No full textAcute vestibular injury, such as vestibular neuritis (VN), can produce a profound
alteration in balance manifested by perception disorder and impaired control of
postural adjustment and execution of movements. Stabilometry assesses posture
balance through the quantification of body oscillations from the orthostatic position in
a force platform. It involves monitoring center of pressure (COP) displacement to the
lateral direction (X) and anterior-posterior direction (Y). In our study we investigated
the postural control of patients affected by VN. We analyzed 30 subjects: 15 patients
constituted the case group affected by VN were compared with 15 healthy volunteers.
A static posturography was made within 6-24 hours of symptoms onset. Our purpose
was to assess the use of posturography Fourier Frequency analysis with head tilt for the
detection of peripheral vertigo destabilization. Fourier spectral analysis of body sway
reveals that, independently from visual control, patients exhibit a significantly higher
level of low/middle frequency oscillations on the frontal plane. The macular stimulation
by head tilt increases significantly the difference in all analyzed parameters: there are
significant differences of body oscillation in the patients vs controls on X and Y planes,
the latter evident only in head tilt tests. The head tilt seems to show an antero-posterior
plane destabilization otherwise not evident
Auditory brainstem and cochlear implants: functional results obtained after one year of rehabilitation
No full textVery little information has been published on the clinical outcome of auditory brainstem implants (ABI). The present paper evaluates results obtained in a patient affected by a bilateral acoustic neuroma in type II neurofibromatosis who received an implant during removal of the residual tumor. One year later surgical revision of the ABI was necessary because no auditory sensation was obtained after ABI activation. Twelve months after the surgical revision, 12 electrodes out of 15 evoked auditory sensation. The results of rehabilitation were compared with those obtained in a group of eight postlingually deaf patients with cochlear implants (CI). Twelve months postoperatively the CI patients identified 97.7 +/- 5.1% of bisyllabic words in a closed set while the ABI patient identified 86%. CI patients recognized 87.1 +/- 11.3% of sentences and 81.3 +/- 14.8% of words with contextual cues while the ABI patient recognized 75% and 65% respectively. Speech recognition improved more slowly in the ABI patient than in the CI patients and his scores for open-set words and sentences without lip reading and contextual cues were poorer. Although the results obtained in the ABI patient were not as good as those obtained in the CI patients, the ABI patient said his quality of life was improved
