Vertigo is a sensation of spinning, tilting, or motion when no actual movement is occurring. It most commonly stems from dysfunction in the vestibular system of the inner ear, but it can also be influenced by visual input and neck (cervical) proprioception. When these systems don’t agree, the brain receives conflicting information, leading to dizziness, imbalance, nausea, and sometimes headaches or neck tension.
Combining Brock string convergence/divergence work with controlled head movement helps retrain how the visual, vestibular, and cervical systems communicate. The eyes learn to maintain accurate focus and depth perception while the head moves, which mirrors real-life demands like walking, driving, or turning quickly. This integration can calm an overreactive vestibular system, reduce visual dependency, and normalize neck proprioceptive input—often leading to improvements in vertigo symptoms, decreased neck pain from reduced guarding, and fewer headaches caused by visual strain or sensorimotor mismatch.
