Studies on whether mental practice (MP) in patients with stroke using action observation training (AOT) is effective in improving physical performance are still insufficient. To examine the effects of MP on both occupational performance and motor function to complement studies relevant to MP with AOT.
Subjects of this study were 3 individuals who were diagnosed with stroke. We used an A-B-A study design with follow-up evaluation, which is a type of reversal single experimental research design. A total of 20 experimental sessions were conducted. To assess the long-term effect of MP with AOT, follow-up baseline measurements were made after 2 weeks without MP. Three-dimensional motion analysis and electromyography were conducted during each of the 20 sessions. The Motor Activity Log and Assessment of Motor and Process Skills were measured 3 times: in the pre-MP phase, the post-MP phase, and the 2-week follow-up phase.
Occupational performance improved after intervention in all 3 subjects when applying an MP task using AOT. All subjects showed improvement of motor functions, including smoothness of movement, agonistic muscle activation, and co-ordination. The treatment effect continued after 2 weeks.
MP using AOT in patients with stroke is an effective treatment protocol to improve occupational performance and motor function. Thus, MP using AOT may be applicable for treating stroke patients with stroke not only while they are in the hospital but also at home or in the community.
关于中风患者采用动作观察训练（AOT）进行心理练习（MP）是否能有效改善身体机能的研究仍不充分。为了研究MP对职业表现和运动功能的影响，以补充与AOT相关的MP研究。
本研究的受试者为3名被诊断为中风的个体。我们采用了带有随访评估的A - B - A研究设计，这是一种反转单实验研究设计。总共进行了20次实验。为了评估MP与AOT结合的长期效果，在停止MP两周后进行随访基线测量。在20次实验中的每次实验期间都进行了三维运动分析和肌电图检查。对运动活动日志以及运动和过程技能评估进行了3次测量：在MP前阶段、MP后阶段和2周随访阶段。
在应用使用AOT的MP任务后，所有3名受试者的职业表现均在干预后得到改善。所有受试者的运动功能都有所改善，包括动作流畅性、主动肌激活和协调性。治疗效果在2周后仍持续存在。
中风患者采用AOT进行MP是改善职业表现和运动功能的有效治疗方案。因此，采用AOT的MP不仅适用于中风患者在住院期间的治疗，也适用于在家中或社区的治疗。
