Correlation between Flexible Flat Foot and Lumbar Lordotic Angle

Objective: To investigate the effect of flexible flatfoot on lumbar lordotic angle.Material and Methods: This study was conducted at the Faculty of Physical Therapy, Modern University for Technology and Information, Cairo, Egypt, on 40 participants (14 female 26 male) for each subject using lateral weight bearing radiography (X-ray) for foot and lumbar. Assessments were performed to measure the lateral talocalcaneal angle, the talar first metatarsal angle (Meary s angle), calcaneal inclination (calcaneal pitch) angle, the calcaneal first metatarsal and lumbar lordotic angle “LLA”. Measurement of these angles was accomplished by using surgimap spine software (valid and reliable).Results: There was a positive weak significant correlation between lumbar lordotic angle and lateral talocalcaneal (r= 0.421, p=0.007) and between lumbar lordotic angle and talar first metatarsal angle (Meary s angle) (r=0.420, p=0.007). While, there were no significant correlation between lumbar lordotic angle and calcaneal-first metatarsal angle (r=0.265, p=0.098) and lumbar lordotic angle and calcaneal inclination angle (r=0.098, p=0.548.Conclusion: Subjects with flexible flatfoot demonstrated increased lumbar lordotic angle than normal subjects. So, foot assessments are recommended as an essential part of the evaluation of patients with spine problems.
