O3406 ANTHROPOMETRIC STUDY ON SHOE-WEARING AND NON-SHOE WEARING POPULATIONS

Abstract

Aims: To assess the difference in muscle function and pliability between shoe wearing and non shoe-wearing feet. Methods: Using a basic force gauge, force of extension and ßexion at 1st metatarsophalyngeal joint, abduction at 5th metatarsophalyngeal joint and adduction between 1st and 2nd toe was measured on the right foot of 100 (50 male and 50 female) randomly selected human population. They had normal body-mass index and age between 25 to 35 years. People with previous injury or disability to the right lower extremity were excluded. Measurement on non-shoe wearing population was carried out on Indian population. Measurements on shoe-wearing population were carried out on the British population. Maximum length and breadth of full weight bearing and non-weight bearing foot was measured. Pliability Ratio of weight bearing length and breadth of the foot by the non-weight bearing length and breadth of the foot was calculated. Results: There was no statistically different muscle force in the small joints of the feet. Pliability ratio showed that the shoe wearing feet were stiffer than non-shoe shoe wearing feet. Conclusions: Shoe wearing does not affect the intrinsic foot function. It may result in slightly stiffer feet. This can result in improper distribution of force while weight bearing Pediatric hip
