Many post-stroke patients, especially those with frontal lobe lesions, have chronic impairments in mental flexibility, leading to difficulties in decision-making, action planning, or behavioural perseverance. Techniques for remediation of these dysexecutive disorders are often performed in a hospital or in a liberal office. The possible progress resulting from this rehabilitation is rarely transposed into the patient daily life performances, executed in a richer and less controlled environment than the usual place of re-educational. Here, we wish to assess the effective benefits (i.e. in carrying out the activities of daily living) of a computerized rehabilitation program addressing executive functions and based on virtual reality, simulating ADLs. We use in this study a multiple baseline single case experimental design (AB design with a follow-up beyond), including for each patient: pretreatment (phase A), treatment (phase B), and follow-up phase.~Pretreatment includes a routine sensitivomotor neurological rehabilitation program that doesn't specifically target executive functions in daily living activities (3 to 5 weeks depending on randomization). Treatment consists in a 4 weeks virtual reality cognitive training program, including four 45-minute sessions per week with an occupational therapist for cognitive rehabilitation in a virtual environment with the COVIRTUA Cognition software. The follow-up phase (5 to 3 weeks depending on randomization) includes no support for executive functions, either in a rehabilitation centre or in a liberal office.
This research aims to evaluate the effects of a cognitive reeducation carried out with the COVIRTUA Cognition software using a virtual environment, on real-life execution of activities of daily living (ADL) for patients with post-stroke dysexecutive disorders. We will assess patients' performances in achieving ADLs by the Goal Attainment Scaling (GAS) throughout the follow-up (3 months), based on the goals set at the beginning of management with each patient.
