旋律音调疗法治疗脑卒中后非流畅性失语的效果

目的 观察旋律音调疗法对脑卒中后非流畅性失语的临床康复疗效以及脑功能改变。方法 2017年3月至2019年8月,选取本院脑卒中后非流畅性失语患者40例,随机分为对照组和音乐组各20例,两组均接受言语治疗,音乐组在此基础上接受以旋律音调疗法为主的音乐治疗。治疗前和治疗4周后,采用中国康复研究中心汉语标准失语症检查表(CRRCAE)评定其听理解、复述、阅读、命名。两组各选3例患者,治疗前后行静息态fMRI,比较大脑半球局部一致性(ReHo)。结果 治疗后,对照组听理解(名词、动词、句子)、复述(名词、动词)、阅读(名词)和命名(动作说明)评分提高(t > 2.221, P < 0.05),音乐组听理解(名词、动词、句子)、复述(名词、动词、句子)、阅读(名词、动词)和命名(名词、动作说明)评分提高( t > 2.179, P < 0.05)。治疗前后差值比较,音乐组复述(名词、动词)评分增加更多( t > 2.299, P < 0.05),阅读(句子)评分有增加的趋势。治疗后,患者静息状态下左侧小脑、颞枕区的ReHo增强,双侧额叶、颞叶皮质ReHo降低。 结论 在言语训练基础上,联合旋律音调疗法可进一步改善脑卒中后非流畅性失语患者的言语功能,特别在句子阅读和单词复述方面。ReHo改变可能与脑损伤后神经修复有关。

Effect of Melodic Intonation Therapy on Nonfluent Aphasia after Stroke

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.
