Item Computerized cognitive training using virtual reality on everyday life activities for patients recovering from stroke(2020-04-07) Oliveira, Jorge; Gamito, Pedro; Lopes, Beatriz; Silva, Ana Rute Tavares; Galhordas, João; Pereira, Eduarda; Ramos, Elisabete; Silva, Ana Paula Lopes da; Jorge, Áurea; Fantasia, António; HEI-LAB (FCT) - Digital Laboratories for Environments and Human InteractionsRecent studies argue that the use of virtual reality tasks depicting activities daily living may be an effective means for cognitive rehabilitation. The aim of this study was to test an ecologically oriented approach in virtual reality resembling the demands of everyday life activities for cognitive rehabilitation following stroke. The sample comprised 30 sub-acute stroke patients recovering from stroke in a rehabilitation hospital. They were assessed in a single-arm pre-post intervention study on global cognition, executive functions, memory and attention abilities. The intervention consisted of virtual reality in a multidomain cognitive training approach depicting everyday life tasks (preparing food, choosing clothes, shopping, etc.). Improvements were found in the assessed cognitive domains at 6 to 10 post-treatment sessions. In-depth analysis through reliable change scores has suggested larger treatment effects on global cognition. Overall results suggest that the use of virtual reality-based exercises on everyday life activities may be a useful cognitive rehabilitation approach to provide short-term gains in cognition following stroke.Item VR-based assessment and intervention of cognitive functioning after stroke(2020) Gamito, Pedro; Souto, Maria Teresa Soares; Dias, Ana Rita Conde; Salvador, Ágata; Galhordas, João; Oliveira, Jorge; HEI-LAB (FCT) - Digital Laboratories for Environments and Human InteractionsWorldwide, stroke affects one out of every six individuals, being associated with physical and cognitive impairments, and leaving a striking footprint on individuals, their families and society. Assessment of acquired deficits and rehabilitation of lost and compromised functions is based typically on exercises that may not replicate the demands of everyday life activities lacking ecological validity. These tests fail at predicting daily functioning and their similarity with daily life activities is far from being sound. Assessing and training cognitive functions under an ecologically oriented approach, i.e. using exercises that replicate instrumental activities of daily living (IADL) seems to be the suitable strategy to follow. Virtual Reality (VR) worlds have been used to simulate IADL for assessment and rehabilitation of acquired cognitive deficits since the late 1990’s. This chapter reports and debates existing studies that support the use of VR in this context. When it comes down to veridicality and verisimilitude, evidences illustrate the opportunity of adopting this strategy that outperforms traditional paper and pencil exercises. A glance through the perspective of a therapist, that has adopted VR for cognitive rehabilitation in patients with stroke is also debated.
