Brief Summary

A randomized, controlled, subject and rater-blind, exploratory clinical trial to evaluate the safety and efficacy of repetitive transcranial magnetic stimulation for improvement of upper extremity function after stroke.

Detailed Description

Some studies related to rTMS for the recovery of motor function (upper and lower extremity functions) after stroke are being conducted, and the clear mechanism has not been elucidated. It is known that function is restored through various neurophysiological changes.

However, there are not many studies on rTMS in the chronic stroke period, 3 months after the onset of stroke recovery, which is slow, and among them, there is no established standard for which part of the brain should be stimulated for treatment.

Recently, techniques for finding brain regions that are activated when performing a specific action through an imaging technique called fMRI (Functional Magnetic Resonance Imaging) are being used in various fields.

Based on the idea in this regard, recent studies have been conducted that the effect of rTMS treatment is better than the existing method when fMRI is used to identify the brain regions involved in the movement of the upper and lower extremities.

The purpose of this study is to evaluate the safety and efficacy on upper extremity function after stroke using fMRI and rTMS.

Sham groupShamSham group: shame rTMS( sound mode) is applied over the M1 cortex of the injured hemisphere which is the site that caused the largest visible twitch in the participant's thumb when stimulation is applied
rTMS over the M1 cortex of the injured hemisphere localized by motor action potentialrTMSExperimental A group : rTMS was administered by trained physicians over the M1 cortex of the injured hemisphere aiming at the site that caused the largest visible twitch in the participant's thumb.
rTMS over the specific site of the injured hemisphere localized by fMRIrTMSExperimental B group : rTMS was administered by trained physicians over the specific site which is after checking the brain site activated during finger tapping during fMRI imaging, target coordinates are set based on the 10-20 EEG system coordinate system in the taken MRI image.
