The Technology of Merging Single Force Plate Gait Trails to Simulate Full Gait Cycle in Environmental Health Research

Abstract:

The article studies the way of combining double foot data into one gait cycle from data collected from only one force plate, and the reliability with comparing the Root Mean Square Error (RMSE) between combined and original trails is validated. The joint moment values, knee muscles value were also computed by OpenSim based on the dynamic model. Correlation coefficients and normalized RMSE were used as the compared factors between two trails. Correlation coefficients are all above 0.9 for joint moments, and all above 0.95 for knee muscles except for biceps femoris - long head. The technology would get higher reliability and improving the accuracy of simulation result by increasing the numbers of collection trails and selecting pairs trails which got higher correlation coefficients.
