动态和静态手动作观察疗法对脑卒中慢性非流畅性失语的效果比较

Effect of Dynamic or Static Hand Action Observation on Chronic Non-fluent Aphasia after Stroke

目的比较基于非目标导向的动态视频和静态动作图片观察对慢性非流畅性失语症脑卒中患者言语功能的影响。方法2016年1月至2018年12月,脑卒中非流畅性失语患者30例随机分为两组,对照组(n=15)予以非目标导向手动作图片和动词复述,试验组(n=15)予非目标导向手动作视频和动词复述,共4周。治疗前及治疗后每周末,采用西方失语症成套测验(WAB)进行测试。结果两组失语商均随时间而改善(F>32.922,P<0.001),各时间点两组间均无显著性差异(t<0.699,P>0.05),时间和分组交互效应显著(F=6.398,P<0.001),试验组失语商增加更多。结论动态手动作观察可能较静态观察更有利于脑卒中慢性非流畅性失语患者言语功能的恢复。

Objective To compare the effects of observation to non-goal-oriented hand actions with video or pictures on speech recovery in stroke patients with chronic non-fluent aphasia.Methods From January,2016 to December,2018,30 patients with non-fluent aphasia after stroke were randomly divided into two groups.The control group(n=15)repeated the verbs after watching picture,and the experimental group(n=15)repeated the verbs after watching videos,for four weeks.They were assessed with Western Aphasia Battery(WAB)before treatment and every week after treatment.Results Aphasia quotient(AQ)increased with time(F>32.922,P<0.001),but no significant difference was found between two groups at any time points(t<0.699,P>0.05).The interactive effect between time and group was significant(F=6.398,P<0.001),which suggested that AQ increased more in the experimental group than in the control group.Conclusion For non-goal-oriented hand action observation,video observation maybe promote speech recovery in stroke patients with chronic non-fluent aphasia.
