Abstract

The purpose of this study is to investigate data clustering to determine representative patterns in 3D knee kinematic data. The method reduces data dimensionality by isometric mapping and clustered them by the DBSCAN algorithm. Clusters are validated in terms of the silhouette index, the Dunn index, and connectivity. Results show that a two-cluster characterization of the kinematic knee data in each plane is quite effective. Clinical investigations show that the men and women knee patterns are balanced between the two clusters and, for 80% of participants, the right and left knees are in the same cluster.
