Comparative study of posturography and electrooculography in at-risk subjects for Huntington's disease

A simultaneous blind study of posture and eye movements was undertaken in 9 subjects at risk for Huntington's disease. After quantitative evaluation of the postural and electrooculographic abnormalities, the subjects were subdivided into subgroups, and the results were compared to test the relationship between the two methods. There was a significant correlation between the two evaluations. 5 of the 9 patients had evaluation scores which reflected abnormalities similar to those observed in patients suffering from Huntington's disease. These preliminary results suggest that posture and eye movement recordings could be tested for their predictive value in Huntington's disease.
