Analysis of foot pressure distribution data for the evaluation of foot arch type

In order to develop an evaluation system for foot arch type in the elderly using foot pressure distribution data, foot pressure distribution parameters were selected and the data thereby derived were discussed. Results from the study show that the midfoot area and pressure ratios were correlated to foot arch type determined by visual analysis and were not correlated to arch height parameters. It is assumed that foot pressure distribution parameters reflect a different phenomenon from that of arch height parameters. The inconsistency between them is considered to be a result of the effect of the forefoot arch on the arch height parameters.
