BACKGROUND
It is well known that many patients with vertigo become vertinous when all alteration o the body position occurs while either head-shaking or after standing up. Posturaphy conducted with those patients when standing still is thus not always successful in detecting abnormal symptoms However. such abnormalities can be easily detected when the patients are subjected to motion-stress, such as head -shaking or alterations of the body position. The effect of such motion-stress on the disturbance of the centroid in normal individuals has yet to he clarified.
METHODS
In this study, posturography was conducted normal subjects who were subjected to motion-stress in the manner mentioned above and the results of this test were then compared with the findings of a conventional test.
RESULTS
Through this comparison no increase in the unbalance, as a result of the applied motion-stress, was observed for the X distance(XD), Y distance(YD) and Length(LNG). However, a significant increase in the imbalance was found for the XD and LNG itt (lid subjects.
CONCLUSION
Therefore, motion-stress, such its head-shaking or alterations of the body position can be helpful in detecting vertiginous symptoms in vertigo patients. But in the elderly patients the merit of above stimuli during the test should be vet clarified |
