Background: changes of planter pressure distribution and alteration of foot mechanics in adolescents with idiopathic scoliosis have been investigated in many studies. Altered foot pressure in unbalanced anatomical position accumulates stresses to the musculoskeletal system and causes vertebral deformation. Yet, little is known about the effects of customized insoles in idiopathic scoliosis. Purpose: The purpose of the study was to evaluate the effectiveness of customized planter pressure redistribution insoles on the spinal and pelvic parameters as well as on functional disability in patients with adolescent idiopathic scoliosis (AIS). Methods: thirty patients with AIS (19 females, 11 males) with mean age of 16.5 {uF0B1} 1.97 years, body mass of 65.93 {uF0B1} 5.72 kg and height of 1.66 {uF0B1} 0.06 m participated in this study. The measured parameters were radiographic Cobb{u2019}s angle and rasterstreographic scoliotic angle, kyphotic angle, lordotic angle, pelvic obliquity, pelvic torsion, and vertebral rotation in addition to functional disability as measured by Oswestry disability index. Data collected before and after three weeks of wearing the customized insoles were compared for statistical difference. Findings:One way within subjects MANOVA and Wilcoxon Signed Rank tests revealed that all measured spinal and pelvic parameters decreased significantly (p<0.05) after the use of the customized plantar pressure redistribution insoles. Moreover, there were significant reductions of the pre-experimental Oswestry disability index scores. Moderate positive correlations were found between X-ray Cobb{u2019}s angles and scoliotic angles as measured by DIERS Formatric 4D. Interpretation: customized planter pressure redistribution insoles are effective in improving trunk, pelvis alignment and functional disabilities in patients with AIS. DIERS Formatric 4D is useful method for assessment of Scoliosis
