Relationship between Severity and Equilibrium Disturbance in Patients with Spinocerebellar Degeneration

Spinocerebellar degeneration (SCD) is severe and progressive disease with various symptoms. There are many reports describing the results of postural sway test, opto-kinetic pattern (OKP) and eye tracking test (ETT). However, there are few reports about the relationship of these findings to the severity of SCD. Therefore we recorded stabilometry, optokinetic pattern (OKP) and eye tracking test (ETT) in 7 patients of SCD. Results showed that the sway area of postural sway test and the slowest phase velocity of OKP were associated with the severity of SCD. Therefore it is suggested that postural sway test and OKP are methods of determining the severity of SCD.
