Comparison of biomechanical and clinical assessment of postural stability in Parkinson's disease

Introduction: Postural instability is a common problem in Parkinson's disease (PD). To get information about the individual risk of falls assessment of postural stability is an important feature in prevention and rehabilitation programs. The retropulsion test is commonly used to rate postural. But the value of this clinical test is limited by the lack of normative data and the difficulties in standardizing it across different subjects (Bloem et al. 1998, Marchese et al. 2003). Our specific purpose was to investigate the relationship between the retropulsion test and more objective analysis. Fig. 1 Tab. 1 Biomech…
