pBFS-guided cTBS Over the Inferior Frontal Gyrus for Aphasia After Ischemic Stroke

Официальное название

Personalized Brain Functional Sector-guided Continuous Theta Burst Stimulation Therapy Targeting at the Inferior Frontal Gyrus for Aphasia After Ischemic Stroke: a RCT

Обзор

The objective of this trial is to evaluate the effectiveness and safeness of continuous Theta Burst Stimulation (cTBS) over the right Inferior Frontal Gyrus (IFG), guided by personalized Brain Functional Sector (pBFS) technology, on language function recovery in patients with post-ischemic stroke aphasia.

Подробное описание

Increasing evidence suggests that rTMS has been effective in treating various psychological and neurological diseases, including treating post-stroke symptoms. Using the personalized brain functional sectors (pBFS) technique, investigators could precisely identify individualized brain functional networks and the personalized language-related stimulation site based on the resting-state functional MRI data. The current study proposes to conduct a double-blinded, randomized and parallel controlled design trial, to investigate the efficacy and safety of pBFS-guided personalized rTMS intervention in post-stroke aphasic patients.

Subjects will be randomly assigned to the following two groups: active continuous TBS (cTBS) group, or a sham control group. The allocation ratio will be 1:1. The stimulation protocol consisted of a 3-week treatment, with five consecutive days each week (totally 15 day-treatment) . The stimulation procedure will be assisted with real-time neuronavigation to ensure its precision.

Вмешательства

• Устройство active continuous Theta Burst Stimulation
  Each patient will receive two 600-pulse cTBS stimulations per day, parted by a 15-minute rest period (a total of 1200 pulses daily), for 3-week treatment, with 5 consecutive days each week.
• Устройство sham continuous Theta Burst Stimulation
  Each patient will receive two sham 600-pulse cTBS stimulations per day, parted by a 15-minute rest period (a total of 1200 pulses daily), for 3-week treatment, with 5 consecutive days each week.
