Esophageal Disorders and Their Relationship to Psychiatric Disease
Published in Kevin W. Olden, Handbook of Functional Gastrointestinal Disorders, 2020
Laurence A. Bradley, Joel E. Richter
Two drawbacks are associated with the use of biofeedback interventions for GERD. First, persons with exceptionally low resting LES pressure (<4 mm Hg) might not respond well to treatment given that maximum improvement appears to be limited to twice their baseline pressures. In addition, successful biofeedback training requires special equipment and experience in designing treatment protocols.
Behavior Modification

Biofeedback training is based on monitoring the physiological response one wishes to influence (blood pressure, heart rate, galvanic skin response, muscle tension, etc.) and presenting it in a continuous way to the patient. Concomitantly, the patient is asked to try to change the particular response in a predetermined manner. When the patient succeeds in achieving the desired change, the result is immediately presented as an auditory or a visual signal. The signal serves as a positive reinforcer to help the patient maintain the desired pattern of response.
The role and function of feedback
Published in Andrea Utley, Motor Control, Learning and Development, 2018
Biofeedback is described as a technique that provides information about performance via a signal from an external source which is related to a physiological process (e.g. heart rate, brain activity, muscle activity). This enables performers to alter or improve their performance by using information provided by their own body; however, it must be presented in such a way that people do not become dependent upon it. Although the most common form of biofeedback is that which uses the activity of muscles, electromyography (EMG) can comprise visual, auditory or tactile information (Lauber et al. 2016). EMG feedback is commonly used in a clinical setting and has been shown to be effective in treating patients with a variety of motor difficulties; recent developments have meant that EMG biofeedback training devices can be used at home.
Effects of behavioural swallowing therapy in patients with Parkinson’s disease: A systematic review
Published in International Journal of Speech-Language Pathology, 2023
One study described biofeedback therapy. Athukorala et al. (2014) examined the effects of swallowing skill training with biofeedback in 10 patients with PD-related dysphagia. Skill training exercises consisted of 10 daily sessions that focussed on increased precision in muscle contraction using surface electromyography (sEMG) during swallowing using visual feedback. Each session took one hour, with 100 swallow trials partitioned into five blocks of 20 swallowing trials with dry swallow. The participants completed follow-up after two weeks of treatment, and after two weeks of a non-treatment period to evaluate skill retention. The swallow rate for liquid, sEMG durational parameters of pre-motor time, pre-swallow time, and the Quality of Life in Swallowing Disorders (SWAL-QOL) all improved immediately post-therapy. In addition, a non-treatment period showed short-term retention treatment effects.
Identification of emotions and physiological response in individuals with moderate intellectual disability
Published in International Journal of Developmental Disabilities, 2021

In the study of emotions, new technologies have provided objective instruments for measuring physiological response, particularly the emotional reaction produced in the organism before stressful stimuli based on the activation of the autonomous nervous system (ANS). Biofeedback is a precise way to measure the physiological activity of ANS through brain waves, heart rate, breathing, muscle activity, temperature, and skin conductance (Yucha and Montgomery 2008). Both feedback and neurofeedback have been employed in the evaluation and intervention of neurodevelopmental disorders (Carrick et al.2018, Frederiks et al.2015, Goodman et al.2018). Different studies have found dysfunctions and response heterogeneity in ANS response from individuals with ID, attributed to cognitive rigidity and neurological alterations (Baglio et al.2014, Houwen et al.2016, Murias et al.2017). With respect to interventions, biofeedback has been employed to increase the emotional self-regulation strategies in individuals with ID who showed inadequate behaviors (Gray et al. 2019).
Effectiveness of Low Vision Rehabilitation Using Microperimetric Acoustic Biofeedback Training in Patients with Central Scotoma

The aim of this study was to evaluate the efficacy of low vision rehabilitation through biofeedback training by assessing fixation stability, reading performance and quality of life in patients with central scotoma due to different macular diseases. In the literature, there are several studies evaluating the effect of acoustic biofeedback training, but most of them included a small number of patients with uniform diagnosis and often with AMD. This article attempts to present and interpret both the location of PRL and the response to acoustic biofeedback in different diseases that cause central scotoma including AMD, Stargardt disease, and cone dystrophy. While AMD is the most common cause of central scotoma, Stargardt disease and cone dystrophy are also relatively common hereditary retinal dystrophies. The difference of this study from the previous studies is that the response to biofeedback is also evaluated separately for each diagnostic group. In addition, this study is the first study in which acoustic biofeedback was performed with the MAIA microperimetry device in these disease groups.
