Repetitive Transcranial Magnetic Stimulation for Post-Stroke Visual Field Defects

NCT04021160 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 32

No results posted yet for this study

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.

Conditions

  • Visual Fields Hemianopsia
  • Stroke, Ischemic
  • Stroke Hemorrhagic

Interventions

DEVICE

High frequency repetitive transcranial magnetic stimulation (rTMS)

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.

DEVICE

Sham stimulation

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.
