Farklı Eksternal Destaklerin Ayağın Pedobarografik Parametrelerine Etkisinin Incelenmesi

Abstract

The purpose of this study was to investigate and compare the effects of elastic tape, non-elastic tape and insole which are used to prevent excessive rearfoot pronation on plantar pressures. 21 women and 6 men, total 27 subjects with an age range of 19-45 years, who were diagnosed as having excessive rearfoot pronation were included in this study. Demographic data of subjects were recorded and Short Form McGill Questionnaire, Navicular Drop Test, subtalar joint range of motion measurement, muscle strength and shortness measurement, Foot Posture Index and Foot Function Index were performed before external support applications. Subjects were applicated elastic tape, non- elastic tape and insole; their static and dynamic plantar pressures were assessed in four different formats, barefoot and with those applications, with computerized pedobarographic technique. On static position, there were statistically significant decreases at peak pressures with insole, according to other conditions (p<0,001), despite there were no significant differences at contact area percents of forefoot and rearfoot between the four conditions (p>0,05). On dynamic position, there were statistically significant increases at total contact area, contact area and impuls percents of midfoot (p<0,001, p=0,001), significant decrease at contact area percents of forefoot and rearfoot (p<0,001) with insole, significant decrease at contact area percents of right forefoot with elastic tape application according to barefoot, at impuls percents of left forefoot with insole according to elastic tape application (p=0,006, p=0,004), significant decrease at maximum subtalar joint motion of left foot with non-elastic tape application according to barefoot and with insole condition (p=0,004, p=0,008), significant decreases at maximum pressures of 2.,3. and 4. metatars areas of left foot with insole according to barefoot (p=0,007, p=0,001, p=0,003), at maximum pressures of 2. metatars areas of right foot with insole according to other conditions (p<0,001, p=0,002), significant increase at maximum pressures of left midfoot area with elastic tape application according to barefoot (p=0,005), significant decrease at left and right, medial and lateral heel areas with insole according to other conditions (p<0,008). There were no statistically significant difference at impuls percents of left and right rearfoot and right forefoot, at left and right foot axis angles, minimum subtalar joint motion, maximum subtalar joint motion of right foot, at maximum pressures of 1. toe, 2.,3.,4. and 5. toes, 1. and 5. metatars areas of left and right foot, 3. ve 4. metatars areas of right foot between four conditions (p>0,05). The result of this study indicates that insole, one of the external supports which are used to prevent excessive rearfoot pronation, is more effective to distribute plantar pressures and prevent excessive loading of specific areas by increasing contact area.
