METHOD FOR INFRARED ESTIMATION OF LUMBOSACRAL MUSCLE AND JOINT COMPLEX STABILITY IN FLEXION-EXTENSION MOVEMENTS Russian patent published in 2016 - IPC A61B5/01 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to functional diagnostics, and can be used for infrared estimation of lumbosacral muscle and joint complex stability in flexion-extension movements. Examination is carried out in the plantigrade position, with patient's back turned to the researcher. Measuring instrument is represented by a thermal imager which images an infrared colour object on the screen in the range of temperature of +26-+37 °C. Periodical repeated registration of infrared radiation from the entire area of the lumbar region after is being performed after short-term baring under conditions of room air temperature of +25-+26 °C. Local skin temperature is being recorded by infrared thermography before and after a series of flexion-extension movements, which are being continuously performed for 2 minutes with intensity of 18-22 per minute. After that, time is being noted, and then thermography is being repeated every 1-2 minutes for 10 minutes. In case of detection of local hyperthermia, thermography is being continued every 3-30 minutes up to back temperature recovery. Thermograms are being compared. In the absence of temperature changes, high stability of lumbosacral muscle and joint complex in flexion-extension movements is being determined. In case of detection of one-sided or two-side symmetrical local hyperthermia for up to 15 minutes, satisfactory stability of lumbosacral muscle and joint complex in flexion-extension movements is being determined. In case of prolonged hyperthermia or in case of its asymmetry, double-sided or one-sided low stability of lumbosacral muscle and joint complex in flexion-extension movements and lumbal disease are being determined respectively.

EFFECT: higher efficiency and accuracy of analysis, its simplification and extension of its application in estimation of lumbosacral muscle and joint complex stability to physical activity under conditions excluding its change and providing for verification of a wide range of lumbar diseases.
