Objectives The present study retrospectively investigated clinical outcome of patients with structual scoliosis during Chuna treatment. Methods : The study population consisted of 34 patients(14 patients of adolescent and 20 patients of adult) who were diagnosised as scoliosis with radiological finding. All patients were treated with Chuna treatment, and after treatment, evaluated with radiological measurement by calculating the scoliosis correction angle from the Initial and follow-up spine AP and lateral views. Also the evaluation of clinical outcome was done twice pre and post treatment during this study. Results : The results were summarized as follows ; 1) The 85.3 percent of patients complained physical pain. and adult group had various painful lesion compared with adolescent group. 2) Adult group had treated $18.0{pm}7.2$ times and adolescent group treated $13.5{pm}5.7$ times with Chuna treatment. 3) Scoliotic angle is reduced in 92.9 percent of adolescent group and had all of adult group after Chuna treatment, especially, statistically significance appeared in adult group. 4) Adult group was superior to adolescent group in correctability and scoliotic angle change. 5) Correction effect was better in the group which initial scoliotic angle was lessor, or had more time of treatment. 6) According to grade of vertebral body rotation, scoliotic angle is larger and correctability was lower. Conclusions : Chuna treatment was efficacious against scoliosis. And it is necessary for adolescent scoliosis patient to be more carefully treated and observed.
