Introduction: Postural instability is one of the most disabling features of Parkinson's disease. Objective: To evaluate postural balance in Parkinson's disease. Methods: Thirty patients with Parkinson's disease were compared with controls using Tetrax™ interactive balance system posturography. Results: For different positions, patients with Parkinson's disease showed a significantly higher weight distribution index, fall index, Fourier transformation at low-medium frequencies (F2-F4), and significantly lower right/left and toe/heel synchronization versus controls. Conclusion: Postural imbalance in Parkinson's disease patients is characterized by the abnormalities of weight distribution index, synchronization index, Fourier transformation index, and fall index as measured by Tetrax™ posturography.
