[EVALUATION OF THE DIZZY PATIENT - FROM THE VESTIBULAR IMPAIRMENT TO THE PATIENT'S FUNCTIONAL ABILITY].

INTRODUCTION: The vestibular system - the sixth sense - allows humans to preserve balance, stable vision, and body orientation in space. This system performs a continuous integration of the activity of the vestibular end-organ in the inner ear, the sense of sight, and the proprioceptive sense. Damage to the components of the vestibular system causes dizziness, imbalance, and poor orientation in space. Following vestibular injury, central compensation mechanisms are recruited to reduce the symptoms and improve the functional ability of the dizzy patient. Dizziness is a subjective complaint. Yet, the development that has taken place in the field of vestibular function testing allows accurate diagnosis, targeted treatment, and disability assessment of the dizzy patient. The dizzy patient must be examined meticulously, taking into account all the levels on which the vestibular impairment can affect (physiological, behavioral, and functional). Meaning, clinical and laboratory evaluation of the vestibular function together with functional testing of the patient. In this article, the authors present the range of existing innovative tests of the vestibular system. Vestibular tests are accepted in advanced vestibular laboratories in Israel and around the world, and enable assimilation in vestibular clinics and medical committees in Israel.
