Evidence exists that the observation of actions performed by others enhance word retrieval and can be used in aphasia rehabilitation to treat naming impairments.
The aim of the present study was to assess to what extent action observation treatment may improve verb retrieval in chronic aphasics.
This was an observational study.
Patients were recruited from the Neurorehabilitation Centre of Ancona Hospital.
Six aphasic patients underwent an intensive language training to improve verb naming.
Language evaluation was carried out before and after the treatment. A rehabilitation therapy based on observation of actions was administered daily to each patient for two consecutive weeks. Four different rehabilitation procedures were adopted: 1) "observation of action performed by the examiner"; 2) "observation and then execution of action"; 3) "observation of videoclips of actions"; and, as a control condition; 4) "observation of action and execution of meaningless movement".
In four participants, a significant improvement in verb retrieval was found for the three experimental procedures (χ² (3)=75.212, P<0.0001), with respect to the control condition. No significant improvement was observed in the two patients with severe deficits in verb semantics (χ² (3)=0.592, P=0.892).
Action observation therapy may become a useful intervention strategy to promote verb retrieval in aphasic patients.
The observation of videoclips of actions may be an efficacious alternative approach to traditional rehabilitation programs for lexical deficits. This finding endorses the planning of innovative low-cost interventions in language rehabilitation.
有证据表明，观察他人执行的动作可以增强单词检索能力，并可用于失语症康复治疗，以治疗命名障碍。
本研究旨在评估动作观察治疗在多大程度上可以改善慢性失语症患者的动词检索能力。
这是一项观察性研究。
患者从安科纳医院神经康复中心招募。
六名失语症患者接受了强化语言训练，以改善动词命名。
在治疗前后进行语言评估。每天对每位患者进行基于动作观察的康复治疗，连续进行两周。采用了四种不同的康复程序：1）“观察检查者执行的动作”；2）“观察后执行动作”；3）“观察动作视频”；以及作为对照条件；4）“观察动作并执行无意义的运动”。
在四名参与者中，对于三种实验程序（χ²(3)=75.212，P<0.0001），动词检索均有显著改善，而对照条件下无显著改善。对于动词语义严重受损的两名患者（χ²(3)=0.592，P=0.892），未观察到显著改善。
动作观察治疗可能成为促进失语症患者动词检索的一种有用的干预策略。
动作视频的观察可能是传统词汇缺陷康复方案的一种有效替代方法。这一发现支持了语言康复中创新、低成本干预措施的规划。
