Review
BACKGROUND
Ambulant biofeedback devices can be used to provide real-time feedback for trauma patients on weight-bearing regimes. The devices also enable prescribing clinicians to monitor and train patients' level of weight-bearing. However, there is limited evidence regarding the feasibility of use of such devices in controlling weight-bearing, and their full potential remains to be elucidated.
OBJECTIVE
To investigate the feasibility of using ambulant biofeedback training devices to improve compliance with weight-bearing regimes in trauma patients with lower extremity fractures.
METHODS
A literature review of the feasibility and clinical validity of ambulant biofeedback devices.
RESULTS
Three clinically validated biofeedback devices were found feasible for use in monitoring the compliance of patients who have lower extremity fractures with different weight-bearing regimes.
CONCLUSION
Further information about the feasibility and clinical validity of biofeedback training devices is nee-ded in order to optimize weight-bearing instructions for patients.

Review
Brain-computer interfaces (BCIs) have attracted much attention recently, triggered by new scientific progress in understanding brain function and by impressive applications. The aim of this review is to give an overview of the various steps in the BCI cycle, i.e., the loop from the measurement of brain activity, classification of data, feedback to the subject and the effect of feedback on brain activity. In this article we will review the critical steps of the BCI cycle, the present issues and state-of-the-art results. Moreover, we will develop a vision on how recently obtained results may contribute to new insights in neurocognition and, in particular, in the neural representation of perceived stimuli, intended actions and emotions. Now is the right time to explore what can be gained by embracing real-time, online BCI and by adding it to the set of experimental tools already available to the cognitive neuroscientist. We close by pointing out some unresolved issues and present our view on how BCI could become an important new tool for probing human cognition.

Review
Systems theory has long been used in psychology, biology, and sociology. This paper applies newer methods of control systems modeling for assessing system stability in health and disease. Control systems can be characterized as open or closed systems with feedback loops. Feedback produces oscillatory activity, and the complexity of naturally occurring oscillatory patterns reflects the multiplicity of feedback mechanisms, such that many mechanisms operate simultaneously to control the system. Unstable systems, often associated with poor health, are characterized by absence of oscillation, random noise, or a very simple pattern of oscillation. This modeling approach can be applied to a diverse range of phenomena, including cardiovascular and brain activity, mood and thermal regulation, and social system stability. External system stressors such as disease, psychological stress, injury, or interpersonal conflict may perturb a system, yet simultaneously stimulate oscillatory processes and exercise control mechanisms. Resonance can occur in systems with negative feedback loops, causing high-amplitude oscillations at a single frequency. Resonance effects can be used to strengthen modulatory oscillations, but may obscure other information and control mechanisms, and weaken system stability. Positive as well as negative feedback loops are important for system function and stability. Examples are presented of oscillatory processes in heart rate variability, and regulation of autonomic, thermal, pancreatic and central nervous system processes, as well as in social/organizational systems such as marriages and business organizations. Resonance in negative feedback loops can help stimulate oscillations and exercise control reflexes, but also can deprive the system of important information. Empirical hypotheses derived from this approach are presented, including that moderate stress may enhance health and functioning.

Review
BACKGROUND
The aim of this article is to present a short review of noninvasive, nonpharmacological treatment methods used in somatic illnesses that fall under the umbrella of approach called behavioral medicine.
METHODS
The narrative review method was applied in the study. Science paper databases, including PubMed, had been used to retrieve papers on therapeutic methods used in clinical setting that meet the broad criteria of behavioral medicine definition as stated in the Charter of International Behavioral Medicine Society.
RESULTS
Main groups of methods, disorders in which they are being employed and their effectiveness, have been identified.
CONCLUSIONS
Behavioral medicine is grouping treatment methods and interventions that hold large potential for clinical setting. Two groups of methods can be distinguished by the scrutiny and level of evidence gathered in their effectiveness assessment; for biofeedback, guided imagery, and hypnosis techniques, comprehensive evidence reports in the framework of U.S. Evidence Synthesis Program exist. Meditation techniques, disclosure therapies, and relaxation methods are less well assessed. Broader employment of behavioral medicine therapies in clinical setting is possible after addressing two major problems in the field, which are deficiencies in quality evidence of effectiveness for many of the methods and their insufficiencies in underlying therapeutic mechanism knowledge.

BACKGROUND
It is now known that with appropriate exercises, the functions of the muscles in the body ameliorate and increase in strength. We applied pelvic floor muscle relaxation training and exercises that strengthen the abdominal and pelvic muscles in combination with biofeedback therapy (BFT) to patients with dyssynergic defecation (DD).
METHODS
Patients who met the criteria for DD and had no underlying organic cause were included in this study. The electromyography (EMG) technique was used for BFT therapy. Patients had received at least six sessions of BFT. BFT was considered successful in patients when the DD pattern in anorectal manometry (ARM) disappeared and/or adequate anal relaxation was obtained following BFT and in patients who had full clinical recovery.
RESULTS
Data of 104 patients (58 females [55.8%] and 46 males [44.2%]) was evaluated. Abdominal and rectal symptoms disappeared in 71 (68.26%) patients. Of the patients who achieved symptomatic improvement, 58 (55.76%) saw a disappearance of the dyssynergic defecation pattern. When the differences between anal sphincter pressures before and after treatment were compared in patients who responded to BFT and those who did not, no significant differences were observed, but significant changes were found in anal squeezing pressures. It was found that those who had high squeezing pressures before BFT, those who increased their squeezing pressures after BFT, and those who decreased their resting pressure responded better to BFT.
CONCLUSIONS
In this study, BFT was found to be more effective in those with a high squeezing pressure and those that increased squeezing pressure after BFT. These findings will influence the treatment of patients with dyssynergic defecation who do not respond to treatment. A combination of abdominal and pelvic floor muscle exercises and BFT increases patient response.

Modified Biofeedback (Conditioned Biofeedback) Promotes Antinociception by Increasing the Nociceptive Flexion Reflex Threshold and Reducing Temporal Summation of Pain: A Controlled Trial.
This study examined whether a modified version of biofeedback (ie, Conditioned Biofeedback) that incorporated placebo analgesia-like manipulations could promote antinociception in healthy, pain-free participants. During Conditioned Biofeedback (n = 28), sympathetic arousal level was displayed visually and participants were asked to reduce it while they received painful electric stimulations that were surreptitiously controlled by their arousal level. Thus, electric pain decreased as arousal decreased to associate successful arousal-reduction/relaxation with pain relief, and to promote expectations for future pain relief. A Biofeedback Only group (n = 24) controlled for the general effects of biofeedback/relaxation. A Biofeedback+Shock group (n = 21) controlled for the effects of practicing biofeedback during painful shocks. Nociceptive flexion reflex (NFR) threshold and temporal summation of pain (TS-pain) were used to assess changes in spinal nociception and pain facilitation, respectively. Results indicated all groups showed pre- to postbiofeedback increases in NFR threshold, but only the Conditioned Biofeedback group showed pre- to postbiofeedback reductions in TS-pain. Moreover, Conditioned Biofeedback resulted in a persistent (prebiofeedback) increase in NFR threshold across sessions, whereas Biofeedback Only resulted in a persistent (prebiofeedback) decrease in TS-pain. In sum, Conditioned Biofeedback may promote antinociception in healthy participants thus reducing risk for chronic pain. The study was registered prospectively on ClinicalTrials.gov (TU1560). PERSPECTIVE: A modified version of biofeedback that employs placebo analgesia manipulations was successful in increasing descending inhibition and reducing pain facilitation in healthy volunteers. As a result, it may be an effective means of reducing risk of future chronic pain onset by promoting an antinociceptive pain profile.

Review
BACKGROUND
Heartrate variability biofeedback (HRVB) is a non-invasive treatment in which patients are assumed to self-regulate a physiological dysregulated vagal nerve. Although the therapeutic approach of HRVB is promising in various stress-related disorders, it has only been offered on a regular basis in a few mental health treatment settings.
AIM
To analyse the efficacy of HRV biofeedback as an additional psychophysiological treatment for depression and PTSD.
METHOD
Systematic review with search terms HRV, biofeedback, PTSD, depression, panic disorder and anxiety disorder.
RESULTS
Our search of the literature yielded 789 studies. After critical appraisal using the GRADE method, we selected 6 randomised controlled trials (RCTs) and 4 relevant studies. The RCTs with control groups 'treatment as usual' and muscle relaxation training revealed significant clinical efficacy and better results than control conditions after 4 to 8 weeks training.
CONCLUSION
Although this systematic review shows the popularity of HRV in literature, it does not indicate that HRVB really has been reviewed systematically. Significant outcomes of this limited number of randomised studies indicate there may be a clinical improvement when HRVB training is integrated into treatment of PTSD and depression, particularly when this integration procedure is combined with psychotherapy. More research needs to be done with larger groups and further efforts are needed to integrate HRVB into treatment of stress-related disorders in psychiatry. Future research also needs to focus on the psychophysiological mechanisms involved.

Randomized Controlled Trial
BACKGROUND
Cognitive-behavioral therapy (CBT) and biofeedback therapy are commonly regarded as effective treatment modalities for panic disorder. The aim of this study was to establish a Taiwanese version of an integrated cognitive-behavioral and biofeedback therapy (ICB) and examine its effects on panic disorder using psychological and physiological indicators.
METHODS
Thirty patients with panic disorder were enrolled in this study. They were randomly assigned to either the ICB group (n = 15) or the treatment as usual (TAU) group (n = 15). The intervention consisted of six sessions, conducted once a week. Psychological indicators were measured at baseline (prior to intervention), week 3, and week 6, while physiological indicators were measured at baseline and week 6. The psychological indicators included five scales, with the Panic Disorder Severity Scale (PDSS) being the primary measure. The physiological indicators included respiratory sinus arrhythmia (RSA) and skin conductance, which respectively represent parasympathetic and sympathetic activity.
RESULTS
Considering all participants, PDSS scores significantly decreased over time, but the difference between the ICB and TAU groups did not reach statistical significance. Among the physiological indicators, resting-state RSA and RSA under relaxation showed significant between-group differences over time, with the ICB group demonstrating a more pronounced improvement in RSA.
CONCLUSION
In the context of existing pharmacological treatments, the benefits of ICB for panic disorder may not be observable through psychological indicators. However, it can lead to enhancement of parasympathetic activity as evidenced by the physiological indicators.
