Transcranial direct current stimulation (tdcs) and visual stimulation (vs) for visual field restitution after stroke: case report

The visual field is fundamental for the construction of human perception. Despite this understanding, its evaluation and treatment remain forgotten during the process of functional rehabilitation in individuals with neurological injury. There is still no consensus on the forms of treatment that can be used. Therefore, it was observed the importance of exposing the results of a case in which a patient was submitted to a protocol with Transcranial Direct Current Stimulation (tDCS), associated with Visual Stimulation (VS) for restitution of visual field lost after Ischemic Stroke (IS). The intervention lasted 90 days, with two intensive protocols of 15 days (with daily sessions) and weekly maintenance sessions for two months, which was the interval between each intensive protocol. After the intervention, partial restitution of the affected visual field was observed, as well as an improvement in the result in the execution of the activities presented as the main complaint, in addition to the evolution of the situation of insufficiency of adjacent convergence. It was possible to verify that an intervention protocol with tDCS, associated with VS, could promote positive effects in relation to the restitution of the visual field in an adult patient after stroke, providing improvement in quality of life and in the execution of activities of daily living.
