Deficits in cervical joint position sense, eye movement control, and postural stability are often noted in patients with traumatic neck pain and cervicogenic dizziness due to abnormal cervical afferent input.

Saccadic eye movement describes rapid eye movements used to change a point of fixation. Without moving the head, the patient is instructed to follow and fixate on a target about 3 feet (or 1 meter) away that is quickly moved and then held still momentarily. The patient's ability to quickly move to the target and fixate on it is noted.

Another option is to hold two targets in front of the patient at eye level, at a distance of about 3 feet (or 1 meter) and approximately 12 inches (or 30 centimeters) apart. The patient is then instructed to look quickly from one target to the next as quickly as possible. Inability to maintain focus on the target, overshooting or undershooting, and symptoms such as dizziness, blurring of vision, or nausea are considered abnormal responses.
