is the most sensible. The tutor determines the best action using practical reasoning. The justification of this action is selected based on the...

This paper shows a distributed simulation framework for tactical training in networked virtual environment. The existing military training simulation systems are mostly full simulated systems operating on single platform. They are to train individual’s operation skill, but don’t support team level tactical training. In order to train team level combat and command skill in dynamic battlefield, t...

The use of virtual environment (VE) for training sports is quite natural when considering strategic or cognitive aspects. Using VE for sensorimotor training is more challenging, in particular with the difficulty of transferring the task learned in the virtual world to the real. Of special concern for the successful transfer is the adequate combination of training experience protocols and the de...

The objective of this research is to present a discussion about concepts and steps necessary to develop Virtual Reality environments for simulation and training of medical procedures. Thus, were related the main features of systems found in scientific literature in order to distinguish difficulties in creating virtual simulators, verify results achieved and point out future trends in simulation...

Background and objectives: Educational technology is widely used in all parts of medical education. The use and application of common educational technologies and adoption of educational design patterns in medical sciences education can greatly help in medical simulations, training, and improving of clinical skills of nurses and medical students. The aim of this research was to study computer-a...
