Disturbance of balance in idiopathic Parkinson's disease (IPD) has a significant effect on disability. Yet the underlying mechanisms and the contribution of age-associated comorbidity to dysequilibrium are unclear. In this study, static posturography was performed in 30 healthy controls and 40 patients with IPD. Comparison of sway during quiet stance did not show significant differences between patients and controls. Multiple linear regression analysis was used to identify factors responsible for the considerable interindividual variance in patients. Results of the pull test, CT-verified cerebral microangiopathy, dementia, and age were assessed, but only cerebrovascular comorbidity contributed significantly to variance. Apart from increased sway, patients with coinciding cerebral microangiopathy (n = 20) more frequently had a history of falls or pathological responses in the pull test. The present results suggest that cerebrovascular comorbidity enhances dysequilibrium in IPD. Pathological sway in IPD can indicate comorbidity and may have implications for further diagnostics.
