- Original description
The goal of this clinical trial is to investigate whether optokinetic stimulation delivered without a reading task can improve reading performance in adults with post-stroke hemianopic alexia. The main question it aims to answer is: does optokinetic stimulation without a reading task improve reading speed more than optokinetic stimulation with a reading task? Optokinetic stimlation with a reading task is considered the standard rehabilitation. These two conditions will be administered according to a randomized crossover design to determine wether the presence or absence of a reading task influences reading outcomes.Read full original descriptionShow less
Effects of Optokinetic Stimulation Without a Reading Task in Patients With Hemianopic Alexia
The goal of this clinical trial is to investigate whether optokinetic stimulation delivered without a reading task can improve reading performance in adults with post-stroke hemianopic alexia. The main question it aims to answer is: does optokinetic stimulation without a reading task improve reading speed more than optokinetic stimulation with a reading task? Optokinetic stimlation with a reading task is considered the standard rehabilitation. These two conditions will be administered according to a randomized crossover design to determine wether the presence or absence of a reading task influences reading outcomes.
Participants will
* receive 4 weeks of optokinetic stimulation without a reading task and 4 weeks of optokinétic stimulation with a reading task, with the order of these two interventions determined by randomization, * undergo assesments of reading performance, oculomotor behavior, visual field and rehabilitation tolerability before and after each intervention period, * undergo a follow-up assesment 1 month after completion of the interventions.
Inclusion: Time since lesion > 1 month; Diagnosis of homonymous hemianopia post-stroke without macular sparing; Reading complaint and/or reading impairment; Proficiency in reading French; Agreed to give informed consent; Afiliated with national health insurance.
Exclusion: Reading disorder prior to the stroke (dyslexia); History of neurological or psychiatric disorders; Visual impairment of peripheral origin (i.e., related to damage to the structures of the eye or the optic nerve); Instability of reading impairment; Major cognitive that would limit the ability of the patient to participate in the study (unilateral spatial neglect, simultanagnosia, comprehension disorder, oral expression disorder); Uncorrected visual acuity deficit; Instability of homonymous hemianopia.
