Technological advances and limited mental health care have driven individuals toward self-monitoring devices, with biofeedback emerging as a key method for emotional regulation. Electrodermal biofeedback-though widely used-has shown mixed results in stress and anxiety management. Moreover, measurement sites for self-monitoring devices tend to be non-traditional sites such as the wrist. This study aims to assess the feasibility of a one-time electrodermal biofeedback session on state anxiety and evaluate the wrist as a viable feedback site. A randomized controlled primary study (N = 110) and a follow-up study (N  = 39) to confirm the results of the first study were conducted. Participants were randomized into control, feedback from fingers and feedback from the wrists conditions followed by a 10-min biofeedback session. Our results confirm the efficacy of a 10-min biofeedback session on self-reported state anxiety and skin conductance level, response amplitude and the number of non-specific responses. We found no significant differences between feedback received from the wrists, and feedback from the fingers. Additionally, our findings suggest that skin conductance level, response amplitude and the number of non-specific responses do not show a clear relationship with self-reported anxiety. In conclusion, there is evidence of feasibility of electrodermal biofeedback in managing state anxiety, and the wrist shows promise to be a viable site for biofeedback in anxiety management. Future research should explore the interactions between electrodermal activity and self-reported measures of anxiety to optimize biofeedback interventions.</p>","PeriodicalId":47506,"journal":{"name":"Applied Psychophysiology and Biofeedback","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144276279","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}

The primary objective of the research was to evaluate the impact of a structured biofeedback-based training program designed to enhance music students' capacity for self-regulation and adaptation to performance-related stress. The research employed the Kenny Music Performance Anxiety Inventory (K-MPAI, Chinese version) and the Music Performance Quality Scale (MPQ) to assess changes in anxiety levels and performance outcomes. Participants in the biofeedback training program demonstrated significant reductions in K-MPAI subscale scores: \"Anxiety/Fear\" (- 21.8%), \"Depression/Hopelessness\" (- 36.5%), \"Proximal Somatic Anxiety\" (- 41.6%), \"Memory\" (- 32.1%), and \"Worry\" (- 32.3%). Physiological indicators corroborated these findings, revealing marked improvements in heart rate variability (RMSSD: + 56%, p = 0.0002) and electromyographic relaxation (EMG amplitude: - 36%, p = 0.0013) among participants in the experimental group. Notably, MPQ scores increased by an average of 7.82 points in the experimental group, indicating that the reduction in performance anxiety through biofeedback techniques positively influenced the quality of musical execution.

However, existing VR mindfulness interventions predominantly rely on static natural environments without incorporating interactive elements, limiting their capacity to engage users dynamically. To address this gap, this study introduces an innovative interactive VR mindfulness system, where real-time heart rate variability (HRV) biofeedback dynamically modulates the virtual environment (e.g., fog dissipation, auditory cues, and visual transformations), creating a responsive and immersive experience. We investigated the effects of a single five-minute interactive VR mindfulness session on anxiety, mindfulness states, and HRV, compared to traditional audio-based mindfulness and an non-intervention control. Seventy-five university students with recent anxiety symptoms were randomized into three groups: interactive VR mindfulness (VR-MG), traditional mindfulness (MG), and control (CG). Prior to and following the five-minute intervention, anxiety, mindfulness levels, and physiological data (HRV) were measured for all three groups, with repeated measures analysis of variance performed. The results showed that the five-minute VR mindfulness interactive training significantly improved participants' anxiety levels, enhanced their mindfulness states, and effectively increased HRV, whereas traditional mindfulness and control conditions showed no significant HRV changes. Overall, this study indicates that brief VR mindfulness interactive training has significant effects on improving anxiety and mindfulness states, as well as enhancing HRV, highlighting its potential for psychological health interventions.</p>","PeriodicalId":47506,"journal":{"name":"Applied Psychophysiology and Biofeedback","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144217212","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}

We report here unique treatment responses among participants with high versus low baseline working memory (WM) function. At baseline, among All participants, greater gamma dysregulation (higher resting gcoh) positively correlated with greater WM impairment. Among Active participants, completing gcoh-NFB training lowered the elevated baseline gcoh in participants with lower baseline WM function, and, conversely, increased the relatively lower baseline gcoh in participants with higher baseline WM function. In contrast, completing placebo-NFB produced no gcoh changes, regardless of baseline WM function. Compared to Placebo participants, all Active participants exhibited improved WM with training. The differing gcoh responses to NFB among Active participants suggested multiple neurophysiologic and WM responses during treatment. We selected canonical correlation analysis (CCA) to further evaluate potential latent and divergent responses. CCA identified two statistically significant canonical components; the stronger component representing the expected positive interactions between training-related WM responses, and the weaker component representing diverging interactions between training-related NFB and WM responses.

There is a need to develop novel intervention strategies that can be used as stand-alone techniques or combined with current gold standard post-stroke rehabilitation procedures.

Using machine learning, it examined the relationship between inattention improvement on the Conners' Teacher and Parent Rating Scales (CTPRS) and specific baseline frequency connections within networks relevant to ADHD to find predictors of clinical improvement.

In addition, HRV indicators, particularly RMSSD and RR interval, were markedly elevated after the intervention.
