Abstract Summary
Differences in predicted hip joint center (HJC) locations can affect the calculation of lower body dynamics related to daily living. This research compared kinetic output from models using the Seidel and Harrington HJC predictive methods. In normal healthy adults, there were significant differences in hip and knee moments during the stance phase of gait in all three planes. Since the Harrington predictive method compares most favourably with gold standards, it appears that the Seidel predictive method may be less useful in clinical gait analysis.
