Bradykinesia Subscale Administered Alone Versus Regular Administration: Psychometric Properties

The purpose of this study is to examine whether scores on questionnaires that rate how much Parkinson's Disease (PD) has slowed movements of the body differ when the order of the questions are changed. The consistency and accuracy of the questionnaires will also be examined. It is hypothesized that there will not be a difference.
