    Outcomes

    Primary Outcome Measures

    Change in the Western Aphasia Battery scores
    The first four subsets of the WAB (Spontaneous Speech, Auditory verbal comprehension, Repetition, Naming and word finding) will be used to evaluate the participants' language ability impairments. A Chinese adapted version of WAB will be used. The scores from all four subsets will be calculated as an Aphasia Quotient (ranging from 0 to 100), with lower Aphasia Quotients indicating poorer language abilities.

    Secondary Outcome Measures

    Change in the Western Aphasia Battery scores
    The first four subsets of the WAB (Spontaneous Speech, Auditory verbal comprehension, Repetition, Naming and word finding) will be used to evaluate the participants' language ability impairments. A Chinese adapted version of WAB will be used. The scores from all four subsets will be calculated as an Aphasia Quotient (ranging from 0 to 100), with lower Aphasia Quotients indicating poorer language abilities.
    Boston Diagnostic Aphasia Examination Severity Ratings
    The Boston Diagnostic Aphasia Examination (BDAE) Severity Ratings is a clinical tool used to evaluate the severity and type of aphasia in individuals. The assessment includes four domains: communication abilities, language content, speech sound production and response abilities.BDAE severity ratings range from level 1 to level 5, with higher scores indicating more severe aphasia.
    Token test
    The Token Test is a language assessment tool used to evaluate a person's ability to understand spoken language and follow instructions. Each correct response in each task is awarded one point, typically. Different point values may be assigned based on the complexity of the task. The total score is calculated by adding up the accumulated scores across all tasks. The total scores range from 0 to 36, with higher scores indicating better language abilities.
    Chinese-version Stroke and Aphasia Quality of Life Scale 39-generic version (SAQOL-39g)
    The SAQOL-39g is a quality of life assessment tool that is used to evaluate the impact of stroke and aphasia on a patient's quality of life. It consists of 39 items that cover a range of domains related to the patient's quality of life, such as communication, physical functioning, mood, and social support. The items are rated on a 5-point Likert scale ranging from "not at all" to "very much", with higher scores indicating better quality of life.

    5. Study Description

    Brief Summary
    The objective of this trial is to evaluate the effectiveness and safeness of intermittent Theta Burst Stimulation (iTBS) over the left Superior Temporal Gyrus (STG), guided by personalized Brain Functional Sector (pBFS) technology, on language function recovery in patients with post-ischemic stroke aphasia.
    Detailed Description
    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 Sector (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 sham controlled 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 intermittent TBS (iTBS) group, or a sham control group. The allocation ratio will be 1:1. The stimulation protocol consists 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.
