| Outline of Final Research Achievements |
The purpose of this study was to investigate the vibroarthrography (VAG) for classification of patients with knee osteoarthritis. Our findings were 1) the tibia is the most suitable location for classifying knee osteoarthritis based on VAG signals. 2) The features of VAG with knee OA were obtained from a range from 0 to 45 degrees during standing, and the average frequency was around 180 Hz. 3) T2mapping values of knee joint cartilage using MRI were not related to those features of angle and frequency. 4) For the impulse method, the capacity of vibration absorption in knee OA was decreased from 20 to 30 Hz compared to a healthy population.
