A Meta-analysis Study","authors":"Kana Matsuyanagi","doi":"10.1007/s10484-025-09701-5","DOIUrl":"10.1007/s10484-025-09701-5","url":null,"abstract":"<div><p>Post-traumatic stress disorder (PTSD) remains a significant clinical challenge with limited treatment options. Although electroencephalogram (EEG) neurofeedback has garnered attention as a prospective treatment modality for PTSD, no comprehensive meta-analysis has been conducted to assess its efficacy and compare different treatment protocols. This study aims to provide a multi-variable meta-regression analysis of EEG neurofeedback’s impact on PTSD symptoms, while also assessing variables that may influence treatment outcomes. A systematic review was performed to identify controlled studies exploring for the efficacy of EEG neurofeedback on PTSD. The overall effectiveness was evaluated through meta-analysis, and a multi-variable meta-regression was employed to discern factors affecting the EEG neurofeedback efficacy. EEG neurofeedback demonstrated a statistically significant reduction in PTSD symptoms immediately post-intervention, with sustained effects observed at one-month and three-month follow-ups. A sub-analysis of sham-controlled studies confirmed that outcomes were not attributable to placebo effects. Sensitivity analysis revealed that excluding two outlying studies resolved heterogeneity entirely, and all subsequent analyses were conducted on the refined dataset. While initial analyses identified target frequency, target region, and feedback modality as significant moderators, meta-regressions controlling for publication year revealed that these effects were confounded by temporal trends in study design and methodological rigor. In contrast, variables related to treatment duration, such as session number, session length, or weeks of intervention, were not significant moderators. These findings suggest that EEG neurofeedback is robust across protocol variations and highlight the importance of methodological advancements in interpreting treatment efficacy. EEG neurofeedback emerges as a promising and robust treatment modality for PTSD, demonstrating sustained therapeutic effects across follow-up periods. Our findings confirm its efficacy beyond placebo effects and highlight the stability of outcomes across diverse neurofeedback protocols. This study underscores the importance of methodological rigor and standardization in EEG neurofeedback research and advocates for larger, well-controlled trials to refine and optimize treatment protocols. These findings reaffirm EEG neurofeedback’s potential as a cost-effective and scalable intervention, while encouraging future research into alternative methodologies to enhance efficacy and expand accessibility.</p></div>","PeriodicalId":47506,"journal":{"name":"Applied Psychophysiology and Biofeedback","volume":"50 3","pages":"329 - 348"},"PeriodicalIF":2.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143617587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A randomised controlled trial was conducted with 150 patients with rectal cancer who were randomly assigned to either the intervention group (<i>n</i> = 75) or the control group (<i>n</i> = 75). The intervention group received 16 sessions of EEG biofeedback therapy over 8 weeks, whereas the control group received standard care. Anxiety levels were assessed using the State-Trait Anxiety Inventory at baseline, post-intervention, 3-month follow-up, 6-month follow-up and 12-month follow-up. Secondary outcomes, including quality of life, sleep quality, treatment adherence, cortisol levels and heart rate variability (HRV), were also evaluated. The intervention group showed significant reductions in state anxiety (<i>p</i> &lt; 0.001) and trait anxiety (<i>p</i> &lt; 0.001) compared with the control group at all post-intervention time points. Significant improvements were also observed in the intervention group for quality of life (<i>p</i> &lt; 0.001), sleep quality (<i>p</i> &lt; 0.001), treatment adherence (<i>p</i> &lt; 0.001), cortisol levels (<i>p</i> &lt; 0.01) and HRV (<i>p</i> &lt; 0.01). The effects were maintained at the 12-month follow-up. Electroencephalographic biofeedback therapy is an effective non-pharmacological intervention for reducing anxiety levels and improving overall well-being in patients with rectal cancer. The findings suggest that incorporating EEG biofeedback therapy into the standard care of patients with rectal cancer may enhance their psychological well-being, quality of life, sleep quality, treatment adherence, physiological stress responses and autonomic function. Long-term benefits were observed, indicating the sustainability of the intervention’s effects.

The purpose of the present study was to examine whether a moderate, balanced approach to measurement, or individualized allostasis, might better capture healthy functioning. To assess balanced functioning, the Assessment of Schema Adaptability Profile - Revised (ASAP-R) was used, and wellbeing was assessed using the Depression, Anxiety, and Stress scale (DASS) and heart rate variability (HF HRV and RMSSD). The IPIP NEO 120 was used to assess the Big 5 model of personality.

Current neuroscience research indicates, however, that our initial awareness of whether something is good, bad, or neutral, is a predominantly affective process, with our core affect being a representation of how the body evaluates life situations over time. We concur with what is now the prevailing view that dualistic theories of mind and body as essentially separate entities are mistaken and have contributed to problematic conceptions of cognition and affect as radically independent operations, one being performed by the mind, the other by the body. In reality, affect and cognition are both bodily processes, and as such are inseparable and interdependent. Affect provides the primary appraisal of the body’s current situation, while cognition builds off the affective response, providing a secondary and often more thorough appraisal. We therefore propose a revised, non-dualistic Transactional Model emphasizing the embodied mind in which our core affect provides the foundation for our primary appraisals and a stronger foundation for conducting psychotherapy.</p></div>","PeriodicalId":47506,"journal":{"name":"Applied Psychophysiology and Biofeedback","volume":"50 2","pages":"197 - 211"},"PeriodicalIF":2.2,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143582382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Strengthening PFMs through exercise is effective, yet invasive treatment protocols deter adherence. Non-invasive surface electromyography (sEMG) provides a promising alternative for assessing PFM strength. This study evaluates a reinforcement-based strategy (R-MVIC) against standard verbal encouragement (SVE) for estimating the maximal voluntary isometric contraction strength (MVIC) of PFMs. Using a single-case reversal design (ABAB), we compared peak amplitudes across experimental and control conditions. All experimental sessions occurred in a small examination room at a major University. Using an (AB)^k single-case research design power analysis to determine our N, we recruited ten participants who performed isolated PFM contractions. The R-MVIC condition involved pre-training, task-specific instructions, criterion-based feedback, and an extinction burst manipulation. To determine the strength of muscle contraction, we used sEMG, placed over the transverse abdominis/internal oblique (TrA/IO) site, to measure muscle activity in microvolts (mV). Results indicated R-MVIC produced significantly higher peak amplitudes compared to SVE, with a mean difference of 746 mV, representing a 52% increase. The R-MVIC condition consistently evoked stronger contractions, demonstrating the efficacy of feedback and extinction bursts in enhancing MVIC estimates. These findings suggest that R-MVIC is a valuable strategy for improving estimates of PFM strength. Overall, the results suggest that sEMG-based biofeedback provides a non-invasive technology for improving treatment protocols.</p></div>","PeriodicalId":47506,"journal":{"name":"Applied Psychophysiology and Biofeedback","volume":"50 3","pages":"481 - 490"},"PeriodicalIF":2.4,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143484405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To characterize several aspects of autonomic functioning, we recorded simultaneously pupil diameter, heart rate and electrodermal activity during 5 min of rest in 44 children (6–12 years old, 22 autistic) and 42 adults (19–52 years old, 21 autistic). Several parameters allowed to characterize tonic and phasic indices of sympathetic and parasympathetic systems at rest. Autistic children exhibited the expected pattern of parasympathetic under-activation at rest compared to their typically developing (TD) peers, and with a tendency for a higher phasic sympathetic activity. Adults exhibited a reverse autonomic pattern, with autistic individuals showing higher sympathetic tonus and lower sympathetic phasic activity than their TD peers. In conclusion, we observed an autonomic disequilibrium at rest both in autistic children and adults, but with opposite patterns that could reflect adaptive compensation mechanisms during maturation. This disequilibrium in autistic children would switch from excessive phasic components to excessive tonic components in adults, possibly subtended by an atypical locus coeruleus functioning.</p></div>","PeriodicalId":47506,"journal":{"name":"Applied Psychophysiology and Biofeedback","volume":"50 3","pages":"465 - 480"},"PeriodicalIF":2.4,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12331820/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143469636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
