Virtual reality for spinal cord injury-associated neuropathic pain: Systematic review / B. Chi in Annals of physical and rehabilitation medicine, Vol. 62, n°1 (Janvier 2019)
[article]
Titre : Virtual reality for spinal cord injury-associated neuropathic pain: Systematic review Type de document : texte imprimé Auteurs : B. Chi ; B. Chau ; E. Yeo ; P. Ta Année de publication : 2019 Article en page(s) : p. 49-57 Note générale : Doi : 10.1016/j.rehab.2018.09.006 Langues : Anglais (eng) Mots-clés : Virtual reality Spinal cord injury Neuropathic pain Résumé : Background
Treatment of spinal cord injury (SCI)-associated neuropathic pain is challenging, with limited efficacy and no definitive options, and SCI patients often show resistance to pharmacologic treatment. Virtual reality (VR) therapy is a non-invasive, non-pharmacologic alternative with minimal adverse effects.
Objective
To investigate the effect of VR therapy on SCI-associated neuropathic pain in a systematic review.
Methods
Articles needed to 1) be written in English; 2) include adult subjects, with at least half the study population with a SCI diagnosis; 3) involve any form of VR therapy; and 4) assess neuropathic pain by quantitative outcome measures. Articles were searched in MEDLINE/PubMed, CINAHL®, EMBASE, and PsycINFO up to April 2018. Reference lists of retrieved articles were hand-searched. Methodologic quality was assessed by the Physiotherapy Evidence Database Score (PEDro) for randomized controlled trials and Modified Downs and Black Tool (D&B) for all other studies. Level of evidence was determined by using a modified Sackett scale.
Results
Among 333 studies identified, 9 included in this review (n=150 participants) evaluated 4 methods of VR therapy (virtual walking, VR-augmented training, virtual illusion, and VR hypnosis) for treating neuropathic pain in SCI patients. Each VR method reduced neuropathic pain: 4 studies supported virtual walking, and the other 3 VR methods were each supported by a different study. Combined treatment with virtual walking and transcranial direct current stimulation was the most effective. The quality of studies was a major limitation.
Conclusion
VR therapy could reduce SCI-associated neuropathic pain, although the clinical significance of this analgesic effect is unclear. Clinical trials evaluating VR therapy as standalone and/or adjunct therapy for neuropathic pain in SCI patients are warranted.Permalink : ./index.php?lvl=notice_display&id=82639

Exclu du prêtInfluence 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 (Novembre 2018)
[article]
Titre : Influence of non-contextual auditory stimuli on navigation in a virtual reality context involving executive functions among patients after stroke Type de document : texte imprimé Auteurs : Mélanie Cogné ; Marie-Hélène Voilleau ; Evelyne Klinger ; Pierre-Alain Joseph Année de publication : 2018 Article en page(s) : p. 372-379 Note générale : Doi : 10.1016/j.rehab.2018.01.002 Langues : Anglais (eng) Mots-clés : 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.Permalink : ./index.php?lvl=notice_display&id=82387

Exclu du prêtModulating the internal model of verticality by virtual reality and body-weight support walking: A pilot study / Anaïs Odin in Annals of physical and rehabilitation medicine, Vol. 61, n°5 (Septembre 2018)
[article]
Titre : Modulating the internal model of verticality by virtual reality and body-weight support walking: A pilot study Type de document : texte imprimé Auteurs : Anaïs Odin ; Dominique Faletto-Passy ; Franck Assaban ; Dominic Pérennou Année de publication : 2018 Article en page(s) : p. 292-299 Note générale : Doi : 10.1016/j.rehab.2018.07.003 Langues : Anglais (eng) Mots-clés : Verticality perception Sense of upright Body-weight support walking Virtual tilted room Virtual reality Modulation Lateropulsion Résumé : Background and objective
The study aimed at inducing a visual vertical (VV) bias by immersion in a virtual tilted room (VTR, visual cues), then testing the effect of 30% body-weight support walking (BWSW, somaesthetic cues) to correct this bias.
Methods
We included 20 healthy participants (median age 54 years; 12 females) who wore the Oculus-Rift® Head Mounted Display to produce the virtual reality and generate the VV. VV (8 trials) was tested at baseline, then in 3 postural conditions (walking, sitting and BWSW), by 2 visual conditions (darkness and VTR), according to a pseudo-randomized blocked design. The VTR was tilted 18° clockwise. Data for 3 participants with virtual reality sickness were discarded, and those for 17 participants underwent non-parametric statistical analysis by 2 main criteria: VV and head orientation.
Results
The VTR induced a pronounced tilt of the vertical toward the tilted side under the baseline condition (median 11.4° [Q1–Q3 6.1–13.4]; P<0.01), with a large effect size (r=0.88). The effect was systematic, with great inter-individual variability (2–17°), and was similar under every postural condition (P<0.001), with a post-effect lasting 6min and suppressed under BWSW. In darkness, VV was more upright during BWSW than sitting (P<0.05), with a medium effect size (r=0.49). The VTR induced a slight head tilt of median 3.3° [2.8–5.9] toward the tilted side under every postural condition (P<0.001), with a large effect size (r=0.87). In darkness, the head was upright only at baseline and under BWSW.
Conclusion
Being immersed in a tilted environment induces a powerful bias in verticality perception (11°). Contrary to our hypothesis, BWSW did not attenuate the effect induced by the VTR, probably because of the power of this effect. However, BWSW was the only postural condition able to suppress post-effects induced by the VTR, thereby leading to the head and VV oriented upright. BWSW may improve verticality representation, presumably by bringing augmented information about the direction of the Earth vertical. These findings represent an avenue for rehabilitation of patients with postural disorders caused by a wrong verticality representation. Technological improvements will be necessary to attenuate the virtual reality discomfort.Permalink : ./index.php?lvl=notice_display&id=80620

Titre : Virtually home: Feasibility study and pilot randomised controlled trial of a virtual reality intervention to support patient discharge after stroke Type de document : texte imprimé Auteurs : Kate Threapleton ; Karen Newberry ; Greg Sutton ; Esme Worthington ; Avril Drummond Année de publication : 2018 Article en page(s) : p. 196-2016 Langues : Anglais (eng) Mots-clés : Occupational therapy virtual reality stroke rehabilitation discharge planning home visits Résumé : Introduction
Virtual reality has the potential to assist occupational therapists in preparing patients for discharge by facilitating discussions and providing education about relevant practical issues and safety concerns. This study aimed to explore the feasibility of using a virtual reality intervention to support patient discharge after stroke and pilot its use.
Method
Practical aspects of delivering a virtual reality intervention prior to discharge were explored by means of a non-randomised feasibility study and a subsequent pilot randomised controlled trial. Factors considered included eligibility, recruitment, intervention delivery, attrition and suitability of outcome measures. Outcome measures included standardised assessments of stroke severity, mobility, health-related quality of life, functional ability, satisfaction with services and concerns about falling.
Results
Thirty-three participants were recruited in total: 17 to the feasibility study and 16 to the pilot trial. At 1-month follow-up, 14 participants (82%) were re-assessed in the feasibility study and 12 (75%) in the pilot trial. The main difficulties encountered related to recruitment, particularly regarding post-stroke cognitive impairments, the presence of mild deficits or illness.
Conclusion
It was feasible to recruit and retain participants, deliver the intervention and collect outcome measures, despite slow recruitment rates. These findings could inform the design of a definitive trial.Permalink : ./index.php?lvl=notice_display&id=80067

This methodology is based on a virtual reality setup in which a real goalkeeper is facing a virtual player and a virtual defensive wall. The setup has been improved to provide a total freedom of movement to the goalkeeper in order to have a realistic interaction between the goalkeeper and the player. The goalkeeper’s movements are captured in real-time to accurately analyze his reactions. Such a methodology not only represents a valuable research tool but also provides a relevant training tool. Using this setup, this paper shows that goalkeepers are more performant during free kick with a wall composed of 5 defenders whatever its position.
