Abstract: Objectives: the purpose of this prospective study among healthy
athletes was to verify the possible effects of lumbar manipulation on symmetry,
analysing the measured outcomes from physical tests. Methods: Young athletes
of both genders were selected according to the eligibility criteria, randomly
allocated into experimental and control groups. Data were collected with two

force platforms integrated with motion capture system, to retrieve the bilateral
ground reaction forces, to apply the symmetry index. All participants performed
three commonly used physical performance tests, including static posture, squat,
and vertical jump, before and after the lumbar manipulation and control
intervention. Results: In the group 1 pre- to post-lumbar manipulation, statistically
significant differences were found in bilateral symmetry. The improvement
of symmetry was found in static post-lumbar spinal manipulation. In the group 2
pre- to post-control intervention, no statistically significant differences were
found. Conclusions: The athletes from group 1, benefited regarding to the static
symmetry after lumbar intervention. These findings suggest that one single
lumbar spinal manipulation, actually took place, producing effects on symmetry.
