Mechanisms of cervico-vestibular-oculomotor disorders at the early stages of Parkinson's disease.
We studied the interaction of the oculomotor, cervical, and vestibular systems using a specially developed technique. A series of two tests were performed on 26 healthy subjects and 42 patients with stages I-II Parkinson's disease receiving and not receiving treatment. In coordinated tests, all amplitude-time characteristics of patients significantly differed from those in healthy subjects. Possible mechanisms of cervico-vestibular-oculomotor disorders are discussed.
