Índice de repetibilidade de pisadas para análise da pressão plantar na avaliação clínica da marcha em diferentes faixas etárias

Abstract

The use of baropodometry equipment has been used in order to evaluate the repeatability and changes of plantar pressure during walking. Although there are several studies on the subject, it is not yet clear how many footfalls need to be analyzed to minimize the effect of pressure variability plant during gait analysis. To determine the minimum number of footfalls to minimize the variability of plantar pressure during gait of children, adults and seniors. The study included children aged 08-12 years, adults 30 to 45 years and seniors over 65 years of age, who walked barefoot in preferred speed, on a path of 9 meters. The gait assessment involved a day to familiarization, and two days of data collection. The plantar pressure was analyzed by a baropodometro being recorded 10 Stepped data. The peak plantar pressure was determined for the regions of the forefoot, midfoot and hindfoot. Variability in peak pressure was determined from the standard deviation considering combinations of two to ten footsteps. Analysis of Stepped number can be concluded that 10 footfalls, 4 were able to obtain a less variable pattern of peak pressure in the march of children, adults and healthy older adults. The minimum number of 4 footsteps to determine the peak pressure is suggested by our results, and this suggestion proved valid for assessments on different days.
