Abstract
Background
Low back pain (LBP) is a widespread, expensive, and debilitating problem.1 Though LBP can be caused by acute injuries, biomechanical discrepancies have also been indicated. Approximately 80% of the general population has alterations in the feet; these kinematic changes affect the lower extremity kinetic chain and may lead to pathologies of the lower back later in life. The true prevalence of flatfoot is unknown, primarily because there is no consensus on the strict clinical or radiographic criteria for defining a flatfoot.
Objective
To identify the occurrence of flat feet in chronic low back subjects, determine the factors associated with occurrence of flat feet and to state the relationship between flat feet and chronic low back pain.
Methodology
Study proceeded after ethical clearance from the institutional ethical committee of Nitte University was granted. 71subjects satisfying the inclusion criteria from the period between April 2016 to februray 2017 were included. Assessment of all patients included study specific designed tool, NDT, FPI, VAS and Oswestry Low Back Pain Disability Questionnaire.
Results
The occurrence of flat feet according to the designed tool was 45.07 % in the right foot and 49.29% in the left foot. Severity of pain was not related to the plantar arch.
Conclusion
Presence of flat foot is a common phenomenon among the population with chronic LBP and hence, there exists a need for treatment of LBP to be directed towards the biomechanical corrections of the lower extremity kinetic chain. Future scope of Studies involving assessment of dynamic foot function as well as radiographs of lower extremity and larger sample size can be conducted.
