Abstract
Background and Aim: The aim of this study was to evaluate the sensitivity of the ratio method in extracting FRP in two healthy groups with chronic non-specific low back pain.
Materials and Method: 10 patients with non-specific chronic low back pain and 10 healthy individuals were volunteers participating in this study. Each participant performed a forward bending motion with a straight knee. Each forward bending motion consisted of four steps (Step 1) standing in the starting position. 2) Trunk flexion at a constant speed (using a metronome) 3) In full bending mode (4) trunk extension to standing position), each of which did this for 5 seconds and 3 times.
Results: The results showed that the sensitivity of all modes of the Ratio method except the third mode (60%) in the diagnosis of FRP in healthy individuals was 100%, but in the low back pain group, the sensitivity of the first mode is 70%, the second mode 80%, the third mode 40% The fourth mode was 50%, the fifth mode was 40% and the sixth mode was 50%.
Conclusion: Ratio methods (except for the second case) to extract the FRP are valid in healthy people, but when using this method for people with low back pain, this method should be used with caution and in fact the second mode to extract the phenomenon Relaxation flexion is valid in people with low back pain.
Keywords: flexion-Relaxation, Low back pain, Erector spine
