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 discrep-ancy, 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. (J Korean Acad Rehab Med 2006; 30: 392-397)
