Attention-deficit/hyperactivity disorder (ADHD) is the most common neuropsychiatric disorder in schoolchildren. ADHD diagnoses are generally made based on criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. The diagnosis is made clinically based on observation and information provided by parents and teachers, which is highly subjective and can lead to disparate results. Considering that hyperactivity is one of the main symptoms of ADHD, the inaccuracy of ADHD diagnosis based on subjective criteria necessitates the identification of a method to objectively diagnose ADHD.
In this study, a medical chair containing a piezoelectric material was applied to objectively analyze movements of patients with ADHD, which were compared with those of patients without ADHD. This study enrolled 62 patients-31 patients with ADHD and 31 patients without ADHD. During the clinical evaluation, participants' movements were recorded by the piezoelectric material for analysis. The variance, zero-crossing rate, and high energy rate of movements were subsequently analyzed.
The results revealed that the variance, zero-crossing rate, and high energy rate were significantly higher in patients with ADHD than in those without ADHD. Classification performance was excellent in both groups, with the area under the curve as high as 98.00%.
Our findings suggest that the use of a smart chair equipped with piezoelectric material is an objective and potentially useful method for supporting the diagnosis of ADHD.
注意力缺陷多动障碍（ADHD）是学龄儿童中最常见的神经精神疾病。ADHD 的诊断通常基于《精神障碍诊断与统计手册》第五版的标准。该诊断是基于临床观察和家长及教师提供的信息做出的，具有高度主观性，可能导致结果不一致。由于多动是 ADHD 的主要症状之一，因此基于主观标准的 ADHD 诊断不准确，需要找到一种客观诊断 ADHD 的方法。
本研究应用内置压电材料的医疗椅客观分析 ADHD 患者的运动情况，并与无 ADHD 患者的运动情况进行比较。该研究共纳入 62 名患者，其中 31 名患有 ADHD，31 名无 ADHD。在临床评估过程中，参与者的运动由压电材料记录进行分析。随后分析运动的方差、过零率和高能率。
结果表明，ADHD 患者的方差、过零率和高能率均显著高于无 ADHD 患者。两组的分类性能均优异，曲线下面积高达 98.00%。
我们的研究结果表明，使用配备压电材料的智能椅是一种客观且具有潜在应用价值的 ADHD 诊断支持方法。
