Inverse dynamics

Inverse dynamics is a method used in biomechanics and robotics to determine the forces and moments acting on a body or system based on its movement. By analyzing the motion—such as joint angles and accelerations—it calculates the muscular forces or motor torques needed to produce that movement. Essentially, it works backwards from observed motion to understand what forces must be involved. This approach helps in fields like rehabilitation, sports science, and robotics to assess performance, improve designs, or develop effective treatment plans.
