摘要
失语症作为脑损伤后的常见语言障碍，严重影响患者的生活质量，传统语言训练虽有一定疗效，但效果有限。本研究旨在探讨经颅直流电刺激（tDCS）辅助语言训练对失语症患者的改善效果。研究选取40例失语症患者，随机分为实验组和对照组，实验组接受tDCS联合语言训练，对照组仅进行语言训练，干预周期为4周。通过标准化语言评估量表考察患者在命名、复述、听理解等方面的变化。结果显示，实验组在命名准确率和听理解能力上的提升显著高于对照组（p0.05），且干预后效果具有持续性。这一发现表明，tDCS能够增强大脑皮层兴奋性，促进神经可塑性，从而提高语言训练的效果。本研究的创新点在于首次系统验证了tDCS与语言训练结合的协同效应，并为失语症康复提供了新的干预策略，具有重要的临床应用价值。关键词：失语症；经颅直流电刺激（tDCS）；语言训练；命名准确率；听理解能力
Observation of the Efficacy of tDCS-Assisted Language Training in Improving Aphasia
Abstract
Aphasia, as a common language disorder following brain injury, significantly impairs patients' quality of life. While traditional language training has some therapeutic effects, its outcomes are limited. This study aimed to investigate the improvement effects of transcranial direct current stimulation (tDCS) combined with language training on patients with aphasia. A total of 40 aphasic patients were recruited and randomly divided into an experimental group and a control group. The experimental group received tDCS in conjunction with language training, whereas the control group underwent language training alone. The intervention lasted for four weeks. Changes in naming, repetition, and auditory comprehension were assessed using standardized language evaluation scales. The results indicated that the experimental group showed significantly greater improvements in naming accuracy and auditory comprehension compared to the control group (p0.05), with sustained effects post-intervention. This finding suggests that tDCS can enhance cortical excitability and promote neuroplasticity, thereby improving the efficacy of language training. The novelty of this study lies in its systematic validation of the synergistic effect of combining tDCS with language training, providing a new intervention strategy for aphasia rehabilitation with significant clinical application value.
