Occupational therapy often uses craft activities as therapeutic tools, but their therapeutic effectiveness has not yet been adequately demonstrated. The aim of this study was to examine changes in frontal midline theta rhythm (Fmθ) and autonomic nervous responses during craft activities, and to explore the physiological mechanisms underlying the therapeutic effectiveness of occupational therapy. To achieve this, we employed a simple craft activity as a task to induce Fmθ and performed simultaneous EEG and ECG recordings. For participants in which Fmθ activities were provoked, parasympathetic and sympathetic activities were evaluated during the appearance of Fmθ and rest periods using the Lorenz plot analysis. Both parasympathetic and sympathetic indices increased with the appearance of Fmθ compared to during resting periods. This suggests that a relaxed-concentration state is achieved by concentrating on craft activities. Furthermore, the appearance of Fmθ positively correlated with parasympathetic activity, and theta band activity in the frontal area were associated with sympathetic activity. This suggests that there is a close relationship between cardiac autonomic function and Fmθ activity.
职业治疗通常将手工艺活动用作治疗工具，但其治疗效果尚未得到充分证明。本研究的目的是检查手工艺活动期间额中线θ节律（Fmθ）和自主神经反应的变化，并探索职业治疗治疗效果背后的生理机制。为了实现这一目标，我们采用了一项简单的手工艺活动作为诱发Fmθ的任务，并同时进行脑电图（EEG）和心电图（ECG）记录。对于诱发了Fmθ活动的参与者，在Fmθ出现期间和休息期间使用洛伦兹图分析评估副交感神经和交感神经活动。与休息期间相比，副交感神经和交感神经指标均随着Fmθ的出现而增加。这表明通过专注于手工艺活动可以实现放松专注状态。此外，Fmθ的出现与副交感神经活动呈正相关，额叶区域的θ波段活动与交感神经活动相关。这表明心脏自主神经功能与Fmθ活动之间存在密切关系。
