Abstract

OBJECTIVE
To investigate the effect of foot orthosis on spinal curvature, by correction of foot pronation and limb length discrepancy METHOD: 38 cases of foot-pronated children were investigated for changes in Cobb's angle before and after applying foot orthosis, and followed up after 6 months.
RESULTS
There were 25 males and 13 females, and the average age was 10.28+/-0.45 years. There were no significant correlation among Cobb's angle, limb length discrepancy, and difference of pronation. Cobb's angles were improved in 26 cases after applying foot orthosis, by mean 5.84+/-2.47 degree. 16 cases were followed up after 6 months, and Cobb's angle were maintained or improved in 11 cases. Mean correctability was 47.93+/-26.47%.
CONCLUSION
This study showed that foot orthosis could be one of the effective method to improve spinal curvature.
