The control of movement provides us with the ability to manipulate and move about within our environment, to satisfy our survival needs and to interact with each other. Motor control is also the process by which we express our sameness and uniqueness within our society. Changes in motor control brought about by damage to our central nervous system, therefore, alter who we are in quite profound ways. This chapter focuses on the results of damage to the spinal cord and how output from the brain and brain stem to the spinal neural circuits, the motor neurons, and muscle fibers that they activate is altered. It covers the essentials of measuring motor control using functional electromyography, the characteristics of non-injured motor control, the characteristic patterns of motor control in chronic spinal cord injury (SCI), and selective control of voluntary movement disrupted by SCI.

Keywords: motor control; spinal cord damage; brain stem spinal neural circuits; motor neurons; muscle fibers
