Cervical Vertebral Problems as A Cause of Variations in the Nystagmographic R-Factor

Abstract

All patients who complained of dizziness during 1981 and in whom the nystagmograms indicated either central damage or were found normal, were investigated further regarding changes in their R-factor (an expression for amplitude). This was deduced from the nystagmographic readings produced by caloric testing in these patients. It was thus found that patients with pain or stiffness in the neck had a significantly raised i?-factor in all age groups.
