The purpose of this study was to investigate between low back pain scale and disability index owing to gait pattern. For the period of February 1 to February 29, 2004, we had conducted a questionnaire and direct interview with 100 persons lived in Daejeon. The result were as follows: 1. The stride length of experimental group. the male was $49.9{pm}12.9cm$. the female $45.7{pm}12.9cm$ and the width of feet, the male was $13.5{pm}5.7cm$, the female $12.2{pm}4.8cm$. 2. The Fick angle of all subjects was showed in external disposition, the left angle showed in asymmetry, the male was $11.0{pm}5.7^{circ}$, the female $8.5{pm}1.3^{circ}$. 3. The foot arch was similar to sex as a weight bearing and non-weight bearing, the male was $1.3{pm}0.8cm$, the female $1.3{pm}0.9cm$. 4. The impedimental index according to back pain grade, men was a lower than women, the male was $5.7{pm}6.9$ and the female $7.2{pm}5.3$. 5. The relation to difference between foot arch and disability index according to back pain grade as a weight bearing and non-weight bearing, the higher foot arch, the higher back pain grade was statistically significance(p<.05). 6. The relation between width of feet and disability index according to back pain grade, the wider width of feet, the higher back pain grade was statistically significance(p<.01). 7. The relation between stride length and disability index according to back pain grade, the wider stride length, the higher back pain grade was statistically significance(p<.05).
