The aim of study was to investigate stabilometric parameters of 20 untreated patients with PD, stage I, the mixed form, at stabi-lometric complex ST-150. Were used to assess static stability in the vertical position during quiet standing with eyes closed and open and dynamic in the execution of the combined samples. On the complex " VZOR " recorded eye movements and head when the retention test eye on the fixed and mobile targets with horizontal movements of the head (from shoulder to shoulder) in the sitting position. In I stages of PD, there is a deterioration in sustainability in the form of increasing the area stabilogram and work to retain balance. All patients had one or both of the above figures differ from the rules laid down in the program stabilometric STPL, when performing tests with feedback, and when the Romberg test with open and closed eyes, these figures differ from the norm in 18 patients. The results obtained with the help of hardware-software complex "VZOR" pointing to the violation of the cervico-vestibular-oculomotor interactions in the form of lower amplitude and frequency of head movements, increasing mismatch between eye movements, eye movements and head, as well as eye deviation from a straight line of sight to the target fixation.
