Neck afferents not only assist the coordination of eye, head, and body, but they also affect spatial orientation and control of posture. This implies that stimulation of, or lesions in, these structures can produce cervical vertigo. In fact, unilateral local anesthesia of the upper dorsal cervical roots induces ataxia and nystagmus in animals, and ataxia without nystagmus in humans. If cervical vertigo exists outside these experimental conditions, it is obviously characterized by ataxia and unsteadiness of gait, and not by a clear rotational or linear vertigo. Neurological, vestibular, and psychosomatic disorders must first be excluded before the dizziness and unsteadiness in cervical pain syndromes can be attributed to a cervical origin. To date, however, the syndrome remains only a theoretical possibility awaiting a reliable clinical test to demonstrate its independent existence.
颈部传入神经不仅有助于眼睛、头部和身体的协调，还会影响空间定向和姿势控制。这意味着刺激这些结构或这些结构发生病变会导致颈性眩晕。事实上，对上颈背神经根进行单侧局部麻醉会在动物身上诱发共济失调和眼球震颤，而在人类身上则诱发无眼球震颤的共济失调。如果颈性眩晕存在于这些实验条件之外，其明显特征是共济失调和步态不稳，而非明显的旋转性或线性眩晕。在将颈痛综合征中的头晕和不稳归因于颈部原因之前，必须首先排除神经、前庭和身心障碍。然而，迄今为止，该综合征仍然只是一种理论上的可能性，有待可靠的临床测试来证明其独立存在。
