One hundred and fifty-six (n = 156) undergraduate student participants were fitted with a chest band to monitor cardiovascular activity and completed online demographic and psychosocial surveys. Participants were grouped as healthy or displaying probable mental health symptoms (pMH; n = 94, 60.25% of sample) based on scoring above associated inventory thresholds for depression, anxiety, and posttraumatic stress disorder. Subsequently, cardiovascular activity was measured to capture HRF under the established “RRR” experimental stress paradigm: a <i>resting</i> baseline, <i>reactivity</i> to an acute stressor task, and a paced breathing <i>recovery</i>. Results support the global study aim in which HRF significantly differentiated between each RRR condition (p &lt; 0.001). While healthy and pMH individuals did not significantly differ within individual conditions, exploratory analyses revealed that healthy individuals displayed significantly greater HRF reactivity between conditions (p’s &lt; 0.001) in comparison to the pMH sample, which displayed a more blunted pattern. Overall, this study establishes associations between HRF and mental health, serving as a promising biomarker that contributes towards the AL and NVI models of stress regulation and adaptation. HRF may also identify early signs of adverse dysregulation in samples otherwise considered “healthy”, while addressing the limitations of frequently used HRV biomarkers in non-clinical studies.</p></div>","PeriodicalId":47506,"journal":{"name":"Applied Psychophysiology and Biofeedback","volume":"51 1","pages":"29 - 47"},"PeriodicalIF":2.4,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144974051","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}

Fifty-eight participants with TBI enrolled; 49 completed the study (HRV-B: 25, mean age 27.1; sham: 24, mean age 26.6). Participants attended five weekly sessions.

The influence of Brief Mindfulness Meditation (BMM) on HRV contains gaps in the literature. This study aims to investigate the influence of BMM on HRV. A systematic search was conducted in four databases (i.e., PubMed NCBI, Cochrane Library, Scopus, and Web of Science). To be included, these studies were required to evaluate HRV before and during or after a BMM intervention. The methodological quality of the included studies was evaluated with the revised Cochrane Risk-of-Bias and the quality of the evidence was assessed with the Grading of Recommendations Assessment, Development and Evaluation. Seven studies met the inclusion criteria. Three studies had within subject design, two studies compared BMM with other relaxation techniques, one study was a controlled trial, and one study was an uncontrolled trial. Three studies, including 120 participants, found that BMM is associated with an increase of Root Mean Square of Successive Differences (RMSSD). Two studies reported an increase of the LF/HF ratio; however, the quality of the evidence was low. Although the large amount of heterogeneity can be seen as the main limitation, the results suggest that RMSSD may increase in the short-term during or after BMM, suggesting that BMM might be a promising psychological intervention to temporally reduce the physiological stress of the population.

These limitations can induce a decline in system dynamism and user motivation. However, barriers can be overcome by integrating immersive virtual reality into a neurofeedback system to increase motivation, interest, and adherence through immersion and a sense of presence.

In this single-blinded, randomized controlled trial, 40 children aged 5–10 years with DCD were assigned to an intervention group (PB + OT) or a control group (OT alone). The Developmental Coordination Disorder Questionnaire (DCD-Q) provided a subjective evaluation of motor coordination, including FMS and proprioception.

Pressure biofeedback (PB) pattern tracking quantified fine motor precision and proprioceptive regulation using Root Mean Square Error (RMSE) and visual-motor integration using the Correlation Coefficient (CC). Post-intervention, the intervention group showed significantly more improvements than controls in DCD-Q, BOT-2, RMSE, and CC scores. DCD-Q and BOT-2 scores increased (<i>p</i> &lt; 0.05), indicating enhanced manual dexterity, including proprioception and fine motor skills.
