• Objetive: The main objective of this study was to analyze whether there were differences in dynamic balance and postural stability in relation to the level of disability in patients with chronic low back pain.

  Methodss: This is an observational study in which 60 patients with nonspecific chronic low back pain were included. All patients received a sociodemographic questionnaire, the visual analogue scale (VAS) and a series of self-reported psychological scales. To complete the evaluation, physical tests were performed in which dynamic balance and postural stability were measured.

  Results: Student’s t-test revealed that there were significant differences between the groups in dynamic balance with the right leg and the left leg. In contrast, there were no significant differences between the groups for the reach functional test in forward direction, left direction and right direction.

  Conclusion: In conclusion, our study demonstrates that patients with chronic low back pain with high levels of disability present significantly poorer dynamic balance compared with those with low levels of disability. In contrast, no significant differences were found between the groups in terms of static stability.
