目的

探讨利用不同方式的经颅直流电刺激(tDCS)作用于右侧小脑外侧联合语言训练,对脑卒中后失语症(PSA)患者语言功能的影响。

方法

选取自2022年2月至2024年7月于深圳市龙岗区人民医院康复医学科住院的18例PSA患者进行自身前后对照试验。所有患者进行3个阶段的治疗,分别为1周tDCS伪刺激+语言训练,1周tDCS阳极刺激右侧小脑外侧+语言训练,1周tDCS阴极刺激右侧小脑外侧+语言训练,3个阶段顺序不一,每个阶段间隔1 d。在每个阶段前后对患者进行图命名测验和听觉词图匹配测验。分析每个阶段治疗前后的测验准确率变化,以及不同tDCS方式刺激后准确次数提高程度的差异。

结果

tDCS阳极刺激右侧小脑外侧时,治疗前后图片命名准确率和听理解的提高程度显著高于伪刺激,差异均有统计学意义(P<0.05);而tDCS阴极刺激右侧小脑外侧时,提高程度与伪刺激比较,差异无统计学意义(P>0.05)。

结论

tDCS阳极刺激右侧小脑外侧可以提高PSA患者图命名和听理解能力的改善程度。

Objective

To investigate the effects of different modes of transcranial direct current stimulation (tDCS) on the lateral right cerebellum combined with language training on the language function of patients with post-stroke aphasia (PSA).

Methods

The study was designed with before-after study in the same individuals. A total of 18 patients with PSA who were hospitalized in the Rehabilitation Medicine Department of Longgang District People's Hospital of Shenzhen from February 2022 to July 2024 were selected, they had to complete three stages of treatment, namely 1 week of tDCS pseudostimulation+language training, 1 week of tDCS anodic stimulation of the right lateral cerebellum+language training, and 1 week of tDCS cathodic stimulation of the right lateral cerebellum+language training. The sequence of the 3 phases varies, with each phase spaced 1 d apart. Patients are given a diagram naming test and an auditory word diagram matching test before and after each stage. The changes in test accuracy before and after treatment at each stage, as well as the difference in the degree of improvement of accuracy after stimulation by different tDCS modes were analyzed.

Results

When tDCS anodic stimulates the right lateral cerebellum, the improvement of image naming and auditory comprehension accuracy before and after treatment was significantly higher than that of pseudo-stimulation (P<0.05),while cathodal tDCS applied to the right lateral cerebellum showed no significant difference in improvement compared with sham stimulation (P>0.05).

Conclusion

Anodal tDCS stimulation of the right lateral cerebellum can enhance the improvement degree of picture naming and auditory comprehension abilities in PSA patients.
