Abstract
:

Osteoarthritis is a degenerative joint disease, which causes the degradation of articular
cartilage and subchondral

bone. The disease may result in mechanical abnormalities of the
joints, including weight bearing joints such as the knees and hips. In this work, we analyze
gait biomechanical data using neural network models to predict the level of joint
deterioration an
d the level of pain in participants suffering from knee OA. The results of the
analyses demonstrate strong correlation between gait kinetics and joint deterioration and
level of pain in osteoarthritic individuals.
