Stroke has become the leading cause of disability and death in humans, and the incidence has increased year by year. Traditional treatment methods mainly include thrombolytic therapy, dehydration, reduction of intracranial pressure, nutritional nerves, and surgical treatment. Repetitive transcranial magnetic stimulation is a new type of electrophysiological technique that has been widely used in clinical practice in recent years. This paper summerized the research progress of different factors in the treatment of lower limb motor dysfunction after stroke transcranial magnetic stimulation, to found reference for its effectiveness and safety in the treatment of stroke.
