title: The Māori foot exhibits differences in plantar loading and midfoot morphology to the Caucasian foot.
abstract: The question being addressed in the current study was whether the diabetic Māori foot was more or less prone to ulceration than the diabetic New Zealand Caucasian (NZC) foot. Harris mat and pedobarographic analyses were employed to assess static and dynamic foot morphology and plantar loading in 40 Māori and NZC diabetic and non-diabetic participants. Significantly higher peak pressures were exhibited by the diabetic Māori participants compared to their NZC peers at the central forefoot. Significantly higher static and dynamic arch index values and significantly higher sub-arch angle values were exhibited by the non-diabetic Māori participants compared to their NZC peers. The latter findings suggest that healthy Māori may have a predisposition towards having a flatter foot than healthy NZC, which may have footwear design implications.
