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.
