These findings suggest that low-tech VSDs have an impact on the manner and extent to which a person with aphasia and a communication partner contribute to conversational interactions involving information transfer.
Treatment with ACTION resulted in better production of finite verbs. The effects generalised to spontaneous speech. Most importantly, it was shown that communication in daily life improved.
Integrating technology and targeted treatment to improve narrative production in aphasia: A case study
Conclusions: Results indicate that this combined approach may be helpful in improving the connected speech of even chronic and severely non-fluent speakers. The characteristics of this aphasic speaker that might have contributed to this outcome, and the limitations of this study, are considered.
Outcomes & Results: The individual with aphasia made positive changes in word fluency, Correct Information Units and Type-Token Ratio.
Conclusions: These findings, while preliminary in nature, show how the authentic use of language in structured reciprocal interactions such as teaching may improve language. A reciprocal teaching environment carries with it the expectation that at least one participant have an intent to participate as an expert in order to convey information to novices. We speculate that the combination of reciprocal interaction and the intent to convey information, in this case in a unique manner, support improved language skills.
An Intention Manipulation to Change Lateralization of Word Production in Nonfluent Aphasia: Current Status
A review of recent aphasia literature indicates that both the left and right hemispheres participate, under various circumstances, in recovery of language and in treatment response. In chronic aphasias with large lesions and poor recovery of function, the right hemisphere is more likely to demonstrate prominent activity than in cases with small lesions and good recoveries. Extraneous activity during language tasks for aphasia patients may occur in both the left and right hemispheres. Right hemisphere activity during language in aphasia patients is likely to occur in structures homologous to damaged left hemisphere structures. When the left hemisphere is so damaged as to preclude a good recovery, recruitment of right-hemisphere mechanisms in the service of rehabilitation may be desirable. Hence a treatment with an intention manipulation (complex left-hand movement) was developed for nonfluent aphasia to assist in relateralization of language production. A review of existing evidence indicates that the intention manipulation adds value to naming treatments and helps shift lateralization of language production to right frontal structures. However, wholesale transfer of language function to the right hemisphere does not occur, and residual language knowledge in the left hemisphere also seems vital for relearning of word production. Further research is needed to understand fully the contribution of the intention manipulation to treatment response.
