    Abstract

    Background: Indians are the largest single ethnic minority group in the United Kingdom and form more than one million of the current population. No studies have investigated foot pressure differences between Caucasians and Indians. Objective: The aim of our study was to investigate the in-shoe pressure differences in Caucasians and Indians using the Pedar-m (Novel GmbH, Germany). Methods: The study included 12 Caucasians and 21 Indians. Peak pressure (PP), contact area (CA), contact time (CT), pressure-time integral (PTI), force-time integral (FTI), instant of peak pressure (IPP), maximum force (MaxF) and mean force (MeanF) were recorded. Results: Caucasians had higher significant PP compared to Indians under the heel (293. kPa vs. 251. kPa; P<0.001), 1st metatarsal head (294. kPa vs. 233. kPa; P= 0.01), 2nd metatarsal head (266. kPa vs. 236. kPa; P= 0.03), 3rd metatarsal head (254. kPa vs. 223. kPa; P= 0.04), and the 5th metatarsal head (168. kPa vs. 133. kPa; P= 0.04). There was no significant difference in the contact area between the two race groups. The PTI was statistically significantly higher in Caucasians in the region of the 1st metatarsal head (79. kPa. s vs. 62. kPa. s; P= 0.03) and 5th metatarsal head (58. kPa. s vs. 44. kPa. s; P= 0.03). There were no significant differences among CT, FTI, IPP, MaxF and MeanF among them. Conclusion: The PP under the heel, 1st, 2nd, 3rd and 5th metatarsal heads and the PTI under the 1st and 5th metatarsal heads in Caucasians is higher than in Indians. There is no difference in the CA.
