“…The Association for Applied Psychophysiology and Biofeedback (AAPB) defines BFT as a process that provides real-time information from psychophysiological recordings about the levels at which physiological system are functioning ( 17 ). BFT is an assistive tool that makes patients aware of a physiological function of their bodies and enables them to self-regulate the incorrect pattern ( 17 ). BFT, as a conditioning treatment, is suitable when the concerned pathophysiological mechanisms are known and the voluntary control of the responses can be learned at a conscious level ( 6 ).…”

Background: Dyssynergic defecation is a major cause of chronic functional constipation as a common digestive complaint. We clinically evaluated the effects of biofeedback therapy on the pelvic floor motion indices through magnetic resonance (MR) defecography, quality of life and depression in patients with dyssynergic defecation. Methods: In this clinical trial study, among patients referring to the Colorectal Clinic of Hazrat Rasoul Hospital, 22 subjects were randomly assigned into two equal groups (n= 11) to receive either standard only or biofeedback and standard therapy. Dynamic changes of the pelvic floor were measured by MR defecography. During the simulated defecation, two MR defecography dynamic indices including abnormal anorectal angle change and perineal descent were measured before and after treatment. The effects of biofeedback therapy on patients’ symptoms, quality of life and severity of depression were assessed and compared with the standard therapy. Statistical analysis was carried out using independent _t-test and Mann-Whitney test. Results: Paradox index (p< 0.001), perineal descent index (p< 0.001), depression (p< 0.1), physical function (p< 0.001), vitality (p< 0.001) and role emotion (p< 0.001) significantly improved in the biofeedback therapy group in contrast to the standard therapy SDT group. Conclusion: Biofeedback therapy appears to be effective in improving symptoms of functional constipation and dysfunction of pelvic floor motion as well as patient’s quality of life and depression state. MR defecography is able to show the changes in dynamic indices of the pelvic floor through biofeedback therapy.

“…In the first, the motion of parts of the body results in the activation of the limb, whereas, in the latter, biosignals, generated from the electrical activity of muscles, are detected and interpreted in order to generate commands for controlling the prosthesis. Nevertheless, there is ongoing research seeking other forms of control based on more natural strategies, such as those that employ brain or neuronal activity together with sensory feedback [5][6][7][12][13][14].…”

“…Second, we further envision that our results will serve as the grounds for interesting applications that combine the fields of virtual reality (VR) and applied physiology, such as Biofeedback systems. Biofeedback systems are loop systems in which real time information from psychophysiological recordings is provided to the user, who uses it as a means for improving performance [18]. Most of the existing VR systems coupled with Biofeedback are not yet fully integrated.…”

Physiological Arousal Quantifying Perception of Safe and Unsafe Virtual Environments by Older and Younger Adults

Physiological arousal has been increasingly applied to monitor exploration (or navigation) of a virtual environment (VE), especially when the VE is designed to evoke an anxiety-related response. The present work aims to evaluate human physiological reactions to safe and unsafe VEs. We compared the effect of the presence of handrails in the VE in two different samples, young and older adults, through self-reports and physiological data: Electrodermal activation (EDA) and electrocardiogram (ECG) sensors. After navigation, self-report questionnaires were administered. We found that the VEs evoked a clearly differentiated perception of safety and unsafety demonstrated through self-reports, with older adults being more discriminative in their responses and reporting a higher sense of presence. In terms of physiological data, the effect of handrails did not provoke significant differences in arousal. Safety was better operationalized by discriminating neutral/non-neutral spaces, where the reaction of older adults was more pronounced than young adults. Results serve as a basis for orienting future experiments in the line of VE and applied physiology usage in the architectural spaces design process. This specific work also provided a basis for the development of applications that integrate virtual reality and applied biofeedback, tapping into mobility and ageing.
