title: Normative data of videonystagmography in young healthy adults under 40 years old.
abstract: OBJECTIVE
  The purpose of this study was to establish a set of normative data values for saccade movements using videonystagmography and to evaluate the effects of manual correction on this data.
  
  
  METHODS
  We examined 25 healthy subjects (9 men and 16 women). All tests were carried out by one well-instructed physician. Errors such as the wrong detection of the inflection point, missing movement, and prediction occurred during some tests. Thus, the same physician manually corrected the data by deleting error data from row results.
  
  
  RESULTS
  We established a set of normative data for horizontal saccade movements (amplitude size 15 and 30 degrees) for mean peak velocity, latency, and accuracy. Manual correction only impacted latency and accuracy at 30 degrees horizontal, which is likely related to possible errors during the test.
  
  
  CONCLUSIONS
  The present study provides clinically useful videonystagmography-based normative data for clinicians regarding saccade movements in Korean individuals.
