RESUMEN
Objective:To observe the effect of melodic intonation therapy combined with speech training on nonfluent aphasia after stroke, and the changes of brain function. Methods:From March, 2017 to August, 2019, 40 patients with nonfluent aphasia after stroke were randomly divided into control group (n = 20) and intensive group (n = 20). Both groups accepted routine speech training, and the intensive group accepted melodic intonation therapy in addition. They were assessed with China Rehabilitation Research Center Chinese Standard Aphasia Examination before and four weeks after treatment. Three patients from each group were examined with resting-state functional magnetic resonance imaging to observe the changes of regional homogeneity (ReHo) of cerebral hemisphere. Results:The scores of comprehension (noun, verb and sentence), repetition (noun and verb), read (noun) and naming (verb) increased in the control group (t > 2.221, P < 0.05), while it increased in comprehension (noun, verb and sentence), repetition (noun, verb and sentence), reading (noun and verb) and naming (noun and verb) in the intensive group (t > 2.179, P < 0.05). The scores of repetition (noun and verb) increased more in the intensive group than in the control group (t > 2.299, P < 0.05)， and the scores of reading (sentence) increased somehow. The ReHo in left cerebellum and temporal occipital area increased and the ReHo in bilateral frontal and temporal cortex decreased after treatment. Conclusion:Melodic intonation therapy based on speech therapy can promote the recovery of speech function for patients with nonfluent aphasia after stroke, especially in sentence reading and words repetition. The changes of the ReHo in resting state may associate with the neurological repairment after brain injury.
RESUMEN
@#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.
RESUMEN
@#Objective To observe the effect of Melodic Intonation Therapy on severe aphasia.Methods Additionally to the stimulus therapy,familiar songs were used in the treatment of listening,retelling and naming in 12 cases.Results The patients showed improvement in listening,retelling and naming.Conclusion Using familiar songs in the treatment can promote the recovery of aphasic patients.
