A model for multisystem evaluation treatment of individuals with Parkinson's disease

In this article, we present a model of Parkinson's disease based on pathophysiology, impairments, and disabilities. The model provides a format for deciding what to assess, for interpreting assessment findings, and for deciding which impairments can be corrected by physical therapy intervention and which cannot. From the model, we can predict effective treatment approaches. We can also use the model to identify specific research questions related to the efficacy of physical therapy intervention.
