EEG Theta/Beta Ratio Neurofeedback Training in Healthy Females.

Appl Psychophysiol Biofeedback 2020 May 26. Epub 2020 May 26.

Institute of Psychology, Leiden University, Leiden, The Netherlands.

A growing number of studies suggest that EEG theta/beta ratio (TBR) is inversely related to executive cognitive control. Neurofeedback training aimed at reducing TBR (TBR NFT) might provide a tool to study causality in this relation and might enhance human performance. To investigate whether TBR NFT reduces TBR in healthy participants. Read More

Information Processing in Migraine: A Review of Studies on P300.

Appl Psychophysiol Biofeedback 2020 May 8. Epub 2020 May 8.

Unit of Neurology I.C., Oasi Research Institute - IRCCS, Troina, Italy.

Subjective cognitive dysfunction is common among migraineurs. The aim of this review is to evaluate the usefulness of psychophysiology by means of the P300 component of the event-related potential in the understanding of subtle and sub-clinical changes in cognition that may occur during and between migraine episodes. Some P300 studies suggest a potential impairment of information processing, as reflected by only few findings of interictal decreased amplitude and prolonged latency, ictal augmented amplitude and prolonged latency, changes in cognitive habituation, and limited capacity to relocate attention away from painful stimuli.

State and Trait Mindfulness as Predictors of Skin Conductance Response to Stress.

Appl Psychophysiol Biofeedback 2020 May 4. Epub 2020 May 4.

Department of Psychology, University of Windsor, Ottawa, ON, Canada.

Mindfulness is typically understood as non-judgmental, focused attention on the present moment, although it may be conceptualized as a state, a trait, and an outcome of intervention. There is a limited understanding of the physiological effects of state and trait mindfulness, and it has been a challenge to the research community to measure these effects. This study examined whether state and trait mindfulness are associated with reduced stress response activation in healthy young adults. Read More

Development and Pilot Test of a Virtual Reality Respiratory Biofeedback Approach.

Appl Psychophysiol Biofeedback 2020 May 2. Epub 2020 May 2.

Department of Occupational and Consumer Psychology, Albert-Ludwigs-Universität Freiburg, Engelbergerstr. 41, 79106, Freiburg, Germany.

Breathing exercises with biofeedback have benefits over breathing exercises without biofeedback. However, the traditional measurement of respiratory signals that is required as part of feeding back the breath incurs high cost and effort. We propose a novel virtual reality (VR) based approach to respiratory biofeedback that utilizes the positionally tracked hand controllers integrated into modern VR systems to capture and feedback the respiration-induced abdominal movements.

Appl Psychophysiol Biofeedback 2020 Jun;45(2):99-108

Integrative Oncology, PRISMA Health Upstate Cancer Institute, Greenville, SC, USA.

Chronic cancer-related symptoms (stress, fatigue, pain, depression, insomnia) may be linked with sympathetic nervous system over-activation and autonomic imbalance. Decreased heart rate variability (HRV) is an indicator of autonomic dysregulation that is commonly observed among cancer survivors. HRV biofeedback (HRVB) training induces HRV coherence, which maximizes HRV and facilitates autonomic and cardiorespiratory homeostasis. Read More

Comparison of the Immediate Effects of Audio, Visual, or Audiovisual Gait Biofeedback on Propulsive Force Generation in Able-Bodied and Post-stroke Individuals.

Appl Psychophysiol Biofeedback 2020 Apr 29. Epub 2020 Apr 29.

Division of Physical Therapy, Department of Rehabilitation Medicine, Emory University, 1441 Clifton Rd NE, Atlanta, GA, 30322, USA.

Real-time biofeedback is a promising post-stroke gait rehabilitation strategy that can target specific gait deficits preferentially in the paretic leg. Our previous work demonstrated that the use of an audiovisual biofeedback interface designed to increase paretic leg propulsion, measured via anterior ground reaction force (AGRF) generation during late stance phase of gait, can induce improvements in peak AGRF production of the targeted and paretic limb of able-bodied and post-stroke individuals, respectively. However, whether different modes of biofeedback, such as visual, auditory, or a combination of both, have differential effects on AGRF generation is unknown. Read More

Heart Rate and Breathing Are Not Always in Phase During Resonance Frequency Breathing.

Appl Psychophysiol Biofeedback 2020 Apr 13. Epub 2020 Apr 13.

Rutgers Graduate School of Biomedical Sciences, Newark, USA.

For many years it has been an axiom among practitioners of heart rate variability biofeedback that heart rate and breathing vary in phase with each other when people do resonance frequency breathing. When people breathe at the frequency of the baroreflex system, about 0.1 Hz, heart rate and blood pressure have been found to oscillate 180° out of phase, while heart rate and breathing are in phase (zero-degree phase).

Appl Psychophysiol Biofeedback 2020 Jun;45(2):75-86

Meru Health Inc, Palo Alto, CA, USA.

A rise in the prevalence of depression underscores the need for accessible and effective interventions. The objectives of this study were to determine if the addition of a treatment component showing promise in treating depression, heart rate variability-biofeedback (HRV-B), to our original smartphone-based, 8-week digital intervention was feasible and whether patients in the HRV-B ("enhanced") intervention were more likely to experience clinically significant improvements in depressive symptoms than patients in our original ("standard") intervention. We used a quasi-experimental, non-equivalent (matched) groups design to compare changes in symptoms of depression in the enhanced group (n = 48) to historical outcome data from the standard group (n = 48).

Efficacy of Paced Breathing at the Low-frequency Peak on Heart Rate Variability and Baroreflex Sensitivity.

Appl Psychophysiol Biofeedback 2020 03;45(1):31-37

Department of Rehabilitation Medicine, Asahikawa Medical University Hospital, Asahikawa, Japan.

We developed a simple method for identifying resonance frequency by focusing on the spectral peak of the low-frequency (LF) component of heart rate variability (HRV) and examined the hypothesis that paced breathing at an accurate resonance frequency increases HRV and baroreflex sensitivity (BRS). We assessed a peak frequency of the LF component of the resting HRV by using power spectral analysis under respiratory control at 0.25 Hz, and a resonance frequency, which was evaluated by using the standard breathing maneuver (Lehrer 2007).

Towards a Pragmatic Approach to a Psychophysiological Unit of Analysis for Mental and Brain Disorders: An EEG-Copeia for Neurofeedback.

Appl Psychophysiol Biofeedback 2019 09;44(3):151-172

Laboratoire Plasticité du Cerveau, UMR 8249, ESPCI Paris Tech, UMR 8249, ESPCI Paris Tech, PSL Université Recherche, 10 rue Vauquelin, 75005, Paris, France.

This article proposes what we call an "EEG-Copeia" for neurofeedback, like the "Pharmacopeia" for psychopharmacology. This paper proposes to define an "EEG-Copeia" as an organized list of scientifically validated EEG markers, characterized by a specific association with an identified cognitive process, that define a psychophysiological unit of analysis useful for mental or brain disorder evaluation and treatment. A characteristic of EEG neurofeedback for mental and brain disorders is that it targets a EEG markers related to a supposed cognitive process, whereas conventional treatments target clinical manifestations.

An Anti-hyperventilation Instruction Decreases the Drop in End-tidal CO and Symptoms of Hyperventilation During Breathing at 0.1 Hz.

Appl Psychophysiol Biofeedback 2019 09;44(3):247-256

Faculty of Psychology, University of Warsaw, Stawki 5/7, 00-183, Warsaw, Poland.

Breathing at a frequency of around 0.1 Hz is widely used in basic research and in applied psychophysiology because it strongly increases fluctuations in the cardiovascular system and affects psychological functioning. Volitional control of breathing often leads to hyperventilation among untrained individuals, which may produce aversive symptoms and alter the psychological and physiological effects of the paced breathing.

Biomedical Engineering Department, Institute of Nuclear Medicine and Allied Science (INMAS), Defence Research and Development Organization (DRDO), Delhi, 110054, India.

A complexity (orientation and shape of stimuli) in the mental rotation (MR) task often affects reaction time (RT) and response accuracy, but the nature of such reflections in neuroscientific research is commonly undocumented. A number of studies have explored the effect of complexity and subsequently noted down the differences in performance. However, a few studies explored complexity (in the term of angular disparity) and cognitive strategies with respect to correct responses only. Read More

Examining the Relation Between Physiological and Psychological Components of Stress Reactivity and Recovery in Cigarette Smokers.

Appl Psychophysiol Biofeedback 2019 06;44(2):131-141

Department of Psychology, Rutgers University-New Brunswick, New Brunswick, NJ, USA.

Cigarette smokers exhibit reduced physiological stress reactivity, yet it is unclear whether blunted reactivity predicts differences in subjective recovery and vice versa. The study examined whether basal heart rate and heart rate reactivity were related to recovery in anxiety following stress, and conversely, whether initial self-reported anxiety and anxiety reactivity were related to heart rate recovery. Fifty-six smokers completed a 10-min baseline period, a 4-min stressor, and a 10-min recovery period during which heart rate and anxiety were continuously assessed. Read More

Combining Biofeedback with Stress Management Interventions: A Systematic Review of Physiological and Psychological Effects.

Appl Psychophysiol Biofeedback 2019 06;44(2):71-82

Expertise Unit Psychology, Technology & Society, Thomas More University of Applied Sciences, Molenstraat 8, 2018, Antwerp, Belgium.

Current mental healthcare systems experience difficulties meeting the challenges of a growing population with elevated stress symptoms. Outpatient stress management interventions have already proven to be effective in routine care and recent technological advances now allow to expand such interventions, for example by adding a physiological component like biofeedback. Adding biofeedback to stress management interventions appears promising, but there is a lack of insight into the general conceptualization and evaluation of the resulting interventions, both in relation to psychological and physiological stress indicators.

Acoustic Neurofeedback Increases Beta ERD During Mental Rotation Task.

Appl Psychophysiol Biofeedback 2019 06;44(2):103-115

Department of Neuroinformatics, Institute of Computer Science, Maria Curie-Sklodowska University, Akademicka 9/509, 20-033, Lublin, Poland.

The purpose of the present study was to identify the effect of acoustic neurofeedback on brain activity during consecutive stages of mental rotation of 3D objects. Given the fact that the process of mental rotation of objects is associated with desynchronisation of beta rhythm (beta ERD), it was expected that suppression in this band would be greater in the experimental group than in the controls. Thirty-three participants were randomly allocated to two groups performing the classic Shepard-Metzler mental rotation task (1971). Read More

Heart Rate Variability is Associated with Memory in Females.

Appl Psychophysiol Biofeedback 2019 06;44(2):117-122

Department of Psychiatry, National Cheng Kung University Hospital, College of Medicine, National Cheng Kung University, 138 Sheng Li Road, North Dist., Tainan, 70403, Taiwan.

Research into the association between heart rate variability (HRV) and cognitive function is scarce, particularly with regard to gender differences. HRV in 182 healthy volunteers was assessed by the root mean square of the successive difference (RMSSD) and spectrum analysis, while the Wechsler Memory Scale-Revised (WMS-R) was used to determine memory function. Robust and significant associations were found to exist between HRV (RMSSD and high-frequency HRV) and domains of the WMS-R in females. Read More

Mediators of Change in Capnometry Guided Respiratory Intervention for Panic Disorder.

Appl Psychophysiol Biofeedback 2019 06;44(2):97-102

Institute of Living, 200 Retreat Avenue, Hartford, CT, 06106, USA.

Capnometry guided respiratory interventions have shown promising results in the treatment of panic disorder, but mechanisms of change are not yet well-understood. The current study examined changes in end-tidal carbon dioxide (ETCO), anxiety sensitivity, and perceived control as mediators of panic symptom change. Sixty-nine adults with panic disorder received 4 weeks of respiratory training, and panic symptom severity and potential mediators were assessed at Pre-treatment, Mid-treatment, Post-treatment, 2-month follow-up, and 12-month follow-up.

Respiratory Biofeedback Does Not Facilitate Lowering Arousal in Meditation Through Virtual Reality.

Appl Psychophysiol Biofeedback 2019 03;44(1):51-59

Department of Cognitive Science & Artificial Intelligence, Tilburg University, Dante Building, Room D 330, Warandelaan 2, 5037 AB, Tilburg, The Netherlands.

The current study examined the effectiveness of respiratory biofeedback in lowering subjective and objective arousal after stress. Participants were presented with a meditation session in virtual reality while subjective and objective arousal were measured, the latter measured through ECG and EEG. Three conditions were used: (a) a respiratory biofeedback condition, in which visual feedback was paired to breathing; (b) a control feedback placebo condition, in which visual feedback was not paired to breathing; and (c) a control no-feedback condition, in which no visual feedback was used.
