GAITREC: A Data Treasure for Gait Analysis

To facilitate research, therapy, and diagnosis, FH-Prof. Dr. Brian Horsak and his colleagues at the St. Pölten University of Applied Sciences (UAS), Austria, and the Austrian insurance institution AUVA have published one of the biggest data records worldwide on gait analysis. The data include anonymized information on over 2,000 patients after joint transplantations, fractures, and ligament injuries, as well as associated impairments of the hips, knees, ankles, and heel bones. The data come from several years of clinical gait analysis practice and can be used to improve analysis procedures and models. The database, called GAITREC, is available online free of charge.

The database comprises information on ground reaction force (GRF), which is the force between the foot and the ground that is generated during movement. It is an important standard parameter used in clinical practice and in research. The figures form the basis for diagnosis and for the assessment of therapeutic success.

“Gait analysis provides a huge amount of data,” said Horsak, head of the research focus Motor Rehabilitation at the St. Pölten UAS. “Their interpretation is challenging and there is a great deal of interest in supporting medical decision-making processes with machine learning methods. The more data we have, the better the results.”
