[Reading test as a qualitative method for evaluating the vestibulo-ocular reflex].
In the reading test the patient reads a text while his or her head is passively moved from one side to another with a frequency over 2 Hz. The vestibulo-ocular reflex (VOR) should stabilize the patient's gaze if it is performing adequately, allowing him or her to read well. Reading becomes impossible if the VOR is defective. We tested this method by assessing VOR in a 30-patient series by means of VAT and a previous reading-test score, and we compared the results of both groups. Next, the test was clinically validated with the bithermal caloric test. There were significant differences in ocular asymmetry between normal and strongly positive groups. The sensitivity, specificity, and positive and negative predictive values validated the reading testing as clinically useful.
