Abstract
The purpose of this study was to compare the peak pressure and peak force values obtained from two pressure assessment systems, the Dynamic Pedobarograph and the EMED SF. Twenty-one individuals with a mean age of 31.6 years walked barefoot over both systems using a two-step data collection protocol. Peak plantar pressures and peak vertical force values were measured under the heel, central forefoot, hallux, and entire foot for both systems. The results of this study demonstrated that the EMED SF system produced larger peak pressures under the central forefoot and hallux. The Pedobarograph, on the other hand, produced greater pressures under the heel and entire foot. With respect to peak vertical forces, the Pedobarograph showed significantly greater values under the heel and central forefoot compared with the EMED SF, but were significantly lower under the hallux and entire foot.
