The Efficacy of Navigated Perilesional Repetitive Transcranial Magnetic Stimulation on Post-Stroke Visual Field Defects
In Brief
A clinical study evaluating High frequency repetitive transcranial magnetic stimulation (rTMS) and Sham stimulation for Visual Fields Hemianopsia and 2 related conditions. Completed, enrolled 32 participants across 1 site.
Detailed Summary
Visual field defects (VFD) usually do not show improvement beyond 12 weeks from onset. Plasticity occurs in areas of residual vision (ARV) at the visual field which are the functional counterpart of partially damaged brain regions at the areas around brain lesion. Few treatment options are currently available for post-stroke VFD. In this pilot study, the effect of repetitive transcranial magnetic stimulation (rTMS) applied to these areas on VFD in patients with cortical infarction will be studied. Patients will be divided into two groups; an active group which will receive active stimulation and a sham group which will receive placebo stimulation through a sham coil.
Study Details
Timeline
Interventions
10hz, 20 seconds intertrain interval, 40 pulses per train with a total of 1000 pulse per session given at 100% of motor threshold. A total of 16 sessions will be given to each patient.
A sham coil will be used that is shielded so that it produces sounds and sensations similar to the active coil but does not produce therapeutic effects. 10hz, 20 seconds intertrain interval, 40 pulses per train with a total of 1000 pulse per session given at 100% of motor threshold. A total of 16 sessions will be given to each patient.
