Previous studies suggest that parasympathetic functions support sensory behaviours. However, the relationship between sensory behaviours and parasympathetic functions remain inconclusive and inconsistent among children with and without attention-deficit hyperactivity disorder (ADHD). This research aims to examine the sensory behaviours and resting parasympathetic functions among children with and without ADHD. We compared sensory behaviours and baseline parasympathetic functions of 64 participants, with 42 typically developing and 24 ADHD male children aged 7-12 years. Sensory behaviours were evaluated using the sensory profile. Baseline parasympathetic functions were indexed using the normalized unit of heart rate variability high-frequency bands (HF n.u.). Children underwent an experimental protocol consisting of watching a silent cartoon movie while HF n.u. is continuously monitored, within a controlled environment. The results of this research showed significantly lower HF n.u. ((64) = 7.84, < 0.01) and sensory processing total score ((64) = 14.13 = < 0.01) among children with ADHD compared to their typically developing peers. Likewise, a significant moderate positive correlation ( = 0.36, < 0.05) was found between the HF n.u. and sensory profile total scores among children with ADHD. Children with ADHD have significantly lower resting state parasympathetic functions compared to their typically developing peers.
先前的研究表明，副交感神经系统的功能支持感官行为。然而，在患有和不患有注意缺陷多动障碍（ADHD）的儿童中，感官行为和副交感神经功能之间的关系仍不确定且不一致。本研究旨在检查患有和不患有 ADHD 的儿童的感官行为和静息副交感神经功能。我们比较了 64 名参与者的感官行为和基础副交感神经功能，其中 42 名是发育正常的儿童，24 名是患有 ADHD 的男性儿童，年龄在 7-12 岁之间。感官行为使用感官评估量表进行评估。基础副交感神经功能使用心率变异性高频带（HF n.u.）的归一化单位进行指标。儿童在受控环境中观看无声卡通电影时，连续监测 HF n.u.，同时进行实验方案。研究结果表明，与发育正常的同龄人相比，患有 ADHD 的儿童的 HF n.u.（(64) = 7.84，<0.01）和感官处理总分（(64) = 14.13，<0.01）显著降低。同样，在患有 ADHD 的儿童中，HF n.u.与感官评估量表总分之间存在显著的中度正相关（ = 0.36，<0.05）。与发育正常的同龄人相比，患有 ADHD 的儿童的静息副交感神经功能显著降低。
