Analysis of asymmetric pelvic shift in the overhead squat assessment of patients with chronic low back pain

This study on asymmetric pelvic shift identified in over-head squat recruited 48 adults with chronic low back pain. The malalignment of lumbopelvic was assessed by AP stand X-ray and the results showed that 75%(n=36) of participants have pelvic level difference and lumbar scoliosis. The participants were, based on the results of X-ray assessment, classified into three groups: A group (neither pelvic level difference nor lumbar scoliosis; n=12), B group (only pelvic level difference; n=17), and C group (only lumbar scoliosis; n=19) and were assessed on asymmetric pelvic shift during over-head squat. The asymmetric pelvic shift was shown to have significant association with malalignment of lumbopelvic(P<0.001) and highest in C group. The differences in malalignment of Lumbopelvic among groups were also significant, suggesting that the lumbar scoliosis has more effects on asymmetric pelvic shift during squat.
