    Clinical biofeedback procedures are highly effective ameliorating a variety of symptoms that range from urinary incontinence to hypertension as well as assess a person's somatic awareness by making the invisible visible. The paper reviews the biofeedback process and some psychosomatic applications. Psychosomatic patients often demand more skills than just attaching them to the equipment. Successful treatment includes a) assessing physiology as a diagnostic strategy, b) explaining the illness processes and healing strategies that are congruent with patients' perspective, c) reframing the patients' illness beliefs, and d) psychophysiological training with homework practices to generalize the skills. This process is illustrated through the description of a single session with a patient who experienced severe gastrointestinal distress and insomnia.

    This study investigated the psychological and physiological relaxation effects of the STRESS-CLEANER (SC-SX: Technos Japan Co., Ltd.). The participants were 44 healthy adults (20 men and 24 women, mean age: 34.14±11.58) who watched two music videos using the SC-SX. The Profile of Mood States-Brief Japanese Version (POMS: Yokoyama, 2005) was used to measure psychological variables and measurements were made at 3 time periods: baseline (T1), after watching video A (T2), after watching video B (T3). POMS consists of six subscales: Tension-Anxiety (T-A), Depression (D), Anger-Hostility (A-H), Vigor (V), Fatigue (F), and Confusion (C). Total Mood Disturbance (TMD) was calculated by subtracting V from the total for the other subscale scores. The biological signals (Electromyography: EMG) was used to measure physiological variables of the participants. Signals were analyzed by Fast Fourier Transformation (FFT). The power level of the Muscle potential was recorded between 2Hz and 40Hz during the three time periods. After the recording, the biological signals were integrated and the mean value was displayed on a PC screen as the Numerical of biological signals (NB). To investigate changes of POMS and NB, one-way ANOVAs with a repeated-measures design were conducted. Results indicated the significant main effect of the time period (T-A, A-H, F, C, TMD: p<.001, V: p<.01, D: p<.05, NB: p<.10). Post hoc analysis of group differences using Bonferroni's test indicated the following: (1) between T1-2, TMD of POMS and all subscales decreased significantly (ps<.05), 2) between T1-3, TMD of POMS and all subscales other than Depression decreased significantly (ps<.01), 3) between T2-3, only Tension-Anxiety and NB decreased significantly (Tension-Anxiety: p<.01, NB: p<.10). These findings suggested the C-SX had the effects of promoting the relaxation response.

    Recent psycho-physiological studies have revealed close relationships between human mental stresses and secretion of hormones and/or immunological substances. However, a precise elaboration of fluctuations in the secretion of these biomarkers in the time series against stress; especially against a rather mild stressful task is not yet clearly illuminated. In this study, we used the cortisol, a major glucocorticoid, as a biomarker of mental stress for 1) illustrating the precise stress-response in the time series, and 2) investigating a congruity of cortisol as the biomarker for a mild mental workload. In the experiment, ten male university students were inscribed to conduct a simple, easy, and monotonous mental arithmetic task for about an hour with intermissions, so as to emulate a mild mental workload. As a developing result, salivary cortisol concentration depicted an accumulative increase during mild mental workloads, while no marked difference was obtained in the heart rate and its variability. It suggests the slow and long-lasting properties in the stress-response of the cortisol unlike as in autonomous nervous system indices, and therefore plausibly demonstrates the possible candidacy of cortisol as a biomarker for a mild mental load. Finally, the possible applications of cortisol for an array of biofeedback studies are discussed as that cortisol could be an alternative marker for evaluating the physiological effects driven by the series of biofeedback treatments, because of its sustentive stressresponse for a long time range and/or accumulative changing profile.

    The relation between empathy and psychophysiology was studied in 10 university students (4 men and 6 women). While viewing footage of a child playing, the students underwent ECG measurement and their reactions to the child's altering mood were monitored. Their autonomic nervous activity was assessed by heart rate variability (HRV) with spectral analysis and coefficient of variation (CV_<R-R>). Students' feelings toward the child in the video were assessed by multiple mood scale (MMS), and then child's feelings are assumed by the students. The results of MMS suggested that they felt "astonished" by the videotape of a child reacting with astonishment or "pleased" when they observed a child's pleasure. The CV_<R-R> were significantly increased while they were observing a child's astonishment. This study confirmed that for the students observing, their own moods were altered psychophysiologically to the same degree as that of the child in the video.

    The purpose of this study was to examine the psychophysiological response to performance of making string figures with one's fingers. 8 healthy females were played two tasks, one was easy task and the other was difficult task, and repeated for five minutes. EEG, the mood scale for measuring psychological arousal level and hedonic tone, the self-assessment (skillfulness, concentration, enjoyment) about each performance. The data of EEG, the mood scale, self-assessment were compared in 2 tasks. The results were as follows. (1) In parietal area, beta activities in easy task were decreased in comparison with difficult task for three minutes of the latter half. (2) In the mood scale for measuring psychological arousal level and hedonic tone, "low arousal and pleasurable" score in a difficult task was decreased in comparison with easy task. (3) In self-assessment, "skillfulness" score in easy task was higher than difficult task, "concentration" score in difficult task was higher than easy task. These results suggested that the enjoyment of a string figure was difficulty and feeling of skillfulness by repetition, and concentration and EEG activity in difficult task of string figures were maintained.

    In this paper, P300 was evaluated in competitive situation using a principal component analysis (PCA) to verify the results obtained from the analysis of the mean amplitudes. The P300 was elicited by presenting the results of competition, in which the subjects with high and low levels of competitiveness completed a reaction time task with a warning stimulus comprising visible or invisible opponents. Eight principal components, such as slow wave and PINV, were extracted, and the third component was identified as P300 since it peaked at approximate 300ms after the presentation of the competition results. The effects of subjects' competitiveness, opponent visibility, winning or losing, and topography were examined on the component scores which were considered to reflect the amplitude of P300. For subjects with high levels of competitiveness, P300 was larger under competitive situations with an invisible opponent than that in the case of a visible opponent. For subjects with low levels of competitiveness, P300 was larger and RT was shorter when competing with a visible opponent than in the case of an invisible opponent. These findings suggest that the high competitiveness subjects were actively processing information under competitive situations by distributing attentional resources, and that the arousal level of the low competitiveness subjects increased when they competed with a visible opponent. A larger P300 was generally observed in winning trials rather than in losing trials of competitive conditions, and this indicates that the task in competitive situations was performed with the aim to win. In addition, the topographical distribution was more central than parietal and more midline than left hemispherical, as had been reported. The findings of this study supported the previous studies and found new characteristics of cognitive activity in competitive situations.

    [Purpose] We reported about a physical acoustic tinnitus treatment using biofeedback therapy. Firstly, a phase reversal of patient's subjective sound was made. Secondly, it was loaded to the ear having tinnitus and its tinnitus reducing effect was evaluated. [Method] 1) We prepared two tinnitus mimic models for healthy volunteer: Inner ear model (Ipsi model) and brain auditory center model (Contra model). Two imaginary tinnitus sounds (500Hz and 2000Hz) were loaded to each model and Auditory Brainstem Response (ABR), delay time of V wave was recorded. 2) Two subjects without underlying disease were tested the physical acoustic tinnitus treatment using biofeedback therapy. Tinnitus was evaluated by the interview sheet, tinnitus Handicap Inventory and Visual Analog Scale. (VAS) [Results] 1) In subject case 1, the tinnitus sound reducing effects appeared at delaying time 16.0ms for phase reversal. In subject case 2, the tinnitus reducing effects appeared at delaying time 29.0ms and 18.0ms for phase reversal. It was confirmed that the tinnitus reducing effects had appeared just 10 minutes after phase reversed sound loading in both subjects (VAS evaluation). [Conclusion] These results might have a clinical potential as a new tinnitus therapy.

    The case is a woman in one's thirties. The chief complaint is headache. The migraine without aura (non-responder to triptan, with allodynia) after a traffic injury was centers of the sickness. At first, awareness and the expression of feelings are difficult, and the awareness of the bodily feeling has decreased. Then, Psychophysiological Stress Profile (PSP) was enforced as an evaluation of an objective psychophysiological index. As a result, an excessive reaction of the finger blood volume pulse and the symptom reproduction after the stress were admitted with the stress. As a result, the understanding of awareness to the dissociation of a subjective symptom and an objective psychophysiological index evaluation and the mind-body correlations was obtained. The awareness of the bodily feeling deepened as the tiredness feeling was felt along with it, and it came to have the aura before the headache attack. Taking the ergotamine at the stage of the aura decreased the frequency of the headache sharply.

    This study was intended to review the psychological and physiological changes acquired from heartbeat biofeedback combined with breathing exercises. In this study, next three experimental conditions were set. Control condition (eyes closed resting state), regular condition (eyes closed, listening to heartbeat sound and try to expand the heartbeat, no breathing exercises), respiration condition (eyes closed, listening to heartbeat sound and try to expand the heartbeat, with breathing exercises). To compare each of these experimental conditions, as psychology index Two-Dimensional Mood Scale (TDMS) and introspective report, as physiology index count of respiration, electrocardiogram R-R interval were chosen as barometer. Furthermore, Lorenz plot was calculated from electrocardiogram R-R interval. As result of inspection, three major differences were found out between three conditions. (1) By TDMS, during mid experiment in regular condition and respiration condition, positive alertness enhanced. (2) In respiration condition, count of respiration decreased during mid experiment. (3) By Lorenz plot, regular condition showed increase in cardiac sympathetic nerve activity during post experiment. In conclusion, when BF was intended for inexperienced subject to relax, effort to expand heartbeat using BF with breathing exercises was more effective than without breathing exercise.
