Balance impairment is the object of requests for remuneration in 20-50% of the cases of cranial trauma.

This means that the lesions detected solely through vestibular testing are not necessarily indicative of the extent to which the subject is affected. Furthermore, some extravestibular lesions can give rise to balance impairments which will go undetected by vestibular examination. Finally, an universally accepted diagnostic protocol still doesn't exist. In this work the Authors present a new method for balance impairments evaluation. While this technique still involves the normal evaluation range for vestibular damage (1-25%), it is based on the disturbance indicated by the patient rather than on the instrumentally detected damage. To objectively determine the real existence of the symptom, the Authors also propose a specific diagnostic strategy for each symptom, thus overcoming the problem of a diagnostic standard. The initial results, obtained on 56 subjects evaluated for post-traumatic balance impairment, show substantial agreement with previous methods. Our method allows to better recognize modest damage--for the most part extravestibular which go unrecognized with the conventional methods--and significantly modify the amount of more extensive damage, expression of vestibular damage which does not correspond to equally significant symptoms.

Abstract

Balance impairment is the object of requests for remuneration in 20-50% of the cases of cranial trauma. Most patients present slight disequilibrium following cranial traumas not involving concussion or cervical distraction. The various methods used in Italy to evaluate the biological damage score balance annoyances on a percentage basis ranging from 1% to 25% and base evaluation on vestibular testing results. The Authors feel that such evaluation approaches are limited. Indeed, since compensation mechanisms come into play, vestibular lesions are not always symptomatic. This means that the lesions detected solely through vestibular testing are not necessarily indicative of the extent to which the subject is affected. Furthermore, some extravestibular lesions can give rise to balance impairments which will go undetected by vestibular examination. Finally, an universally accepted diagnostic protocol still doesn't exist. In this work the Authors present a new method for balance impairments evaluation. While this technique still involves the normal evaluation range for vestibular damage (1-25%), it is based on the disturbance indicated by the patient rather than on the instrumentally detected damage. To objectively determine the real existence of the symptom, the Authors also propose a specific diagnostic strategy for each symptom, thus overcoming the problem of a diagnostic standard. The initial results, obtained on 56 subjects evaluated for post-traumatic balance impairment, show substantial agreement with previous methods. Our method allows to better recognize modest damage--for the most part extravestibular which go unrecognized with the conventional methods--and significantly modify the amount of more extensive damage, expression of vestibular damage which does not correspond to equally significant symptoms.
