| Sumario: | The complex integration between the vision, proprioception, and vestibular systems provides the foundation for postural stability, gait patterns, and many visual functions. Such visual functions include conjugate eye movements, vergence, and stability of gaze as the head, body, and/or target moves. These processes are facilitated by magnocellular pathways in the brain. The magnocellular system is particularly susceptible to dysfunction from a concussion, which can result in a variety of symptoms characteristic of Post-Trauma Vision Syndrome. Whiplash cervical injury without direct head trauma can arguably be considered to be a cause of concussion due to a similar profile of signs and symptoms as traumatic brain injury from direct head impact. Cervical afferent changes that occur from whiplash can produce sensorimotor disruption and thus affect those visual functions that are influenced by proprioceptive input from the neck. As can be seen, rehabilitation of visual function following whiplash injury requires a multi-disciplinary collaborative effort to facilitate the variety of sensory inputs needed for these processes to occur accurately and effortlessly.
