Objective. The purpose of this study was to recognize gait pattern in ankle arthrodesis by using a neural network trained with time domain input and compare the performance of the neural network with the statistical method.Design. Three-layered feed-forward back propagation neural network and a statistical method were used to classify gait patterns of patients with ankle arthrodesis and normal subjects.Background. Although backpropagation neural networks are very efficient in many pattern recognition tasks, they have not been used for gait pattern recognition of ankle arthrodesis.Methods. A total of eighteen parameters measured by force platforms, including nine force parameters and their chronologic incidence of occurrence, were used to classify gait patterns.Results. The results showed that the neural network model was able to classify subjects with recognition rates up to 95.8%. In contrast, the statistical method was only able to classify the subjects with recognition rates of 91.5%.Conclusions. The backpropagation neural network method has better accuracy than the statistical method in discriminating subjects and the time domain features carry important prognostic information.RelevanceIt is important to be able to quantify the changes in gait pattern after arthrodesis to understand the clinical implications of arthrodesis.
