Effect of Trans Cranial Magnetic Stimulation in Management of Dysphasia, A Systematic Review

Abstract

Aphasia is the most disabling functional defect after ischemic stroke, it affects more than a third of all stroke victims. Effective therapeutic strategies are needed to treat aphasic patients, treatments which can benefit people with aphasia include: intensive speech and language therapy (SLT), medications, stem cell transplantation and Transcranial Magnetic Stimulation. Novel techniques, such as methods of delivering cortical brain stimulation to modulate cortical excitability, such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), are just beginning to be explored. Types of TMS, depending on the mode of stimulation, includes: Single or paired pulse TMS, Repetitive TMS (rTMS) {slow rTMS (1Hz) and fast rTMS (5, 10, or 20 Hz)} and Intermittent Theta burst stimulation which is a patterned form of rTMS.
