Human gait is typically studied with clinical observation or in a gait laboratory. The first approach is rapid but subjective and limited. The second, while it is experimentally rigorous and provides voluminous amounts of quantitative data, is time consuming and expensive. Computer simulation may offer an alternative approach for both the analysis of normal gait as well as in modeling the effects of changes in joint mechanics, muscle strength, and orthotics use. Current simulation techniques, however, are limited in their ability to model the complex analysis necessary to study gait when it is altered by an abnormal joint or the compensatory actions of the body and other joints. Three-dimensional dynamic model simulations are attractive because they provide predictive information about a system that often can not be obtained experimentally. These simulations have the added advantages of being both adjustable and accessible to anyone through the Internet. Abnormal walking shows compensatory actions due to lost functions at diseased joints. The approach suggests that reduction methods for the great compensations according to the location and the degree of modeled diseased joints may be applicable to model analyses how the joint goes in the future by the overloads.
