Purpose of the Study:

  • To present a novel conceptual framework for movement termination.
  • To elucidate the roles of center-of-mass position and velocity in controlling movement cessation.
  • To analyze the implications and constraints of this framework for physical rehabilitation.

Main Methods:

  • Conceptual review and framework development.
  • Analysis of existing literature on motor control and biomechanics.
