Abstract

Posttraumatic stress disorder (PTSD) encompasses various psychological symptoms and a high early dropout rate due to treatment unresponsiveness. In recent years, neurofeedback has been implemented to control PTSD’s psychological symptoms through physiological brain regulation. However, a comprehensive analysis concerning its efficacy is lacking. Therefore, we conducted a systematic review and meta-analysis to determine neurofeedback’s effect on reducing PTSD symptoms. We analyzed randomized and non-randomized controlled trials (RCTs) from 1990 to July 2020, evaluating neurofeedback treatments for those diagnosed with PTSD and their symptoms. In addition, we calculated the standardized mean difference (SMD)using random-effects models to estimate effect sizes. We assessed ten articles comprising 276 participants, with a − 0.74 SMD (95% confidence interval = − 0.9230, − 0.5567), 42% I², moderate effect size, and − 1.40 to -0.08 prediction intervals (PI). Neurofeedback was more effective for complex trauma PTSD patients than single trauma. Increasing and lengthening sessions are more effective than fewer, condensed ones. Neurofeedback positively affected arousal, anxiety, depression, and intrusive, numbing, and suicidal thoughts. Therefore, neurofeedback is a promising and effective treatment for complex PTSD.

神经反馈对创伤后应激障碍症状的影响:系统回顾和荟萃分析

创伤后应激障碍（PTSD）包括各种心理症状和由于治疗无反应而导致的高早期辍学率。近年来，神经反馈已被用于通过大脑生理调节来控制创伤后应激障碍的心理症状。然而，缺乏对其疗效的全面分析。因此，我们进行了一项系统综述和荟萃分析，以确定神经反馈对减少创伤后应激障碍症状的影响。我们分析了1990年至2020年7月的随机和非随机对照试验（RCT），评估了被诊断为创伤后应激障碍患者及其症状的神经反馈治疗。此外，我们使用随机效应模型计算了标准化平均差（SMD），以估计效应大小。我们评估了包括276名参与者的10篇文章 0.74 SMD（95%置信区间 = − 0.9230，− 0.5567），42%I2，中等效应大小，以及− 1.40至-0.08的预测区间（PI）。神经反馈对复杂创伤创伤后应激障碍患者比单一创伤更有效。增加和延长疗程比减少和缩短疗程更有效。神经反馈积极影响唤醒、焦虑、抑郁以及侵入性、麻木和自杀念头。因此，神经反馈是治疗复杂创伤后应激障碍的一种有前景且有效的方法。

期刊介绍： Applied Psychophysiology and Biofeedback is an international, interdisciplinary journal devoted to study of the interrelationship of physiological systems, cognition, social and environmental parameters, and health. Priority is given to original research, basic and applied, which contributes to the theory, practice, and evaluation of applied psychophysiology and biofeedback. Submissions are also welcomed for consideration in several additional sections that appear in the journal. They consist of conceptual and theoretical articles; evaluative reviews; the Clinical Forum, which includes separate categories for innovative case studies, clinical replication series, extended treatment protocols, and clinical notes and observations; the Discussion Forum, which includes a series of papers centered around a topic of importance to the field; Innovations in Instrumentation; Letters to the Editor, commenting on issues raised in articles previously published in the journal; and select book reviews. Applied Psychophysiology and Biofeedback is the official publication of the Association for Applied Psychophysiology and Biofeedback.
