Overview
Brief Summary
The study aimed to figure out brain structural and functional reorganization evidence after repetitive transcranial magnetic stimulation through the method of neuroimaging brain network analysis, such as resting-state functional magnetic resonance imaging and diffusion tensor imaging.

Outcomes
Primary Outcomes
National Institutes of Health Stroke Scale (NIHSS)
Time Frame: Change from Baseline NIHSS at 1 month after real rTMS/sham rTMS
The investigators use National Institutes of Health Stroke Scale (NIHSS) to evaluate the participants' neural deficit after stroke. The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0. Higher NIHSS scores mean a worse outcome.
Barthel Index (BI)
Time Frame: Change from Baseline BI at 1 month after real rTMS/sham rTMS
The investigators use Barthel Index (BI) to evaluate the participants' activities of daily living after stroke. The BI consists of 10 questions that relate to degree of independence with activities of daily living, including toileting, bathing, eating, dressing, continence, transfers, and ambulation. The BI score is calculated by summing the response value to each of the 10 questions. The BI score ranges from 0 to 100. A patient scoring 0 points would be dependent in all assessed activities of daily living, whereas a score of 100 would reflect independence in these activities. A higher score is associated with a better outcome.
Fugl-Meyer Assessment Upper Limb (FMA-UL)
Time Frame: Change from Baseline FMA at 1 month after real rTMS/sham rTMS
The investigators use Fugl-Meyer assessment Upper Limb (FMA-UL) to evaluate the participants' motor function of upper limb. The FMA-UL is an ordinal scale that has 3 points for each item. A zero score is given for the item if the subject cannot do the task. A score of 1 is given when the task is performed partially and a score of 2 is given when the task is performed fully. The maximum score of FMA-UL is 66 and the minimum score is 0. Higher scores mean a better outcome.
Secondary Outcomes
