Objective：To develop a detecting and analyzing system of dynamic and static ground reaction forces when walking or standing.Method：A 3-D force platform for detecting the ground reaction forces and a special software for data acquisition,calculation and analysis were developed,Result：Using this system,the ground reaction forces in three directions during walking and the trace of center of pressure（COP） oscillation during standing on the platform can be detected. Some characteristic parameters such as the length and area of the trace of COP oscillation can also be obtained. Conclusion：After being added body balance test function,the conventional 3-D force platform equipment becomes much more functional and the application scope is extended.
