Optimal frequency characteristics of impulse laser in treatment of patients with atherosclerosis of blood vessels in lower extremities

The research goal is to assess on a comparative basis the effects of the infrared low-intensity laser emission with the frequency of 80 Hz and 1500 Hz on the state of microcirculation and peripheral blood circulation among 30 patients with atherosclerosis of the vessels of the lower extremities. Material and Methods. The patients were divided into 2 groups: in the 1st group (15 patients) patients received pulse infrared low-intensity laser radiation with the frequency of 80 Hz; in the 2nd group (15 patients) infrared low-intensity laser radiation with the frequency of 1500 Hz was used. Results. As a result of the conducted investigation, it was found that optimum pulse repetition rate was 80 Hz because more significant changes in the system of microcirculation and peripheral blood circulation among patients with atherosclerosis of the vessels of lower extremities were revealed. Conclusion. The optimal frequency pulse is determined to be 80 Hz.
