In considering the inverse dynamics equations, the underestimation of segment mass results in errors when calculating net joint forces, due to the large force created from acceleration of the segment.
Inverse dynamics were used to calculate three-dimensional moments at the hip, knee, and ankle joints.

The process used to derive these parameters is known as inverse dynamics, because one can work back from the kinematic, anthropometric, and externally measured force data to derive the kinetics responsible for the motion.
