Role Of Heart Rate Variability Biofeedback In Cognitive Performance, Chronic Pain, And Related Symptoms, James P. Winstead

Theses and Dissertations

Over-modulation of the sympathetic nervous system and reduced heart rate variability (HRV) are commonly overlooked components of pain, poor cognition (decreased attention, recall, and cognitive processing), depression, stress, and fatigue. HRV Biofeedback (HRVB) training induces HRV coherence to balance the autonomic system. Paced breathing (~6 breaths/minute) increases HRV coherence. This randomized, controlled intervention trial tested the hypothesis that HRVB would improve HRV coherence, pain (severity, interference, and catastrophizing), cognitive performance, and reduce depressive, stress, and fatigue symptoms and pain medication use in veterans. Participants were randomized to previously established HRVB or control protocols. Each participant completed a Baseline Assessment, 6 …

Effect Of Heart Rate Variability Biofeedback On Sleep, Joshua Mercadel

Theses and Dissertations

Healthy amounts of sleep is vital for normal human functions such as daily learning, memory, emotional state and cardiovascular function. Studies conducted previously have shown sleep deprivation to be associated with increases in sympathetic activity contributing to autonomic nervous system (ANS) dysregulation. HRV biofeedback (HRVB) training induces HRV coherence, a condition that maximizes HRV and facilitates autonomic and cardiorespiratory homeostasis. This randomized, controlled, intervention trial will test the hypothesis that HRVB can improve HRV coherence and increase overall sleep quality. Patients are randomized to previously established HRVB or sham protocols (n=40 each, total planned enrollment N=80). Each participant completes a …

Participant Accuracy And Impact Of Biofeedback On A Skilled Swallowing Task, Caris Giessler

Senior Honors Projects, 2010-2019

Biofeedback is as a visual way to self-assess muscle contraction, particularly during rehabilitative exercises. Speech language pathologists and otolaryngologists have investigated the use of visual biofeedback in swallowing therapy, especially for volitional swallowing rehabilitative exercises such as the effortful swallow, which requires the patient to maximally swallow with all their strength. In contrast to the effortful swallow, “effortful skilled swallowing” is the ability to swallow with a specific and precise amount of effort, which is an emerging topic in dysphagia research. Dysphagia, also known as disordered swallowing, can be an organic congenital disorder treated via feeding tubes, or an acquired …

Parent Perceptions Of Biofeedback Treatment Effectiveness For Pediatric Migraine, Andrea Grando Weber

Walden Dissertations and Doctoral Studies

Gate control theory posits the idea that the brain and spinal cord have the ability to control the perception of pain sensation throughout the body. Biofeedback provides a proven way to teach a person how they may control their heart rate, breathing, and skin temperature. Through this process, individuals learn to lessen their migraine frequency and intensity. There are no studies to date that have measured the effectiveness of biofeedback in conjunction with medication for migraines in children despite established evidence of success in adults. In this study, an online format via SurveyMonkey was used to document the perceptions of …

The purpose of this case report is to demonstrate the effectiveness of adjusting this patient’s static alignment (ie. position while seated on bicycle, but not actively pedaling) on the bike and modifying her habitual pedaling pattern. Methods …

The Effectiveness Of Neurofeedback And Heart Rate Variability Biofeedback For Individuals With Long-Term Post-Concussive Symptoms, Marquise Bonn

Electronic Thesis and Dissertation Repository

Case studies have shown that low resolution electromagnetic tomography (LoRETA) neurofeedback is effective for many psychological disorders, but it’s effectiveness for individuals experiencing persistent post-concussive symptoms (PPCS) is uncertain. Individuals with PPCS (n = 7) received an eight-week LoRETA neurofeedback and heart rate variability biofeedback intervention. Change in symptoms, driving simulation performance, electroencephalographic z-score deviations, and heart rate variability were compared to PPCS (n = 9) and healthy (n = 8) control groups. Statistical analyses revealed that the intervention significantly reduced electroencephalographic z-score deviations (p < 0.005) compared to PPCS controls. Additionally, headache, nausea, and dizziness symptoms were reduced in the intervention group (p = 0.003) and the PPCS controls (p = 0.001) compared to healthy …

Ultrasound Visual Biofeedback And Accent Modification: Effects On Consonant And Vowel Accuracy For Mandarin English Language Learners, Courtney Armstrong

Electronic Theses and Dissertations

The number of individuals in the United States who speak languages other than English continues to increase. With the increase of language diversity comes a potential rise in communication challenges for those who speak with non-mainstream American English accents as English language learners. A portion of these individuals may elect to seek accent modification services, perhaps due to decreased intelligibility or communication breakdowns. Thus, speech-language pathologists must research and provide effective techniques to enhance intelligibility of all American English speakers for optimal communication. Few approaches employ a variety of treatment methods to improve speech sound accuracy, naturalness and intelligibility to …

Effect Of Biofeedback And Exercise Type On Neural Swallowing Control, Rachel J. Rinehart

Senior Honors Projects, 2010-2019

The clinical efficacy of swallowing exercises is well established in swallowing literature, and biofeedback has been shown to augment cortical hemodynamic response (HDR) during normal swallowing. This study compared HDR during swallowing exercises with and without biofeedback to HDR during normal swallows with and without biofeedback. Healthy adult participants (n=6, mean age=50.83 male=2) were recruited and trained on the following conditions: normal swallowing, swallowing exercise in which a specific physiological target was given (skilled), and swallowing exercises in which no specific physiological target had to be achieved (non-skilled). Biofeedback consisted of submental surface electromyography (sEMG) signals displayed visually. HDR were …

Tuning Up The Old Brain With New Tricks: Attention Training Via Neurofeedback, Yang Jiang, Reza Abiri, Xiaopeng Zhao

Sanders-Brown Center on Aging Faculty Publications

Neurofeedback (NF) is a form of biofeedback that uses real-time (RT) modulation of brain activity to enhance brain function and behavioral performance. Recent advances in Brain-Computer Interfaces (BCI) and cognitive training (CT) have provided new tools and evidence that NF improves cognitive functions, such as attention and working memory (WM), beyond what is provided by traditional CT. More published studies have demonstrated the efficacy of NF, particularly for treating attention deficit hyperactivity disorder (ADHD) in children. In contrast, there have been fewer studies done in older adults with or without cognitive impairment, with some notable exceptions. The focus of this …

The Efficacy Of Biofeedback And Its Use Towards Adhd, Darius Witold Bieganski

CMC Senior Theses

Attention deficit hyperactivity disorder (ADHD) is a psychopathology commonly characterized by general inattentiveness and/or a lack of impulse control resulting in hyperactive tendencies. ADHD is estimated to cost the United States roughly $266 billion every year. ADHD is currently treated via medications, cognitive behavioral therapy, or more recently, neurofeedback. Neurofeedback – and biofeedback in general – is the process of providing a patient with information about autonomic bodily functions so that they may control said autonomic function. In the case of ADHD, neurofeedback focuses on reinforcing the behaviors and sensations associated with attentiveness. Currently however, neurofeedback systems are large and …
