PREDICTIVE MODELS OF THE PROBABILITY OF REDUCING THE LATENCIES OF VISUAL EVOKED POTENTIALS FOR THE FLASH UNDER THE INFLUENCE OF SPELEOTHERAPY

Neurophysiological techniques are used as a means of monitoring the effectiveness of therapeutic interventions, including speleotherapy. A course of speleotherapy improves the speed of the visual signal, the speed of primary processing of information and the speed of analysis of visual information. Purpose. To study the probability of reducing the latencies of visual evoked potential (VEP) waves to a flash under the influence of speleotherapy depending on the initial durations of VEP waves. Materials and methods. 73 2nd year students of VSMU (18-21 years old) took part in our study: 49 students from the experimental group and 24 students from the comparison group. Each participant was informed about the purpose of the study, each signed an agreement to participate in the study. The course of speleotherapy consisted of 10 sessions of 60 minutes each and was carried out in a stationary ground speleochamber at a temperature of 18–22 °C. Before the start of speleotherapy and on the 10th day of speleotherapy at rest, visual evoked potentials to the right and left to the flash were recorded using the neuromyoanalyzer "Neuromian". The analysis of the obtained data was carried out using IBM SPSS Statistics 26. Results. As a result of the study, three clusters of subjects were identified, which differ in the dynamics of the latency of the wEP waves under the influence of the speleoclimate. It has been established that this dynamics depends on the initial parameters of the wEP waves. The performed discriminant analysis made it possible to obtain three prognostic models for the probability of a decrease in the latency of the N2, P1, P2 of wEP waves to a flash on the left under the influence of speleotherapy, depending on the initial durations of the wEP waves. The sensitivity of the models is from 84,6-92,9%, the specificity is 93,8-95%. Conclusion. The obtained data can be used for personalized selection of an algorithm for preventive measures using speleotherapy.
