[Purpose] The purpose of this study was to compare prefrontal activations during an added-purpose task with those during a single-purpose task using functional near-infrared spectroscopy. [Subjects] Six healthy right-handed adults were included in this study. [Methods] The participants were instructed to complete both added-purpose and single-purpose activities separately with each hand. The near-infrared spectroscopy probes were placed on the scalp overlying the prefrontal cortex, according to the International 10-20 system (Fz). Changes in the oxygenated hemoglobin and deoxygenated hemoglobin concentrations in the prefrontal cortex were measured during performance of the activities. We then compared the number of activation channels with significant increase in oxygenated hemoglobin, during added-purpose activity to single-purpose activity using both hands separately. [Results] A greater number of widespread activations were observed in the prefrontal cortex during the added-purpose task than during the single-purpose task. These results were noted with both right and left hands. [Conclusion] According to our findings, added-purpose activity can bring about more activation in the prefrontal cortex, which may provide occupational therapists with effective guides in therapeutic practice.
[目的]本研究旨在使用功能近红外光谱技术比较在附加目的任务期间与单一目的任务期间前额叶的激活情况。[对象]本研究纳入了6名健康的右利手成年人。[方法]参与者被要求用每只手分别完成附加目的和单一目的活动。根据国际10-20系统（Fz），将近红外光谱探头放置在前额叶皮质上方的头皮上。在活动进行期间测量前额叶皮质中氧合血红蛋白和脱氧血红蛋白浓度的变化。然后我们分别比较了使用双手进行附加目的活动与单一目的活动时，氧合血红蛋白显著增加的激活通道数量。[结果]与单一目的任务相比，在附加目的任务期间前额叶皮质中观察到更广泛的激活。左右手均出现了这些结果。[结论]根据我们的研究结果，附加目的活动可在前额叶皮质中带来更多激活，这可能为职业治疗师的治疗实践提供有效的指导。
