[The usefulness of posturography and caloric tests in selected neurological diseases].

BACKGROUND
Many functions are disturbed after stroke.


THE AIM
Of the research was to evaluate the usefulness of static posturography and caloric tests in the rehabilitation of postural stability disorders.


MATERIAL AND METHODS
It was examined in 40 patients with cerebral stroke as compared with 40 healthy subjects. Based on selected stabilographic parameters it was investigated whether there is a difference in body deflection between patients and healthy individuals. The effect of visual control on stability was analyzed. The research was carried out with the use of static posturography and the standard set of tests.


RESULTS
It has been shown that the postural stability of patients with stroke is characterized by a larger surface area of the stabilogram and a greater total length of deflection than of healthy individuals. It was observed that patients with stroke suffer the most significant deterioration of posture stability both with conscious visual control and without it. After examination of the patients before and after rehabilitation and having analyzed the coordination index, it has been proved that rehabilitation has a positive influence on the stability of posture in healthy controls. It has been proved that caloric tests performed in patients with damage to the central nervous system did not have an influence on the evaluation of the progress of rehabilitation.


CONCLUSIONS
Post stroke postural stability disturbances are worsening without visual control and increased after rehabilitation.
