For children with attention deficit/hyperactivity disorder (ADHD), a reduction of inattention by biofeedback has been shown in several studies. As evidenced by previous reports, biofeedback (BFB) with virtual reality (VR) allows for controlling distractors, providing an environment that captures participants' attention. The purpose of this study was to evaluate the effects of hemoencephalographic (HEG) BFB with VR in treating deficits in vigilance (assessed using the short form of the Mackworth Clock Task), visual search (the Visual Search Task), and divided attention (Multitasking Test) among children with ADHD. Data subjected to analysis were collected from 87 participants aged 9-15 years. Children were assigned to one of three groups (standard 2D BFB in the lab, VR BFB with a limited visual scene, VR BFB with a complex visual scene) and were subjected to ten HEG BFB sessions. Children in the VR BFB groups exhibited a bigger regional cerebral blood oxygenation slope during BFB and better performance in cognitive tests following the experiment compared to children in the 2D BFB group. The data obtained suggest that HEG BFB with VR may have a more beneficial effect in treating attention deficits compared to standard 2D HEG BFB. We believe that the strong effects of HEG BFB with VR stem from the increased commitment and motivation in individuals, rather than from manipulation with regard to visual scene complexity.
对于患有注意力缺陷多动障碍（ADHD）的儿童，几项研究表明生物反馈可减少注意力不集中。如先前的报告所述，虚拟现实（VR）生物反馈（BFB）可控制干扰因素，提供吸引参与者注意力的环境。本研究旨在评估基于脑电（HEG）的 VR BFB 治疗 ADHD 儿童警觉性（使用 Mackworth 时钟任务短表评估）、视觉搜索（视觉搜索任务）和注意力分散（多重任务测试）缺陷的效果。分析的数据来自 87 名 9-15 岁的参与者。将儿童分为三组（实验室标准 2D BFB、具有有限视觉场景的 VR BFB、具有复杂视觉场景的 VR BFB），并接受 10 次 HEG BFB 治疗。与 2D BFB 组的儿童相比，VR BFB 组的儿童在 BFB 期间表现出更大的区域脑血氧饱和度斜率，并且在实验后认知测试中的表现更好。研究结果表明，与标准的 2D HEG BFB 相比，基于 HEG 的 VR BFB 可能对治疗注意力缺陷有更有益的效果。我们认为，基于 HEG 的 VR BFB 的强烈效果源自于个体的更高承诺和积极性，而不是来自于视觉场景复杂性的操作。
