The physics of spinal manipulation. Part II. A theoretical consideration of the adjustive force.
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.
