Apports de la réalité virtuelle à la prise en charge de troubles cognitifs et comportementaux

Abstract : Virtual reality technology allows the user to be an active participant, by means of various interfaces, in a three-dimensional world generated by the computer. Therapists became acquainted with the possibilities of this new interaction paradigm, and contributed to the development of virtual environments for diagnosis, therapy, rehabilitation and assessment. We chose to focus on the assessment and the treatment of the cognitive and behavioral disorders met in psychiatry and neuropsychology.
Virtual reality technology offers new means to evaluate and rehabilitate cognitive functions. It allows us to overcome some difficulties inherent in traditional methods and provides more appropriate solutions. Typically, “paper and pencil” tasks are replaced by simulations of daily life activities. The contribution of this research concerns the appropriacy of the virtual reality approach to diagnosis and therapy, and the resulting benefits.
Two little-researched subjects held our attention : the treatment of social phobia in psychiatry, and the assessment of action planning in neuropsychology. Our first objective was to design an application based on virtual reality for each of these subjects and to evaluate the feasibility. The second objective was to identify the contribution of virtual reality to the assessment and treatment of human dysfunctions.
The design and the implementation of a therapeutic treatment of social phobia, based on virtual reality, brought different challenges: the design of social interaction situations arousing emotional reactions among social phobic patients; the investigation of the various types of social phobia, showed the efficacy of the virtual reality therapy.
The design of a virtual system dedicated to human cognitive dysfunctions led us to tackle the assessment of action planning. It is based on the design of a planning task and a virtual environment, both of them called ecological. The application was unfolded in the context of aging and Parkinson's disease. The study, carried out among patients suffering from Parkinson's disease, helped us see the relevance and the potential of virtual reality approach.
According to the experiments we carried out, we are now able to identify the contribution of virtual reality to the assessment and treatment of cognitive and behavioral disorders. The contribution features, such as stimuli control, flexibility, etc. opens the way to new topics of reflection related to the role of virtual reality in the clinical process.
