Objective. The main task of this study was to find out whether McKenzie concept has a positive or negative outcome on the suppression of pain in patients suffering from acute lower back pain. The desire was ultimately to present specific claims, which could sum up and rationalize the existing thesis and make them applicable to the everyday picture of treatment of these patients. Methods. Tools that have been used in these studies were based on a simple questionnaire called visual analogue scale which is measureing pain from 1 to 10. This method was fullfilled with specific ways of treating pain in the lumbar spine followed by rules end exercises originating from McKenzie therapy concept. In addition to personal measurements, for the credibility of results I studied several different yet similar references and randomized controlled trials that dealt with this type of issue. Results. The measurement results that were given from patients during three week period showed tendency of pain reduction by average 2,5 points on a visual analogue scale of pain. These results were compared and showed correspondency between results of randomized controlled trials that counted up to 150 participants with acute low back pain. Conclusions. According to the results it is concluded that positive outcome of therapy exists. Research has proven interval reduction in pain intensity by average value of 2.5 on the so called ˝VAS˝ scale. This research was supported by several randomized controlled trials that gave more credibitility to obtained results.
