- Primary Outcome Measures
Name Time Method The absence of post-caloric response in preoperative evaluation, contacted through caloric and rotatory chair test, resulted in a worse prognosis in the evolution of body balance over 1 year. Having been considered a significance level of 5% (? = 0.05) comparing pre and post IC evaluations.
- Secondary Outcome Measures
Name Time Method Improvement in balance followed the time frame proposed in the literature for central compensation mechanisms and it was verified by computerized dynamic posturography. When considering the condition 5 of CDP 5 we found a statistically significant numerical increase between day zero and day 120 (p = 0.013), 180 (p = 0.006) and 365 (p = 0.004).<br>;Cases of dizziness reported before CI and confirmed by clinical evaluation at the end of the study ameliorated in 11 patients (84.6%), worsened in 1 (7.7%)and remained unchanged in 1 (7.7%).
