The average adjustive force is shown to be an explicit function of the doctor's mass, the doctor's impact velocity, and the intrinsic stiffness and elasticity of the doctor and patient. A simple model is used to derive an adjustive force equation. The generalization of this equation to actual manipulative technique is also explored.
