What is the purpose of the gaze stability test in cervical proprioception assessment?

• A. To assess the ability to fix on a stationary object while the head moves
• B. To measure neck strength
• C. To evaluate auditory processing
• D. To assess balance on a foam surface

Answer: (A)

Gaze stability during head movement is controlled by the cervico-ocular reflex, which uses neck proprioceptive input to help the eyes stay fixed on a target as the head moves. The gaze stability test in cervical proprioception assessment measures exactly that: the ability to keep visual fixation on a stationary object while actively moving the head. A good performance indicates that neck sensory information is properly integrated with eye and vestibular systems to stabilize gaze. If cervical proprioception is impaired, fixation can drift or require extra effort to maintain, revealing deficits in neck proprioceptive input. This differs from neck strength testing, which focuses on muscle force; it isn’t about auditory processing or about balance on an unstable surface.
