Abstract	Introduction: Sustained Natural Apophyseal Glide has been suggested as a technique with potential benefits in reducing pain and increasing the range of lumbar flexion in patients with low back pain. However, there is no evidence on this technique in muscle activity of the erector spinae. Objective: To evaluate the immediate effects of a Sustained Natural Apophyseal Glide in muscle activity of the erector spinae, the intensity of pain and the real range of lumbar flexion in subjects with chronic non-specific low back pain. Methods: An experimental study with a sample of 20 university students with chronic non-specific low back pain and pain on flexion of the lumbar spine, which were randomly allocated to two groups: experimental Sustained Natural Apophyseal Glide and placebo – placebo intervention. Were evaluated the activity of the erector spinae muscle using the surface electromyography (bioPLUX research ® ), pain intensity using a visual analogic scale and the real range of lumbar flexion with a double inclinometer method (Universal Inclinometer ® ) before and after the intervention, by the analysis of the flexion-extension movement of the upper-body. The significance level was 0,05. Results: Significant differences were found in both groups for the relaxation phase (Experimental Group: p=0,013 and Placebo Group: p=0,047), as well as for the extension phase, in group experimental (p=0.037), verifying a decrease in muscle activity from baseline to final evaluation. The realization of Analysis of Covariance revealed, with regard to pain intensity, there were significant differences between the two groups (p=0,002), and the experimental group decreased more 2cm in Visual Analogic Scale than placebo group. Analyzing the real range of lumbar flexion, although the increase was not significantly different between groups (p=0.086), experimental group increased 1,7° more than placebo group. Conclusion: The results suggest that, in the short term, the Sustained Natural Apophyseal Glide seems to have a significant effect on the decrease of activity of the erector spinae muscles during dynamic movement of the upper body extension, as well as pain relief. Although there were no significant changes observed in increasing range of motion, results in the experimental group were higher than the minimal detectable change, suggesting a positive effect of the applied technique.
