Background:Despite the fact that the introduction of biological disease-modifying antirheumatic medicines (bDMARDs) and the early start of treatment for rheumatoid arthritis (RA) can effectively stop the inflammatory process in RA, a fairly large number of patients continue to experience joint pain [1]. It is assumed that in some cases, joint pain in patients with RA is not associated with the inflammation, so it requires consideration of the possibility of using alternative strategies for the treatment of RA.Objectives:The aim of the research is to study the effectiveness of laser therapy in the treatment of RA.Methods:114 patients with RA aged from 32 to 53 years have been monitored for 6 months. There were 82 women (71.9 %) and 32 men (28.1%) among them. The patients were randomly divided into 2 groups. The first group of patients (57 people) received basic medical therapy with methotrexate 15 mg intramuscularly once a week and nonsteroidal anti-inflammatory medicines (NSAIDs) on demand. The dose of methotrexate was selected taking into account the disease activity index DAS 28. The second group of patients (57 people) received basic medical therapy with methotrexate 15 mg intramuscularly once a week and NSAIDs on demand. In addition, the cutaneous low-intensity laser irradiation of the joints was added along the projection of the joint gap in a pulse mode with a wavelength of 0.89 microns. The pulse frequency is 80-1500 Hz, the pulse power is 5 W, the exposure time in the field is 1-2 minutes and the total radiation time per session is no more than 10 minutes [2]. The course of treatment consisted of 10 procedures (the device “Milta F-8 RD”, Russia, Moscow). The course of laser therapy was repeated after 4 weeks. To assess clinical indicators, patients were examined using the SF-36 questionnaire before treatment and 6 months after the start of treatment.Results:The survey after 6 months revealed the significant decrease in the severity of pain on the VAS from the initial average indicator 4.5±0.2 to 3.69±0.2 points (p<0.01) and morning stiffness from 60±5 to 40.8±4 minutes (p<0.01). In the first group, the dynamics of clinical indicators were not statistically significant: the intensity of pain decreased from 4.6±0.2 to 4.2±0.3 points (p>0.05) and the duration of morning stiffness reduced from 62±7 to 58.6±6 minutes (p>0.05). In the second group the decrease in the need for NSAIDs was observed in 21 patients, while in the first group the same was observed only in 10 patients (px2 = 0.020).Conclusion:Laser therapy in the treatment of patients with RA enabled to decrease the frequency of the need for NSAIDs and reduce morning stiffness. We recommend using laser therapy in patients with RA at the second radiological stage as an addition to basic therapy.References:[1]Altawil R et al.
