Abstract
The righting reflex and deviation phenomena of the limbs and body and the spontaneous nystagmus were examined in patients with vertigo and normal persons. The diagnostic significance in these examinations was discussed. The conclusions were as follows:(1) Positive findings (tendency to fall or unstableness of the body) in the standing test with eyes closed and the standing test on one foot with eyes open as well as closed in patients with vertigo appeared at a higher rate than in normal persons.(2) Appearance of staggering in stepping test and of ataxic letters in vertical writing was significantly different between the vertigo cases and the normal persons. In the normal persons these findings were not seen at all.(3) Nystagmus in gaze, positional and positioning nystagmus tests were not found in normal persons at all, while noticed at a high rate in the patients with vertigo. So these tests mentioned in (1),(2) and (3) are available for the diagnosis of vertigo.(4) No significant difference was noticed in deviation in stepping test and vertical writing test between the patients with vertigo and normal persons. So deviation phenomena are not appropriate to objectify vertigo.(5) Significant relations were not found between the direction of nystagmus and of the deviation in stepping test and vertical writing test.
