Abstract
The aim of this study was to evaluate the equilibrium of the active rotational head movement. The balance and function of the active rotational head movement was examined in 35 healthy volunteers and 12 subjects with vestibular neuritis in the compensation phase using a stabilometer. The load and locus were separately evaluable in each extremity using this stabilometer. There was no statistically significant difference in the stabilometer score between the rotation to footedness and the other side in the healthy volunteers group. In the group of vestibular neuritis, the maximum load factor on the rotation side was significantly larger, and the minimum load factor on the oppose side was significantly smaller, than those in the healthy volunteers group. The total locus length and enveloped areas in the patients were significantly higher than in the healthy volunteers. These results suggest that the patient may show head rotation abnormalities, even if the balance function is considered to be normal.
