Summary : Objective: What is the status of postural control a few months after an attack of vestibular neuritis (VN)? Using dyna­mic posturography and stabilometric signal treatment with wavelets and fractal analysis, we tried to answer this question by isolating the pathological postural parameters of VN. Mate­rial and method: The study involved a group of 15 patients (GP) who suffered from VN and were compared to a group of control subjects (GC). Both groups underwent video­nystagmo­graphy (VNG), dynamic posturography (PDY), and assessment using symptomatic scales (ES). Results: GP and GC were compa­rable in terms of age mean, sex-ratio, average height and weight. The differences between GP and GC were the following videonystagmography criteria: spontaneous nystagmus (NS) (P= 0.005), head shaking test (HST) (p= 0.001), vibratory test (TVO) (p= 0.009). There were also differences in the sympto­ma­tic scales scores for the vertigo symptom scale (VSS) (p= 0.011), the dizziness handicap inventory (DHI) (p= 0.001), and the short form 36 (SF36) (p= 0.01). All the 84 new para­meters of both GP and GC differ. This difference was significant (p< 0.05) in 16 cases (19%), and highly signi­fi­cant (p< 0.01) in 11 other cases (13%). The condition «unstead­y platform» was the greatest determinant in both groups while the «closed eyes» and «HST» conditions were found to be non-discri­minating. Conclusion: Vestibular neuritis affects new stabilo­metric para­meters. These parameters are more adapted to the present set-up compared to previous parameters which are used to analyse non-periodic oscillations of posture. They are important in follow-up and rehabilitation of patients.
