A concussion can occur as a result of a hit to the head, or forces causing a sudden jolt to the head such as whiplash or blow to the body. Loss of consciousness is not necessary for a concussion to occur. In fact, only 10% of individuals who sustain a concussion lose consciousness.

Vestibular Rehabilitation is a specialized form of therapy that focuses on addressing the primary and secondary problems resulting from vestibular disorders. It is primarily an exercise-based rehabilitation program that addresses symptoms associated with vestibular disorders, such as vertigo, dizziness, imbalance, and visual disturbances.

The Vestibulo-Ocular Reflex (VOR) is a reflex that produces compensatory eye movements in response to head movement. The eye movements are equal in amplitude and speed to the head movement but in the opposite direction. The goal of this reflex is to ensure a stable gaze during head movements to minimize the blurring of visual targets perceived in the environment.
