Customized orthopedic insole design and analysis

In this thesis study, it was aimed to carry out an effective method and analysis in the production of private orthopedic insoles at low cost. For this purpose, the upper and lower parts of the foot were examined in two separate works using different sensors. In the first study, a thin film pressure sensor was used for flatfoot and normal foot sole analyzes. Five different regions were selected on the right sole for pressure measurements. 12 women and 5 men volunteers participated in the pressure measurements applied to the sole, including men and women aged 19 to 34 years, with flatfoot and normal foot. In addition to this work, the reduction degree of pressure applied to the sole of a 9 mm high foam material placed on the heel of the foot was measured. Secondly, the angular rotation of the tibia was analyzed with a GY-521 gyroscope sensor placed on the talus during two-step walking. The angular measurement values were taken with gyroscope sensor on the feet of 12 volunteers (24 feet). The data and results obtained from both studies were compared with the study data and results of other researchers. The relation of these results to the flatfoot was stated and interpreted. In summary, the pressure values and the pressure distribution percentages that obtained for the 5 foot sole regions relation with each other and the body mass index were statistically examined.
