[Influence of density of pressure sensors on parameters of plantar foot load--a pedographic comparison of 2pressure distribution recording platforms].
The present study aimed to establish whether a higher sensor density of 9 as compared with 4 sensors per cm2 would influence plantar pressure measurements. Twenty-seven subjects aged between 2 and 33 years were studied during free barefoot walking on an ST-4 and an ST-9 platform (Novel GmbH Munich). Most significant differences were seen in peak pressure values and contact areas of selected foot regions. However--with the exception of the toes--the differences were below 10%, so that they were not considered to be clinically relevant. Furthermore, the differences between the platforms revealed no age-related effects, so that the higher sensor density did not provide any further gain, even for the smaller feet of children.
