Abstract

Peripheral body monitoring of autonomic nervous system (ANS) response has been routinely applied during infraslow fluctuation (ISF) neurofeedback training. This study hypothesized that ISF training has a distinct physiological effect on an individual that can be revealed by measuring autonomic function with peripheral biofeedback metrics that included heart rate variability (HRV), muscle tension, skin temperature, skin conductance, heart rate, respiration rate, and blood pressure. Methods. Thirty adults between the ages of 18 and 55, primarily with anxiety, were randomized into two groups: 20 in the experimental group and 9 in the control group. The experimental group completed 10 ISF neurofeedback training sessions while continuous monitoring of ANS changes was applied. The same process was completed for a control group that received one-channel sensorimotor rhythm (SMR) neurofeedback training. Results. Significant changes were seen in the skin conductance (p < .0001), electromyography (p = .01), very low frequency (p = .004), low frequency of HRV (p = .05) and blood pressure (systolic change p = .049) in the experimental group. No significant changes were seen in the control group. Conclusion. The study demonstrated that ISF neurofeedback training impacts the ANS as measured by peripheral biofeedback indicators.

亚慢频神经反馈对成人焦虑及相关疾病自主神经系统功能的影响

自主神经系统（ANS）反应的外周体监测已在次流波动（ISF）神经反馈训练中常规应用。这项研究假设，ISF训练对个体有明显的生理影响，这可以通过用外周生物反馈指标测量自主神经功能来揭示，这些指标包括心率变异性（HRV）、肌肉张力、皮肤温度、皮肤电导、心率、呼吸率和血压。方法。30名年龄在18岁至55岁之间的主要患有焦虑症的成年人被随机分为两组：实验组20人，对照组9人。实验组完成了10次ISF神经反馈训练，同时持续监测ANS的变化。接受单通道感觉运动节律（SMR）神经反馈训练的对照组也完成了同样的过程。后果实验组的皮肤电导（p<.0001）、肌电图（p=.01）、极低频率（p=.004）、HRV低频率（p=0.05）和血压（收缩压变化p=.049）发生了显著变化。对照组无明显变化。结论该研究表明，通过外周生物反馈指标测量，ISF神经反馈训练会影响ANS。

期刊介绍： NeuroRegulation is a peer-reviewed journal providing an integrated, multidisciplinary perspective on clinically relevant research, treatment, reviews, and public policy for neuroregulation and neurotherapy. NeuroRegulation publishes important findings in these fields with a focus on electroencephalography (EEG), neurofeedback (EEG biofeedback), quantitative electroencephalography (qEEG), psychophysiology, biofeedback, heart rate variability, photobiomodulation, repetitive Transcranial Magnetic Simulation (rTMS) and transcranial Direct Current Stimulation (tDCS); with a focus on treatment of psychiatric, mind-body, and neurological disorders. In addition to research findings and reviews, it is important to stress that publication of case reports is always useful in furthering the advancement of an intervention for both clinical and normative functioning. We strive for high quality and interesting empirical topics presented in a rigorous and scholarly manner. The journal draws from expertise inside and outside of the International Society for Neurofeedback & Research (ISNR) to deliver material which integrates the diverse aspects of the field, to include: *basic science *clinical aspects *treatment evaluation *philosophy *training and certification issues *technology and equipment
