“…These VR outcomes are consistent with the severity of the attentional impairments and support the results of previous studies (Kim et al, 2010;Kim et al, 2004;Peskine et al, 2011;Jannink, Aznar, Kort, van de Vis, Veltink, & van der Kooij, 2009). Previous research has also demonstrated that head rotations and other parameters can distinguish stroke subjects with USN from those without neglect.…”

“…Previous research has also demonstrated that head rotations and other parameters can distinguish stroke subjects with USN from those without neglect. For instance, the rotation angle of the head to the left has been reported to be smaller than the rotation angle to the right (Myers & Bierig, 2000), and the left-to-right reaction time has been reported to be higher (Peskine et al, 2011) in stroke subjects with neglect. In our study, healthy subjects and stroke participants with USN showed a similar and balanced number of head turns to both sides.…”

“…The system presented by Katz et al (Katz, Ring, Naveh, Kizony, Feintuch, & Weiss, 2005) and Weiss et al (Weiss, Naveh, & Katz, 2003) had graphical limitations and used the arrow keys of a keyboard to point the avatar's head left, right or forward to see whether vehicles were approaching from either direction. To overcome these limitations, Kim et al (Kim et al, 2010) and Peskine et al (Peskine et al, 2011) developed a 3D immersive world and used an HMD in an attempt to provide participants with a more realistic street-crossing scenario. However, the benefits of the increased realism may have been to the detriment of usability and cost.…”

“…Three previous studies have used 3D virtual street environments to assess (Kim et al, 2010;Peskine et al, 2011) and treat (Katz, Ring, Naveh, Kizony, Feintuch, & Weiss, 2005;Weiss, Naveh, & Katz, 2003) USN in a stroke population. While the assessment systems allowed subjects to interact using a head mounted display (HMD), a head tracker, and a mouse, the training system used a desktop monitor and a keyboard.…”

Unilateral spatial neglect is a common consequence of stroke that directly affects the performance of activities of daily living. This impairment is traditionally assessed with paper-and-pencil tests that can lack correspondence to real life and are easily compensated. Virtual reality can immerse patients in more ecological scenarios, thus providing therapists with new tools to assess and train the effects of this impairment in simulated real tasks. This paper presents the clinical validation and convergent validity of a low-cost virtual reality system for training street-crossing in stroke patients with and without neglect. The performance of neglected patients was significantly worse than the performance of non-neglected and healthy participants. In addition, several correlations between the scores in the system and in the traditional scales were detected.

“…They indicate that it is unclear at present which characteristics of VR are most important and that it is unknown whether effects can be sustained in the longer term. In neglect patients, VR has been recently applied both for diagnostic purposes (Broeren et al, 2007;Buxbaum et al, 2008Buxbaum et al, , 2012Jannink et al, 2009;Kim et al, 2010;Van Kessel et al, 2010, 2013aFordell et al, 2011;Peskine et al, 2011;Dvorkin et al, 2012) and as a rehabilitation tool (Webster et al, 2001;Castiello et al, 2004;Katz et al, 2005;Ansuini et al, 2006;Kim et al, 2007Kim et al, , 2011Smith et al, 2007;Sedda et al, 2012;Van Kessel et al, 2013b). In their review on the use of VR in the assessment and treatment of neglect, Tsirlin et al (2009) argue that an important benefit of VR technologies is that they provide rich and realistic environments with a high level of control over their parameters and thus allow for training in a safe and cost effective way.…”

Visuospatial neglect due to right hemisphere damage, usually a stroke, is a major cause of disability, impairing the ability to perform a whole range of everyday life activities. Conventional and long-established methods for the rehabilitation of neglect like visual scanning training, optokinetic stimulation, or limb activation training have produced positive results, with varying degrees of generalization to (un)trained tasks, lasting from several minutes up to various months after training. Nevertheless, some promising novel approaches to the remediation of left visuospatial neglect have emerged in the last decade.These new therapy methods can be broadly classified into four categories. First, non-invasive brain stimulation techniques by means of transcranial magnetic stimulation (TMS) or transcranial direct current stimulation (tDCS), after a period of mainly diagnostic utilization, are increasingly applied as neurorehabilitative tools. Second, two classes of drugs, dopaminergic and noradrenergic, have been investigated for their potential effectiveness in rehabilitating neglect. Third, prism adaptation treatment has been shown to improve several neglect symptoms consistently, sometimes during longer periods of time. Finally, virtual reality technologies hold new opportunities for the development of effective training techniques for neglect. They provide realistic, rich, and highly controllable training environments. In this paper the degree of effectiveness and the evidence gathered to support the therapeutic claims of these new approaches is reviewed and discussed. The conclusion is that for all these approaches there still is insufficient unbiased evidence to support their effectiveness. Further neglect rehabilitation research should focus on the maintenance of therapy results over time, on a more functional evaluation of treatment effects, on the design and execution of true replication studies and on the exploration of optimal combinations of treatments.

Unilateral Spatial Neglect is a cognitive impairment commonly observed in patients after right hemispheric lesions. A patient with this condition will show a lack of attention or response to visual stimuli presented to the left space.In order to assess visual neglect, several "paper and pencil" tests are traditionally used, like the Albert's Test or the Bells Test. Computer supported tests have been also proposed like Visual Spatial Search Task (VISSTA) or Starry Night Test (SNT). In this kind of tests, the patient is asked to detect all occurrences of a target among distractors ("cancellation task"). However, it has been noticed that these tests are not able to identify subtle but relevant NSU, especially in the chronic stage. In addition, compensatory attentional strategies can be developed by the patients in order to pass a test in which they have unlimited time. It is then important to measure reaction time and to adapt tests to increase diagnostic accuracy.This abstract presents READAPT an application supporting the Bells Test, with the aim of overcoming the limits of existing static paper-and-pencil diagnostic tools and to facilitate recording and analysis of patient's visual scanning.
