[Determining the risk of maladaptation using an electroencephalogram to prevent mental strain].

Objective: To identify criteria for electroencephalogram (EEG) synchronization in patients with post-traumatic stress disorder (PTSD) exhibiting high levels of functional stress and signs of maladaptation.

Material And Methods: Two groups of male subjects aged 23-38 years were examined: a group of subjects receiving therapy for PTSD at a medical center; and a group of healthy subjects who regularly practiced psychophysical relaxation sessions. EEG, an innovative method for analyzing brain synchronizing currents, and the Spielberger State-Trait Anxiety Inventory were used.

[Efficiency of acupuncture and relaxation sessions in improvement of psychophysical state].

A study of the changes in psychophysical function of the human body before and after relaxation sessions and acupuncture application has been conducted. The impact of relaxation sessions on psychophysical performance was studied on a group of university students and postgraduates aged between 18 and 30 years old; the impact of an acupuncture session course - on a group of subjects of a broad age range between 14 and 72, as they underwent rehabilitation therapy for their supportive locomotive apparatus disorders. The recording techniques used included electroencephalography (EEG), psychomotor reaction recording, minute-long time span accuracy reproduction; TST technique (Tactile Solar Test) of meridian and microsystem examination The results of this study suggest that relaxation sessions contribute to the enhancement of neurodynamical performance and mental activity efficiency.

[Endurance and Fatigue Caused by Local Muscular Performance in Skilled Athletes].

It was the objective of this research to study the functional parameters of endurance and performance and the brain electrobiological activity during local antebrachial muscle work performance among skilled athletes and unfit people aged 18-23. We examined performance and the brain bioelectrical activity changes at local muscle work by means of an ergograph until fatigue. Our results suggested that local performance increased the spectral power of slow alpha- and theta waves as the fatigue set in, but these changes developed slower and were manifested later in the athletes than in the unfit people.
