The therapeutic structure of occupational therapy (OT) includes groups. Although the presence of others is expected to be relaxing due to the social buffering effect and the tend and befriend theory, it has not been sufficiently validated in accordance with the therapeutic structure of OT. The aim of this study was to investigate the electrophysiological evidence for the effectiveness of parallel groups and states of concentration on craft activities used in OT.
Thirty healthy young adults were used as controls to measure EEG and autonomic activity during craft activities in three conditions: alone, parallel, and nonparallel. EEG was analyzed using exact low-resolution electromagnetic tomography, and autonomic activity was analyzed using Lorenz plot analysis.
Parasympathetic activity was significantly higher in the parallel condition than in the alone condition. A significant negative correlation was found between current source density and parasympathetic activity in the region centered on the right insular cortex in the α1 band, and functional connectivity in regions including the anterior cingulate cortex and insular cortex was associated with autonomic activity.
Craft activities that occurred during frontal midline theta rhythm also increased parasympathetic activity. The results suggest that the parallel groups used in OT and the intensive state of craft activities induce a social buffering effect that increases parasympathetic activity despite the absence of physical contact or social support. This provides evidence for the effectiveness of the therapeutic structure of occupational activities and groups in OT.
职业治疗（OT）的治疗结构包括小组活动。尽管由于社会缓冲效应和倾向友好理论，他人的存在预计会令人放松，但根据 OT 的治疗结构，这一点尚未得到充分验证。本研究旨在调查在 OT 中使用的手工艺活动的平行小组和专注状态对其有效性的电生理证据。
使用 30 名健康的年轻成年人作为对照，在三种条件下（单独、平行和非平行）测量手工艺活动期间的 EEG 和自主活动：单独、平行和非平行。使用精确低分辨率电磁断层扫描分析 EEG，使用洛伦兹图分析分析自主活动。
在平行条件下，副交感神经活动明显高于单独条件。在α1 波段，右侧脑岛皮层中心区域的电流源密度与副交感神经活动呈显著负相关，包括前扣带皮层和脑岛在内的区域的功能连接与自主活动相关。
在前额中线 theta 节律期间进行的手工艺活动也会增加副交感神经活动。结果表明，OT 中使用的平行小组和专注于手工艺活动的状态会引起社会缓冲效应，尽管没有身体接触或社会支持，也会增加副交感神经活动。这为 OT 中职业活动和小组的治疗结构的有效性提供了证据。
