Abstract
Introduction. In otorhinolaryngology, as well as in other fi elds of clinical medicine, often the question of sedative therapy arises. Sedative medication use is not appropriate always and it can cause side effects or can be incompatible with other medicines. The question of sedative therapy arises in psychosomatic conditions, caused by tinnitus, labyrinthopaties, that may have diverse origins, but are accompanied, in any case, by acoustic or vestibular stress. Rhythmical, pulsating light and/or sound stimulators are able to make some changes in person’s behavior, her mood, her working ability, stimulate its activities or lead to a calm state, relaxation.In 30th German doctor Hans Berger has found, that using visual stimulators of a certain frequency can cause certain «electroencephalogram samples» and with changing the frequency of the stimulator the frequency of bioenergy under cord can change.In 90th in Germany there was the so-called «Mind machines» («brain machines») created, which were able to increase intellectual activity «remove» fatigue, build resistance to stress and others with eye irritation by fl ashing light with appropriate frequency.Now we know that rhythmical visual stimulation (VS) and, even more, audio-visual stimulation (AVS) can cause positive and lasting physiological effects from the state of relaxation to the state of activation and increased attentiveness. Authors consider that the Schumann’s frequency «quasi – frequencies of good weather» are causing the mental state of life satisfaction, peace.
Material and methods. The device, that this department staff developed is different, as well as it’s generated with the proposed, using opto-electronic, system and its light stimulator is programmed on to the eye area with the fl exible fi ber body. FS starts with stimulation frequencies in the α- rhythm ( 10 Hz ) and for 10 minutes the frequency is reduced to 4 Hz (τ- wave), and for the next 5 minutes. – to 2 Hz (δ- waves). After this the frequency rises again to 7 Hz for 5 minutes and for 1 min. increases to 10 Hz and up to 99 Hz. The device was used as a supplementary treatment for chronic tinnitus and was seen as a method of psychosomatic stabilization.
Results. During the experimental application of the method in the treatment of 20 patients with chronic subjective tinnitus turned out that the effectiveness of sedation byphoto triggering was positive (subjective noise reduction, improving performance audiometric) in 56.2% of patients. However, the negative impact on the patient’s condition is not found in any case. Discussions. Preliminary studies indicate that the effect of sedation during stressful situations that can occur in any area of medicine, including otorhinolaryngology, can be achieved without the use of drugs such as way of brain waves photo triggering. The method was particularly effective in treating of tinnitus. This allows us to continue research in a wider range. Perspective. It is hoped that the application of the photo triggering technique is promising as well as the treatment of post-traumatic stress syndrome, in sports medicine and other areas of medicine.
Conclusions. The intermittent light stimulators, that have the frequency equal to the brain biorhythms frequency, are capable to trigger mentioned biorhythms and cause a corresponding emotional state. By brain biorhythms triggering the relaxing state can be achieved without using of drugs.The proposed device has several advantages over existing devices. The effectiveness of the procedure may be estimated by using the biofeedback – controls provided in the presented model.The application of the photo triggering technique may be used in the treatment of post-traumatic stress syndrome, in sports medicine and other areas of medicine.
