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.
