- Measures of neuropsychological assessment as indicators of success in neuropsychological rehabilitation: an exploratory correlational studyPublication . Mendes, Liliana; Barbosa, F.; Reis, L.P.Neuropsychological assessment not only allows diagnosing possible neurocognitive impairments in domains such as attention, working memory, and executive functions, but can also provide useful information for the neuropsychological rehabilitation. By applying a set of valid neuropsychological tests to individuals with Acquired Brain Injury (ABI), and subsequently studying how patients’ performance in rehabilitation programs relates with measures that are commonly provided by these tests, we may obtain valuable predictors of individual success that can be considered in neuropsychological rehabilitation.
- Medidas de avaliação neuropsicológica e indicadores de sucesso na reabilitação neuropsicológica: um estudo correlacional exploratórioPublication . Mendes, Liliana; Dores, Artemisa Rocha; Carvalho, Irene P.; Barbosa, FernandoEste estudo procurou identificar quais as medidas de avaliação neuropsicológica que podem orientar melhor os terapeutas na seleção de tarefas de reabilitação neurocognitiva e para ajustar a dificuldade das mesmas tarefas ao potencial de cada pessoa com lesão cerebral adquirida (LCA).
- Realidade virtual e reabilitação neurocognitiva da lesão cerebral adquirida – estudo exploratórioPublication . Mendes, Liliana; Barbosa, Fernando; Reis, Luís PauloAo longo de décadas várias têm sido as tentativas de estudar a utilidade de ambientes virtuais ecológicos na reabilitação neurocognitiva de sujeitos com lesão cerebral adquirida. Com o presente estudo pretendemos verificar a aplicabilidade de ambientes virtuais ecológicos não imersivos na remediação de défices cognitivos. Oito participantes com lesão cerebral adquirida, foi sujeito a 40 sessões de RN com recurso a uma plataforma de RV não-emersivo disponível on-line (VICERAVI – Virtual Centre for the Rehabilitation of Road Accident Victims). Os participantes realizaram uma avaliação neuropsicológica pré e pós-teste de distintos domínios atenção, memória, linguagem e funcionamento executivo. Nos testes D2, TMT A&B, Stroop (interferência palavra-cor), HVLT-R e WMS-III, encontramos diferenças estatisticamente significativas entre o primeiro e o segundo momento de avaliação. A reabilitação neurocognitiva on-line pode ser favorável à compensação de défices cognitivos.
- Significance of virtual reality-based rehabilitation in acquired brain injuryPublication . Dores, Artemisa Rocha; Mendes, Liliana; Carvalho, Irene P.; Guerreiro, Sandra; Almeida, Isabel; Barbosa, FernandoRecent research has shown the potential of Virtual Reality (VR) in the field of rehabilitation, namely neurocognitive rehabilitation. This technology will certainly revolutionize the rehabilitation of the future. Its advantages include greater ecological validity than conventional rehabilitation methods, provision of safe contexts for learning/training, the possibility of programs to be contingent on patient performance, with increasing levels of task difficulty and provision of immediate feedback, and the use of a “game factor” that promotes motivation for participation. These are important aspects in the rehabilitation of patients with acquired brain injury. Patients with this and other types of neurological injuries endure cognitive deficits that cause difficulties in independent functioning and daily-life activities. Their rehabilitation calls for systematic intervention programs that are theoretically grounded and use innovative approaches to their advantage. In this paper we present a review about the advantages of VR in the generalization of acquired skills to real-life contexts, to promote patients' functionality and quality of life, and propose an innovative program of neurocognitive rehabilitation. Research in the field shows positive effects of VR programs, but urges progress in terms of the development of techniques (e.g., facial synthesis and of more research on the impact of these interventions. Future studies should also explore the existence of neuro-anatomical correlates of behavioral changes, contributing to the investigation of the relationship between neural plasticity and behavior and providing evidence for clinical practice.
- Virtual centre for the rehabilitation of road accident victims (VICERAVI)Publication . Mendes, Liliana; Dores, Artemisa Rocha; Barbosa, Fernando; Rego, Paula Alexandra; Moreira, Pedro Miguel; Reis, Luís Paulo; Viana, José; Coelho, António; Sousa, ArmandoThe main objective of this work is to describe the Virtual Center for the Rehabilitation of Road Accident Victims - VICERAVI and the serious games it includes for the purpose of neuropsychological rehabilitation. The validation of the VICERAVI as a rehabilitation system involves 30 participants of both sexes, with brain injury due to road accidents. The applicability and the benefits of virtual worlds for a holistic neuropsychological rehabilitation will be tested using virtual reality (OpenSimulator) to simulate tasks of everyday life, enabling participants to perform cognitive and social skills training through their avatars. The progresses of this group will be compared with a group of conventional neuropsychological rehabilitation. The main innovation of the work is the possibility of administering neuropsychological rehabilitation at distance, via ecological virtual environments. Moreover, the paper discusses also relevant criteria and issues in respect to the use of serious games, simulation and virtual environments in rehabilitation.
- Virtual City: Neurocognitive rehabilitation of Acquired Brain InjuryPublication . Dores, Artemisa Rocha; Miranda, Maria João; Carvalho, Irene Palmares; Mendes, Liliana; Barbosa, Fernando; Coelho, António; Sousa, Liliana de; Castro Caldas, AlexandreAcquired Brain Injury (ABI) is one of the leading causes of individuals' reduced participation in various contexts of life, compromising autonomous functioning and performance in complex activities. Neurocognitive rehabilitation, carried out by transdisciplinary teams, is part of the intervention after the acute phase, aiming patients' maximum functionality and quality of life. Serious games and virtual reality begin to provide innovative solutions in this area. In this study, a prototype platform for the rehabilitation of executive functioning and other related cognitive functions is presented: the Virtual City. Part of a larger project, it consists of urban virtual environments that simulate real-life scenarios and activities. Tests will be performed to validate it as a tool for the rehabilitation of ABI.
