Study Description

After a stroke, a wide range of neurological disorders can occur. One of them is impairments of the visual-oculomotor system in 8-31% of cases. Such patients experience loss of visual fields, hemianopia, tunnel vision, diplopia. All this causes great difficulties for returning to everyday life, as well as to professional activity. The eye tracking method allows to diagnose and evaluate the effectiveness of training aimed at improving the functioning of the saccadic system, reducing the volume of visual deficit. Currently, eye tracking is represented by a variety of technological solutions, but not all of them are used in the clinic.

The aim of the study is the application of an eye tracking-based device in cerebral stroke survivors for the correction of oculomotor disorders and visual attention functions.

Stroke patients participate in the study in Federal Center of Brain Research and Neurotechnologies of the Federal Medical Biological Agency, Moscow, Russia. The study has been conducted since January, 10 and was approved by a local ethic committee and followed principles of the Declaration of Helsinki. The patients stay in a 24-hour hospital and undergo a rehabilitation course. For 3 weeks, patients receive daily training on the C-Eye Pro device, AssisTech Sp. z. o. o, Poland. The patients interact with the device only by using eye movements. Participants undergo a primary assessment of cognitive functions (memory, thinking skills, language, visual-spatial and communicative functions). According to the results of the diagnosis, participants are offered a scheme of correctional training and secondary assessment at the end of the training. Correction training consists, firstly, of 10-minute exercise at the beginning of each session, aimed at improving visual functions and attention. Patients have to follow the spontaneously moving object. The result is evaluated qualitatively using heat and scanpath maps. Secondly, the correctional training includes a block of neurorehabilitation (simple cognitive exercises similar to the tasks presented in assessment).
