It is well known that diseases of the vestibular system can be compensated by increased spontaneous activity of other systems engaged in maintaining equilibrium, i.e. proprioceptive and visual systems. A complex approach using multisensory stimulation is the optimal way to achieve vestibular compensation.
The aim of our study was to determine the effect of vestibular rehabilitation therapy as measured by posturography in a group of 72 patients suffering from vestibular disorders: Ménière's disease (n = 31), neuritis vestibutaris (n = 21) and vertebrobasilar insufficiency (n = 20). Patients underwent the following examinations: electronystagmography; caloric, rotatory and optokinetic tests; computed posturography; craniocorpography; pure-tone audiometry; speech audiometry; and tinnitometry (tinnitus loudness, pitch).
The instability in patients with Ménière's disease decreased 3 weeks after starting the therapy; nevertheless, the decrease in area (the surface formed by the movement of the patient's equilibrium point during a defined time) was transitory because of the increase in area values obtained between the 3rd and 6th weeks when measured with closed eyes. In the vestibular neuronitis patients, the measured values of area and the velocity of the patient's movement decreased continuously.
The values measured in the patients suffering from vertebrobasilar insufficiency decreased continuously, the absolute values remaining pathological.
