Why are smooth-pursuit and/or saccadic eye movements assessed after a whiplash injury?

• A. To predict persistent disability at 8 months
• B. To determine pain level
• C. To assess neck reflexes
• D. To predict cognitive decline

Answer: (A)

Evaluating smooth-pursuit and saccadic eye movements after a whiplash injury taps into how well the brain and neck sensory systems are coordinating eye control. These eye movements rely on intact cerebellar and brainstem pathways and accurate neck proprioceptive input to keep gaze stable and to quickly and accurately shift focus. When abnormalities appear, they often reflect impaired sensorimotor integration that can be associated with slower recovery and a higher risk of ongoing disability several months after the injury. That prognostic value is why these tests are used: they help identify individuals who may have persistent disability around eight months and guide targeted rehabilitation. They aren’t primarily used to gauge pain levels, assess neck reflexes, or predict cognitive decline, which involve different assessment domains.
