Aphasia as a common consequence of stroke, is an acquired neurologic communication disorder that can affect symbol language processing. Different types of intervention approaches have been introduced. Multimodal Communication Program (MCP) is a new augmentative alternative communication approach in chronic aphasia. The aim of this study was to investigate the effect of MCP on communication skills of patients with chronic aphasia.
This prospective, single subject, A-B-A design study was done during 2016 in Semnan, Iran. Participants were two patients with severe aphasia with a single left-hemisphere stroke. Three phases, including baseline, intervention and follow-up were administered. The patients received nine-hour intervention, over 10 working days.
Three different scores were calculated for each patient: verbal efforts, the frequency of each modality and the accuracy of switching between modalities and the reaction time. The frequency of verbal modality increased for both patients. They could switch between modalities more successfully than before the intervention. The results for the reaction time, however were challenging. The onset reaction time decreased for patient 1, and increased during switching between modalities, and patient 2 showed the opposite.
The MCP can improve the communication skills in patients with chronic post stroke aphasia. However, some factors, such as reduction of the patients' reaction time is probably related to the amount of allocated resources during intervention.
The trial was registered at IRCT center with ID: IRCT2016032325194N3.
The study was financed by Semnan University of Medical Sciences (Grant no.: A-10-333-3).
失语症是中风的常见后果，是一种后天性神经沟通障碍，会影响符号语言处理。已引入了不同类型的干预方法。多模态沟通计划（MCP）是一种针对慢性失语症的新型辅助替代沟通方法。本研究的目的是调查MCP对慢性失语症患者沟通技能的影响。
这项前瞻性、单受试者、A-B-A设计研究于2016年在伊朗塞姆南进行。参与者为两名因左侧半球单发性中风导致严重失语症的患者。研究分为三个阶段，包括基线、干预和随访。患者在10个工作日内接受了9小时的干预。
为每位患者计算了三个不同的分数：言语努力、每种模态的频率以及模态之间切换的准确性和反应时间。两名患者的言语模态频率均有所增加。他们在模态之间的切换比干预前更成功。然而，反应时间的结果颇具挑战性。患者1的起始反应时间缩短，但在模态切换期间增加，而患者2则相反。
MCP可改善中风后慢性失语症患者的沟通技能。然而，一些因素，如患者反应时间的缩短可能与干预期间分配的资源量有关。
该试验在伊朗临床试验注册中心注册，注册号为：IRCT2016032325194N3。
