Objective : To purpose of this study was the most of the ladies wear high-heeled shoes at lease 4 to 5 day a week but the effect of it's height on the lumbo-sacral legion angle has not been clearly defined. Method : Subject were 20 young ladies, who had majored in physical therapy of the Dae-gu Health College. Method 1. PACS system X-ray was used to measure the lumbo-sacral legion angle under the condition of bare foot, 3cm, 7cm high-heeled at standing position. 2. Spinal Mouse was used to measure the spinal segment motion angle and length under the condition of bare foot, 3cm, 7cm high-heeled at being Flexion-Extension position Result : The result of this study were as follow I. Significant statistical increase in lumbar lordosis was observed as the heel height was increased from bare foot to 7cm high-heeled(p<.05), but there was no significant difference in the lumbo-sacral angle & sacral angle(p>.05). 2. The Height and the weight of the subjects, their preference on the shoes didn't affect the lumbo-sacral lesion angle(p>.05) 3. The variation of the heel height didn't affect the spinal segment motion angle and length(p>.05). Conclusion : There is strong relationship between the high of heel with increasing the lumbar lordosis(p<.05).

Objectives : The aim of this study was to evaluate whether the foot pressure distribution correlates with the lumbo-sacral curvature, and the Oswestry Disability Index in chronic low back pain patients. Methods : We measured the fore foot pressure and the rare foot pressure using the foot analyzer in 28 women subjects with chronic low back pain. The lumbo-sacral curvature and the Oswestry Disability Index(ODI) were also measured. Results : 1. Subjects with higher ODI(%) had significantly lower Fore foot pressure/Rare foot pressure ratio(F/R ratio) (p<0.01). 2. Lumbar lordotic angle and Ferguson angle were inversely related to ODI(%) (p<0.05, p<0.01). 3. Lumbar lordotic angle and Ferguson angle were positively related to F/R ratio (all p<0.05). Conclusions : Using the Foot Analyzer(FA-48S, Tech storm Inc.) we have shown that F/R ratio has significant correlation with the lumbo-sacral curvature and the Oswestry Disability Index. These result suggest that the Foot analyzer may be used in assessing back pain in chronic low back pain patients.

The purpose of this study is to investigate the effect of low back pain(LBP) and pelvic displacement on foot orthosis. Before and after experiments were designed to compare the effect. 21 LBP patients who were the subjects diagnosed of applying foot orthosis for 3 weeks after, investigated about pelvic obliquity angle, displacement of ilium, lumbo-sacral angle by x-ray test which is one of pelvic displacement tests, visual analogue scale is used for LBP measurement. The result show the followings; First, Pelvic obliquity angle was significantly reduced after applying foot orthosis compared before using it(p<.05). Second, Displacement of ilium was significantly reduced after applying foot orthosis compared before using it(p<.05). Third, Lumbo-sacral angle was significantly reduced after applying foot orthosis compared before using it(p<.05). Fourth, LBP was significantly reduced after applying foot orthosis compared before using it(p<.05). This study tries to suggest new LBP treatment to reduce pelvic displacement by apply foot orthosis. In conclusion, foot orthosis reduces pelvic obliquity angle, displacement of ilium, lumbo-sacral angle and also decrease LBP. Further more, It needs of biomechanical study which can recognize relation between foot arch and pelvic displacement. This study will serve as a clinically useful data for diagnosis and treatment of LBP and biomechanical analysis of lower limb.
