1 Received : Reviewed : Accepted : A Study on Correlation between Power of Trunk Flexors, Extensors and Lumbar Lordotic Angle in Normal Adults Bo-Mi Choi, K.M.D. Jeong-Min Yi, K.M.D. Hyun-Soo Kim, K.M.D. Dept. of Korean Rehabilitation Medicine, College of Oriental Medicine, Dae-Jeon University Objectives : The purpose of this study was to investigate the correlation between lumbar lordotic angle and the power of trunk flexors, extensors in normal adults Methods : 34 normal participants participated in this study. Their lumbar lordotic angle(l1-s1 Cobb s angle and L1-L5 cobb s angle) was measured by x-ray taken on lateral direction, erect cross-arm position. And muscle power of trunk flexors and extensors of each participant measured using Cybex HUMAC NORM. Results : 1. The average of L1-S1 Cobb's angle was and the average of L1-L5 Cobb s angle was (Table ). 2. The average ratio of trunk flexors/extensors was %(Table ). The average power of the trunk flexors was (Newton-Meter/kg), and the power of trunk extensors was (Newton-Meter/kg)(Table ). 3. Lumbar lordotic angle has no relation to the ratio of trunk flexors/extensors(table, Fig. 4). 4. Lumbar lordotic angle has no relation to both the power of the trunk flexors and extensors(table, Fig. 5, Fig. 6). Conclusions : These results suggest that the lumbar lordotic angle measured by radiograph could not evaluate the power and ratio of trunk flexors, extensors. Keywords : Lumbar lordotic angle, Trunk flexors, Trunk extensors 39
