Association between prism adaptation and auditory cues on spatial navigation in individuals with unilateral neglect / Mélanie Cogné in Annals of physical and rehabilitation medicine, Vol. 63, n°1 (Janvier 2020)
[article]
Titre : Association between prism adaptation and auditory cues on spatial navigation in individuals with unilateral neglect Type de document : texte imprimé Auteurs : Mélanie Cogné ; Etienne Guillaud ; Laurène Guillot ; Evelyne Klinger ; Bertrand Glize ; Sophie Jacquin-Courtois ; Jean-René Cazalets ; Pierre-Alain Joseph Année de publication : 2020 Article en page(s) : p. 12-20 Note générale : doi.org/10.1016/j.rehab.2019.03.005 Langues : Anglais (eng) Mots-clés : 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.Permalink : ./index.php?lvl=notice_display&id=90682

[article]
Titre : Complex regional pain syndrome associated with hyperattention rather than neglect for the healthy side: A comprehensive case study Type de document : texte imprimé Auteurs : Laure Christophe ; Ludovic Delporte ; Patrice Revol ; [et al...] Année de publication : 2016 Article en page(s) : p. 294-301 Langues : Français (fre) Mots-clés : CRPS Pain Spatial neglect Body representation Reference frame Motor neglect ADL Prism adaptation Résumé : Complex regional pain syndrome (CRPS) is a dehabilitating chronic condition occurring with peripheral lesions. There is growing consensus for a central contribution to CRPS. Although the nature of this central body representation disorder is increasingly debated, it has been repeatedly argued that CRPS results in motor neglect of the affected side. The present article describes a comprehensive and quantitative case report demonstrating that: (1) not all patients with chronic CRPS exhibit decreased spatial attention for the affected side and (2) patients may actually exhibit a substantial, broad and reliable attentional bias toward the painful side, akin to spatial neglect for the healthy side. This unexpected result agrees with the idea that patients can be hyper-attentive toward their pathological side as a manifestation of lowered pain threshold, allodynia and kinesiophobia.
