Abstract:

BACKGROUND: The study of the relationship between knee and ankle is poor although there have been a lot of researches on gait of people.
OBJECTIVE: To analyze the relationship between knee and ankle based on back-propagation network.
METHODS: The gaits of 30 healthy young people walking at fast, normal, and low speeds separately were detected by three-dimensional gait analysis system, and the gait data were investigated and analyzed. The data were predicted through the establishment of the back-propagation neural network and the knee-ankle coordination control method was explored.
RESULTS AND CONCLUSION: Different people had different gaits, but the curve obtained by back-propagation neural network was similar with the experimental curve. The paper investigated and validated that it was viable and reasonable to forecast the kinematic relationship between the knee and ankle by back-propagation network system. The paper studied the coordination between the knee and ankle well, and provided the theory foundation for the design of the intelligent prostheses.
