BACKGROUND
P300 event-related potential has been used as an instrument to establish the diagnosis of several disorders as well as to assess therapeutic outcomes.
AIM
to investigate the relationship between stuttering amelioration and cerebral activity.
METHOD
P300 event-related potentials were obtained in three adult males, all stutterers, aged 20 to 31 years, pre and post-treatment, verifying changes in wave amplitude and latency between waves.
RESULTS
results indicate a significant positive correlation between the reduction in the percentage of stuttered syllables and the improvement in wave amplitude for the right ear.
CONCLUSION
stutterers can exhibit different patterns of interhemispheric activity with a tonal P300 task after undergoing a fluency-enhancing program.
背景
P300事件相关电位已被用作一种工具来确立多种疾病的诊断以及评估治疗效果。
目的
研究口吃改善与大脑活动之间的关系。
方法
对三名年龄在20至31岁之间的成年男性口吃者在治疗前和治疗后进行P300事件相关电位检测，验证各波之间的波幅和潜伏期变化。
结果
结果表明，口吃音节百分比的降低与右耳波幅的改善之间存在显著正相关。
结论
口吃者在接受流畅性增强训练后，在音调P300任务中可表现出不同的半球间活动模式。
