Research Progress of Melodic Intonation Therapy and Non-invasive Brain Stimulation in Aphasia after Stroke (review) / 中国康复理论与实践

ABSTRACT

@#The neuromechanism of language function recovery in patients with aphasia after stroke is still unclear. It is supported that the language function of aphasia after extensive damage of left hemisphere mainly recovered through activating the right hemisphere of ho-mologous regions to improve the function of speech. Melodic intonation therapy (MIT) can be achieved by melody tone and left hand clap to activate the right hemisphere of the frontal temporal lobe, which is particularly applicable to improve language function of non-fluent aphasia patients with large left hemisphere lesion. Non-invasive brain stimulation techniques (NBS) changes brain activity through stimulat-ing affected or contralateral side, which has been used to facilitate language functional recovery after stroke. Excitatory transcranial stimula-tion on the right hemisphere homology combined with melodic intonation therapy can promote language recovery of patients with extensive damage of left hemisphere after stroke. It is valuable to combine traditional speech training with MIT and NBS to activate related language functional areas to maximum improvement of language recovery after stroke.
