The effects of manipulated dental occlusion on body posture has been investigated quite often and discussed controversially in the literature. Far less attention paid to influence position human movement. If movement was analysed, it mostly while walking not running. This study therefore designed identify effect lower jaw positions running behaviour according different positions.Twenty healthy young recreational runners (mean age = 33.9±5.8 years) participated this study. Kinematic data were collected using an eight-camera Vicon motion capture system (VICON Motion Systems, Oxford, UK). Subjects consecutively prepared with four conditions random order performed five trials per test condition a level walkway their preferred shoes. Vector based pattern recognition methods, particular cluster analysis support vector machines (SVM) used for identification.Subjects exhibited unique patterns leading 18 clusters 20 subjects.
