Objective: To study the effect of hand tapping on the synchronization of the alpha rhythm in healthy adults. Materials and Methods: The study included 51 clinically healthy volunteers of working age. Results: We have shown that under the influence of wrist tapping in a state of sensory deprivation in healthy adults there is a statistically significant change in the peak frequency (p = 0.0006) and peak power of the alpha rhythm (p = 0.0003), but the width of the peak plateau remains unchanged (p = 0.2). This effect of wrist tapping indicates the potential for clinical use in JME, since it was previously shown that if the selected external frequencies enter into resonance with the neurons of the antiepileptic system, then an antiepileptic effect can be obtained.
Background. Non-pharmacological methods of palliative therapy for structural focal epilepsy (SFE) have been extensively investigated. Development of self-care methods based on behavioral psychotherapy and reference bioadaptation is a promising and economically justified approach.Objective: to present a clinical case of administering EpiTapp application based on the author-proposed wrist tapping method for palliative care in adult SFE.Material and methods. The author-proposed method of wrist tapping (RF patent No. 2606489 of 01.10.2017) for a smartphone Android OS application was used. Wrist tapping was performed during the period of aura and/or focal seizures (FS) in patients with SFE. Patients used the smartphone application as an element of emergency palliative therapy for SFE outpatient settings.Results. Patient L., 33 years old, suffering from SFE with frequent FS and bilateral seizures (BS), received duotherapy in the preoperative period. The woman used the EpiTapp application regularly that allowed to reduce FS rate by 65%, as well as prevent BS development without altering the antiepileptic therapy regimen.Сonclusion. The experience of using the EpiTapp application based on the author-proposed method of wrist tapping has demonstrated that it holds promise for SFE palliative therapy. The proposed technique requires additional research to confirm its effectiveness.
The objective of our review was to analyze studies of prevalence sleep disorders among medical workers during COVID-19 pandemic. Material and Methods — Overall, during the analyzed period, studying domestic and foreign databases, we identified 94 publications on the development of sleep disorders among medical personnel working during COVID–19 pandemic in 2000-2021. However, only 88 of these publications complied with the objective of the review. We included 75 full-text publications in this review. Results — Physicians and nurses during COVID-19 pandemic do not have the opportunity to take therapy aimed at combating the symptoms of sleep disorders, due to the need to maintain sufficient attention and the risk of developing excessive drowsiness while on duty in a COVID -19 hospital. The latter can have a negative impact on their professional activities. Thus, this problem certainly requires professional psychotherapeutic correction. Unfortunately, not all medical institutions have such specialists. Conclusion — Based on the literature review, we found out that health care workers have a high risk of developing sleep disorders. This can include violations of the circadian rhythm, a decrease in the quality and duration of night sleep, daytime hypersomnia caused by shift work in a hospital. An additional factor affecting the frequency and severity of sleep disorders in healthcare workers (physicians and nurses) is chronic stress, the importance of which has increased during the COVID-19 pandemic. Currently, the above problem has not been completely solved and requires research in this area and the development of new programs to help medical personnel.
Background: The aim of this study was to assess the effect of wrist tapping (WT), according to the author's method, on the synchronization of alpha activity in healthy adults and patients with juvenile myoclonic epilepsy (JME). Methods and Results: The study included 71 people of working age, including 51 clinically healthy volunteers (median age - 39[21;56] years) and 20 patients with JME (median age 27[23;35] years). Under the influence of WT in a state of sensory deprivation, statistically significant changes in the alpha peak frequency (APF) (P<0.001) and alpha power (AP) (P<0.05) were found in healthy adults. In JME patients, there were statistically significant changes in the APF (P<0.05) and AP (P<0.05), as well as a statistically significant increase in the ARW (P<0.05) after WT. WT, according to the author's technique, allows reducing the severity of alpha rhythm synchronization and leads to a shift in the peak frequency of the alpha rhythm in the occipital leads towards the alpha-2 sub-frequency range and a decrease in AP in both healthy volunteers and JME patients. At the same time, the alpha range width in the occipital leads is statistically significantly increased in JME patients. Conclusion: The nature of the change in the alpha rhythm, in comparison with the control, indicates the phenomenon of resonance with the frequency of the WT rhythm. The WT effect testifies to the prospects of the clinical application of WT in JME, since it was previously shown that if the selected external frequencies enter into resonance with the neurons of the antiepileptic system, then an antiepileptic effect could be obtained.
The aim of this study was to assess the dynamics of interhemispheric coherence (IC) as an indicator of integration of different areas of the brain and their participation in the performance of certain functions before and after wrist tapping (WT), using the author's method in juvenile myoclonic epilepsy (JME). Methods and Results: The study included 81 subjects of working age, including 51 clinically healthy volunteers (median age of 39[21;56] years) and 30 patients (median age of 27[23;38] years) with JME. Analysis of IC in the electrode pairs Fp1-Fp2, F3-F4, C3-C4, T3-T4 was performed using a computer encephalographic complex. A coherent EEG analysis was used to identify and evaluate the relationships between different areas of the brain. Based on the change in the coherence coefficients (CCs), the level of integrative activity of brain structures was quantified. In healthy volunteers, before and after WT, we observed a statistically significant decrease in CCs for the beta-1 band in the pairs Fp1-Fp2, F3-F4, and C3-C4 (P<0.05), while in the pair T3-T4, changes in CCs were not statistically significant (P>0.05). At the same time, a statistically significant decrease in CCs in the alpha band was found only in the frontal regions in the pairs Fp1-Fp2 and F3-F4 (P<0.05). No statistically significant changes were found in all the studied pairs in the theta band. When comparing CCs in JME patients in beta–1 and theta bands, before and after WT, we did not find statistically significant changes in CCs in all the studied electrode pairs. However, in the alpha band, we found a statistically significant decrease in CCs in the frontal region in the F3-F4 (P=0.0038) and C3-C4 electrode pairs (P=0.034). The results of the study of interhemispheric integration showed statistically significant differences between patients with JME and the control group. Conclusion: WT according to the author's method does not provoke the occurrence of interictal epileptiform discharges on the EEG and epileptic seizures in patients with JME. Coherent analysis showed positive changes in interhemispheric integrations of neurons in the beta–1 and alpha frequency ranges, mainly in the anterior hemispheres.
Sleep is one of the most important and vital physiological processes in the human body. In addition to the length of daylight hours, the nature of work activity, bad habits (smoking, alcohol abuse, excessive consumption of caffeine-containing drinks, psychostimulants), the factors that violate the duration and quality of sleep include the nature and style of nutrition, as well as eating habits that affect daily intake vital nutrients (vitamins, essential amino acids, polyunsaturated fatty acids, etc.). Tryptophan is one of the essential amino acids associated with sleep disturbance. Given the high clinical significance of sleep disorders in the development of neurological diseases and mental disorders, the interest of researchers in the study of modifiable and non-modifiable risk factors for sleep disorders is growing. Objective: to analyze and systematize the results of fundamental and clinical studies of recent years on the role of tryptophan in the development of sleep disorders and anxiety-depressive disorders in adults. Materials and methods. This thematic review included available full-text publications obtained as a result of a literary search in the domestic (E-Library) and foreign databases (PubMed, Scopus, Oxford University Press, Springer, Web of Science Core Collection). Results. The role of tryptophan as a key link in the synthesis of melatonin and serotonin in the occurrence of sleep disorders and anxiety-depressive disorders is significant and can be used for further study. Conclusion. Based on the review of the literature, it can be concluded that one of the important mechanisms of sleep disturbance and the occurrence of anxiety and depressive disorders is insufficient intake of tryptophan in the body. This pattern is a consequence of the consumption of food with a low content of this essential amino acid. Considering the consequences that tryptophan depletion can lead to in the human body, competent nutritional support is a necessary measure.
The goal The goal is to study the lateralization of changes in intrahemispheric coherence in accordance with the basic rhythms of electroen- cephalography in healthy young people under the influence of tapping on the wrist in accordance with the author’s technique.Materials and methods: The conduct of this study was approved by the ethics com- mittee of KrasGMU. prof. V. F. Voyno-Yasenetsky (protocol No. 77/2017 of 06/26/2017). The study of the infl of wrist tapping according to the author’s technique on the coefficient of intrahemispheric coherence of the cerebral cortex in healthy volunteers (n2=63). Wrist tapping was carried out using the original technique (RF patent No. 2606489 of 01/10/2017). The analysis of intrahemispheric coherence in the pairs F3–T5, T5–O1, F3–O1, F4–T6, T6–O2, F4–O2 was carried out using a com- puter encephalographic complex (Neurocartograph, MBN Moscow).Results and discussions: According to the studies, it was shown that under the influence of tapping the hand according to the author’s technique, the state of sensory deprivation (closed eyes), statistically signifi changes in hemisphere coherence in theta and beta rhythms were not found, p>0.05, however, we showed a statistically significant (p<0.05) de- crease in hemisphere alpha-rhythm coherence in the right hemisphere in pairs F4–T4 (p=0.0000793) and F4–O2 (p=0.01711824), while the median coherence coeffi before and after tapping changed from 0.27 to 0.315 and from 0.13 to 0.175, respectively. At that time, we did not find statistically significant changes in the coherence of the hemisphere in similar pairs of the left hemisphere p>0.05. As a result of this study, when the wrist tapping was opened with the eyes of the subjects open, statistically significant changes in the coherence of the hemispheric alpha rhythm were detected only in the F3–O1 pair of the left hemisphere (p = 0.0000147), but not in the right hemisphere. At the same time, when the eyes of the volunteers were closed, there were no statistically significant changes in the coherence of the hemisphere in the theta and beta rhythms in both the left and right hemispheres.Conclusion. Thus, the use of tapping the wrist according to the author’s technique with the left hand in right-handed people in a state of sensory deprivation is promising for practical use in neurological practice, in particular in the management of patients with epilepsy and panic attacks, since a patient previously trained by the attending physician — neurorehabilitation, can use this the author’s program on his smartphone, in the case of an epileptic aura of focal epileptic seizures or precursors of panic attacks. However, the clinical application of the author’s technique needs detailed research.
