Relationship between the changes of pelvic obliquity (ΔPOb) and lumbar scoliosis (ΔLS). Positive correlation was observed betweenΔPOb andΔLS (correlation coefficient = 0.59). Horizontal axis means degree of the change of POb. Over 3.5 degrees was defined as significant (ΔPOb(+)). Vertical axis means degree of the change of LS. Over 5 degrees was defined as significant. ΔLS(-) means scoliosis was improved, ΔLS(n) means scoliosis did not changed, andΔLS(+) means scoliosis got worse.
