特発性脊柱側わん症と重心動揺検査

Abstract

The equilibrium funciton of 24 patients with idiopathic scoliosis was examined by stabilometry and other equilibrium tests (Romberg test, Mann test, gaze nystagmus test, positional and positioning nystagmus test, eye tracking test and optokinetic nystagmus test). In the group aged 10 to 15 years (18 patients), there was a fairly high correlation between the magnitude of Cobb's angle and the area of center of gravity movements. The magnitude of spinal rotation, as well as that of Cobb's angle, correlated well with the area of the center of gravity movements. On the other hand, in the group over 15 years of age (6 patients), the area of the center of gravity movements showed no significant correlation with Cobb's angle or spinal rotation. Eight of 24 patients (33%) had abnormal findings in the Mann test. Four of 24 patients (17%) showed diminution in the optokinetic nystagmus test. The other test results were normal in all patients. We conclude that stabilometry is a more quantitative test of equilibrium function in patients with idiopathic scoliosis than are other tests.
