Tags : Spatial navigation Neglect Virtual reality Cues Prism adaptation Résumé : Background: Unilateral neglect is common among right-hemispheric stroke individuals and also concerns the auditory modality. Prism adaptation can improve auditory extinction during a dichotic listening task, but its effect during an ecological task has not been studied.
Objective: The main objective was to evaluate whether lateralized cueing before and after prism adaptation improved virtual spatial navigation of stroke individuals with visual and auditory unilateral neglect. Secondary objectives were to assess spatial memory and obtain a better understanding of the mechanism of the cueing treatment by using an eye-tracker.
Methods: We included 22 stroke individuals with left visual and auditory neglect, 14 individuals without neglect, and 12 healthy controls. After a familiarization task, participants underwent 3 evaluation sessions. Participants were first passively shown a path that they had then to actively reproduce by using a joystick. A path with lateralized beeping sounds indicating direction and a path without any sounds were followed in a randomized order. After prism adaptation, the participants followed a third path with lateralized beeping sounds. The time of navigation and number of trajectory mistakes were recorded. After navigation, spatial memory was assessed. Additionally, an eye-tracker was used during the navigation period.
Results: The navigational performance of participants with neglect was significantly better with than without auditory cues, especially after prism adaptation. With auditory cues, participants without neglect reached the navigational performance of healthy controls. The spatial memory of individuals with neglect was significantly lower with auditory cues. Eye-tracking analyses showed that participants with neglect made more saccades and looked longer at the right-square angles in the absence of auditory cues.
Conclusions: This study demonstrates the positive effect of auditory cues in virtual spatial navigation of individuals with visual and auditory neglect and the potentiation of the help of cues after prism adaptation.En ligne : http://www.em-consulte.com/produit/rehab Permalink : https://ifm3r.centredoc.fr/index.php?lvl=notice_display&id=17751 [article]The contribution of virtual reality to the diagnosis of spatial navigation disorders and to the study of the role of navigational aids: A systematic literature review / Mélanie Cogné in Annals of physical and rehabilitation medicine, Vol. 60 n° 3 (June 2017)

CerveauTags : Spatial navigation Virtual reality Brain-damaged patients Ageing Stimuli Aid Résumé : Introduction : Spatial navigation, which involves higher cognitive functions, is frequently implemented in daily activities, and is critical to the participation of human beings in mainstream environments. Virtual reality is an expanding tool, which enables on one hand the assessment of the cognitive functions involved in spatial navigation, and on the other the rehabilitation of patients with spatial navigation difficulties. Topographical disorientation is a frequent deficit among patients suffering from neurological diseases. The use of virtual environments enables the information incorporated into the virtual environment to be manipulated empirically. But the impact of manipulations seems differ according to their nature (quantity, occurrence, and characteristics of the stimuli) and the target population.
Methods : We performed a systematic review of research on virtual spatial navigation covering the period from 2005 to 2015. We focused first on the contribution of virtual spatial navigation for patients with brain injury or schizophrenia, or in the context of ageing and dementia, and then on the impact of visual or auditory stimuli on virtual spatial navigation.
Results : On the basis of 6521 abstracts identified in 2 databases (Pubmed and Scopus) with the keywords « navigation » and « virtual », 1103 abstracts were selected by adding the keywords “ageing”, “dementia”, “brain injury”, “stroke”, “schizophrenia”, “aid”, “help”, “stimulus” and “cue”; Among these, 63 articles were included in the present qualitative analysis.
Conclusion : Unlike pencil-and-paper tests, virtual reality is useful to assess large-scale navigation strategies in patients with brain injury or schizophrenia, or in the context of ageing and dementia. Better knowledge about both the impact of the different aids and the cognitive processes involved is essential for the use of aids in neurorehabilitation.En ligne : http://www.em-consulte.com/produit/rehab Permalink : https://ifm3r.centredoc.fr/index.php?lvl=notice_display&id=14915 [article]Influence of non-contextual auditory stimuli on navigation in a virtual reality context involving executive functions among patients after stroke / Mélanie Cogné in Annals of physical and rehabilitation medicine, Vol. 61 n° 6 (November 2018)

Fonction exécutive , OuïeTags : Spatial navigation Virtual reality VAP-S Auditory stimuli Executive functions Inhibit Résumé : Background: Topographical disorientation is frequent among patients after a stroke and can be well explored with virtual environments (VEs). VEs also allow for the addition of stimuli. A previous study did not find any effect of non-contextual auditory stimuli on navigational performance in the virtual action planning-supermarket (VAP-S) simulating a medium-sized 3D supermarket. However, the perceptual or cognitive load of the sounds used was not high.
Objective: We investigated how non-contextual auditory stimuli with high load affect navigational performance in the VAP-S for patients who have had a stroke and any correlation between this performance and dysexecutive disorders.
Methods: Four kinds of stimuli were considered: sounds from living beings, sounds from supermarket objects, beeping sounds and names of other products that were not available in the VAP-S. The condition without auditory stimuli was the control. The Groupe de réflexion pour l’évaluation des fonctions exécutives (GREFEX) battery was used to evaluate executive functions of patients.
Results: The study included 40 patients who have had a stroke (n = 22 right-hemisphere and n = 18 left-hemisphere stroke). Patients’ navigational performance was decreased under the 4 conditions with non-contextual auditory stimuli (P < 0.05), especially for those with dysexecutive disorders. For the 5 conditions, the lower the performance, the more GREFEX tests were failed. Patients felt significantly disadvantaged by the non-contextual sounds sounds from living beings, sounds from supermarket objects and names of other products as compared with beeping sounds (P < 0.01). Patients’ verbal recall of the collected objects was significantly lower under the condition with names of other products (P < 0.001). Left and right brain-damaged patients did not differ in navigational performance in the VAP-S under the 5 auditory conditions.
Conclusions: These non-contextual auditory stimuli could be used in neurorehabilitation paradigms to train patients with dysexecutive disorders to inhibit disruptive stimuli.En ligne : http://www.em-consulte.com/produit/rehab Permalink : https://ifm3r.centredoc.fr/index.php?lvl=notice_display&id=16398 [article]
