To explore the usefulness of LBT and RNG for the diagnosis of dizziness. In addition to the conventional evaluation methods, LBT and RNG are evaluated and analyzed with dizziness symptoms and vestibular function test results.
Efficacy
Measurements of LBT and RNG (mean, standard deviation, R score, RNG score, RNG 2 score, FODs, Ac score) and center of gravity sway test (total locus length, velocity Romberg rate (rubber), closed eye rubber ratio (velocity), (Gravichart type), Caloric test (maximum slow phase velocity, CP%), cVEMP (p13-n23 amplitude), oVEMP (n1-p1 amplitude), DHI, SDS, GDS, HADS correlation coefficient or ratio
Measurements of LBT and RNG (mean, standard deviation, R score, RNG score, RNG 2 score, FODs, Ac score) and age, gender, diagnosis, dominant hand, dominant eye, hearing test (standard pure tone hearing test, inner ear function Examination, gaze nystagmus, head nystagmus, head position change nystagmus, stepping test, spontaneous nystagmus, follow-up test, two-point alternating gaze test, correlation coefficient or correlation with visual motor nystagmus (OKN) ratio

(1) Line segment bisecting task
Perform the test with the application software installed on the computer.
1) Place the examinee's chin on a chin stand 60 cm away from the LCD monitor to fix the face position.
2) Ask the subject to see the cross-shaped figure displayed in the center of the LCD monitor and adjust the position so that the eye level and the center are aligned.
3) Make the examination room dark.
4) Explain to the subject that the quadrangle displayed on the LCD monitor is halved in horizontal length regardless of the shape of the figure. Regarding the operation, the vertical line segment is moved by moving the mouse, and the position is determined by left-clicking. The quadrangle is a rectangle and is rotated 0degrees, 15degrees, 30degrees, 45degrees, 60degrees, 75degrees, 105degrees, 120degrees, 135degrees, 150degrees, 165degrees to the right around the long side bisector. 11 patterns are displayed. The vertical line segments are displayed from the upper left, lower left, upper right, and lower right outside the figure from the four patterns. Test a total of 44 squares with 11 patterns and 4 vertical line segment display positions. No specific explanation will be given to the subjects.
5) Conduct 4 exercises and start the test if there are no questions.
6) Measure the time taken for the test.
7) Confirm and record the dominant hand and dominant eye.
The average and standard deviation of the deviation from the center of the division position is calculated for each of the 11 types of figures.
(2) Random number generation task
1) Randomly tell the inspector a number from 1 to 9 as quickly as possible.
2) First, practice for 15 seconds, and then do the final test for 2 minutes.
3) Record the vocal data with an IC recorder and transfer the data to a computer for storage.
4) After the inspection, the inspector writes down the data. The utterances that do not match the conditions are saved as blank.
5) Use a separate explanation sheet.
