Foot pronation detection based on plantar pressure measurement

Abstract

In the paper, we design a foot pronation detection system based on plantar pressure sensors. The system includes: collecting the pressure sensor signals by reasonably arranging the pressure sensors; collecting the plantar pressure signal value of the test object which has been walking for a period of time; taking the proportional calculation,determining the fuzzy sets,designing the membership function, the fuzzy processing was carried out and the fuzzy rules was established by the IF-THEN rules. Finally the gait phase was deduced according to the fuzzy output signal, and the system function was realized by pronation analysis algorithm. The experimental results show that the system has an important value for sports risk prediction.
