Kinematic Parameters to Predict Knee Diseases.
2017. május 17. frissítette: Yu Zhang, Guangzhou General Hospital of Guangzhou Military Command
Can Gait Parameters Predict Knee Injuries/Arthritis?
There is no study to explore the prediction of knee diseases using kinematic parameters of knee during gait.
The aim of this study is to explore the possibility of predicting knee diseases by gait parameters.
