“…This method implies finger tapping on screen of a device (Android-based smartphone) ( Figure 1) for 1 minute with frequency comfortable for a subject. Software was able to register temporal parameters of this process (number of taps per minute), pressing intensity and steadiness throughout the whole cycle [18]. Software automatically calculated average, maximal and minimal frequency (in Hz); average, maximal and minimal interval between taps (in seconds); pressing intensity and percentage of rhythm steadiness.…”

Aim -To study the influence of anxiety on parameters of wrist tapping in normal conditions and in juvenile myoclonic epilepsy (JME). Material and Methods -We evaluated 105 people aged 16 to 55 years old (average: 31.6±10.2 years). The sample was comprised of two groups: first (I) group -healthy volunteers (n=60); second (II) group -patients with JME (n=45). Every group was stratified into two subgroups: subgroup Ia (n=33) -healthy volunteers without symptoms of anxiety; subgroup Ib (n=27) -healthy volunteers with subclinical anxiety; subgroup IIa (n=19) -patients with JME without symptoms of anxiety; subgroup IIb (n=26) -patients with JME with subclinical anxiety. Wrist tapping parameters were studied using method of our authorship named «Method of influencing a person's individual rhythm through exogenous rhythmic stimulation». We studied reference ranges of basic characteristics of wrist tapping. Results -Comparison of basic parameters of wrist tapping in subgroups Ia and IIa revealed a trend towards an increase in rhythm stability in patients with JME when compared to healthy volunteers. At the same time, subclinical anxiety led to a pronounced increase in frequency of individual rhythm in subgroup IIb when compared to subgroup Ia. Conclusion -Influence of anxiety on wrist tapping parameters is more pronounced in patients with JME when compared to healthy volunteers.

The goal is to study the dynamics of the inter-hemispheric coherence coefficient of the cortex according to the main rhythms of the electroencephalogram before and after the BOS-therapy based on the wrist tapping on the author’s method and the effect of subclinical anxiety on the characteristics of wrist tapping in healthy adults.Materials and methods. The conduct of this study was approved by the ethical committee of KrasSMU. prof. V. F. Voyno-Yasenetsky (protocol No. 77/2017 dated June 26, 2017).The study was conducted in two stages. The first stage is the study of standards and the influence of wrist tapping according to the author’s method on the characteristic of the “internal” rhythm in healthy adults without anxiety and with subclinical anxiety (n1 = 60). The second stage is the study of the influence of wrist tapping according to the author’s method on the coefficient of hemispheric coherence in the frontal areas of the cerebral cortex in healthy volunteers (n2 = 63). Study of wrist tapping was carried out using the original technique (RF patent № 2606489 from 10.01.2017). Anxiety level testing was performed using a scale (HADS hospital anxiety and depression scale [1]). Analysis of interhemispheric coherence in Fp1 — Fp2, F3 — F4, T3 — T4 pairs was performed using a computer encephalographic complex (Neurokartograf, MBN Moscow).Results and discussions. The main characteristics of the “internal” rhythm according in healthy adults are statistically significant depending on the absence or presence of subclinical anxiety (1.13 Hz vs. 1.53 Hz, respectively). According to the author’s method, wrist tapping statistically significantly reduces the coefficient of interhemispheric coherence in Fp1-Fp2, F3-F4, C 3-C 4 pairs located above the convexital surface of the frontal cortex, which can be used as a method of non-pharmacological correction of anxiety disorders in the future.Conclusion. Subclinical anxiety affects the indicators of the “internal rhythm”, which is studied using wrist taping according to the author’s method. Wrist tapping in healthy adults leads to a decrease in the interhemispheric integration of frontal cortex neurons and interhemispheric coherence coefficients in beta1- (predominantly) and alpha rhythms, without affecting the coefficients of coherence in theta rhythm. Wrist tapping according to the author’s method is a promising option for BOS-therapy in adults to reduce the level of anxiety in normal and pathological conditions.

“…Exposure to external stimuli can provoke epileptic seizures and, conversely, if the selected frequencies come into resonance with the neurons of the antiepileptic system, an antiepileptic effect can be obtained. The theory of resonance, nowadays, is increasingly used in neurorehabilitation, when the impact of external stimuli with a certain frequency, which is in resonance with the neuronal activity of protective systems, can have a clinically significant therapeutic effect [8,9]. Thus, using the theory of resonance and hypersynchronization, we can, by external influence at certain frequencies, desynchronize neurons (neural network) in the focus of epileptic activity, achieve the phenomenon of resonance with neurons of the antiepileptic system and reduce the risk of developing generalized and secondary generalized seizures.…”

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.
