This case study illustrates both methodology and results from a patient undergoing training in capnometry-assisted respiratory training (CART). CART is a 4-week training aimed at normalizing basal and acute levels of end-tidal carbon dioxide (PCO(2)) using a portable capnometer. In the presented case, basal levels of PCO(2) increased from hypocapnic to normocapnic range over the course of treatment. Improvements were accompanied by improvements in lung function and reductions in diurnal lung function variability. Improvements remained stable throughout follow-up.

Participants from a treatment study (N = 45) were selected according to post-treatment results and divided into two groups: the unsatisfactory treatment outcome group (UTO, N = 10) and the satisfactory treatment outcome group (STO, N = 10). The differences between these two groups prior to receiving exposure therapy were analyzed at the behavioral, physiological, and cognitive levels. The UTO participants had been avoiding flying longer than the STO phobics. Following Thayer and Lane's neurovisceral model of emotion regulation, heart ...

Twelve patients with a torn ACL were randomly assigned to a MI or control group, who both received a series of physiotherapy. Electromyographic activity of the quadriceps, pain, anthropometrical data, and lower limb motor ability were measured throughout a 12-session therapy. The data provided evidence that MI elicited greater muscle activation, even though imagery practice did not result in pain decrease. Muscle activation increase might originate from a redistribution of the central neuronal activity, as there was no anthropometric change in lower limb muscles after imagery pr...

Data was examined for 182 consecutive admissions to a psychology clinic to determine the relationship of self-rating of emotional and physical discomfort to one another and of the emotional self-rating to the clinician rating of general functioning (GAF). As expected, patients' ratings of their emotional discomfort were significantly higher than ratings of their physical discomfort (t = 9.077, p < .001). Emotional SUDS were significantly and negatively related to clinicians' GAF r...

Depressed individuals have high levels of cortisol, and exhibit an attentional bias toward a depression-related stimulus and impaired processing speed and executive attention, which are components of attentional function. Therefore, the study tested the hypotheses that an acute increase in cortisol in response to a stressor is associated with attentional bias toward a depression-related stimulus and impaired processing speed and executive attention. Thirty-six participants were administered the dot-probe task for the measurement of attentional bias toward a depression-related stimulus and the Trail Making Test A and B for the measurement of processi...

The protocol detected 90-100% of these subjects with <10% false positives. We have also shown that Reaction Time (RT) to the first trial stimulus is increased (group effect) with countermeasure use. We also reported a new P900 component associated with countermeasure use when 2 of 4 irrelevants are countered. In the present study we report data from 4 new groups and re-present for comparison previously collected data to have 7 groups: an innocent control, a guilty group not using countermeasures, and 5 guilty/countermeasure groups who counter from 1 to all 5 stimuli presented (4 irrelevants plus a probe)...

Electroencephalography of patients with TS has revealed reduced Sensorimotor Rhythm (SMR) and excessive fronto-central Theta activity, that presumably underlie motor and cognitive disturbances in TS. Some evidence exists that neurofeedback (NFB) training aimed at enhancing SMR amplitude is effective for reducing tics. The present report is an uncontrolled single case study where a NFB training protocol, involving combined SMR uptraining/Theta downtraining was delivered to a 17-year-old male with TS. After sixteen SMR-Theta sessions, six additional sessi...

In particular, our results indicate that decisions (based on high and low, but not intermediate levels of uncertainty) made under stress (confirmed by skin conductance measures) are associated with increased confidence when outcome probabilities are incompletely known (20% residual uncertainty). A different pattern was found when outcome probabilities were completely known (0% residual uncertainty). Here, stress led to decreased decision confidence when decisions were associated with intermediate levels of uncertainty but had no effect in case of high and low levels of uncertainty.

Neurofeedback (NFB) is a little used, psychophysiological treatment with demonstrated usefulness for treating insomnia. Our objective was to assess whether two distinct Z-Score NFB protocols, a modified sensorimotor (SMR) protocol and a sequential, quantitative EEG (sQEEG)-guided, individually designed (IND) protocol, would alleviate sleep and associated daytime dysfunctions of participants with insomnia. Both protocols used instantaneous Z scores to determine reward condition administered when awake.

Our hypothesis is that a large range of strong negative emotional consequences, including those induced by economic pressure, are associated with the decision to revise the flight plan and favor PCE. We investigated the economic hypothesis with a simplified landing task (reproduction of a real aircraft instrument) in which uncertainty and reward were manipulated. Heart rate (HR), heart rate variability (HRV) and eye tracking measurements were performed to get objective clues both on the cognitive and emotional state of the volunteers.

We sought to determine whether the relationship between self-regulation and heart rate variability (HRV) could be replicated and extended. We hypothesized that baseline HRV would predict persistence on an anagram task, and that under conditions requiring greater self-control, HRV would increase. Two groups were given the same set of difficult and unsolvable anagrams. To induce self-regulatory fatigue, the suppression group was asked to try to not think of a white bear while the expression group was asked to try to think of a white bear.

We hypothesized that daily device-guided slow breathing may lower blood pressure in patients with hypertension and obstructive sleep apnea (OSA). In this one-arm pilot study, we enrolled 25 subjects with hypertension and OSA. Subjects were asked to perform device-guided paced respiration 30 min a day for 8 weeks. Our primary outcome was change in office systolic and diastolic blood pressures from baseline to 8 weeks. Twenty-four subjects completed the study.

Precisely what is regulated when mood regulation occurs is dependent on what "makes up" mood. The purpose of this study was to evaluate whether perceived mood regulation ability can predict regulation of affect during task engagement and whether affect regulation is specific to valence or arousal. Measures of positive affect, negative affect, and frontal area sEMG (as a measure of arousal) were obtained from a sample of one hundred twenty-four participants categorized by their self report as possessing low or high mood regulation ability.

The current study examined the effects of routine external hand warming on the PSH intensity of a 16-year-old male referred for management of recurrent headaches. The participant, Michael, alternated periods of non-warming with periods of daily external hand warming, and an ABAB design was used to evaluate the impact of hand warming on PSH intensity. Results indicate that clinically significant symptom reduction was obtained with implementation of external hand warming.

HRV biofeedback is a newly developed approach that may have some use for treating the array of disorders in which HRV is relatively low. This review critically appraises evidence for the effectiveness of HRV and related biofeedback across 14 studies in improving (1) HRV and baroreflex outcomes and (2) clinical outcomes. Results revealed that HRV biofeedback consistently effectuates acute improvements during biofeedback practice, whereas the presence of short-term and long-term carry-over effects is less clear. Some evidence suggests HRV biofeedback may result in long-term carry-over effects on baroreflex gain, which is an area most promising for future investigations....

This study's findings provide physiological evidence of RSA feedback effect and suggest that RSA training may decrease arousal by promoting an increase of alpha band frequencies and decrease in beta frequencies overall and in areas critical to the regulation of stress.

However, to date, this adjunct treatment has not been rigorously tested against non-contingent (placebo) feedback. Forty-two patients with chronic low back pain were randomized to either RFB or non-contingent RFB. Both groups performed a daily 30-min home training for 15 consecutive days. A respiratory associated relaxation index (RI) was measured. Pain levels and a somatosensory profile were assessed before and after intervention. Additionally, pain levels were assessed 3 months after the end of intervention. Secondary outcome parameters included daily functioning, psychopathology, and suggestibility.

Twenty children with FAP and 10 children without FAP between the ages of 5 and 17 years old were compared on autonomic regulation using an ambulatory system at baseline and 8 weeks later. Children with FAP participated in 6 sessions of HRV biofeedback aimed at normalizing autonomic balance. At baseline, children with FAP appear to have more autonomic dysregulation than children without FAP. After completing HRV biofeedback, the FAP group was able to significantly reduce their symptoms in relation to significantly increasing their autonomic balance.

Empirical validation of these concepts is in its beginning stages and still hampered by problems with measurement. A promising avenue and foundation for validity testing is the demonstration that acupoint activity can be reliably measured via determination of electrical resistance at well-defined body surface points. In this article, efforts are described to maximize measurement reliability; we tested a variety of protocols to determine which method of data aggregation is associated with maximal reliability.

Often it is assumed that the reader has detailed knowledge of these terms. The difficulty begins when seemingly familiar terms are used as a basis for an in-depth explanation of the process of electromyography. For example, the concept of impedance is based on three building blocks of electricity: current, voltage and resistance. The term "impedance" is found in every manual for biofeedback equipment with the suggestion that the electrode site be kept "low" and the encoder input "high". A little electrical knowledge can explain why this is so and in the process formulate a more thorough understanding of the equipment used everyday with a client.

These improvements relate mostly to evaluations conducted in the high frequency beta range (21-30 Hz) evaluation and in single Hz bins, which more specifically address which frequencies need to be trained to most quickly and effectively normalize their dysfunctions and remediate their difficulties. Use of the modular activation/coherence model (Walker et al. in J Neurother 11: 25-44, 2007) provides a framework for correcting the slow or fast modular dysfunctions, as well as normalizing connectivity using coherence training.

As long as the operator is a key agent in charge of complex systems, the definition of metrics able to predict his performance is a great challenge. The measurement of the physiological state is a very promising way but a very acute comprehension is required; in particular few studies compare autonomous nervous system reactivity according to specific cognitive processes during task performance and task related psychological stress is often ignored.

The fact that most patients qualify for dual diagnoses, with co-morbid psychiatric and medical conditions present, complicates the ability of clinicians to estimate what electrophysiological patterns may be associated with symptoms. In such cases treatment planning is characterized by a great deal of guesswork and experimentation. Peer reviewed publications have documented that neurofeedback treatment can sometimes ...

Nineteen children were randomized into an experimental group receiving qEEG based neurofeedback (n = 10) and a control group (n = 9). Both groups also received remedial teaching. The experimental group improved considerably in spelling (Cohen's d = 3). No improvement was found in reading. An indepth study of the changes in the qEEG power and coherence protocols evidenced no fronto-central changes, which is in line with the absence of reading improvements. A significant increase of alpha coherence was found, which may be an indication that attentional processes accoun...

To measure autonomic regulation, heart rate data was collected before and after the participant rode a stationary bike for one mile. We found that abuse history was associated with less vagal regulation of the heart (i.e., respiratory sinus arrhythmia) and an inability to rapidly re-engage vagal regulation immediately following mild exercise to support a calm physiological state. These findings are consistent with clinical impressions that abused individuals may have a lower threshold to express fight/flight behaviors in re...

The aim of this study was to clarify the common pathophysiology of FSS, especially the relationship between hypothalamic-pituitary-adrenal (HPA) axis function and psychological characteristics of patients with FSS. The subjects were 45 patients with FSS and 29 healthy controls. Salivary free cortisol was measured in the morning, and psychological tests examining depression, anxiety and quality of life (QOL) were performed on the same day.

Symptoms were sub-threshold for major depressive disorder or acute stress disorder. Mood and anxiety symptoms responded to traditional therapy techniques, but problems with insomnia remained. The patient was given a portable biofeedback device that employs an infrared sensor photoplethysmograph to measure heart rate variability (HRV) from peripheral finger pulse. One week later, sleep was significantly improved. Symptom improvement lasted to at least 6 weeks while in theater.

Specifically, we examined whether a symptom based approach or an assessment/connectivity guided based approach was more effective. Although both methods demonstrated significant improvement in symptoms of autism, connectivity guided neurofeedback demonstrated greater reduction on various subscales of the Autism Treatment Evaluation Checklist (ATEC). Furthermore, when individuals were matched for severity of symptoms, the amount of change per session was significantly higher in the Coben and Padolsky (J Neurother 11:5-23, 2007) study for all five measures of the ATEC.

The first set has to do with psychophysiological measurement in the CIT (e.g., specific sensitivity testing in lab vs. field). Secondly, I consider the relationships between the psychological process of deception and the CIT. Thirdly, I consider the problem of laboratory-to-field generalization of the CIT, a consideration that includes a discussion of whether the lab/field differences are merely quantitative or actually qualitative. Finally, I discuss theories concerning the hypothetical mechanisms underlying the CIT, and argue that while the purely cognitive, Soko...

We found that in forensic settings PDD provided substantial improvements in information gain over unassisted laypersons across nearly the complete range of the base rate of guilt. This was true for accuracy estimates based on laboratory and field data.

Mere recognition was isolated by having participants respond based on an irrelevant dimension of the stimuli. In Experiment 1 stimuli consisted of familiar and unfamiliar faces, with a dot placed on the left or the right cheeck. Participants responded according to dot location. In the second experiment, participants were presented with autobiographical information, alternated with irrelevant stimuli, while instructed to respond based on the case of the stimuli. Results showed that with both familiar faces, and autobiographical information, mere recognition was sufficient to elicit a P300.

Here, we introduce a behavioral paradigm that could be used to reveal concealed information by exploiting the link between concealed information and attentional processes more directly. This novel paradigm is based on the attentional blink phenomenon in which detection of a stimulus reduces detection accuracy rates of subsequent target stimuli within a 200-500 ms time window. We hypothesized that a well-known face used as a...

When subjects use countermeasures to all irrelevant items in the test, the probe P300 is increased rather than reduced (as it was in previous P300-based deception protocols), allowing detection of countermeasure users. The current experiment examines the role of task demand on the complex trial protocol by forcing the subject to make countermeasure-like response to stimuli. Subjects made either a simple random button response to both probe and irrelevant stimuli (experiment 1) or a more complex, assigned, button response to p...

To combat countermeasures, two covert respiration measures, hidden in the seat and back of the examination chair, were used in addition to the standard physiological measures (SCR, FPWL, RLL). Some guilty participants were trained to use either physical or mental countermeasures and apply them to distort the outcomes of the CIT. In the second phase of the experiment participants were detached from the standard polygraph devices and examined solely with the two covert measures.

The concealed knowledge test (CKT) focuses on participants' recognition of privileged knowledge rather than lying per-se and has been studied extensively using a variety of measures. A "guilty" suspect's interaction with and memory of crimescene items may vary. Furthermore, memory for crimescene items may diminish over time. The interaction of encoding quality and test delay on CKT efficiency has been previously implied, but not yet demonstrated. We used a response-time based CKT to detect concealed knowledge from shallow and deep study procedures after 10-min, 24-h, and 1-week delays. Results show that more elaborat...

Orienting theory has been proposed to account for concealed information testing. As orienting is characterized by heart rate deceleration, one would expect this type of heart rate response to concealed information. However, with some exceptions, an initial heart rate acceleration to concealed information is typically observed. In the present paper, we examine the role of verbalization to explain the mixed pattern of heart rate changes. Using a within-subjects design, 30 participants were asked to either remain silent or to give an overt verbal response ("yes"/"no") to concealed autobiographical and control information.

The experimental group received training in emotion self-regulation techniques intended to reduce stress and health risk factors. Practice of the techniques was enhanced by heart rate variability feedback, which helped participants learn and sustain use of the self-management tools. Measures of physiological stress included cortisol, DHEA, cholesterol, triglycerides, fasting glucose levels, 10-min resting electrocardiogram, heart rate variability, and blood pressure. Three psychological questionnaires assessed emotional stress and work-related variables. There were significant improvements in the experimental group in choles...

Appl Psychophysiol Biofeedback. 2009 Mar 24; Authors: Santarpia A, Blanchet A, Mininni G, Kwiatkowski F, Lindeman L, Lambert JF In this paper we examined the influence of repetition of weight-related sentences on the involuntary pressure forces of the forearms, when in a relaxed state. These forces were involuntary oscillations, exerted by muscle movements of the breathing-cycle and muscle movements of the arm on force sensors. We constructed a linguistic bio-mechanical system (Ablasmi), where in each arm of a padded relaxation chair contained special sensors that were specifically designed to detect the pressure forces of each forearm while participants listened to the specific recorded weight-related sentences.

Deviations in QEEG patterns from the normative group are the basis for an intervention plan. While QEEG patterns, obtained under an eyes closed, resting condition, provide information about deviations at rest, QEEG patterns obtained while the patient engages in cognitive tasks reflect specific deficiencies in brain functioning.

If detection of respiratory loads is a function of the background load, then pressure-threshold type inspiratory muscle strength training (IMST) would affect the detection of DeltaPT but have less effect on detection of DeltaR. DeltaR and DeltaPT detection and ventilatory responses were measured in healthy volunteers. IMST consisted of 4 sets of 6 breaths per day for 4 weeks, at 75% of maximal inspiratory pressure (MIP).

A fast fourier transformation was performed on the quantitative electroencephalogram (qEEG) and the performance record of each participant (N = 62), producing an individual periodogram for each outcome measure. An average periodogram was then produced for both qEEG and performance by combining (averaging) the amplitudes associated with each periodicity in the 62 original periodograms. Periodicities ranging from 1.00 to 2.00 min and from 4.70 to 5.70 min with amplitudes greater than would be expected due to chance were retained (Smith et al. 2003). The results of the...

After a brief introduction to TMJD, the article presents data, largely derived from work carried out in my laboratory, that address four questions: (1) What are the consequences of parafunctional activities? (2) Do TMJD patients engage in parafunctional activities? (3) Why are TMJD patients unaware of these activities? and (4) What are the implications of these findings for treatment? The findings suggest that low-level parafunctions increase pain in otherwise pain-free individuals and can produce symptoms sufficiently severe to meet the diagnostic criteria for TMJD diagnoses of myofascial pain and/or arthralgia.

The technique applied was the one advocated by the hatha-yoga system. Nine yoga instructors-five females and four males, mean age of 44 +/- 11, 6, were subjected to analysis of the gases expired during three distinct periods of 30 min: rest, respiratory exercises and meditative practice. A metabolic open circuit computerized system was applied (VO2000, MedGraphics-USA).

About 12 subjects altered their breathing and posture while 2 examiners assessed their breathing using the MARM. Simultaneous measurements with RIP were taken. Inter-examiner agreement and agreement between MARM and RIP were assessed. The ability of the measurement methods to differentiate between diverse breathing and postural patterns was compared. High levels of agreement between examiners were found with the MARM for measures of the upper rib cage relative to lower rib cage/abdomen motion during breathing but not for measures of volume.

There is no consistent evidence that EDR lability reflects dispositional or clinical anxiety. However, EDR lability appears to be related to individual differences in the overt expression of emotional and antagonistic impulses. Greater EDR lability is associated with a relatively undemonstrative and agreeable disposition, whereas greater EDR stability is associated with a relatively expressive and antagonistic disposition. The inverse relationship between EDR lability and the expression of emotional and antagonistic impulses suggests that EDR lability may reflect individual di...

Twenty-nine participants took part in the experiment. Visual stimulation with slides eliciting disgust was followed by subjectively pleasant music, sad music, and white noise in three consecutive sessions. The spectral power of the frontal and temporal EEG, skin conductance, heart rate, heart period variability, facial capillary blood flow, and respiration rate were recorded and analyzed. Aversive visual stimulation evoked heart rate deceleration, increased high frequency component of heart period variability, increased skin conductance level and skin conductance response frequency, decreased facial blood flow a...

A principal components analysis (PCA) was performed on the qEEG obtained from participants during a continuous performance test. Measures of sensitivity (proportion of correctly identified correct responses, or hits) and specificity (proportion of correctly identified incorrect responses, or misses) were calculated to assess the classification accuracy of each newly derived component. PCA solutions produced a right hemisphere component comprised of beta-wave activity measured from four unipolar sites (F8, C6a, C6, and T4) that appeared to be sensitive and specific to changes in human performance. Results pr...

It is possible that regular exercise of homeostatic reflexes helps depression even when changes in baseline HRV are smaller. A randomized controlled trial is warranted.

Five male (24.6(+/-0.9) years) and five female (22.2(+/-1.9) years) college students were selected as the subjects for this study. Two psychological tests were developed to measure the performance level of verbal cognition. The experiment consisted of two runs: one was a verbal cognition task, with normal air (21% oxygen) administered and the other was with hyperoxic air (30% oxygen) administered. The experimental sequence in each run consisted of Rest 1 (1 min), Control (1 min), Task (4 min), and Rest 2 (4 min). Blood oxygen saturation and heart rate were measured throughout the four phases. The results of the verbal behavioural analysis reveal that acc...

The QEEG was recorded with a Lexicor 1620 from 19 sites with appropriate controls for impedence and artifacts. A neurologist read the data for abnormalities and the QEEG was analyzed by mapping, single and multiple hertz bins, coherence, and statistical comparisons with a normative database. The session included a meditation baseline and tongue piercing. During the meditative baseline period the yogi's QEEG maps suggesting that he was able to lower his brain activity to a resting state. This state showed a predominance of slow wave potentials (delta) during piercing and suggested that the yogi induced a state that may be similar to those found when indivi...

Using a picture-viewing paradigm, the present study investigated differences between females with TTH and controls on physiological reactivity, affective valence and arousal, and oral motor habits. In addition, the concordance between EMG activity and self-reported oral habits (i.e., proprioceptive awareness) and EMG activity and self-reported affect (i.e., affective coherence) were measured using within-subject correlations per individual and then compared between groups. Data were analyzed for 27 TTH sufferers and 27 controls who completed a...

Self-reported mood (assessed by the Stress-Energy Checklist) at baseline was related to learning muscle relaxation induced by electromyographic feedback training during performance of a gross-motor task. Feedback training was provided either intermittently (Intermittent Feedback Task, IF, n=12) or continuously (Continuous Feedback Task, CF, n=9). Results reveal a negative correlation between the learning effect at short-term and energy dimension for the IF Task. It can be concluded that mood experienced prior to a learning task is relevant for the learning effect and this effect may be dependent on the schedule of feedback used.

Participants received HR feedback training during the presentation of a videogame, and transfer of training was assessed to a mental arithmetic challenge and handgrip task. Transfer of training was next assessed following training with the mental arithmetic challenge and handgrip task. HR responses to each training task with no HR feedback were assessed during a pre-treatment session, an immediate post-training period following training on each task, a short delay (1-2 days) po...

Patients were previously treated in physical or occupational therapy for head control, standing balance training, sitting and upper extremity use (brachial plexus injury). They then participated in a program that utilized multiple surface electromyography sites the use of which was rewarded with videos for performing the correct constellation of recruitment pattern (e.g., contracting some muscles while relaxing others). Onset of reward was calibrated for each patient and transfer of skill to outside the clinic was encouraged by linking a verbal cue to the correct motor plan. Four...

In two experiments we tested a biofeedback technique that recorded electromyographic (EMG) activity from a bipolar surface electrode placement over the right external intercostal muscles with visual signal feedback. Healthy participants were tested in their ability to alter the signal. Heart rate was measured continuously throughout training trials. In the second experiment, dyspnea was rated on a modified Borg scale after each trial. Participants were able to increase their EMG activity considerably while heart rate and dyspnea increased substantially. Changes in EM...
