query: What is the degrees of freedom problem in motor control?
answer: The degrees of freedom problem, also known as the motor equivalence problem, states that there are multiple ways to perform a movement to achieve the same goal.  The nervous system must choose a particular motor solution each time it acts, due to the near-infinite redundancy of anatomical, kinematic, and neurophysiological degrees of freedom (DOFs) in the human body.
