RESUMO

The aim of this work was to investigate the relation of the vertical component of the ground reaction forces and the plantar pressure distribution during standing position, acting under the forefoot and the rearfoot, using high heel shoes and high heel simulators (wooden blocks of different heights and angles of heel support). The subjects were 30 symptom-free volunteer women, with no apparent foot and leg pathologies, with body mass index (BMI) up to 30 (Pollock, 1993) who are used to wear high heel shoes at least once a week. To obtain the relations on the weight force application and the pressure distribution under the feet the subjects were positioned standing over two force plates AMTI (Massachusetts, EUA, 1991) at 60Hz, synchronized with a pair of pedar mobile insoles (pedar novelgmbh 2005) at 50Hz. The foot was divided in two areas and data was acquired in 10 seconds of self balanced position. Significant differences between the means of vertical force and plantar pressure were found related to the heights differences and angle differences (p<0,001), at the wearing shoes situation and with the simulators. The results of force and pressure did not follow a linear relation but increased as the heel height support got higher in both situations.
