Abstract

Introduction: The literature showed controversies about the stabilization provided by the anticipatory activation of the deep trunk muscles and the evidence based on the bilateral analysis of the muscle reaction time (onset) of subjects with low back pain is poor. Objectives: to compare the trunk muscle onset between healthy subjects and people with recurrent low back pain, as well as to compare the muscle onset between the trunk sides in these populations. Methods: 19 subjects with low back pain and 19 healthy subjects performed the arm elevation test of the dominant upper limb, in which the electromyographic signals of the trunk muscles were collected. Results: in the groups comparison, subjects with low back pain had faster responses of the contralateral internal oblique to the raised limb (p = 0,016). In the comparison between the sides, healthy subjects presented significant difference between the onset of the internal oblique (p = 0,043). Conclusion: recurrent low back pain causes alteration of the motor responses generated by the postural destabilization.
