THE CORRELATION BETWEEN MECHANICAL LOW BACK PAIN AND FOOT OVERPRONATION IN PATIENTS REFERRED TO HAZRAT RASOOL HOSPITAL

Abstract

Introduction: Based on Janda’s theory of kinetic chain, dysfunction in one motor segment can affect other segments in the body. The purpose of the study was to determine the correlation between low back pain (LBP) and foot overpronation in patients presenting to Hazrat Rasool Hospital. Materials and Methods: In this case control study, 242 subjects were classified into two groups of LBP and healthy. The duration and intensity of LBP, flexibility of trunk, foot overpronation (by Helbing sign and Navicular Drop test) and ankle dorsiflexion range were evaluated. The independent sample t-test and Chi-square test were used for statistical analysis of the data. Results: A significant correlation between was observed between foot overpronation and LBP (p=0.001). There were significant relationships between LBP intensity and foot overpronation (p=0.001), between the history of LBP and foot overpronation (p=0.001) and also between foot overpronation and ankle dorsiflexion range (p=0.014). Conclusion: The findings of this study indicate significant relationships between the incidence, intensity and duration of LBP in patients with foot overpronation. Furthermore, ankle dorsiflexion range was reduced in the subjects with foot overpronation.
