LASER THERAPY IN MEDICAL REHABILITATION OF THE PATIENTS AFTER KNEE REPLACEMENT
In the modern scientific literature there is evidence that microcirculatory disorders are observed in many diseases and are a link in the pathogenesis of many diseases. Therefore, the study of the functioning of the microvasculature makes it possible to more adequately select and evaluate the effectiveness of physiotherapeutic methods of the treatment. The purpose of the study is to determine the informative value of Laser doppler flowmetry method in assessing the effectiveness of the treatment of patients after total knee replacement (TKR) using pulsed and continuous infrared low-energy laser radiation (IR LELR). Material and methods. There have been examined 40 patients after knee replacement at the age of 50 to 75 years old. All the patients were divided into two groups comparable in clinical and functional characteristics. In the first group (20 people) IR LELR exposure was carried out in a continuous mode. In the second group (20 people) IR LELR exposure was carried out in a pulsed mode. The state of microvasculature in the affected limb was assessed using laser Doppler flowmetry (LDF). Results. According to LDF, microcirculation disorders were detected with all the patients after the knee replacement. In 92% of the patients, hyperemic type of microcirculation (group A) was detected and 8% of the patients had normocirculatory type of microcirculation (group B). More significant dynamics was noted in the group of patients with hyperemic type of microcirculation who received IR LELR in a pulse mode. Conclusion. Thus, based on the conducted studies, it can be stated that after the knee replacement, the use of IR LELR in a pulsed mode has a more pronounced effect on the state of microcirculation compared to IR LELR in a continuous mode.
