Mechanisms of low-temperature rehabilitation technologies. Sports traumatic brain injury

Abstract

According to various data, sports traumatic brain injury (TBI) accounts for up to 20% of all injuries in athletes, and the number of cases of traumatization is progressively increasing year by year due to an increase in the number of people involved in sports, the growing popularity of extreme and contact sports, as well as a high level of motivation to achieve record results. The structure of sports TBI is dominated by mild TBI, which can provoke the development of a very wide range of complications and negative consequences that affect not only the result, but, most importantly, the quality of life of athletes. The pathogenesis of mild TBI has been studied, therapy and rehabilitation programs have been developed. At the same time, the features of sports TBI that significantly distinguish it from domestic, road or criminal injuries are not sufficiently taken into account: repeated frequent TBI, increased body and brain temperature, peripheral redistribution of blood flow and hypocapnia associated with physical exertion and significantly affecting cerebral blood flow. An athlete receives a TBI during the most vulnerable period for the brain. To a large extent, these features are associated with the high incidence of various kinds of neurological complications of sports TBI (cognitive disorders, memory impairment, sleep disorders, migraines, etc.). Special techniques that can prevent complications of sports TBI have not been developed. Brain injury is an independent cause of the development of cerebral hyperthermia, which significantly worsens the course and consequences of TBI. The well-known technology of craniocerebral hypothermia (CCG) allows to reduce physical general and cerebral hyperthermia, to increase the resistance of neurons of the cerebral cortex to hypoxia and trauma. However, this technology is used sporadically, which, apparently, is due to the lack of awareness of coaches and doctors of sports teams specializing in sports medicine and rehabilitation. The purpose of the review is to analyze the features of the action of selective hypothermia of the cerebral cortex, used to prevent complications of mild sports TBI.
