Abstract

Objectives : The biomechanical relationship of leg length discrepancy(LLD), Lumbar lordosis, pelvic variance and degenerative scoliosis is one of the most important parameters when treat musculoskeletal disorders, however the reports are still controversial. The purpose of this study was to compare the relationships between the parameters and bothersomeness in subject with chronic ow back pain. Methods : Sixty female and eight male adults with non specific low back pain over 3 months were recruited. LLD was measured by tape measure method. Lumbar lordosis, lumbosacral angle and related pelvic parameters were measured using simple radiologic films of lumbosacral view. Results : Lumbar lordosis was significantly correlated to the lumbosacral angle, pelvic incidence and difference of the both iliac widths. Pelvic incidence had significant correlation with difference of the both iliac widths. And difference of both iliac widths was related with LLD by radiologic film. There was also significant correlation between the LLD by radiologic film and tape measurement. Visual analogue scale(chronic low back pain) of normal lordosis group was greater than hyperlordosis group. Conclusions : There were close biomechanical relationships between lumbar, pelvis, and lower extremity. But in order to determine the effect of structure on the chronic low back pain, global balance of musculoskeletal structure seems to be worth further researching.
