Pedobarography is commonly employed in patients with diabetic peripheral
neuropathy (DPN). However there is no evidence regarding test-retest reliability
of this technique in this population, and therefore it was the purpose of the
current study to address this clear gap. Dynamic plantar loading and foot
geometry data were collected during barefoot gait with the EMED platform (Novel
GmbH, Germany) from 10 patients with DPN over two sessions, separated by 28 days.
Intra-class Correlation Coefficients (ICCs) and Coefficients of Variation (CoVs)
were calculated to determine test-retest reliability. For dynamic plantar
loading, reliability differed by outcome measure and foot region, with ICCs of
>0.8 and CoVs of <15% observed in most cases. For dynamic foot geometry, ICCs of
>0.88 and CoVs of <3% were observed for hallux angle, arch index and coefficient
of spreading, while sub-arch angle was less reliable (ICC 0.76, CoV 23%).
Overall, the current study observed high levels of
test-retest reliability which
were generally commensurate with that previously reported in healthy populations.
