About
Stroke is currently an important cause of death and disability among adults worldwide, with acute ischemic stroke being the most common type of stroke, accounting for 69.6% -72.8% of new strokes in China. The time division of the acute phase generally refers to the onset time within 1-2 weeks. About 21-38% of stroke patients have post-stroke aphasia. Post stroke aphasia is usually an acquired language disorder caused by damage to the language functional areas of the dominant hemisphere, characterized by varying degrees of impairment in some or all language functions, including speaking, listening and understanding, paraphrasing, naming, reading, and calligraphy abilities. Rehabilitation treatment for cerebral infarction should be done early rather than late. Based on this, this study aims to explore transcranial magnetic stimulation therapy for post-stroke aphasia patients in the acute phase. By regulating the balance of cortical excitability on both sides of the healthy and affected areas, early speech function rehabilitation can be achieved, which is necessary for improving the quality of life of post-stroke aphasia patients
Full description
Post stroke aphasia (PSA) is an acquired communication disorder caused by brain injury, characterized by various functional impairments such as self speech, repetition, naming, auditory comprehension, reading, and writing. PSA is one of the serious sequelae of stroke, which seriously affects the quality of life of patients. Early intervention in speech therapy can to some extent restore patients' functional communication abilities. Transcranial magnetic stimulation (TMS) is currently the most widely used non-invasive therapy. TMS can generate a magnetic field through the principle of magnetoelectric conversion, which can penetrate the skull and generate a super threshold current, allowing neurons in the target brain area to discharge. High frequency rTMS (generally frequency>5HZ) is usually applied to the affected side, aiming to improve aphasia symptoms by directly promoting the excitability of the affected cortex.
The rehabilitation treatment for PSA patients often stabilizes within a few months after stroke, and early intervention may maximize potential benefits. At present, research on high-frequency rTMS is mostly limited to the subacute or chronic phase. Therefore, this study aims to explore a safe and effective TMS treatment method during the acute phase.
