Singing Bowls

Introduction Sound vibrations have a profound impact on the body and the mind with evidence confirming reduced anxiety and increased wellbeing. The likely reason for driving the benefit is relaxation. The Himalayan Singing Bowls, used for therapeutic intervention to enhance the individual’s emotional & physical wellbeing, may facilitate faster and deeper relaxation as compared to simple, supine relaxation. Aim of the Study The study aimed to validate the hypothesis that short 20 minutes sessions to relax with the help of the Himalayan Singing Bowl (HSB) could provide better depth of relaxation as compared to Supine Silence (SS) based on the objective assessment of physiology parameters i.e. Stress Index & Heart Rate Variability (HRV). Methods Seven metal Himalayan singing bowls were used in a particular sequence learned from an expert teacher for 16 subjects. The SS group consisted of 17 subjects. The HRV data was measured by the Emwave Pro device and analyzed using Kubios HRV Premium software. The analysis compared key HRV parameters within and between the groups. Result Overall, as expected, both groups achieved relaxation as measured by changes in HRV parameters. However, further analysis confirmed a more consistent relaxation, as measured by a statistically significant reduction in stress index and an increase in HRV, for HSB group. The HSB group achieved more consistent depth of relaxation during each subsequent 5 minutes interval throughout the session as compared to SS group. Conclusion The study confirms that singing bowls sessions can be leveraged as a tool for inducing good quality relaxation response (increased parasympathetic tone, reduced stress) to facilitate healing and energy recovery in just 20 minutes and achieve significant health benefits. More comprehensive studies must be conducted to further evaluate the findings with more sample size, different methods of relaxation and varied demographics.

Introduction Scientific evidence has demonstrated the psychological and physiological benefits of meditation. Sound vibrations also improve emotional wellbeing while enhancing the physiological parameters. There is an opportunity to explore the psychological and physiological benefits of Himalayan Singing Bowls (HSB) sound bath meditation, i.e. meditation assisted with sound vibrations. Aim of the Study The study explored changes in mood and Heart Rate Variability (HRV) parameters after a HSB Sound Bath Meditation on healthy individuals. The primary objectives of the study were to understand if a 40 minute long seated HSB Sound Bath Meditation results in significant improvement (a) in positive affect and negative affect, as measured by Positive And Negative Affect Scale (PANAS) and (b) in physiological parameters, as measured by Heart Rate Variability. The secondary objective of the study was to understand the impact on various moods as measured by Profile Of Mood States (POMS) Survey. Methods The psychological parameters included changes in Positive and Negative Affect (measured on 77 individuals using PANAS) and changes in specific, positive and negative moods (measured on 17 individuals using POMS) before and after the meditation session. The physiological parameters included HRV parameters such as Heart Rate (HR), Stress Index (SI) and Root Mean Square of Standard Deviation (RMSSD) measuring during the entire session on 15 individuals using the EmWave Pro device. HRV data analysis was conducted with Kubios HRV Premium and all the data was analyzed using paired T-Test. Results All the subjects after meditation showed statistically significant improvement in Positive Affect (mood) and a reduction in Negative Affect (mood). The HRV parameters showed a trend demonstrating overall relaxation with a statistically significant reduction in HR, Stress Index and an increase in RMSSD in the last 5 minutes as compared to the first 5 minutes. Consistent with changes in positive, negative mood and HRV, all the participants showed statistically significant reduction in tension, anger, fatigue, depression and confusion. In terms of positive mood, there was a statistically significant improvement in esteem related affect and an increase (but not statistically significant) in vigor. Conclusion The findings demonstrate that seated HSB Sound Bath Meditation session has a positive impact on the mood related measures. The physiological changes measured during the meditation using HRV parameters indicated a consistent reduction in Heart Rate throughout the meditation and a reduction in overall sympathetic tone and an increase in parasympathetic tone. Thus, HSB can be used to improve both psychological and physiological parameters even after one 40 min session. Future work in this area could explore comparison with a control group and a longer study duration consisting of multiple sessions.

Addiction is a devastating disease of the body, the mind, and even the personality. Recent research shows that heart rate variability biofeedback can help the alcoholic/addict recover in three crucial ways, namely (1) treating the associated comorbidities (depression, anxiety, chronic pain), (2) treating the physiology around craving, and (3) returning to a loving and nurturing relationship with one's own body instead of an abusive and exploitive one.

The sustainability of the development of society depends and is secure by the safety of health of human capital. The article presents the results of a study of gender differences in adaptive reactions of students in the development of educational innovations using the non-invasive method of heart rate variability. Comparative analysis of heart rate measurements among the surveyed students showed that both boys and girls had tachycardia during the lessons. In boys, an increase in the stress index revealed that was reliably associated with the tension of the parasympathetic system, and in girls - the sympathetic system of autonomic regulation of heart rhythm control. A wide individual range of adaptive reactions of the cardiovascular system of young men and women to the impact of ICT revealed. The data obtained more indicative of biological (sex) differences in adaptive responses in the implementation of information technology in education. Our research has shown gender differences in adaptive responses. We observed a significant correlation between stress and the reaction of the autonomic nervous system. It is necessary to prevent the disturbance of the adaptive of the body. Therefore, we must create a safe environment for the health of students. It is desirable to reduce the time spent in the information space (up to 80 minutes, followed by a break). Since the research conducted on a small sample and one educational institution, it is necessary to research this issue on a larger representative sample.

The Impact

Heart rate variability (HRV) biofeedback (BFB) can be used to reduce activation of the sympathetic nervous system (SNS) and increase activation of the parasympathetic nervous system (PNS). A growing body of research suggests that increased arousal of the SNS contributes to the sustained state of postconcussion syndrome (PCS). It has also been postulated that underactivation of the PNS may also play a role in the postinjury state of autonomic dystonia, wherein the autonomic nervous system is in a state of imbalance and does not return to normal. In addition to autonomic imbalance, patients who are generally advised not to engage in physical exertion until asymptomatic from concussion, are known to experience secondary symptoms of fatigue and reactive depression. Recent research has established that such symptoms can delay the recovery from concussion indefinitely. By addressing both autonomic dysfunction and the secondary symptoms of depression and anxiety, HRV BFB may be an effective treatment for PCS by strengthening self-regulatory control mechanisms in the body and improving autonomic balance. Recent studies have suggested that HRV BFB has a positive impact in reducing stress and anxiety among athletes, and concussed athletes with higher perceived control over their symptoms have been shown to have faster recoveries post-injury. The primary purpose of the following case study was, therefore, to assess the feasibility of implementing HRV BFB with a concussed athlete suffering from postconcussion syndrome (PCS). The second objective was to prospectively examine the impact of ten weeks of HRV biofeedback on refractory postconcussion symptoms. During this pilot case study, the athlete attended 10 weekly sessions of HRV BFB, according to the protocol set forth by Lehrer, Vaschillo, and Vaschillo (2000). After 10 weeks of HRV biofeedback, the athlete exhibited clinically significant improvements in total mood disturbance, postconcussion symptoms, and headache severity. The results suggest that HRV BFB may be a useful adjunctive treatment for PCS, associated with increases in HRV and enhanced cardiovagal activity. Given these findings, a randomized controlled trial is warranted.

BACKGROUND: It is important to identify the risks of developing somatic disorders, for further clarification by laboratory and instrumental diagnostic methods. An objective assessment of the effectiveness of the medical and psychological rehabilitation (MPR) of a serviceman is important. AIMS: The aim of the study is to determine the informative value of the Diamed-MBS hardware and software complex as a method of preclinical detection of pathological conditions by assessing heart rate variability (HRV), electrosomatography, bioelectrography (BEG), as well as the psychosomatic context of complaints and identified deviations. MATERIALS AND METHODS: Along with the methods of the Diamed-MBS agro-industrial complex, the MPR program of military personnel included a regulated scope of measures: examination for UPFT-1/30 "Psychophysiologist" (simple visual-motor reaction and variational cardiointervalometry); registration of the levels of "energy potential" and stress background by gas-discharge visualization on the pulse analyzer "GRV-Express", determination of the compositional composition of the body by bioimpedance measurement on the analyzer "Tanita BC-532". The automated system of assessment in points (APC) allows for differentiated diagnostics of the somatic and psychoemotional profile of military personnel who arrived at the MPR; to personalize the rehabilitation program; to evaluate the effectiveness of the MPR program. The data of a group of 85 military personnel undergoing MPR were processed in the Statistica 10 (StatSoft Inc., USA). RESULTS: In the branches of the Federal State Budgetary Institution SKK "Privolzhsky" of the Ministry of Defense of the Russian Federation ("Volga Clinical Sanatorium", "Chebarkulsky Sanatorium", "Yeltsovka Sanatorium") within the framework of the psychotherapy office (psychologist's office) with the category of MPR, work was carried out on the Diamed-MBS hardware and software complexes for 9 months. This allowed for a short examination time (up to 20 minutes) to conduct an objective assessment of the psychosomatic state of a person: respiratory, digestive, immune, genitourinary, musculoskeletal, cardiovascular, endocrine systems, as well as the general state of the body and psychological status. After the course of MPR, the improvement of the indicators of the condition of military personnel was noted to a greater extent due to the indicators according to the survey data (Questionnaire 1, 2) (p 0.000) (the subjective component of the study), which ultimately reflected the improvement of the integral indicator (Integral 1, 2) (p 0.007). Changes in the psychoemotional (Psychoemotional 1, 2) and somatic state (Soma 1, 2) were not statistically significant (p 0.05). CONCLUSION: The restoration of the psychoemotional background and the necessary training in stress resistance skills requires a revision of the duration of the MPR by military personnel. The advantage of the Diamed agro-industrial complex is the arrangement of three diagnostic complexes in one device: for determining the parameters of heart rate variability, electro-tomography, bioelectrography; in the mode of express diagnostics, the determination of the state of the body in the range "healthy-practically-healthy-weakened-premorbid state-sick-critical condition". The possibility of creating a single information and analytical center for processing the final protocols of the examination of military personnel under the MPR program in the CCM sanatoriums.

Relevance . Maintaining the health of migrants while adapting to the new climatic and geographical conditions of residence is an urgent task. The impact of non-specific factors on the body of migrants in new climatogeographic conditions leads to the strain of regulatory and adaptive mechanisms, and in extreme cases to their failure. Objective - to determine the features of heart rate variability in young Tajiks, depending on the type of temperament living in Krasnoyarsk for more than a year. Materials and Methods: A study of heart rate variability in 63 Tajiks aged 18-40 years with different types of temperament, living in Krasnoyarsk for more than a year, was conducted. The types of temperament were determined by indices in accordance with the method of identifying VP-types of temperament according to E.Yu. Petrosyan, Yu. I. Savchenkov. The following indicators of heart rate variability (HRV) were evaluated: heart rate, the power of the high-frequency, low-frequency and very low-frequency spectrum (BV, MV-2, MV-1) of the HRV component, the voltage index of regulatory systems (IN), the centralization index (CI) and the activity index of regulatory systems. To assess the statistical significance of the differences between the samples, the Students criteria were used. Results and Discussion. It was revealed that migrants with an intense type of temperament after moving to a new place of residence increased the indicators of heart rate, BV and IN. At the same time, in the studied groups with a calm and adequate type of temperament, the power of BV was significantly reduced, with an increase in heart rate and CI. The conclusion is made about the influence of typological features of temperament on HRV indicators, when adapting to new climatogeographic living conditions. Individuals with an adequate type of temperament demonstrate the normal functioning of the adaptive capabilities of the body. In individuals with the calm type, an increase in the tension of the regulatory mechanisms was revealed. Conclusion . Significant changes in HRV are demonstrated by migrants with an intense type of temperament, in particular, they are characterized by a high voltage of regulatory mechanisms.

AbstractIntroduction. The aim of the study was to determine the effect of personality-oriented physical rehabilitation programs on the heart rate variability in women with post-mastectomy syndrome. Methods. The following methods were applied: theoretical analysis of scientific and methodologic literature data, heart rate variability analysis, and mathematical statistical methods. The subjects of the study were 50 women with late symptoms of post-mastectomy syndrome. The study was conducted during the ambulatory rehabilitation stage after Madden radical mastectomy. All the indicators of the heart rate variability were equivalent in the main and comparison groups at the beginning of rehabilitation. The impact of training was examined every 6 months over the course of a year. Results. Measurements were taken three times: at the beginning of rehabilitation and after 6 and 12 months. It was found that most of the investigated parameters of heart rate variability in both groups steadily improved during the year of rehabilitation. The average values of stress index and amplitude of mode after 12 months of rehabilitation were lower in the main group than in the comparison group but the values of the standard deviation of normal-to-normal intervals and the very low-frequency component of the spectrum were better by 6.48 ms (p < 0.05) and 203.29 ms2 (p < 0.05), respectively. Conclusions. The personality-oriented programs of physical rehabilitation were effective in augmenting heart rate variability and restoring autonomic balance in patients with post-mastectomy syndrome.

Determining the maladaptation and adaptive capabilities of the body, in particular the cardiovascular system of volleyball player is currently advanced in sports medicine. The aim of the work is to establish correlations between cardiointervalographic indicators and parameters of external body structure in volleyball players of mesomorphic somatotype of juvenile age. The study involved 24 volleyball players aged 17 to 21 with a high level of sportsmanship and more than 3 years of experience. We conducted a study of heart rate variability on the cardiac computer diagnostic complex "OPTW" according to the recommendations of the European and North American Cardiac Association (1996). Indicators of autonomic homeostasis according to Baevsky, variation pulsometry, statistical and spectral cardiointervalographic parameters were determined. Anthropometry was performed by the method of Bunak (1941), somatotypological study – by the calculated modification of the method of Heath-Carter (1990), determination of the component composition of body weight by the method of Matejko (1992), correlation analysis by the method of Spearman was performed in the package "STATISTICA 5.5". Mesomorphic volleyball players were found to have the highest number and strength of reliable correlations with anthropo-somatotypological parameters, most of which were inverse and medium strength. Statistical, spectral parameters of heart rate variability and indicators of autonomic homeostasis with indicators of external body structure had few significant correlations. The girth of the hand in mesomorphic constitution volleyball players was statistically significantly related to the value of all statistical parameters and indicators of autonomic homeostasis by the method of Baevsky. According to the results of correlation analysis, we can assume that in volleyball players of mesomorphic somatotype with increasing the size of the mesomorphic component of somatotype, longitudinal, circumferential sizes and diameters of chest, arm, leg, neck will increase the impact on heart rate variability of the parasympathetic autonomic system.

AbstractThe vagus nerve is the largest autonomic nerve, innervating nearly every organ in the body. “Vagal tone” is a clinical measure believed to indicate overall levels of vagal activity, but is measured indirectly through the heart rate variability (HRV). Abnormal HRV has been associated with many severe conditions such as diabetes, heart failure, and hypertension. However, vagal tone has never been directly measured, leading to disagreements in its interpretation and influencing the effectiveness of vagal therapies. Using custom carbon nanotube yarn electrodes, we were able to chronically record neural activity from the left cervical vagus in both anesthetized and non-anesthetized rats. Here we show that tonic vagal activity does not correlate with common HRV metrics with or without anesthesia. Although we found that average vagal activity is increased during inspiration compared to expiration, this respiratory-linked signal was not correlated with HRV either. These results represent a clear advance in neural recording technology but also point to the need for a re-interpretation of the link between HRV and “vagal tone”.
