Analyses of Plantar Foot Pressure and Static Balance According to the Type of Insole in the Elderly

Methods: Thirteen elderly (mean age: 67.08±2.25 years, mean height: 159.63±9.64 cm, mean body weight: 61.48±9.06 kg) who had no previous injury experience in the lower limbs and a normal gait pattern participated in this study. Three models of insoles of the normal, 3D, and triangle types were selected for the test. The Pedar-X system and PedarX insoles, 3.3 km/h of walking speed, and a compilation of 20 steps walking stages were used to analyze foot-pressure distribution. Static balance test was conducted using Gaitview AFA-50, and balance (opening eyes, closing eyes) was inspected for 20 s. Oneway ANOVA was conducted to test the significance of the results with the three insoles. P-value of less than .05 was considered statistically significant.
