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.
