“…Preliminary studies (with 6 aphasic patients) showed that observation and execution of action might favor retrieval of action-related words in aphasic patients (Marangolo et al, 2010 ; Bonifazi et al, 2013 ). Duncan and his colleagues reported that observation of speech action (mouth, lip and tongue movement) followed by oral repetition of the words and phrases could improve repetition rather than general language function evaluated by AQ of WAB (Duncan et al, 2012 ).…”

“…To our knowledge, this is the first study reporting that hand action observation training could facilitate the improvement of general language function for aphasic patients. Although Duncan et al also adopted AQ to indicate general language recovery before and after treatment, they did not find significant improvement in AQ after speech action (mouth, lip, and tongue movement) observation training (Duncan et al, 2012 ). This may imply that hand action observation training is a better approach than speech/mouth action observation training for promoting general or comprehensive language function recovery for aphasic patients.…”

“…However, significant differences were not found between control (observe static faces and repeat the words and phrases) and experimental patients and were not found for general language measures pre- and post-therapy as evaluated by Aphasia Quotient (AQ) of western aphasia battery (WAB). The authors admitted in the article that failure of therapeutic effect to generalize to communication skills beyond repetition may indicate theoretical insufficiency or suboptimal implementation (Lee et al, 2010 ; Duncan et al, 2012 ).…”

Objective: To investigate the effect of hand action observation training, i.e., mirror neuron system (MNS) based training, on language function of aphasic patients after stroke. In addition, to reveal the tentative mechanism underlying this effect.Methods: Six aphasic patients after stroke, meeting the criteria, undergo 3 weeks' training protocol (30 min per day, 6 days per week). Among them, four patients accepted an ABA training design, i.e., they implemented Protocol A (hand action observation combined with repetition) in the first and third weeks and carried out Protocol B (static object observation combined with repetition) in the second week. Conversely, for the other two patients, BAB training design was adopted, i.e., patients took Protocol B in the first and third weeks and accepted Protocol A in the second week. Picture naming test, western aphasia battery (WAB) and Token Test were applied to evaluate the changes of language function before and after each week's training. Furthermore, two subjects (one aphasic patient and one healthy volunteer) attended a functional MRI (fMRI) experiment, by which we tried to reveal the mechanism underlying possible language function changes after training.Results: Compared with static object observation and repetition training (Protocol B), hand action observation and repetition training (Protocol A) effectively improved most aspects of the language function in all six patients, as demonstrated in the picture naming test, subtests of oral language and aphasia quotient (AQ) of WAB. In addition, the fMRI experiment showed that Protocol A induced more activations in the MNS of one patient and one healthy control when compared to Protocol B.Conclusion: The mirror neuron based therapy may facilitate the language recovery for aphasic patients and this, to some extent, provides a novel direction of rehabilitation for aphasia patients.

Mirror neurons that have properties of audio/visual-acuity play a key role in imitation of movement performance. Since speech is a collection of coordinated movements in the producing organs, observing and imitation of speech movements can stimulate these neurons. In addition, observing hand movements trigger some actions related to the verbal cortex in the network of mirror neurons. According to the hypothesis of mirror neurons, new therapeutic approaches, including IMITATE, have been proposed for patients with aphasia. In the present study, using the IMITATE programme, a new therapeutic approach called IMITATE-R was planned based on observation of oral movements, hand gestures, and imitation of oral movements. Afterward, the IMITATE and IMITATE-R methods were compared with each other on naming skills of two Persian people with aphasia. The results showed that the rate of benefit from each treatment in each client was proportional to its individual and linguistic characteristics; however, in both patients, the IMITATE-R method was more effective in improving the naming skill. The results of this study were aimed at confirming the hypothesis of mirror neurons and the use of methods are based on action-observation for the treatment of patients with aphasia.
